Hazardous Area Mobile Phone in Singapore Offshore Operations
Singapore supports offshore oil and gas through rig and floating-unit work at Seatrium yards and through the Loyang Offshore Supply Base run by Toll Offshore Petroleum Services. Alongside the main Singapore yards, Seatrium operates offshore-specific yards at Crescent and Pandan, so rigs and floating units are fitted out at several locations. This page explains what to look for in a hazardous area mobile phone for Singapore offshore support sector, and where the IS-04Z1 stands against that list today.

Singapore offshore support sector: who works there
Seatrium was formed in 2023 when Sembcorp Marine took over Keppel Offshore & Marine and was renamed, and it runs shipyards in Singapore, Indonesia, the United Kingdom and Brazil.
Singapore offshore support sector: infrastructure
The Loyang base covers 32 hectares and its wharf area can serve more than 11 vessels at once, with 24-hour manned security and video surveillance.
Singapore offshore support sector: background
Toll Offshore Petroleum Services redeveloped its Loyang base in 2008 with an investment of about 325 million dollars, creating a dedicated offshore supply facility in eastern Singapore.
Singapore offshore support sector: climate and equipment wear
Equatorial heat and heavy showers affect open decks and yards throughout the year, so offshore equipment is prepared and tested in hot, humid conditions.
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 offshore support sector. Hazardous areas here arise at FPSO and rig conversion, offshore equipment repair workshops, vessel mobilisation quays and supply base storage. Operators and yards classify them, and the picture changes as projects start and finish. SAMS does not classify areas, so a specifier should ask each project's safety team.

Specifying a hazardous area mobile phone for Singapore Offshore Operations
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 Offshore Operations
Frequently asked questions
Can we buy a hazardous area mobile phone in Singapore Offshore Operations 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 Offshore Operations 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 offshore support sector would use it?
Likely candidates are rig and floating-unit conversion, offshore equipment repair workshops, vessel mobilisation quays, hazardous materials storage. 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 hazardous areas arise on an FPSO under construction?
As process systems, tanks and flare or vent systems are installed and commissioned, parts of the hull become classified areas, with zones growing as hydrocarbons are introduced. Before commissioning, rules are mostly about hot work and gas freeing. Ask the project HSE team where zones apply.
Where is offshore equipment prepared in Singapore?
Common locations are the Loyang Offshore Supply Base in the east, where equipment is stored and shipped, and Seatrium's yards in the west, where rigs and FPSOs are built or converted. Each site sets its own access and permit rules.
Does demand for devices change with project timing?
Activity depends on the timing of rig and FPSO projects, so fleet size can change quickly. A managed device pool helps, but SAMS has no stock or lead times to quote because the IS-04Z1 is pre-launch. Plan any pilot well ahead of a project's peak.
