If the positive surge direction is stated as being “forward” then Flexcom will not perform any conversion. If the positive surge direction is stated as being “aft” then Flexcom converts the surge phase by subtracting 180 from it.

If the phases are stated as being relative to the “trough” then Flexcom subtracts 180 from all of the phases. RAOPhaseRelativeToConvention: It is assumed that this refers to the positive wave elevation.If the phases are stated as being in “degrees” then Flexcom will not perform any conversion. If the phases are stated as being in “radians” then Flexcom multiplies the phases by (180/pi). RAOPhaseUnitsConvention: It is assumed this refers to the units that the phases in the yml file are in.Otherwise if the option states that it “lags” Flexcom will not perform any conversion. If the option in OrcaFlex states that the phase angle “leads” then Flexcom will multiply all the phase angles by -1. RAOPhaseConvention: It is assumed that this refers to the positive rao phase angle of the RAOs in the yml file.If the waves are referred to in “frequency (Hz)” then no conversion will take place. If the waves are referred to in “frequency (rads/s)” then Flexcom divides them by (2*pi). If the waves are referred to in “periods” then Flexcom performs the following conversion (1/period). Flexcom converts the values referenced by this convention from the convention stated in the yml file to the Flexcom format. WavesReferredToBy: It is assumed that this option is a statement of what the units of wave period are for the RAOS in the yml file.No conversion will take place based on this convention but Flexcom will produce an error if either “max wave slope” or “wave steepness” is the stated convention. RAOWaveUnit: It is assumed that this is always set to “amplitude” and if not Flexcom produces an error.If they are stated as being in “degrees” then no conversion will take place. If they are stated as being in “radians” then Flexcom multiplies these rotational RAOs by (180/pi). RAOResponseUnits: it is assumed that this refers to the units in which the rotational RAOs are referred to in the yml file.All other formats are set on a file by file basis and the interpretation of the available options in OrcaFlex are as follows:.The definition of wave heading is transformed such that a 0 degree heading, which is incident on the stern in the OrcaFlex format, is incident on the bow in the Flexcom format.The conventions used in Orcaflex are as follows:

Flexcom can import RAO data from an OrcaFlex text data file (.yml) only. by extracting drag and added mass coefficients from CFD simulations or to specify dynamic loads to structural models).OrcaFlex models can be saved in either binary data files (.dat) or text data files (.yml). Our expertise in the global analysis work is further enhanced by our other core capabilities, which we can integrate to create higher accuracy models (e.g.
#Orcaflex software
Using this tool we are able to model the inherently non-linear response of subsea equipment in both the time and frequency domain and assess a diverse range of dynamic offshore marine systems in an efficient and productive way.Īs with any other engineering software, the true value that OrcaFlex creates is only accessible by having a deep engineering knowledge and experience, which is where we come in: we are expert users of the software and have a deep knowledge of the industry and regulatory frameworks (DNV, API, etc) and are internationally recognised as a leading authority in delivering advanced global analysis on increasingly complex engineering projects. OrcaFlex is a powerful tool that encompasses a large variety of objects and features which enable assessing complex systems and applications through a mathematical model.

Offshore marine systems design is a complex undertaking which is highly regulated and carries significant risk, and for which even small improvements can significantly increase safety and reduce costs.Īt PDL we undertake dynamic analysis of offshore marine systems using the world’s leading package software OrcaFlex in order to assess and optimise new and existing offshore marine designs and operations.
