Design engineering and structural analysis for offshore structures
Structural design and analysis of fixed platforms, floating vessels and semi-submersibles, from the first model to the final code check, in SACS, ANSYS, MOSES, MAXSURF and STAAD.Pro.
- 4design codes: DNV-OS, ABS, NORSOK, ISO
- 3design methods: LRFD, WSD, limit state
- 5analysis tools, from SACS to STAAD.Pro
- 18+years in offshore engineering, since 2008
Six parts of every design engagement
From the first model to the final check, one team handles the whole design.
Structural modelling and FE analysis
Global and local models of the structure and its connections, built in SACS or ANSYS.
Design to recognised methods
LRFD, WSD or limit state design, chosen to suit the governing code and the owner's specification.
Code checks
Member and joint checks to DNV-OS, ABS, NORSOK and ISO, documented for the client's review.
Weight and material optimisation
Lighter structures that use less steel, without giving up capacity.
Fatigue analysis
Fatigue life of members and joints under wave and operational loading.
Load-out, transport and sea-fastening
Load-out and transportation analysis, with sea-fastening designed for the tow.
Pre-service, in-service and advanced

From your drawings to a checked design
- 1
Share drawings and loads
General arrangement and structural drawings, equipment weights, and the operating and environmental conditions.
- 2
Agree method and codes
We confirm the design method, governing codes, load cases and deliverables in a written proposal.
- 3
Model and analyse
Global and local models in SACS or ANSYS, run against every agreed load case.
- 4
Check and optimise
Code checks on members and joints, then optimisation of weight and material.
- 5
Report and drawings
Calculation report, recommendations and, where in scope, reinforcement details and detailed drawings.
Design modifications we have delivered
SMIT bracket relocation
Relocation of an existing SMIT bracket with a 150 MT safe working load to the port aft area.
ST-80 floor socket at the drill floor
Structural response of the existing drill floor with the modifications needed to install an ST-80 floor socket.
Airman compressor platform
Structural check of a new main-deck platform for installing an Airman compressor.
The tools we design with, and teach
Your structure is designed by engineers who also train other engineers in the same software.

What clients ask before a design job
Which design methods do you use?
LRFD, WSD or limit state design, chosen to suit the governing code and the owner's specification.
Which codes do you design to?
DNV-OS, ABS, NORSOK and ISO, as the project and the owner require.
Can you design modifications to an existing structure?
Yes. Recent examples include relocating a 150 MT safe-working-load SMIT bracket, a new ST-80 floor socket at the drill floor and a new compressor platform on a jack-up's main deck.
Do you cover load-out and transportation?
Yes. We run load-out and transportation analyses and design the sea-fastening for the tow.
What will we receive?
A calculation report with results and recommendations and, where the scope includes them, reinforcement details and detailed drawings.
Have a structure to design or modify?
Send us the drawings, the loads and the change you need. An engineer will come back with questions and a scope.
