General

0.1. Introduction Pegasus has been developed by DNV GL to support recording and assessment of thickness measurement data. This can be done in two different ways: Either by entering measurement data into tables (the so called Lite functionality) or by assigning thickness measurements to an existing 3D model of the ship structure (the so called Full functionality). The program is protected by a license file which defines the scope of functionality. In particular the availability of Lite and Full functionality is determined by the feature releases of the license files. The main features of Pegasus are: 

Spreadsheet like tables, allowing easy data input and clear presentation of measurements results.



Comparison of the measurement data against the specific maximum allowable diminution of the respective structural part.



Dynamic hot spot list showing the most critical areas with respect to degree of corrosion.



Generation of reports in the format required by IACS1.



XML based data format for exchange, storage and transfer of thickness measurement data.

For the Lite functionality of Pegasus the measurement recording tables have been designed to simplify input of data as much as possible. Furthermore their layout is similar to the tables commonly used for TM reporting according to IACS. The main features of the Lite functionality are: 

The results of the comparison of the measurement data against the specific maximum allowable diminution are coloured in the tables according to the degree of corrosion.



The generated reports contain tables, assessment results as well as related documents, e.g. sketches.



Support for Enhanced Survey Program (ESP) assessment of corroded structures.



Support for Condition Assessment Program (CAP) of corroded structures

The Full functionality of Pegasus offers assignment of readings to the structural parts of the ship structure by user defined views of the 3D model. Subsequently a TM report according to IACS1 can be generated automatically. The main features of Pegasus Full functionality are:

1

IACS, Unified Requirements Z, Survey and Certification



Creation of printouts based on the 3D model to be used for the real measurement process.



Provision of approved scantlings for the structural parts by the 3D model.



3D views of the structure and measurements with a linked tabular measurement data representation. Changes in the graphical view are reflected in the list and vice-versa.



The results of the comparison of the measurement data against the specific maximum allowable diminution are coloured in the graphical view according to the degree of corrosion.



The generated reports contain the IACS required tables with automatically created sketches of the measured structure and assessment results.



Data Interfaces to POSEIDON to generate the geometry and the plates/profiles from the POSEIDON model and to transfer the measurement values to POSEIDON, if required.

0.2. What is new in Version 2.1? General 

Removed assessment criteria “I” (to be investigated). In case of local corrosion and critical assessment (“substantial” or “to be renewed) readings can be marked as “local corrosion” and will be reassessed with applicable corrosion tolerance.



UTM providers may change thickness tolerances. Changes of standard tolerances will be indicated in program and report (bold and italic font)



Statistical assessment of compartments according to Condition Assessment Program (CAP) possible



Checklist for UTM providers included



Double compartment assignment (front and reverse side) possible for CAP assessment.



Structural member template types defining corrosion diminutions can be extended by sub types

User Interface 

Hotspot and reading list filter revised for better usability



Sketches attached to tables can now be easily displayed within Pegasus.



Display of maximum diminution now also in percentage

0.5.9.2.

TM-Table Creation Options

Some TM-tables can be preconfigured according to the size of the ship. For instance the number of rows is known when the steel drawing of the ship is available (strake length in the TM-1). The same holds true for cross sectional tables TM-2(i) and TM-2(ii), see Figure 7.

Figure 7: Table options For tables of type TM-1, the default number of plates in strake fore and aft from amidships can be defined, see Figure 8. If the numbers to fore and aft end are different,

the maximum should be chosen. For example, setting this value to 5 will result in 11 rows, 5 forward, 1 mid ship, and 5 aft.

Figure 8: predefined number of plates in strake (for TM-1) For tables of type TM-2(i), the default number of strakes between stringer and centre can be specified, see Figure 9. For example, setting this parameter to 3 results in 5 rows for the TM-2(i): 1 stringer plate strake, 3 strength deck strakes, and 1 sheer strake.

Figure 9: predefined number of strakes TM-2(i) options For tables of type TM-2(ii), the default number of shell strakes can be specified, see Figure 10. While sheer strake and keel strake is fixed, the number of strake for side shell, bilge and bottom can be given. For example, 2 side shell strakes, 2 bilge strakes and 2 bottom platting strakes, result in 7 (keel strake taken into account) rows in the TM-2(ii) form.

16 / 102

Figure 10: TM-2(ii) options The behaviour of the table editing can be changed using the last two options. Movement of the cursor on pressing the enter key can be switched by the last option. The cursor can move top to bottom or left to right on pressing enter. When left to right movement is chosen, the cursor moves into the next line when leaving the last editable cell in a line.

Figure 15: Specifying a date via calendar Once a date is set it can be changed using the arrow keys on the calendar. For this select the date field by left-clicking and navigate to the according entry for year, month or day with the left and right arrow keys.

Rule Set input: If the Pegasus Lite project was not provided by DNV GL the applied rule set can be changed by clicking the Change button left beside the name of the current applied rule set. This will open a window listing all possible structural members that can be used for table based measurement recording. Clicking the Change button of this window will open a window allowing the selection of the rule set to apply (see Figure 16).

Figure 16: Change of Rule Set

Editing Structural Member Types: Pegasus Lite functionality comes with a predefined list of structural member types and referring rules for the computation of the maximum diminutions. These predefined structural member types can be extended by subtypes enabling the definition of different corrosion margin rules for structural parts of the same structural member type but located at different areas.

22 / 102

Figure 17: List of predefined structural member types Using the insert and remove line buttons of the local toolbar (see Figure 17: List of predefined structural member types) allow creation and deletion of structural member subtypes. The name of a subtype can be chosen arbitrarily, the diminution formula can be defined by the following syntax: GL

Compute maximum allowed diminution acc. to legacy GL formula (default)

mm

Maximum allowed diminution is defined by an absolute value, e.g. 1.5mm

%

Maximum allowed diminution is defined by percentage of the original thickness, e.g. 20%

%+-mm Maximum allowed diminution defined as combination of absolute and percentage value, e.g. 20% + 1mm

Note:

This feature is only available for DNV GL users having a special license file.

2.2. Compartments For some kind of measurement campaigns, e.g. CAP and ESP, it’s necessary to provide a statistics based on compartments - hence there is a need to assign readings to compartments.

In case of table based recording using Lite functionality this requires a manual assignment of readings to the related compartment(s) in the different measurement tables TM-xx.

2.2.1. Compartment Definition Creating a new project for table based recording using Lite functionality there won’t be any compartment definition unless the project is provided by DNV GL in the case of a measurement campaign according to TM-7S31. Every compartment in scope of measurements has to be created. That can be done via the compartment menu or via the local toolbar button of the TM-Tables (see Figure 18). Using the local toolbar button opens a dialog; see Figure 19, where the name must be specified. The type (or purpose) of the compartment has to be chosen from a predefined list.

Figure 18: Compartment creation via local TM-Tables toolbar

Figure 19: Compartment creation dialogue All compartment definitions are contained in a table accessible via the Compartments menu provided by the General Data panel, see Figure 20. Previously defined compartments can be edited or deleted while new compartments can be created directly in the table.

2.2.2. Compartment Assignment with Lite Functionality In order to assign a compartment to a reading with Lite functionality the compartment columns must be enabled (show/hide compartment column toggle), see Figure 21.

Figure 21: Compartment results, additional compartment columns

Left-clicking a compartment cell and selecting a defined compartment from the dropdown list assigns the reading to a compartment. In order to assign the same compartment to several readings, simply select all cells or the whole column. Then use the set data function to assign a value simultaneously. The principles of compartment assignment will be defined by the attending surveyor.

2.3. Campaign Details General information about the measurement campaign is recorded in this form. Most input fields can be edited if necessary at any time, see Figure 22. Specific information about the input fields is provided below

TM-Tables

According to the IACS3 thickness measurements have to be reported in specific forms. In case of Lite functionality the software supports the IACS reporting forms TM-1, TM-2, TM-3, TM-4, TM-5, and TM-6. For bulk carriers additional forms TM-7 and TM-7S312 are supported. Forms TM-1 to TM-7 can be generated by the user. Due to precalculations needed to set up the TM-7S31, this form will be provided by DNV GL to the ship owner for every single ship prior to the measurements. (In case of Full functionality the IACS tables TM-1, TM-2, TM-3, TM-4, TM-5, TM-6 and TM-7 will be created automatically from the readings assigned to the 3D model nevertheless the TM-tables can also be created manually e.g. for parts of the structure which does not exist in the 3D model.) Every reading is located on a structural part (plate/stiffener) belonging to a structural member (main deck, shell, etc. ). For each plate or stiffener the maximum allowable diminution is determined from the respective structural member and the original thickness. Note:

In case of local corrosion the corrosion margin is set to 20% of the original thickness as default. Depending on the type of corrosion, this local corrosion margin can be overwritten as defined by the attending surveyor.

The necessary steps to establish the assignment for different table types are explained in detail in the following sections. Note:

All values have to be entered with decimal delimiter according to country specific local, i.e.. 10,5 in German and 10.5 in English. All values have to be entered in [mm]. The original thickness has to be entered in accordance to the thicknesses approved by DNV GL for the vessel to be measured.

Measurement assessment For some measured values a rating symbol in the Diminution column A is shown. This symbol is used to indicate a specific degree of corrosion or a warning that is related to this measurement, for example a measured value that exceeds the original thickness or a case where the maximum diminution can’t be determined correctly, see Table 1. Substantial corrosion Substantial Corrosion is an extent of corrosion such that assessment of corrosion pattern indicates a wastage in excess of 75% of the maximum allowable diminution, but within acceptable limits. Structural part has to be replaced In case of corrosion which exceeds the maximum allowable diminution the corresponding structural part has to be renewed. Measured value exceeds original thickness maximum diminution can’t be determined from

3.1. Table Creation Selecting TM-Tables from the project panel will open the menu for recording the thickness measurements based on tables. The IACS3 compliant reporting tables can be generated by the local toolbar of the Tables panel, see Figure 23. The different types TM1 to TM-7 are available according to the ship type. Note:

TM-7 is not available for tankers.

Figure 23: Table creation via toolbar A new created table opens immediately. Existing tables are listed in the table tree of the measurement Table panel. They can be opened by a single or double left-click. Note:

For each table type, the tooltip specifies which structural members are supported

3.2. Table Basics All tables are organized in the TM-Tables panel as tree, see Figure 24. Single or double left-click on each node opens the table and places the cursor at the top left cell.

TM-7S31 Cargo Hold Side Shell Frames

Pre-calculations are needed to set up the TM-7S31, furthermore the scope of the measurements is specified by DNV GL. Hence prefilled tables of this type will only be provided by DNV GL to the ship owner for every single ship prior to the measurements. These tables must be used to guarantee a complete and consistent assessment. TM-7S31 tables, see Figure 36, shall be used for recording of thickness measurements of cargo hold transverse frames of bulk carriers under IACS UR S31.

Free text comment regarding this measurement table.

Table columns Measurement Values

Individual measurements, up to 10 readings per item can be entered

A mean value is calculated automatically from the individual measurements and shown in column tM.

3.4. Data Import In most cases measurement data are entered into the tables only after the measurement campaign has finished. In order to support recording of data by several persons, the software allows file merging in case of Lite functionality. To merge two or more files it is mandatory that all files have the same Main Particular data. At least IMO number, ship name and applied rule set and the internal measurement campaign id must be identical. The following procedure is highly recommended for a smooth data import: 1. Create a basic project file including all ship specific general data (to be defined in the Main Particular and Compartments sub-items of the General Data panel). 2. Create a copy of this file for all involved persons. 3. After finishing data collection, gather all files at a single place and import them back to the basic file, one-by-one. The import comprises transfer of all tables, attachments corresponding to tables and compartment definitions. 54 / 102

To run the file import, select “Import …” in the File menu, see Figure 37. A file dialog will open allowing selecting the file to be imported.

Figure 37: Data import Note:

The merging of files is only supported for pure table based measurements (Lite functionality)

TM-3D-Model

Performing 3D based measurement recording, i.e. using Pegasus Full functionality, requires a model of the ship structure given in HCM format. This HCM format describes the structural model in terms of plates and stiffeners with 3D shapes, properties and affiliation to structural members and compartments4. Total Model

Figure 38: Principal 3D Model setup as defined by the HCM standard

Note:

The assignment of structural parts to compartments and structural members is model inherent and is not part of Pegasus. Hence Pegasus will represent compartments and structural members as they were defined by the model setup.

Assigning readings to this 3D model requires a graphical view displaying the structural parts where thickness measurement shall be carried out. Within this view readings are created by mouse click on the shown structural parts storing information about the location of reading (3D coordinates) and the referring structural part with approved thickness and maximum allowed diminution. Views can be arbitrarily created and stored with Pegasus to allow specific measurement recording.

Overall View

Strake View Figure 39) Different views on a 3D model Note:

Cross Section View

Compartment View

A view is just a utility allowing recording of readings independent from any assessment or reporting requirements. I.e. a view can be deleted without any impact on recorded readings, their assessment or report generation.

4.1. View Creation Selecting 3D Views (see above) from the project panel will open the menu for recording the thickness measurements based on a 3D model. Views can be created by the local view toolbar providing four methods for convenient view creation with minimum data input: Cross section view, strake view, compartment view and an overall view. Each view can be modified after creation using the 3D Part Filter, explained in section 4.2.1.1 to adapt the view to the necessary requirements, e.g. adapt a view to have a closer look into structural details.

Figure 40: 3D View creation via toolbar

4.1.1. Cross Section View Creation A cross section view showing the ship structure within a dedicated frame range or at an exact frame position and can be created by the cross section view wizard in figure below.

Figure 41: Cross section view creation via toolbar The frame position resp. the frame range can be defined by the menu below.

Figure 42: Cross section view creation Xmin

Frame number defining the foremost x coordinate of the cross section. If checkbox not ticked, frame number is set to the minimum frame number of the model.

Xmax

Frame number defining the aftermost x coordinate of the cross section. If checkbox not ticked, frame number is set to the maximum frame number of the model.

Note:

Intermediate frame positions can be entered by +/- , e.g. 72 +200 defining the position at 200mm in front of frame 72. If Xmin and Xmin are set to the same frame number an exact cross section view (with zero x extension) will be created.

Figure 50: Usage of filter for selection of shown structural parts These filters can be configured by the 3D Part Filter panel shown in figure Figure 51.

Figure 51: 3D Part Filter panel consisting of Bounding Box, Compartments and Structural Member filter lists. The Bounding Box filter allows restraining of structural parts to be displayed by the following settings:

Xmin

Frame number defining the foremost x coordinate of the displayed model. If checkbox not ticked, frame number is set to the minimum frame number of the model.

Xmax

Frame number defining the aftermost x coordinate of the displayed model. If checkbox not ticked, frame number is set to the maximum frame number of the model.

Ymin

Coordinate defining the outermost starboard y extension of the displayed model. If checkbox not ticked, coordinate is set to the minimum y coordinate of the model.

Ymax

Coordinate defining the outermost portside y extension of the displayed model. If checkbox not ticked, coordinate is set to the maximum y coordinate of the model.

Remember to select at least one Structural Member filter to create a view with visible parts. The Compartments filter does not influence the visibility of the structural members.

Note:

The Bounding Box, Compartments and Structural Member filter lists are interconnected. I.e. an activated bounding box filter restrains the compartment and structural member filter list to those compartments and structural members having structural parts lying in the active bounding box. An activated compartment filter restrains the structural member filter list furthermore to those structural members having structural parts belonging to the active compartment(s).

Figure 55: Folder organization of views 72 / 102

4.2.4. Reading Editing Once a view is created, a reading can be created on any displayed structural part by left mouse click after activating the reading creation mode in the 3D toolbar (see section 4.2.1.2.) The created reading will be displayed as small icon on the structural part and as new row in the view list showing the referring properties of the reading. Depending on the kind and spatial orientation of the structural part, different shapes of icon will be used: Reading is on longitudinal plate Reading is on transversal plate Reading is on longitudinal stiffener Reading is on transversal stiffener

Readings are created with an undefined measured thickness value, indicated with a white coloured icon and value UNDEF in the referring cell in the view list. After a reading is created, the focus will be changed from the graphic to this cell to facilitate measurement value entering. If a thickness value is entered for the reading, the icon will be coloured according to the following scheme:

Figure 56: Colouring scheme for reading icons and structural parts Readings can be deleted either by selecting the referring row in the view list and pressing the DEL key or by activating the reading deletion mode in the 3D toolbar (see section 4.2.1.2.) and selecting the reading to be deleted in the graphic. Readings can be moved within the referring structural part by activating the reading movement mode in the 3D toolbar (see section 4.2.1.2.), selecting the reading in the graphic and move it by drag and drop to the new position. If the key is pressed

during this operation, the reading can also be moved to any other structural part in the graphic.

Results

Selecting Results from the project panel provides access to different lists comprising readings with a degree of corrosion beyond predefined limits as well as a compartment based statistic, see Figure 57. These lists are dynamic, i.e. they are updated every time a new reading is entered.

Figure 57: Results sub-panel

5.1. Readings The reading list (see below) shows all readings defined in the project (with or without defined measurement value) and provides individual properties for all readings like comments, coordinates (if present),name of the structural part or compartment assignment. This list can be filtered by predefined filters and sorted by each reading property.

5.3. Hotspots TM-7S31 The hotspot list for the TM7S31 tables comprises side shell frames in single side skin bulk carriers which have to be renewed or recoated according to the IACS Unified Requirements S31 and GL-corrosion criteria, see Figure 60. Ratings for side shell frames to be renewed are generated according to both the IACS UR S31 requirements as well as the GL-corrosion criteria whichever criterion is stricter. This hotspot list is only available for readings recorded in tables of type TM7-S31 using Lite functionality. The hotspots list can be sorted in ascending or descending order by each column by double clicking on the column header. Sorting by column Frame No yields the default plate grouped ordering.

5.4. ESP Assessment For ships carrying the class notation ESP (Enhanced Survey Program) a survey scope in accordance to IMO-Resolution A.744(18) as amended is required. Notation ESP will be assigned to oil tankers, chemical tankers, bulk carriers and combination carriers in accordance to IACS UR Z11. ESP requires among other things the determination of maximum and average thickness diminution for defined locations and areas. Pegasus Lite functionality helps to evaluate these statistical values from the recorded thickness measurements stored in the thickness measurement tables. The ESP assessment is accessible as icon of the Result panel and creates a window with input and output tab.

Table 2: ESP locations for which maximum and average thickness diminution may be calculated The location of Transverse Section, Wind and Water Strakes, Superstructure Deck Plating and Deck Plating and Under Deck Structure inside line of Cargo Hatch Cover will be defined by the ESP assignment table shown in Table 2. For each of these ESP locations the TM tables to be considered can be selected by a check box. Selecting TM tables for different frames for the Transverse Section area will result in maximum and average thickness diminution output for each frame.

Figure 62: Assignment of TM tables to special ESP locations The assignment table can be sorted with respect to a column by double clicking on the column header. For instance all TM tables referring to a special frame can be easily accessed by sorting the assignment table according to the frame number. Additionally the assignment table can be filtered according to the ESP locations currently worked on. Hide / Show columns used for table assignment to a transverse section Hide / Show columns used for table assignment to the wind and water strake Hide / Show columns used for table assignment to a super structure deck plating Hide / Show columns used for table assignment to deck plating and under deck structure inside line of cargo hatch cover

Note:

For correct ESP assessment it is mandatory to use TM tables as intended by IACS and to assign each reading to a compartment!

5.4.2. ESP Location Result For each ESP location as defined in Table 2 the maximum and average diminution in terms of percentage to the original thicknesses (“ESP values”) are shown in the output tab of the ESP assessment. The ESP results are grouped according to the defined 84 / 102

compartments, the transverse sections for each frame and the automatically created ESP locations Keel Plate, Bottom Shell Plating, Bilge Plating, Side Shell Plating, Sheerstrake, Strength Deck Plating, Stringer Plating. For each compartment the referring ESP values of transverse webs (and adjacent structural members), shell frames and transverse bulkheads are listed (see Figure 63 ).

Figure 63: Maximum and average thickness diminution results for ESP areas Placing the mouse pointer over a cell of the “Areas” column will display a summary of the considered TM table as tooltip. Additionally the ESP output table can be filtered according to the different ESP locations: Hide / Show rows showing ESP values for transverse sections Hide / Show rows showing ESP values for the wind and water strake Hide / Show rows showing ESP values for a super structure deck plating Hide / Show rows showing ESP values for deck plating and under deck structure inside line of cargo hatch cover Hide / Show rows showing ESP values for the automatic created ESP locations Hide / Show rows showing ESP values for the compartments Hide / Show rows showing ESP values for the transverse bulkheads Hide / Show rows showing ESP values for the transverse webs (and adjacent

5.5. Statistics The scope of the measurement campaign as well as a distribution of readings according their degree of corrosion is provided by the icon Statistics of the Results panel.

Figure 64: Project statistic The distribution of all tables included in the project file according their types is shown on the right hand side. Detailed information about the readings are summarized on the top left hand side, see Figure 64. They are grouped according their degree of corrosion (normal, substantial, renewal required) and suspect groups like Unknown (no maximum allowable diminution available) and Negative (measured value exceeds original thickness). Some general information like number of compartments and number of available structural members and a file identification number (check sum) is shown as well.

86 / 102

5.6. CAP Assessment CAP assessment requires among other things a statistical assessment of the corrosion condition of compartments. Pegasus Lite functionality helps to evaluate these statistical values from the readings recorded in the thickness measurement tables. A prerequisite for this assessment is that the readings are assigned to the related compartments (i.e. if a reading is located on a structural part shared by two compartments it has to be assigned to both compartments, otherwise to only to one compartment).

Note:

This feature is only available for DNV GL users having a special license file.

5.6.1. CAP Results A list of all compartments is shown displaying the share of readings of in the compartments having different levels of degradation (see Figure 65: CAP Assessment). The degradation within a compartment is further itemized into the main structural elements Deck, Side, Bottom, Inner bottom, Inner Deck, Long. Bulkhead, Trans. Bulkhead, Internal Structure and Hatches&Coamings derived from the referring structural members of the readings (see Table 3: Mapping Structural Member Types to CAP Sub Structures)

Report Generation

TM reports can be generated by the Create Report icon of the Results panel (see Figure 67).

Figure 67: Report Creation Selecting this menu opens a dialogue (see Figure 68) where the filename and path of the report can be specified. “Save” creates a report in RTF (Rich Text Format). By default the report contains all tables and corresponding figures existing in the project. The sequence of the TM tables in the report is the same as under node TM Tables in the project tree.

Figure 68: "Save as" dialog for reports

92 / 102

In order to change the scope of the final report or to exclude all figures the “save as” dialog provides the Options… command to generate a user defined report. Figure 69 shows a sample scope selection dialog. It allows specifying which measurement tables are to be included in the report. Specific tables can be excluded by unchecking the according entries in the table. If figures shall not be included in the report uncheck the include figures option

Figure 69: Report options . If a standard RTF (Rich Text Format) viewer is installed on the system, e.g. MS Word, the report is automatically opened after the generation process for viewing, printing, and further processing. Note:

Page numbers are not updated automatically. When using MS Word select the whole document content by “CTRL+A” and update all field values “F9” in order to establish the correct page numbering.

Note:

Report generation will be denied for vessels with ESP class notation or subjected to the “Condition Assessment Program” (CAP) if not all readings are assigned to a compartment.

6.1. Report Configuration Performing 3D model based measurement recording, i.e. using Pegasus Full functionality, requires some configuration input to ensure a reasonable IACS conform thickness measurement reporting (see below).

Figure 70: Report configuration in case Pegasus Full functionality The following configuration input is needed: Preselected Frames for TM-2

Frame numbers where TM-2(i) and TM-2(ii) should be created. Frame numbers has to be separated by “;”. E.g. if Preselected Frames for TM-2 is set to 125;145 TM-2 will be created at frame 125 and frame 145 (if readings on relevant structural members at these frames existing)

Minimum # of MP for TM1…TM7

Minimum number of readings contained in referring TM table

Min. Long. Ext. Tolerance

Distance of minimum and maximum x-coordinate of a structural part defining if it is classified as transversal or longitudinal structural part. E.g. a plate extended from frame 100 to frame 100+500mm will be classified as transversal structural part if Min. Long. Ext. is set to 600mm and will be classified as longitudinal structural part if Min. Long. Ext. is set to 400mm.

Frame Selection Tolerance

Spacing around frame to assign readings to it. E.g. if Frame Selection Tolerance is set to 300mm and a reading to be reported in TM-3 is located at frame 112 +200mm will appear in TM-3 table at frame 112.

Bulkhead Clustering Tolerance

Spacing around a transversal bulkhead to assign readings to it. Especially important for corrugated bulkheads where readings are not located on an exact frame position in general.

11. FAQ Q: The page references in the generated report are broken. A: Page numbers are not updated automatically. When using MS Word select the whole document content by “CTRL+A” and update all field values “F9” in order to establish the correct page numbering. Q: Undo does not work. A: Due to the complexity of this problem, solution is only implemented partially. Full implementation is postponed for a later release. Q: How do I set several input field with the same value? A: Mark the cells in Question and then use “set data” from the context menu. Q: Where in TM–3 do I enter the Bottomshell, SHELL (as part of a ring measurement) A; According to IACS, shell elements are recorded in TM-2(i/ii) Q: “Chain Locker” (or other element) is missing. It is complicated to build these from single plates. A: Use TM-6 Miscellaneous. Q: Why can’t all elements of one cross section / Longitudinal oriented evaluation be recorded in only one TM table? A: The different tables are a strict implementation of the IACS tables. Q: Why can’t I find HP profiles in TM-Tables for profile measurement? A: Only the Profile position, not its type is recorded with Pegasus Lite functionality.
