Construction Design Engineering

Loadout
We provide design engineering services for safe and efficient module loadouts:

• Trailer Loadout: Loadout Support Frame (LSF) design
• Skid Loadout: Deck Support Frame (DSF) design
• Module structure integrity & stability check
• Skidway and jetty verification.

Fabrication

• Site Operations: Site Moving, lifting, temporary support design, fabrication sequence planning.
• Shop Drawings: Develop 3D model from 2D drawings, assembly drawings, cutting plan (including weld map), export of fabrication data to PMS software.

Our team applies proven offshore structural engineering experience to deliver practical solutions tailored to each project’s requirements.

OFFSHORE T&I DESIGN ENGINEERING

We deliver offshore transportation and installation (T&I) engineering services with extensive experience working alongside leading contractors such as Heerema, McDermott, and Saipem. Our scope covers:

• Grillage & Seafastening Design, including quick-release solutions for WTG foundations.
• Barge Global and Local Strength Checks to ensure safe load distribution.
• Rigging Platform Design for heavy lifts and offshore operations.
• Offshore Installation Aids Design to support complex site activities.
• Engineering Analyses: transportation, lifting, launching, pile driveability, and on-bottom stability.

SECONDARY STEEL DESIGN

We deliver secondary steel design services for Oil & Gas and Offshore Wind projects, focusing on practical, safe, and buildable solutions. Our work covers a wide range of structures, from topside modules to offshore wind turbine platforms and installation aids.

Capabilities:

• Topside Modules: Access platforms, equipment supports, pipe supports, pipe racks
• WTG: Internal and external access platforms
• Offshore Structures: Boat landings, riser intruder frames, grouting systems, mudmats

PRIMARY STEEL DESIGN

Our core team has extensive experience from nearly 80 offshore projects, delivering safe and reliable structural solutions. We provide design engineering for:

• Structural Modules: FSO/FPSO topside modules, TLP topside module, topside equipment skids, subsea manifolds, SSIV structures
• Topside, Jacket & Pile Structures: Wellhead platforms, Central Processing Platforms (CPP), offshore substations (OSS)

We combine practical offshore knowledge with proven engineering methods to ensure robust, buildable, and cost-effective designs.

SPECIAL DESIGN ENGINEERING SERVICES

Finite Element Analysis:

• Topside & jacket critical joints detailed analysis: stress, strain and buckling checks.
• Hot-spot stress fatigue check as per DNV-ST-0126
• Grouted connection design as per DNV-ST-0126 & DNV-RP-0419
