Offshore wind and marine renewables in Singapore

Singapore's dominant marine and offshore group, formed from the merger of Keppel Offshore & Marine and Sembcorp Marine, operating the integrated Tuas mega-yard and legacy yards. It builds and integrates FPSO, FLNG and FPU topsides, jackets and offshore rigs, and a renewables book of wind-turbine installation vessels, floating wind and HVDC substations. Its graving docks run ship repair, drydocking and conversion at scale, with main-engine and machinery overhaul, propeller, tailshaft, rudder and sterntube work, and electrical, cabling and automation integration carried in-house.

An SGX-listed integrated marine-logistics group spanning shipyard, offshore energy and marine transportation, with newbuild and steel fabrication executed at its PT Marcopolo Shipyard in Batam and commercial, design and project management run from Singapore. It builds tugs, barges and offshore support vessels and has moved decisively into offshore wind — a multi-year CSOV framework with Siemens Gamesa (two CSOVs for Taiwan), a next-generation battery-hybrid CSOV Plus, and a high-spec research vessel.

An SGX-listed offshore-and-marine services contractor with two Singapore yards (Pandan Crescent and Penjuru Road, about 205 m combined waterfront). It provides EPCI support, marine construction and heavy steel fabrication, rig repair and drilling support, afloat and drydock ship repair, retrofitting and conversion, and offshore chartering — and self-builds locally-flagged crew-transfer vessels for offshore wind, including horizontal directional drilling for subsea-cable installation.

A publicly-listed Singapore designer-builder describing itself as the world's largest builder of IMO-registered aluminium commercial vessels. It designs and builds high-speed aluminium crew boats, security and patrol vessels, ferries and wind-farm craft under its proprietary Flex line, including pure-electric 200-passenger ferries and a full-hybrid crew boat, at Penguin Shipyard International (Tuas Road) and PT Kim Seah Shipyard, Batam.

A homegrown SGX-listed specialist in mooring systems and anchors, increasingly focused on floating offshore wind; secured a floating-wind anchor order in France and is quadrupling capacity via a roughly 98,919 sqm ex-Seatrium facility.

A homegrown PSA-group marine-services arm providing harbour towage and pilotage, offshore-wind crew transfer and inter-gateway feedering with a Singapore harbour-tug fleet.

A Singapore marine soil-investigation and geotechnical-testing firm supporting offshore-wind foundation design across ASEAN, with 1,000-plus marine boreholes reported.

A homegrown autonomous-underwater-vehicle developer providing subsea inspection at offshore wind farms.

A global dredging major and lead player in the Tuas Mega Port reclamation programme and the Pulau Tekong polder, operating large trailing-suction hopper dredgers; builds offshore-wind foundations, and its SMIT Salvage arm provides marine salvage and emergency response.

A dredging and marine contractor on the Tuas Mega Port expansion reclamation, operating large trailing-suction hopper dredgers and building offshore-wind foundations globally.

Runs subsea inspection, maintenance and repair (IMR), geophysical and geotechnical survey and ROV operations from a Singapore base serving Asia-Pacific oil-and-gas and offshore wind; commissioned a dedicated ROV test pool in Singapore to qualify vehicles before deployment.

A Singapore regional base delivering integrated survey, ROV, subsea installation and IMR from a fleet of high-spec offshore vessels; active in floating offshore wind (Hywind Tampen installation scopes).

A homegrown OSV owner with a large self-reported fleet — 21 anchor-handling tugs, 32 AHTS (DP-2), 22 PSVs plus MPSVs — serving oil-and-gas and renewables.

A homegrown Kuok-group OSV owner-operator running AHTS to 200-tonne bollard pull / 7,000 BHP, platform supply vessels, and DP3 semi-submersible and DP2 accommodation (walk-to-work) vessels among the world's largest; MPA-licensed for Singapore harbour towage, with subsea and offshore-wind support scope.

A Singapore entity providing marine warranty surveys (project cargo, offshore oil-and-gas, renewables, towage and rig-move approvals), 24/7 casualty response (salvage, wreck removal) and naval-architecture consultancy.
