Field notes · Jurong Island
More about Jurong Island that matters for portable equipment
Jurong Island: who works there
Aster's Bukom refinery and its Jurong Island chemical complex are linked by a 5 km subsea pipeline, so products and feedstocks move between the two islands without ship transfers.
Jurong Island: infrastructure
Jurong Rock Caverns, completed in 2014, were the first commercial underground liquid-hydrocarbon storage in Southeast Asia, sited under the seabed of Banyan Basin about 120 metres (390 feet) below sea level.
Jurong Island: geography and layout
The island was created by reclaiming and amalgamating seven southern offshore islands, and its land area was tripled from the original 1,000 hectares, as described by the Prime Minister at the caverns' opening in 2014.
Jurong Island: people and language
The nearest rail link is Lakeside MRT station; public bus 98 runs to the Jurong Island Checkpoint, and some plants run private shuttle buses between the checkpoint and their premises.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Jurong Island. Classified areas on Jurong Island include refinery and cracker process units, chemical and petrochemical plants, LNG storage and loading, underground rock cavern storage and marine jetties. Each operator classifies its own areas, not JTC and not SAMS. Obtain the drawings from the plant before choosing equipment.
The route · distribution
Distributing the IS-04Z1 in Jurong Island
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Jurong Island yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Jurong Island.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Jurong Island
Frequently asked questions
Can we buy a hazardous area mobile phone in Jurong Island 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 a hazardous area mobile phone in Jurong Island cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Which areas at Jurong Island would use it?
Likely candidates are refinery and cracker process units, chemical and petrochemical plants, lng storage and loading, underground rock cavern storage. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Jurong Island?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Jurong Island.
Are the underground storage caverns a hazardous area?
The caverns store crude oil, condensate, naphtha and gasoil, so hydrocarbon vapour hazards are expected around the facility's surface operations. The actual zone boundaries are set by the operator's area classification drawings, so confirm them before taking any portable device near the site.
How do visitors get onto Jurong Island?
Visitors typically apply for a Jurong Island visitor pass at the island checkpoint, exchanging an identity card or passport, and then collect a separate security pass at the plant. Each plant sets its own induction, escort and screening steps, so book the visit through a named sponsor.
Does underground rock cavern storage change the requirement?
Jurong Rock Caverns hold crude oil and petrochemical products below ground, adding confined-space and below-ground classified areas. The plant sets the classification and entry rules. Ask the operator which zone applies and whether handhelds are permitted, and check that the marking suits that zone.
