Offshore Engineering
Detailed design, structural analysis, strength assessment and certification of fixed and floating offshore structures, through every phase from load-out to life extension.
- 2700+documented jack-up rig projects
- 18+years in offshore engineering, since 2008
- 3regions: India, Middle East, North Sea
- 5+analysis tools: SACS, ANSYS, MOSES, MAXSURF, STAAD.Pro etc.
Four offshore engineering services
Each service has its own page with the scope, the methods and the projects behind it.
Design engineering and structural analysis
Structural analysis of fixed platforms, floating vessels and semi-submersibles, from pre-service and in-service checks to advanced analyses.
Life extension and certification
Strength assessment of ageing assets, modelling corrosion, operational damage and member deterioration, with strengthening designed where needed.
FEM analysis
Global models and detailed connections, with linear and non-linear responses under realistic loading, for upgrades and modifications.
Jack-up rig engineering
Rig conversions, leg length changes, helidecks, cranes, drill floor and deck modifications, sea-fastening and tow.

Offshore projects we have delivered
Bow leg brace damage study
Local strength and buckling of a bow leg with three damaged braces, and the reinforcement needed for safe operation.
Helideck upgrade for MI-17 operations
Structural analysis, reinforcement details and a complete drawing package so a jack-up could take the 13 t MI-17.
Cantilever and substructure securing for ocean tow
Structural response of the cantilever and substructure with a new securing arrangement for ocean tow.
The tools we analyse with, and teach
Your structure is analysed by engineers who also train other engineers in the same software.
Software

What offshore owners ask us
Can you assess an existing platform for life extension?
Yes. We model the structure with its corrosion and member damage, run global strength, pushover and fatigue checks, and design strengthening where it is needed so the asset can be certified fit for purpose.
Which analyses do you run for transport and installation?
Load-out, sea-fastening, transportation, lifting and installation analyses, including tow inertia loads, with fabrication drawings for sea fasteners where the scope requires them.
Which codes do you design to?
DNV-OS, ABS, NORSOK and ISO, using LRFD, WSD or limit state methods as the project requires.
Which software do you use?
SACS, ANSYS, MOSES, MAXSURF and STAAD.Pro. Aryatech is also an authorized Bentley partner and trains engineers in SACS, MOSES, MAXSURF and STAAD.Pro.
Do you work on jack-up rigs?
Yes. We have 16 documented jack-up projects, from helideck upgrades and leg damage studies to cantilever extensions and tow securing, in India, the Middle East and the North Sea.
Have an offshore structure to design, verify or extend?
Send us the drawings, the inspection data and what has changed. An engineer will come back with questions and a scope.
