OrcaFlex

OrcaFlex® is the world's leading package for the dynamic analysis of offshore marine systems.


An OrcaFlex model of an FPSO system with a releasable turret.

Summary of key features
- Fully 3D, non-linear, large displacement analysis.
- Consistent and robust modelling of compression and snatching.
- Fully coupled tension, bending and torsion.
- Bend Stiffener / Tapered Stress Joint model generation.
- Rayleigh damping.
- Highly robust and accurate finite element formulation.
- Choice of implicit or explicit time integration methods (only peer group product with this capability).
- Fully coupled vessel/line analysis.
- Flat, 2D profile or 3D seabed surface.
- Linear elastic or non-linear hysteretic soil model.
- Non-isotropic Coulomb friction for a broad range of contact objects.
- Best of class fully interactive GUI.
- System visualisation as either wire frame or shaded view with perspective and hidden line removal.
- Modal analysis.
- Contact and clearance analyses.
- Fatigue analysis (regular, rainflow and spectral).
- Full environmental description including wave spreading.
- Vortex induced vibration analysis (VIV).
- Parallel processing to take advantage of multi-core and multi-processor hardware.
- Wake Interference Modelling (Huse, Blevins, User Specified).
- Automation facilities for parametric, sensitivity and loadcase studies.

Analysis
- Full 3D modelling.
- Complete and partial quasi-static analysis.
- Extremely quick and robust static analysis.
- Time domain dynamic analysis with ramp-up (to minimise starting transients).
- Non-linear large displacement analysis, including line compression and snatch loads.
- Modal analysis.
- Contact, clashing and clearance analyses.
- Fatigue analysis (regular, rainflow and spectral).
- Fully coupled tension, bending and torsion.
- Vessel manoeuvres (forward speed and turn rate).
- Surface piercing fully modelled.
- Line setup wizard to set line lengths for specified tension or top angle.

Applications
- Risers.
- Moorings.
- Instatllation Analysis.

	August 2011: PDL win Shell framework agreement. PDL engineers will provide advanced FEA and CFD analysis support to the Shell UK engineering team on the Brent Decommissioning project. PDL win BEL Valves order. PDL engineers to provide complementary FEA support to the BEL Valves engineering team on the BP Shah Deniz project. PDL invest in additional ANSYS AutoDYN mine blast analysis capability and training. PDL engineers to undergo a 3 day intensive training programme at the ANSYS AutoDYN training centre in Horsham. PDL attracts Durham University’s finest! Elizabeth Waterman, Stuart Rich and Peter Ward join the PDL engineering team having graduated with a Masters degree from the prestigious School of Engineering and Computing Science at Durham University in June of this year. July 2011: PDL sign a memorandum of understanding with Mott MacDonald. PDL and Mott MacDonald will collaborate on the development of an advanced 3D CFD modelling capability that will provide wind farm developers and financial institutions with an increased insight into the effects of complex terrains on the predicted energy yield values for onshore and offshore wind farm sites. PDL win CTC Marine Projects contract. PDL engineers to provide structural engineering and marine operations support to the CTC engineering team on the Greater Gabbard Cable Deployment project. PDL awarded NDSL contract. PDL engineers to provide advanced CFD analysis support to the NDSL engineering team on the Dounreay RHILW Stores project. June 2011: PDL awarded a significant TECHNIP contract. PDL engineers will provide advanced finite element analysis support to the DUCO Technology Development Team throughout 2011. PDL attend the Subsea NE conference in Newton Aycliffe. The conference will focus on export opportunities for UK companies in Brazil and Nigeria. PDL invited to join a special interest Offshore Renewables Group. The Offshore Renewables Group will ensure that the significant capabilities of companies located within the North East of England are presented in a coherent manner to ensure that the region plays a pivotal role in national and international offshore renewable projects. May 2011: 2011 was another record year. Financial results for the year ending May 2011 show a 38% increase in turnover and 140% increase in net profit. Further growth in sales and net profits are expected over the next 12 months in-line with the strategic business objectives. PDL invest in Abaqus software and training. PDL engineers attend a 5 day intensive Abaqus training course at the PDL office in Hexham. PDL present a technical paper at the ANSYS Renewable energy conference in East Kilbride. The paper provides an insight into the development of an advanced 3D subsea site characterisation tool capable of identifying these most productive locations for subsea tidal turbine deployment. PDL attend the All Energy 2011 conference and exhibition at the Aberdeen Exhibition and Conference Centre (AECC). PDL attend the Magnox Supplier Forum event in Llandudno to hear about the near term work plans for the Magnox sites. BSI Management Systems external auditors award the PDL Quality Management System a clean bill of health at the 3 year strategic review. The PDL QMS was awarded ISO 9001:2008 accreditation for a further 3 years. April 2011: The PDL Monitored Professional Development Scheme (MPDS) is awarded IMechE accreditation. The accreditation of the MPDS scheme by the IMechE is an integral part of the strategic intent to ensure that all PDL engineers have the opportunity to achieve Chartered Engineer (CEng) status in robust and timely manner.
