Ownership
Shell sold the Bukom refinery and Jurong Island chemical units to CAPGC, a Chandra Asri and Glencore joint venture, on 1 April 2025; the site now trades under the Aster name.

Industrial Mobile Phone in Pulau Bukom Refinery
Pulau Bukom is a restricted-access island about 5 km south of mainland Singapore, home to a 237,000 barrel-per-day refinery and an ethylene cracker. Since April 2025 the complex has been owned by CAPGC and operated as the Aster Energy and Chemicals Park, so process units create Zone 1 areas. If you are specifying an industrial mobile phone for Pulau Bukom, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

What Pulau Bukom means for portable equipment
Island access
Access is restricted to personnel with security passes, and staff travel by ferry, so equipment is usually checked before the crossing.
Field notes · Pulau Bukom
More about Pulau Bukom that matters for portable equipment
Pulau Bukom: climate and equipment wear
Singapore's equatorial climate gives consistent heat and humidity with frequent heavy showers, which affects open-air process plant, tank farms and jetties year round.
Pulau Bukom: logistics and access
Security passes are issued only to personnel working on the island, and a ferry from the Pasir Panjang ferry terminal, run by Tian San Shipping, serves it, so visitor transfers must be arranged in advance.
Pulau Bukom: geography and layout
Pulau Bukom is a restricted-access island of about 145 hectares, roughly 5 km south of mainland Singapore in the Singapore Strait, with a small companion islet to its south.
Pulau Bukom: industry on the ground
Singapore's energy and chemicals sector is its second-largest manufacturing sector, so the island's refinery and cracker sit within a national cluster of more than 100 chemicals companies.
The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Pulau Bukom. Contractors may move between Bukom and the linked chemical units on Jurong Island, so a managed fleet needs consistent EMM or MDM enrolment on both sides. Devices are usually checked before the ferry crossing, which makes pre-enrolment sensible. Charging should happen in a safe area, never inside a classified zone, and the operator sets the network rules.

- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.

Questions · Pulau Bukom Refinery
Frequently asked questions
Can we buy an industrial mobile phone in Pulau Bukom Refinery today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an industrial mobile phone in Pulau Bukom Refinery cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Which areas at Pulau Bukom would use it?
Likely candidates are refinery process units, ethylene cracker, crude and product tank farms, jetties. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Is the Bukom site connected to Jurong Island?
Yes. A 5 km subsea pipeline links Aster Bukom to Aster's chemical complex on Jurong Island, so the two sites run as one integrated operation. Expect shared safety standards between sites, but confirm site-specific rules with each location.
What process areas are on Bukom?
Aster describes Bukom as a fully integrated site focused on refining and ethylene production. That means crude units, cracker furnaces, tank farms and jetties, where Zone 1 and Zone 2 gas areas are typical. Exact zoning is set by the operator's area classification.
How does island access affect bringing handhelds to Bukom?
The site restricts access to personnel with security passes, and staff travel by ferry, so equipment is usually checked before the crossing. Ask the operator's security and HSE teams what device checks apply, and plan enrolment and charging before travel. Confirm the current process with the site operator.
