Western Islands, Singapore

The Western Islands Planning Area (Simplified Chinese: 西部群岛, Traditional Chinese: 西部群島, Pinyin: Xībù Qúndǎo, Malay: Kepulauan Barat, Tamil: மேற்குத் தீவுகள்) is located off the southwestern coast of Singapore within the West Region. Covering approximately 64.98 square kilometres, it is the largest planning area in Singapore by land size. The Western Islands are primarily industrial in nature and have no permanent residential population, being home instead to Singapore’s petrochemical and energy industries.

History of the Western Islands

In the past, the Western Islands consisted of a cluster of small fishing villages spread across numerous islets, including Pulau Ayer Chawan, Pulau Merlimau, and Pulau Pesek. Starting in the 1990s, massive land reclamation and island amalgamation projects consolidated many of these islets into the larger Jurong Island. This transformed the area into an integrated hub for the petrochemical industry, playing a central role in Singapore’s industrial and economic development.

Geography and Boundaries

The Western Islands are located off the southern and southwestern coast of mainland Singapore. The most prominent feature is Jurong Island, a man-made island formed through reclamation, which now houses dozens of global energy and chemical companies. Other islands in the planning area include Pulau Bukom, Pulau Busing, and Pulau Sebarok, which are home to oil refineries and storage facilities.

Economic and Industrial Significance

The Western Islands are the backbone of Singapore’s petrochemical and energy industries. Jurong Island alone hosts over 100 companies, including ExxonMobil, Shell, and Chevron. The island is part of Singapore’s “Jurong Island Version 2.0” initiative, aimed at enhancing energy efficiency, connectivity, and sustainability within the sector.

Pulau Bukom, operated primarily by Shell, is home to one of Singapore’s oldest oil refineries, dating back to the early 20th century. Pulau Sebarok, meanwhile, contains major oil storage facilities. The Western Islands also house infrastructure critical to Singapore’s energy security, including storage caverns for petroleum products.

Transport and Connectivity

The Western Islands are not accessible to the general public due to security restrictions. Access is strictly controlled and limited to workers in the industrial facilities. Jurong Island is connected to mainland Singapore via the Jurong Island Highway, but entry requires a security pass issued by the authorities.

Unlike other planning areas, the Western Islands are not served by MRT stations or public bus routes. Workers commute from nearby areas such as Jurong West, Pioneer, and Tuas.

Residential Aspect

There are no residential estates within the Western Islands. Workers commute daily from mainland Singapore, and accommodation is strictly prohibited within the planning area due to its industrial nature.
