Explosion-Proof 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. Equatorial heat and heavy showers affect open decks and yards throughout the year, so offshore equipment is prepared and tested in hot, humid conditions. If you are specifying an explosion proof mobile phone for Singapore offshore support sector, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Singapore offshore support sector: who works there
Seatrium's work for offshore customers spans oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades.
Singapore offshore support sector: projects and investment
Two of the world's largest FPSOs, P-80 and P-82, were christened at Seatrium's Tuas Boulevard Yard, each able to produce 225,000 barrels of oil a day, with an industry-first dual sailaway.
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
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.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Singapore offshore support sector. On an FPSO or rig conversion, explosion-proof is shorthand. Flameproof Ex d enclosures protect fixed equipment, while a handheld phone used during commissioning walk-downs relies on intrinsic safety. The IS-04Z1 is designed around that second concept, with certification still in progress and each project's rules applying.

Specifying an explosion proof 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 an explosion proof 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 an explosion proof mobile phone in Singapore Offshore Operations 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
