Supply base
A government speech in 2013 described a S$300 million upgrade of Loyang Offshore Supply Base, supporting repair of specialised offshore equipment and mobilisation of offshore vessels.

Intrinsically Safe 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. Equipment repair, vessel mobilisation and conversion work create hazardous areas. If you are specifying an intrinsically safe mobile phone for Singapore offshore support sector, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WhereSingapore Offshore Operations
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Singapore offshore support 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about Singapore offshore support sector that matters for portable equipment
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.
Singapore offshore support sector: projects and investment
Keppel Shipyard secured an FPSO conversion contract worth 89 million dollars in 2015, covering repair, upgrade and modification, an example of the conversion work done in Singapore.
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.
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 offshore support sector. Mobilising vessels at a quay, repairing offshore equipment in workshops and walking down a converted unit are all tasks where a hand-held record of photos and checks helps. A handheld intrinsically safe phone is intended for that, subject to certification in progress and the project's own permit system.

Specifying an intrinsically safe 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 intrinsically safe 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 intrinsically safe 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.
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 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.
