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 lists Singapore yards at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard, with headquarters at 80 Tuas South Boulevard.
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from the 2023 merger of Sembcorp Marine and Keppel Offshore & Marine, so older descriptions of Keppel-run yards are out of date.
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.
Singapore has an equatorial climate with steady heat, high humidity and frequent afternoon rain, so outdoor yard work exposes handheld equipment to moisture and sun throughout the year.
Seatrium's Singapore yards include Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard, plus the offshore-focused Crescent and Pandan yards, so contractors may work at several sites in one project.
The yards are spread widely: Admiralty Yard is on Admiralty Road West in the north, while Benoi, Pioneer, Tuas and Tuas Boulevard yards sit in the industrial west of the island.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Keppel Shipyard (now Seatrium yards), Singapore. In a shipyard, explosion-proof is a loose label for tank, cargo space and paint-area work. Fixed equipment may be flameproof Ex d, while handhelds used inside tanks are more likely to rely on intrinsic safety. The IS-04Z1 is designed for intrinsic safety, so state the concept needed for each task.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Keppel Shipyard (now Seatrium yards), Singapore. 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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is 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.
