Offshore modules & structures manufacturers and suppliers in Singapore

An SGX-listed offshore-and-marine services group on two divisions: Infrastructure Engineering — supply of pedestal cranes and deck equipment for offshore operations, with growing shipbuilding and deck-equipment work — and a long-established Corrosion Prevention and asset-integrity business (surface preparation and protective coatings) that operates as a resident contractor inside the major Singapore and Batam yards, serving the Seatrium, ST Engineering and PaxOcean groups. Focused on the FPSO/FSO market.

Singapore's leading independent topside-module fabricator and a multi-disciplinary EPC/EPFC contractor for FPSO and FLNG topside modules and integration, plus offshore facilities across hydrocarbon and petrochemical markets. It runs two Gul Road yards with combined land area over 140,000 m2, expanded via the Exterran Offshore yard to push waterfront past 680 m and add split-module construction, with growing hydrogen and ammonia piping work. SGX-listed.

A long-established process-plant EPC and fabrication contractor for oil, gas and petrochemical clients, based at Tuas with a regional Asia-Pacific presence. Provides plant maintenance, turnaround and shutdown services; fabricates pressure vessels, heat exchangers, process modules and gas compressors; and builds onshore tank farms, terminals and gas-metering facilities. Both an EPC contractor and a fabricator, with a track record on Jurong Island and regional LNG and petrochemical facilities.

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.

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 EPC and fabrication specialist in modular steel structures for oil, gas, power and marine, with standout capability in large electrical power buildings (E-Houses), pre-fabricated substations, power-generation and utility modules and blast- and fireproof structures. Its yard offers around 30,000 m2 open area, 210 m sea frontage and load-out of modules up to about 2,000 tonnes; it delivered the 1,560-tonne Kraken E-House for a North Sea FPSO.

An SGX-listed offshore-and-marine group. Its Offshore & Engineering arm fabricates and maintains structures — skids, filtration systems, pressure vessels and storage tanks — with rope-access services; its Marine arm is a long-established sterngear, propeller and CPP-blade reconditioning and bronze-casting specialist, covering propeller-shaft work and dynamic balancing in-house and on-site at shipyards, anchorages and onboard; and an Energy Services arm handles tank de-sludging and hydro-cleaning.

An SGX-listed plant-and-terminal engineering contractor and one of Singapore's largest, combining project works (EPC) with integrated turnaround and standing maintenance for refineries, petrochemical plants and bulk-liquid terminals on Jurong Island and across the Gulf. Scope spans ASME-stamped pressure-vessel and piping fabrication, static and rotating equipment, storage-tank and terminal services, and electrical and instrumentation; peak turnaround mobilisation runs into the thousands of workers. Its module-fabrication arm also serves offshore markets.

A long-established Jurong Island EPC and plant-services group (privatised in 2021) whose core strength is turnkey onshore plant and terminal EPC — tank farms and refineries. Delivers integrated maintenance, shutdown and turnaround; operates its own fabrication yards for pressure vessels, pipe spools and structural steel to ASME code stamps; builds storage tankage; and, through Rotary Electrical & Instrumentation, provides field instruments, gas and fire detection, SCADA/PLC, analyser integration and in-house calibration labs.

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.

The marine arm of ST Engineering, one of the region's largest shipbuilders and ship-repair and conversion houses, operating the Benoi and Tuas/Jurong yards with in-house design. It builds naval vessels — patrol, littoral-mission and landing craft and frigate-class combatants — and commercial RoRo, tankers and ferries, and provides repair, refit, modernisation and conversion across both fleets. Engine-room and machinery work, propulsion, sterngear and steering-gear, deck-equipment fit-out and shipboard combat, navigation and platform-management electronics are carried in-house.
