Key skills are essential to Orwell Offshore in delivering to their Clients for which Orwell Offshore’s philosophy has been to develop skills and engineering in house. This approach is two-fold – staff and equipment.

High calibre staff are recruited who are encouraged to develop their skills and capabilities both in breadth and depth, supported by the company. Engineering staff are, however, not enough and Orwell therefore maintains a range of analytical and design tools.

Engineering Disciplines:

Naval architects
Structural engineers
Mechanical engineers
Piping engineers
CAD operators
Planning and Project Management

Analytical and Design Tools:

Naval Architecture: OrcaFlex, HydroStar, MOSES, GHS, HST, ARIANE-3D
Structural: STAAD Pro, ANSYS
Design: AutoCAD, SolidWorks

Using GHS hydrostatics software, Orwell Offshore are able to carry out stability studies ranging from the checking of single loading conditions for compliance with statutory stability requirements, to the production of full class approved Trim & Stability Books for FPSOs.

Hydrodynamic studies are carried out using a suite of software, based around Bureau Veritas’ HydroStar program. HydroStar is a three dimensional potential flow solver, capable of analysing floating bodies with or without forward speed in both deep water and in finite depth. It is also able to assess the motions of multiple bodies and the effects of their interactions on motions.

Using the vessel motions output from HydroStar, Orwell Offshore able to carry out studies on the operability and downtime of vessels in specific sea states and loading conditions, dynamic behaviour of vessels connected to mooring systems and vessels moored alongside quays or other vessels.

Mooring system design and analysis is carried out using the industry standard software packages ARIANE-3D and OrcaFlex. Both allow the dynamic modelling of complex mooring and riser systems. Orwell Offshore has experience not only in the design of mooring systems, but also the development of laydown and recovery procedures for moorings, as well as the development of operational guidance for safe operation whilst connected.

Ship structures are able to be analysed using ANSYS finite element software, to determine the strength of structures as part of vessel conversion projects.
