V3.2 Release Notes

Previous page Next page

Wood Group is proud to announce the release of PipeLay Version 3.2. This latest version incorporates a variety of exciting new features and improvements that will offer substantial benefits to our PipeLay user base. Note that since the original release of Version 3.2 a new maintenance update has been issued, which provides further enhancements as listed in the bottom section of this article.

The development scope for Version 3.2 was established through active client consultation and feedback. We believe this active approach ensures that our PipeLay product continually evolves to meet the needs of the industry.

Many of the additions in Version 3.2 provide increased productivity for users in terms of improved usability, enhanced modelling, reduced run times, improved robustness and additional integrated post-processing. Such productivity gains deliver significant add valued in today’s oil and gas market.

The main feature highlights of the latest version are summarised as follows:

Enhanced Modelling

Radii of curvature and support elevation optimisation can be applied to hinged and articulated stingers

Optimum net buoyancy calculation to achieve desired orientations for articulated stinger sections

New Jonswap and Torsethaugen random sea wave specifications

Alternative calculation of water absorption for external coatings that only affects submerged sections

Option to account for the pipeline contact diameter on seabed rather than just having centreline contact

Improved Usability

Ability to export/import a project file to/from either XML or text based files for external scripting of inputs

Command line option for running analyses without opening project files – Allows for external batch files

Direct vessel movement parameters on analyses without the need for dedicated offset components

Automatic free rotation angles for non-linear flex joints allowing for the quick specification of rotation stops

Option to specify stinger flex joint curves relative to the horizontal rather than to initial orientations

Upgraded examples/templates set to give greater realism and to reflect modelling best practice

Criteria tension can be used instead of a direct expected tension input on stress-strain materials

Ability to specify joint lengths and field joint cut backs in the calculation of average pipe section weights

Loads can be applied to internal line connections even when the connections are not used in models

Accumulated length column on the line stack-up showing the net build-up of pipeline length

Remove all button on analysis component tabs and disable preview option on installations stages tab

Additional Integrated Post-processing

Excel© Add-In to directly access and post-process analysis databases without using PipeLay

Statistical and snapshot plots of support reactions and separations

API-RP-1111 buckling code checks

Selectable format for tabular output; either stress or strain based

Excel based summary report file

Select all components option available on post-processing and code checking dialogs

Velocities and accelerations can be included in the dynamic analysis databases for custom plots

Reported bending stresses/moments for sections with coating stiffness are now only for the steel wall

Progress summary for generation of dynamic tabular output files

Increased Robustness

Multi pass criteria analysis ensuring optimisation is done on an incremental and stable basis

Option to use a stable linear axial stiffness when specifying non-linear stress strain material curves

Reduced Analysis Run Times

Improved code efficiency leading to general improvements in analysis run time (10%-15%)

Dedicated 64-bit version of PipeLay leading to considerable reductions in post-processing times (20%-25%)


V3.2.2 Maintenance Update

The main highlights of the newest update are summarised as follows. More detailed descriptions are provided in a separate article.

Improved Analysis Run Times - Optimised software code for checking support contact during dynamic analysis leading to corresponding run time improvements of up to 40%-50%

Integration with New WebHelp Resource - The new WebHelp content can be accessed via the Help function in PipeLay. The content provides a fully integrated documentation set that will replace the old User, Reference, Examples and Best Practice manuals

General Post-processing Enhancements - Which includes:

oExpanded static solution summary in Tabular Output provides additional useful results

oIdentification of Governing Sagbend Node, Touchdown Point and Overbend-Sagbend Transition in Tabular Output

oResults tab remembers previously selected stage number after navigating away

Fault Fixes - 5 minor and 1 trivial fault fixes
