IECEx Smartphone in Singapore Offshore Operations
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. Equipment repair, vessel mobilisation and conversion work create hazardous areas. If you are specifying an IECEx smartphone for Singapore offshore support sector, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Singapore offshore support sector. Offshore units built or converted in Singapore usually end up working in other regions under international operators. That is the situation for which IECEx exists: one certificate of conformity and a schedule of conditions that travel with the equipment. The IS-04Z1 has neither yet, because certification is in progress.

Specifying an IECEx smartphone 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 IECEx smartphone in Singapore Offshore Operations today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an IECEx smartphone 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
