Hazardous Area 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. 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: who works there
Seatrium organises its business into oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades, all based around Singapore.
Singapore marine and shipyard sector: logistics and access
Singapore sold 56.775 million tonnes of marine fuel in 2025, the largest bunkering volume of any port, so tanker, barge and fuel-transfer operations are a daily feature of its waters.
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.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Singapore marine and shipyard sector. The hazardous areas in this sector are vessel tank and cargo spaces, repair and conversion work, paint and coating areas and offshore unit conversion. Yards and vessel owners classify them, and conditions change with each vessel. SAMS does not classify areas, so a specifier should ask the yard safety team.

Questions · Singapore Marine
Frequently asked questions
Can we buy a hazardous area mobile phone in Singapore Marine today?
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.
What does a hazardous area mobile phone 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
