Gul yard
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.
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. 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. An industrial 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.
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. 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.
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.
Seatrium lists Singapore yards at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard, with headquarters at 80 Tuas South Boulevard.
Pioneer Yard offers a 1,400 metre quay with 8 to 10 metres of depth, and Crescent Yard has a 740 metre quay with 6 metres of depth, supporting several vessels alongside at once.
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.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Keppel Shipyard (now Seatrium yards), Singapore. Repair and conversion projects bring many subcontractor crews, each employer with its own devices. Permit handling per vessel means device control matters. The IS-04Z1 runs Android 16 and is designed for EMM and MDM, so a yard or subcontractor could enrol, lock and reassign handsets, with charging outside the hazardous space.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Keppel Shipyard (now Seatrium yards), Singapore 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 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.
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.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
