Seatrium builds and converts offshore rigs, floating production units and ships, and repairs vessels, in yards that include Tuas Boulevard, Tuas, Benoi and Sembawang. This page is for the HSE, yard operations and IT teams who must decide what explosion proof mobile phone in Singapore may be carried onto a hull during gas trials, tank entry and hot work. 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
Seatrium was formed when Sembcorp Marine completed its acquisition of Keppel’s offshore and marine division in February 2023 and took the new name later that year. In Singapore it brings the former Keppel yards at Tuas Boulevard, Tuas and Benoi together with the Sembawang yard. A yard is not a classified plant. It becomes one, temporarily and in patches, when something flammable is on the hull. A tanker arrives for repair with cargo residue in its tanks and has to be gas-freed before anyone can weld. An FPSO conversion reaches hydrocarbon commissioning and then has live gas and oil systems in a quayside berth. Coating and painting inside tanks release solvent vapour. Each of these creates a Zone 1 or Zone 2 area that exists for a shift or a month and is then declared gone. The question for a handset is not whether the yard is classified, but whether the person carrying it can enter the space that is.
A yard moves. The job today is not where the job was last week, and the classified area follows the hull rather than the map.
Each job needs its own permit, and a gas-free certificate may expire at the end of a shift. A handset that stays with the person lets the permit, the test record and the photograph live together rather than on separate pieces of paper.
Hot decks, spray, dust and constant handling are normal. IP68 sealing and rugged build suit that, and the certificate states the temperature class and ambient range the marking holds for.
A yard is long and a ship is taller than it looks. A 4,000 mAh battery covers a full shift of walking, calls, photographs and position fixes without a trip back to a safe-area charger.
Yards run many contractor teams on one site. Android Enterprise enrolment from an existing MDM console lets Seatrium’s IT team issue handsets by job, limit the apps and withdraw them at handover.
How Seatrium assesses equipment suppliers is for its procurement and HSE teams to say. We do not claim any listing or relationship; send us their requirements and we will respond in writing.
A supervisor at a cargo tank hatch photographs the gas-test reading and the entry log, then reports status from the same device. The photograph is stamped with time and position.
When hydrocarbons are introduced at the quay, the commissioning team works in live classified areas. A handset that can sit in the pocket keeps the punch list and the call to the control room with the person.
A hot work fire watcher can record the area check and the photograph, and the permit officer sees it without walking across the yard.
Parts of it are, temporarily. Cargo tanks being gas-freed, hydrocarbon commissioning on a topsides module and solvent coating in a tank are all classified conditions. The phone is for those conditions, not for the offices.
No. A handset is not a gas detection instrument, and the permit and gas-free certificate still rely on the correct testing equipment. The phone carries the records, calls and photographs around it.
No. This page describes the conditions in the yards and what the device is designed for. It is not an endorsement or supply agreement.
Only that Sembcorp Marine completed its acquisition of Keppel’s offshore and marine division in 2023 and became Seatrium, which is how company announcements describe it.
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.
