Ownership change
Seatrium describes itself as formed from the 2023 merger of Sembcorp Marine and Keppel Offshore & Marine, so older descriptions of Keppel-run yards are out of date.
Keppel's offshore and marine yards in Singapore are now part of Seatrium, formed in 2023 by the merger of Sembcorp Marine and Keppel Offshore & Marine. Repair, conversion and newbuild work on tanks, cargo spaces and paint areas creates Zone 1 conditions. An IECEx mobile phone distributor in Keppel Shipyard (now Seatrium yards), Singapore would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Keppel Shipyard (now Seatrium yards), Singapore 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Keppel Shipyard. 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 describes itself as formed from the 2023 merger of Sembcorp Marine and Keppel Offshore & Marine, so older descriptions of Keppel-run yards are out of date.
ST Engineering acquired the site and assets of the Gul yard formerly run by Keppel FELS in 2023: about 141,000 square metres, with three floating docks.
In 2015 Keppel Shipyard secured an FPSO conversion worth 89 million dollars covering repair, upgrade and modification, with completion expected in the third quarter of 2016.
Keppel privatised its offshore and marine business in 2001, and in 2002 combined Keppel Shipyard with Keppel FELS and Keppel Singmarine to form the Keppel Offshore and Marine group.
Seatrium, formed in 2023, groups its work into oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades.
Repair and upgrade scope at the Singapore yards covers gas carriers (LNG and LPG), floating production units, jack-ups and semi-submersibles, and jumboisation or dejumboisation, each with different tank and gas-freeing routines.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Keppel Shipyard (now Seatrium yards), Singapore. Ship owners, classification bodies and visiting contractors at the yards are international, so IECEx is a convenient reference for gas-free work on tanks and cargo spaces. The certificate of conformity and schedule of conditions would be reviewed. For the IS-04Z1 these remain targets, as certification is in progress.
A distributor for Keppel Shipyard (now Seatrium yards), Singapore 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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are vessel tank and cargo spaces, offshore unit conversion, paint and solvent areas, dry dock work. 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 Keppel Shipyard (now Seatrium yards), Singapore.
They typically arise in cargo and fuel tanks, pump rooms, voids and paint or coating areas while a vessel is being worked on. Classification changes with each job and with gas-free certification, so ask the yard safety team which spaces are zoned before carrying a portable device on board.
Access is normally arranged through the yard or the vessel owner's project team, with induction, a site pass and a hot-work or gas-free permit system. Addresses for each yard are listed publicly, but you need a named sponsor. Ask them for the equipment rules before shipping devices.
Shipyards control permits and gas-free certification per vessel, so approval can differ from job to job. Confirm device rules with the yard safety department, and expect to explain the marking, the certification status and how the device will be charged outside hazardous spaces.
