The most concentrated capital in Singapore
Jurong Island is the single most concentrated piece of industrial capital in Singapore, and in 2025 it spent the year proving both its resilience and its fragility. Built by stitching seven offshore islands into one landmass of around 3,000 hectares, it houses more than 100 global energy and chemicals companies, over S$60bn of cumulative investment and roughly 27,000 workers. The sector it anchors accounts for around 3% of Singapore’s GDP and about a quarter of manufacturing output. Yet the chemicals cluster grew just 0.2% in value-added terms in 2025, feedstock economics are tightening into 2026, and the island’s largest historical operator, Shell, has walked away.
What Jurong Island actually is
Jurong Island is engineered ground: between the mid-1990s and 2009 Singapore reclaimed and merged seven islands off its south-western coast into a single industrial estate managed by JTC Corporation. The island marked its 25th anniversary in 2025, having grown to around 3,000 hectares laced with more than 100km of shared pipelines.
That shared infrastructure is the point. Rather than each plant building its own jetties, storage, utilities and pipe racks, tenants plug into common corridors that move feedstock and intermediates from one facility to the next — a naphtha stream leaving a refinery can arrive as a cracker input next door without touching a road. This plug-and-play integration, backed by deep-water berths and third-party logistics operators such as Vopak, is what lets a land- and resource-scarce city-state compete with the petrochemical giants of the Gulf and the US Gulf Coast. Singapore has no oil of its own; it imports crude, adds value, and re-exports fuels and chemicals.
The reason short pipes matter is the chemistry itself. A refinery cracks crude into fuels and feedstock; a steam cracker turns naphtha into ethylene, propylene and butadiene; downstream plants turn those into polymers, solvents, elastomers and specialty chemicals. Every one of those handoffs is cheaper, safer and less carbon-intensive over a pipe than over a road or a jetty. Cluster the plants and the handoffs almost disappear — an advantage no individual operator could build for itself.
The scale, and the majors that built it
The headline numbers are substantial. ExxonMobil runs one of its largest integrated manufacturing sites in the world here, centred on a refinery of about 592,000 barrels a day fused with a petrochemical complex — and it is still investing, firing up new lubricant and higher-value fuel units at the Singapore complex in September 2025. The tenant roll reads like a directory of global chemistry: BASF, Chevron Oronite, Mitsui Chemicals, Sumitomo Chemical, Lanxess, Evonik, Chevron Phillips and dozens of specialty players. Since 2021 alone, more than 30 specialty-chemicals projects have been committed, expected to create over 1,000 jobs — a deliberate tilt from bulk commodity output toward higher-margin products.
The economic weight is real but should be read precisely. Energy and chemicals contribute around 3% of GDP directly; the more telling figure is that the sector represented roughly a quarter of Singapore’s manufacturing output, making it one of the pillars that keep manufacturing near a fifth of the economy. Employment of more than 27,000 is modest in headcount but high in value per worker, reflecting the capital intensity of refining and cracking.
Two further operators anchor the crude and feedstock end. Singapore Refining Company processes 290,000 barrels a day at Pulau Merbau. Petrochemical Corporation of Singapore, the island’s first petrochemical complex, runs two naphtha crackers and supplies ethylene, propylene and butadiene into the plants around it. Downstream sit world-scale single-product plants — methyl methacrylate monomer, phenol and acetone, butyl rubber for tyre inner liners, solution styrene-butadiene rubber, polyolefins, vinyl acetate-ethylene emulsions — most owned by different companies, many feeding each other.
The utilities are an industry of their own
A cracker is useless without industrial gases, steam, power and water at scale and without interruption. Air Liquide runs six air-separation plants on the island connected by more than 200 kilometres of pipeline; Linde operates one of Asia’s largest integrated hydrogen and carbon-monoxide facilities alongside its own air separation. Storage and logistics form a third layer: independent tank terminals hold crude, products and chemicals for owners who never build a plant, and the jetties connect the whole thing to the world’s largest bunkering port a short distance away.
The Shell exit — and what it signals
The defining corporate event was Shell’s departure. On 1 April 2025, Shell completed the sale of its Pulau Bukom refinery and its Jurong Island petrochemical assets — collectively the Singapore Energy and Chemicals Park — to CAPGC, a joint venture between Indonesia’s Chandra Asri and commodities trader Glencore. Shell had refined oil at Bukom since 1961; the site was the company’s oldest refinery and the birthplace of its Asian downstream business. Its exit closed a 64-year chapter.
Read carefully, the sale signals two things at once. First, the majors are rationalising — Western integrated oil companies are shedding older, sub-scale refining and cracking assets in Asia to concentrate capital on chemicals megaprojects, low-carbon lines and upstream returns. Second, the assets themselves remain wanted: a Jakarta-listed petrochemical producer and a global trader paid to own crude-processing and cracking capacity at the heart of the world’s busiest bunkering port. The plant did not close; it changed hands. For Jurong Island the distinction matters enormously — the record shows continuity of operation under new owners, not abandonment. The pressure is on margins, not on the island’s existence.
That pressure is genuine. The chemicals cluster was essentially flat in 2025, growing 0.2% in value-added terms, squeezed by weak regional demand and by feedstock costs that leave Asian naphtha crackers structurally disadvantaged against US ethane and Middle Eastern gas. Into 2026 the feedstock pinch persists, and older assets face the classic Asian refining question: reinvest and decarbonise, or run down.
The energy transition on reclaimed land
Jurong Island’s answer is to change what it makes. The estate is being repositioned under a “Sustainable Jurong Island” plan built around low-carbon fuels, carbon capture and cleaner chemistry.
The most advanced example is Neste’s renewables refinery. Following its Tuas expansion, Neste operates a facility capable of producing about 2.6 million tonnes a year of renewable products — renewable diesel and feedstocks — including capacity for up to roughly 1 million tonnes of sustainable aviation fuel (SAF). That makes Singapore one of the largest SAF production hubs in the world, with a supply chain running directly to Changi Airport. As aviation faces mandated SAF blending through the 2030s, this is the clearest case of Jurong Island manufacturing its way into the transition rather than being displaced by it.
Carbon capture is the second lever. The Sustainable Jurong Island plan targets at least 2 million tonnes a year of carbon capture by 2030, and industry-led studies have explored aggregation and cross-border storage. Alongside this sit hydrogen and ammonia ambitions as future low-carbon fuels and feedstocks, and a deliberate land strategy: close to 300 hectares — roughly a tenth of the island — has been set aside for new energy solutions. None of this is guaranteed: carbon capture at commercial scale remains costly, cross-border CO₂ storage depends on regional partners, and green-hydrogen economics are unproven. But the direction is set by policy and capital, not aspiration alone.
The industrial supply chain beneath the majors
Behind every refinery and cracker is a supply chain that rarely makes headlines but determines whether plants run safely and on time — and it is where much of Singapore’s home-grown industrial base earns its living. A 592,000-barrel-a-day refinery is, mechanically, tens of thousands of valves, hundreds of pumps and compressors, kilometres of piping, banks of pressure vessels and heat exchangers, and storage tanks measured in the hundreds of thousands of cubic metres.
That translates into steady demand for industrial valves (gate, globe, ball, butterfly, control and safety-relief valves rated for high pressure and corrosive service); pumps and rotating equipment (API-standard centrifugal and positive-displacement pumps, and the seal and vibration-monitoring services that keep them turning); pressure vessels, columns and heat exchangers fabricated and code-stamped to ASME standards; piping, fittings and tank fabrication; and plant maintenance and turnarounds — the periodic shutdowns in which a plant is inspected, repaired and recertified, mobilising thousands of contract workers over a few intense weeks. This ecosystem is the quiet majority of the energy and chemicals workforce and the part of the record most relevant to Singapore’s small and mid-sized industrial suppliers.
The turnaround trades are specialisms in their own right: catalyst handling with inert entry, mechanical decoking, heat-exchanger cleaning, scaffolding and insulation, and rotating-equipment overhaul. Several of Singapore’s largest engineering contractors exist substantially because Jurong Island exists. Described only as a refining cluster, the island is undercounted by an entire industry.
Outlook
The honest verdict is mixed. Jurong Island enters 2026 with a flat chemicals cluster, structural feedstock disadvantage against gas-rich rivals, and the symbolic loss of its founding refiner. Those are real headwinds. Set against them: the assets keep running under new owners, ExxonMobil is still investing in higher-value units, Neste has made Singapore a global SAF centre, and the state has committed land, grants and a carbon-capture target to reposition the island for the transition. The strategy is not to out-produce the Gulf on commodity ethylene — Singapore cannot — but to move up the value chain into specialties, low-carbon fuels and integrated services, and to keep the shared-infrastructure advantage that no single plant could build alone. Over S$60bn is already in the ground. The more probable path is managed transition: fewer commodity barrels, more sustainable tonnes, and a supply chain that has to master new chemistry to stay employed.
