Plant maintenance and turnaround services in Singapore

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.

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.

A five-decade process-plant specialist at 26 Gul Way serving the refining and petrochemical majors. Covers plant, term and turnaround maintenance — rotating and static equipment, furnace re-coiling and heat-exchanger hydrojetting; ASME-code pressure vessels, shell-and-tube exchangers, modules and pipe spools from workshops running automated spool output; API 650/620 storage-tank build and API 653 rehabilitation; and an E&I division for field instruments, DCS-panel and analyser-house work, calibration and loop checking.

A multi-disciplined turnaround specialist offering a blind-to-blind package: catalyst handling — load and unload with inert entry — mechanical decoking and pigging, heat-exchanger cleaning, tube-bundle and tubular services, reactor services, and rotating and mechanical maintenance. Its Singapore operation is at Jalan Buroh, part of the regional CR3 Group spanning Singapore, Thailand, Malaysia, India, Vietnam and Abu Dhabi.

The Singapore registered office of the global industrial-services group, delivering the full scaffolding-insulation-painting stack for turnarounds — insulation and cladding, access and scaffolding, surface protection and painting, passive fire protection and refractory — for oil, gas and petrochemical plants.

An industrial-services multinational (the former Cape, now under Altrad) providing access and scaffolding, insulation, coatings and specialist maintenance, with a long-standing Jurong Island presence supporting refinery and petrochemical turnarounds.

An international specialist in catalyst handling, mechanical decoking, industrial cleaning and rotating and mechanical services for refineries and petrochemical plants, active across Asia.

A Singapore contractor under the Actemium / VINCI Energies brand. Its chemical-cleaning and decontamination line delivers on-line and off-line chemical cleaning, degassing and decontamination, and heat-exchanger and vessel cleaning ahead of turnaround entry on refinery and petrochemical units; it also provides process-automation and control-systems integration for process and chemical plants, alongside mechanical, electrical and cleanroom design-build for life-science and precision-manufacturing clients.

A Singapore engineering firm on two lines that both trace to cleantec.com.sg: a turnkey cleanroom business — design, fabrication and distribution of cleanroom equipment for semiconductor, healthcare and life-science clients, NEBB-accredited and ISO 9001:2015 certified — and an industrial-cleaning line providing high-pressure hydrojetting, heat-exchanger and tube cleaning, and tank and vessel cleaning for plant maintenance and turnaround campaigns.

A local engineering contractor listed both among Singapore's cleanroom design-build providers and as a mechanical and plant-maintenance contractor supporting turnaround, shutdown and standing maintenance on process plant, piping and equipment for the energy and chemicals sector.

A SAC-SINGLAS ISO/IEC 17025-accredited calibration house covering 20-plus instrument categories — pressure, temperature, flow, electrical, dimensional, force and torque — with on-site mobile calibration and traceability, and a mechanical and rotating-equipment maintenance line supplying turnaround manpower, machining and equipment overhaul to Jurong Island process operators. Serves aerospace, petrochemical, electronics and energy.

A process-construction and maintenance firm specialising in the scaffolding-insulation-fireproofing-painting trades for Jurong Island oil, gas and refinery projects, with insulation the dominant share of its work.

An insulation and scaffolding-insulation-painting contractor serving oil refineries, petrochemical and gas plants, listed among the Singapore Chemical Industry Council's insulation contractors.

An industrial-services group — spanning AMS Resources, AMS Reliance and AMS Energy — providing maintenance and reliability services to the process sector.
