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merger of Sembcorp Marine and Keppel Offshore & Marine, so older references to separate yards under those names are out of date.

Industrial Smartphone 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 industrial smartphone for Singapore marine and shipyard sector, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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 · industrial
What “industrial” means for a smartphone
“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 Singapore marine and shipyard sector. Yards run large temporary workforces of subcontractors, so a managed pool of phones under EMM or MDM helps keep apps and access under control. Devices should be enrolled before reaching the yard, and charged in safe areas outside tanks. Each yard sets its own network and device rules.

Specifying an industrial smartphone 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 industrial smartphone 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 industrial smartphone in Singapore Marine cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
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.
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.
