Yard locations
Seatrium's Singapore yards are listed at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard; ST Engineering operates the Gul and Benoi yards.
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. Tank work, repair and conversion create Zone 1 conditions on vessels. If you are specifying a rugged smartphone for Singapore marine and shipyard sector, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Singapore marine and shipyard sector: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Singapore marine and shipyard sector: Vessel tank and cargo spaces, Repair and conversion work, Paint and coating areas | 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's Singapore yards are listed at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard; ST Engineering operates the Gul and Benoi yards.
Seatrium describes itself as formed from the 2023 merger of Sembcorp Marine and Keppel Offshore & Marine, so older references to separate yards under those names are out of date.
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.
Seatrium's Singapore ship repair yards are Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard, with offshore-specific Crescent and Pandan yards in addition.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Singapore marine and shipyard sector. Shipyards combine sun, heat, tropical rain and salt air with grit from grinding and blasting. IP68 water and dust sealing is designed in for the IS-04Z1 and suits such wear. It is not explosion protection, which only comes from the Ex certification currently in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are 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.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Zones move with the vessel's cargo, tank status and gas-free certification, so a space may be classified one day and safe the next. Always check the vessel's permit and gas-freeing status rather than relying on a fixed plan.
Seatrium publishes its yard addresses, but access is normally arranged through a named project sponsor with induction, site pass and permit-to-work steps. Ask the sponsor which equipment certifications they accept before you ship devices.
Tank entry normally follows per-vessel gas-free and permit procedures set by the yard, and Zone 1 conditions are assumed in tank spaces. Only equipment with suitable certification would be considered, and the IS-04Z1 is not yet certified. Ask the yard safety team.
