Merger
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merger of Sembcorp Marine and Keppel Offshore & Marine, so older references to separate yards under those names are out of date.

Intrinsically Safe Mobile Phone in Singapore Marine
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. ST Engineering also runs ship repair yards. Tank work, repair and conversion create Zone 1 conditions on vessels. If you are specifying an intrinsically safe mobile phone for Singapore marine and shipyard sector, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WhereSingapore Marine
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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

Field notes · Singapore marine and shipyard sector
More about Singapore marine and shipyard sector that matters for portable equipment
Singapore marine and shipyard sector: infrastructure
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.
Singapore marine and shipyard sector: rules and approvals
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.
Singapore marine and shipyard sector: climate and equipment wear
Heat, humidity and heavy showers are constant, so shipyard crews and handheld devices face both corrosion and moisture ingress year round.
Singapore marine and shipyard sector: projects and investment
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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Singapore marine and shipyard sector. Tank entry, repair and conversion work means climbing through confined spaces with little room for a second device. A handheld intrinsically safe phone is intended to let a surveyor or supervisor record photographs and readings in those spaces. This depends on certification being completed and on the yard's permit rules.

Specifying an intrinsically safe mobile phone for Singapore Marine
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Singapore Marine
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Singapore Marine today?
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.
What does an intrinsically safe mobile phone in Singapore Marine cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which areas at Singapore marine and shipyard sector would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
What makes marine hazardous areas different from onshore plants?
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.
How can a supplier get onto a yard as a contractor?
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.
Is a phone allowed inside a cargo tank on a vessel under repair?
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.
