Sector 05
Offshore Wind & Renewables
A target market where our floating, mooring and subsea-cable depth transfers directly into fixed and floating wind. Fixed and floating foundation structures, offshore substation platforms, mooring and station-keeping, inter-array and export cable engineering, and T&I for offshore renewables.
Capabilities
Foundation & Platform Structures
- Fixed wind foundation design — monopile, jacket, gravity base (SACS / ISO 19902)
- Floating wind platform structural design — semi-sub, spar, barge-type
- Offshore substation platform — structural design, topsides integration
- Fatigue analysis — wind-driven cyclic loading, DNV-RP-C203
Mooring & Station-keeping
- Mooring system design for floating wind — catenary and taut-leg (DNVGL-OS-E301)
- Coupled time-domain mooring analysis — OrcaFlex
- Mooring fatigue — line fatigue, shackle and connector checks
- Station-keeping and dynamic positioning interface
Cables & T&I Engineering
- Inter-array and export cable on-bottom stability — and protection engineering
- Cable route engineering — burial and rock-dump design
- Transportation and installation analysis — foundations, cables, substation topsides
- Marine Warranty Survey (MWS) packages — for offshore renewables installations
