Seatrium cites around 60 years of design and construction of rigs, floaters, offshore platforms and specialised vessels, plus repair, upgrading and conversion of ship types.
Singapore's marine sector centres on ship repair, conversion and offshore yards, led by Seatrium, formed in 2023 from Sembcorp Marine and Keppel Offshore & Marine. Singapore sold 56.775 million tonnes of marine fuel in 2025, the largest bunkering volume of any port, so tanker, barge and fuel-transfer operations are a daily feature of its waters. An intrinsically safe mobile phone distributor in Singapore marine and shipyard sector would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Singapore marine and shipyard sector has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Singapore Marine. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Seatrium cites around 60 years of design and construction of rigs, floaters, offshore platforms and specialised vessels, plus repair, upgrading and conversion of ship types.
Seatrium's Singapore yards are listed at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard; ST Engineering operates the Gul and Benoi yards.
Seatrium's Tuas Boulevard Yard has a graving dock about 350 metres long and 66 metres wide, which can take very large tankers and floating production units.
Workplace safety in yards and on vessels falls under MOM's Workplace Safety and Health framework, and marine bunkering facilities are named among Singapore's common explosive-atmosphere locations.
Heat, humidity and heavy showers are constant, so shipyard crews and handheld devices face both corrosion and moisture ingress year round.
Repair scope includes LNG and LPG carriers, cruise ships and ferries, floating production vessels, jack-ups, tankers, container ships and heavy-lift vessels, as well as jumboisation work.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Singapore marine and shipyard sector. Tank entry, repair and conversion work means climbing through confined spaces with little room for a second device. A handheld intrinsically safe phone is intended to let a surveyor or supervisor record photographs and readings in those spaces. This depends on certification being completed and on the yard's permit rules.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Singapore marine and shipyard sector. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are vessel tank and cargo spaces, repair and conversion work, paint and coating areas, offshore unit conversion. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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 Singapore marine and shipyard sector.
Fuel transfer between barges and ships can create temporary vapour zones around connections and vents, depending on the fuel. Port and operator procedures control ignition sources during transfer. Ask the barge operator or ship's officer what equipment may be used on deck.
Seatrium lists LNG and LPG carriers and floating production vessels among the vessels it repairs and converts at its Singapore yards. These ship types generally bring the strictest hazardous-area controls, so confirm yard and vessel rules with the project team.
No. Yards and vessel owners set their own device rules, and the yard list here is not exhaustive. A device accepted at one yard may still need separate agreement at another. Confirm requirements with the yard safety team where the work will happen.
