Sector 01
Offshore Oil & Gas
The backbone of our practice — full-field engineering for operators and EPCs, from wellhead to export. New platform developments, brownfield tie-ins, requalification, and owner's engineering on live assets across the offshore oil and gas value chain.
Capabilities
New Developments
- Concept, FEED and detailed design — fixed jacket platforms, concept through installed asset
- Topsides module structural design — FEED to fabrication, module support frames
- Pile and foundation design — axial, lateral, soil-structure interaction, API RP 2GEO
- Pipeline and riser tie-in — wellhead to export, code-compliant design
Brownfield & Life Extension
- Brownfield tie-ins — modifications and load-increase studies on live platforms
- Structural requalification — API RP 2A Sec.17 / ISO 19902 Annex A
- Fatigue re-assessment and pushover / RSR — remaining life, life-extension justification
- Platform modification engineering — conductor additions, deck extensions, appurtenances
Owner's Engineering & T&I
- Owner's engineering — bid evaluation, technical contractor oversight
- Offshore site supervision — installation engineering and field support
- Marine Warranty Survey (MWS) — package preparation and approval
- Transportation, jacket launch and offshore lift — MOSES and SACS-based analysis
