Offshore & Marine Engineering Support for Nigeria and West Africa

Engineering support for vessel owners, installation contractors and terminal developers in Nigeria, Ghana, Angola and the wider Gulf of Guinea: vessel upgrades and deck-equipment installation, pipe-lay and installation engineering, class approval packages and design review. Our team has delivered a pipe-lay vessel piggyback pipeline upgrade and a four-davit installation on vessels operating in Nigeria.

How the work is contracted

Nigerian content rules (NOGICD Act, NCDMB) and the NipeX joint qualification system mean operator tenders are held by Nigerian-registered companies. We work for those companies and for the international vessel owners and contractors serving them — as the engineering subcontractor or the owner’s engineer — and for project developers in Ghana, Angola and Mozambique whose engineering is procured internationally. Where a Nigerian tender requires it we team with an indigenous engineering partner.

Regulators, class and codes

Vessels are classed with ABS, DNV, LR or BV; installation and marine operations follow DNV-ST-N001 under a marine warranty surveyor; fixed structures and pipelines to API RP 2A, ISO 19902 and DNV-ST-F101. NCDMB and the Nigerian Upstream Petroleum Regulatory Commission govern content and approvals on the Nigerian side.

How we deliver

We deliver from Mumbai with the whole team in one office, which keeps the engineering consistent and the rates at Indian engineering-hour levels. Working hours in India Standard Time (UTC+5:30) overlap the Gulf for the full day, Europe for the afternoon and Southeast Asia for the morning, so review calls, class correspondence and comment resolution happen the same day. Site supervision and surveys are delivered by our engineers travelling to the yard or offshore location.

Projects delivered here

Pipelay vessel upgrade — piggyback pipeline installationTwo-phase engineering to modify an operating pipelay vessel for piggyback pipeline installation — from technical feasibility and modification concept to detailed engineering.Davit installation — 4 × 50 MT davitsStructural engineering for the installation of four 50 MT davits along the port side of an offshore construction vessel.

Services we deliver here

OSV & Vessel Conversion EngineeringConversion engineering for offshore support and work vessels: OSV to well-stimulation vessel, barge to pipe-lay barge, tanker to FSO/FPSO and LNG carrier to FSRU. We deliver the feasibility study, the structural, stability and systems engineering and the class approval package, as on a 200-tonne-steel OSV-to-WSV conversion completed in Norway in 2024.Lifting & Heavy-Lift EngineeringLift engineering for offshore and yard lifts: rigging design, lift-point and padeye checks, dynamic amplification, crane-vessel and barge stability during the lift, and the lift plan calculations reviewed by class or a marine warranty surveyor. Our team has engineered 100+ heavy lifts, including riser and conductor installation campaigns on ONGC platforms.Class Approval Drawings & Statutory DocumentationClass approval drawings, calculations and statutory documents for newbuilds, conversions and modifications, prepared to the rules of ABS, DNV, LR, BV, IRS, NK, KR, BKI, RINA and CCS and taken through plan approval on the owner’s or yard’s behalf. Founder experience as an IRS surveyor means the package is written the way the reviewer reads it.Sea Fastening & Load-out EngineeringSea-fastening and load-out engineering for cargo, modules and cranes carried on barges and heavy-transport vessels: motion and acceleration criteria, grillage and tie-down design, ballast and load-out sequences, and the calculation package prepared for marine warranty surveyor approval. Delivered from Mumbai to EPC, T&I and fabrication contractors in India, the Gulf, West Africa and Southeast Asia.FSRU & LNG Terminal Engineering with Cryogenic PipingEngineering for FSRU conversions and LNG import terminals: regasification and hull interface structure, jetty berthing and mooring analysis, cryogenic piping design and stress analysis to ASME B31.3, and class and IGC Code compliance. Cryogenic piping is a capability few boutique consultancies hold, and it lets us take an FSRU or terminal scope from marine structure to the regas manifold.

Frequently asked questions

Can you bid directly on Nigerian operator tenders?

Operator tenders under the NOGICD Act are held by Nigerian-registered companies. We work as the engineering subcontractor or owner’s engineer for those companies and for international vessel owners, and team with an indigenous partner where a tender requires it.

What have you delivered in Nigeria?

A pipe-lay vessel upgrade for piggyback pipeline installation and the structural engineering for four 50-tonne davit installations on a vessel operating in Nigerian waters.
