Jurong Island, Singapore

Jurong Island, located off the southwest coast of Singapore, is regarded as a prime example of an integrated port-industrial development. Today it functions as the core of Singapore’s petrochemical and energy sector, but its current form is the result of a deliberate, long-term strategy that transformed a cluster of small offshore islands into a single, consolidated industrial platform.

Prior to its consolidation, the area consisted of multiple separate islands such as Pulau Ayer Chawan, Pulau Merlimau, and Pulau Pesek. These islands underwent early industrialization in the 1970s, when major oil companies established individual refineries on separate islands (for example, Esso on Pulau Ayer Chawan, and the Singapore Refining Company on Pulau Merlimau). While this development leveraged available coastal land, it is understood resulted in a fragmented industrial layout, with duplicated infrastructure and limited integration between facilities.

By the 1990s, increasing demand for industrial land and the need to strengthen Singapore’s petrochemical sector prompted a strategic shift toward greater integration and efficiency. The government chose to build on this already modified industrial landscape by amalgamating the offshore islands through reclamation works. Between 1995 and 2009, the islands were progressively joined to form a single, contiguous landmass, creating a single landmass of about 3,000 hectares (JTC, 2025).

This transformation enabled the creation of a highly integrated petrochemical cluster on an expanded, masterplanned land base. By consolidating islands that had already supported industrial activity, the approach built on existing developed areas, although it still required large-scale reclamation. The site’s location within Singapore’s southern waters also provides relatively sheltered marine conditions that support reliable port operations.

Equally important is the island’s highly optimized spatial planning. The unified landmass enabled Singapore to develop a tightly integrated industrial ecosystem, where refineries, storage terminals, chemical plants, and marine facilities are co-located and connected through shared infrastructure such as pipelines and utilities. This clustering approach reduces duplication, improves land-use efficiency, and enables more efficient material flows across the site. The masterplanned layout also supports logical phasing and future ‘just in time’ expansion, allowing additional development without significant reconfiguration or repeated disturbance.

Jurong Island demonstrates how the strategic consolidation of existing industrial sites can deliver both operational and land-use efficiencies. By transforming a dispersed set of refinery locations into a single, coordinated industrial platform, it provides a strong example of how site selection and spatial planning can be aligned to support long-term development, efficiency, and resilience.
