Our Capabilities

What We Deliver

Our structural engineers deliver certified engineering packages for offshore lifting operations, subsea structure installation and seafastening design, from preliminary analysis to Issue for Approval documentation accepted by certifying authorities.

FEA Analysis (Finite Element Analysis)
Static, dynamic and fatigue analysis using ANSYS Mechanical, SACS and StaadPro. Delivered with full calculation report.
Seafastening Design
Cargo and equipment seafastening packages for heavy marine transport, compliant with DNV-ST-N001 and project-specific motion criteria.
Lifting & Rigging Engineering
Offshore and onshore lift studies, rigging design, padeye calculations and load-out engineering to DNV-ST-N001 and DNV-ST-0378.
Subsea Structure Design
Manifold support frames, protection structures, mudmats and pile anchors, designed to API RP 2A, ISO 19902 and project codes.
Offshore Platform Structures
Topside structural assessments, jacket modification engineering and jacket installation aids.
Fabrication Drawing Packages
Full IFR/IFA/AFC structural drawing packages, bill of materials and weld procedures coordination.
