Aster Chemicals and Energy operates the integrated refining and chemicals complex on Pulau Bukom and Jurong Island, where the island refinery, the cracker and the oxide, glycol and polyol units sit across two sites joined by pipeline and by boat. This page is for the HSE, operations and telecoms teams who must decide what explosion proof mobile phone in Singapore may be carried across that split. The IS-04Z1 is pre-launch and no certificate has been issued. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
The complex was long run by Shell, and press reports say the sale to a joint venture led by Chandra Asri with Glencore completed in April 2025, with the operating business now called Aster Chemicals and Energy. For the people on the plant none of that changes the geography. Pulau Bukom carries the refinery, tankage and jetties and is reached by launch from the mainland. Jurong Island carries the chemicals side, including the cracker and the units on Seraya and Merbau that make ethylene oxide, glycol, polyols and styrene. The two are tied by pipelines under the sea, so a feed problem on one island shows up as a work order on the other. That makes this one of the few Singapore complexes where a handset has to be useful at both ends of a boat trip. The mix of hazards is equally broad: refinery hydrocarbons, hydrogen at treating and cracking, ethylene oxide in the oxide train, and powder in the polymer and additive handling.
The boat is the point. Almost everything that is awkward about equipment at this complex comes from the fact that the device you left on the other island is not a short walk away.
A crew crossing to Bukom takes what it needs for the shift. A single device that does the call, the photograph, the position fix and the permit lookup means fewer items to forget, and fewer trips back to collect them.
A 4,000 mAh battery is specified to last a whole round with the radio, camera and GNSS in use. Charging stays in the safe area at the jetty or the control building.
Spray, rain and wet deck are routine at the jetties. IP68 sealing and rugged build suit that, and the certificate states the ambient range that the marking is valid for.
Reporting a leak on a tank farm or along a pipe rack by position rather than description helps when the visible landmarks are all tanks that look alike. The 50 MP camera attaches the photograph.
Aster’s own procurement and HSE teams decide what an equipment supplier must show before a device enters a unit. We have not been through any such process and do not claim a listing; ask them for their requirements and we will answer against them.
An operator on a tank farm round records levels and photographs a valve line-up, with a position stamp, and sends it before reaching the shore. The round sheet and the camera become one device.
A turnaround crew crossing by boat carries a managed handset enrolled for the job, with the permit list and site contacts loaded. At the end of the campaign the console wipes it.
In a unit with a flammable and toxic hazard together, a process technician needs to report a finding without handing a device to anyone outside the area. A handset that stays in the pocket keeps the report at the point of work.
No. It describes the conditions on the complex and what the device is designed for. There is no pilot, agreement or customer relationship with Aster, and certification is in progress ahead of the Q4 2026 launch.
No. Ethylene oxide is a group IIB gas. Hydrogen and acetylene are the IIC gases that matter on this kind of complex, so the marking target is IIC to cover all of them with one device.
The Ex marking is not tied to an island, but each unit has its own area classification and permit system. The device suits a fleet that travels, and the site decides which areas it is accepted in.
A certified handset cannot be opened by a general repair shop without invalidating the certificate. Service is planned to run through SAMS and a Singapore partner, and the arrangement is still being defined.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Singapore. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
