V3.2 Highlights - Improved Usability
•Ability to export/import a PipeLay project file to/from XML/text files – Allows for customised macros or scripting of model and analysis inputs independent of the PipeLay user interface. Such macros or scripting can be done using Excel, Python, Matlab©, or other similar means and it empowers users to further automate their installation analyses.
•Command line options for running analyses without opening project files – Again, enables external scripting of analyses batches and queues, which helps users to build their own automation tools around PipeLay.
•Direct vessel movement parameters on the analysis component – You no longer have to use vessel offset components to statically move the vessel during installation stages, instead the movements can be specified on the parameters tab of the analysis component. This gives greater flexibility to multi stage analysis where the level of movement varies from one stage to the next.
•Automatic free rotation angles for non-linear flex joints – Suitable moment-angle curves for flex joints can be generated by the user interface to allow free rotations up to a set of pre-defined limiting angles. This represents an efficient method for creating hinges along a floating stinger and reduces the need for external spreadsheets to calculate suitable non-linear curves.
•Option to specify stinger flex joint curves relative to the horizontal rather than to initial orientations – Moment-Angle curves for flex joints have in the past always had their origin (undeformed orientation) coinciding with the articulated section orientations specified on the stinger component. This meant if you changed the section orientations then the flex joint curves may have also needed changing so as to maintain overall rotational consistency. Now there is an option to force the curves to always be relative to the horizontal and independent of initial orientations.
•Upgraded examples set – More realistic specifications and application of modelling best practice throughout, which makes the new examples set a more valuable reference and template for users.
•Criteria tension can be used as a replacement for the expected tension on stress-strain materials – The maximum allowable tension criteria in an installation stage can automatically be used to convert material stress-strain data to pipe moment curvature data, rather than the expected tension input on the material component, which must be changed by the user for each different analysis.
•Ability to specify joint lengths and field joint cut backs in the calculation of average pipe section weights – Pipe section components now allow you to define the expected length of a pipe joint as well as the length of any coating cut back. These inputs adjust the calculated average pipe section weight to reflect the presence of field joints between coated portions.
•Loads can now be applied to internal line connections even when the connections themselves are not used in the model – Allows for placing point loads at arbitrary positions along the line without having to connect secondary components to the line. In previous versions loads at internal connections were only generated when the connections themselves had something connected to them.
•Accumulated length column on the line stack-up – Shows the gradual build up in overall length as the stack-up is built. This can help clarify the net effect of adding more pipe joints/sections to a stack-up.
•Remove all button on analysis component tabs and disable preview option on installations stages tab – Each of the stage lists on the analysis component can emptied in a single step using a remove all button. Also, the stage preview on the installation stages tab can be disabled if it is taking considerable time/resources to finish processing a model.
