SEADOG wave energy generation concept. The work include
structural and mechanical engineering design as well as
assisiting with DTI grant applications.

connections for the GM4000 semi-submersible drilling vessel
- strength and fatigue design.
Client: Global Maritime
· Carrying out detailed FEA of GM4000 well intervention
semi-sub vessel for strength and fatigue.
· Carried out dynamic explicit analysis (ABAQUS)
of a dropped container hitting concrete mattress protected
pipeline for the Buzzard project. All interacting components
were modelled separately and appropriate contact between
all parts, down to and including the seabed, defined. The
analysis was used to demonstrate the suitability of the
mattress protection system.
Client: Andrew Palmers Associates
· Carried out detailed solid brick element FEA using
ABAQUS for strength and fatigue analysis of the Cutter Project
sub-sea cast Wye Piece.
Client: London Marine Consulting Ltd
Carried out the detailed FEA, using ABAQUS, of the Chinguetti
project sub-sea Riser Connectors and their latching mechanisms.
The analysis included full modelling of the latch mechanism
and separate pull-in head arrangement - as an assembly of
parts spatially related through a variety of contact pair
Client: Marlin Submarines
Carried out strength analysis, non-linear material and geometry
- buckling collapse, of mini research submarine using ABAQUS.
The analysis also investigated the contact sealing around
the acryllic view ports.
Client: Global Maritime
· Expert Witness work - Carried out ship impact simulation
of the KURE bulk carrier. This involved modelling the full
ship with the mesh refined in the impact region. Dynamic
explicit was used to simulate the collision under various
conditions of impact velocity and trajectory, as well as
a full range of sensitivity studies to assess the effects
of varying damping, mesh density, friction, and material
