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. Tuas Port, opened in September 2022, is planned to handle 65 million TEU a year in the 2040s, moving more container traffic to the western end of the island. An ATEX and IECEx 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

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.

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 Singapore ship repair yards are Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard, with offshore-specific Crescent and Pandan yards in addition.
Seatrium organises its business into oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades, all based around Singapore.
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.
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.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Singapore marine and shipyard sector. Ship repair and conversion work draws vessel owners, classification surveyors and yard crews from many countries, so a reviewer would look for ATEX and IECEx evidence for any handheld used in tanks. The IS-04Z1 certification is in progress and only a datasheet is available now. The yard or vessel owner decides what it accepts.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Singapore marine and shipyard sector 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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
