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 smartphone 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| 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 |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Singapore marine and shipyard sector: Paint and coating areas, Offshore unit conversion, Vessel tank and cargo spaces | Classified by the site operator |

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.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
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.
A distributor for Singapore marine and shipyard sector would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
