Base facilities
TOPS lists a 970-metre wharf, workshops and storage for hazardous materials at Loyang, with hot works and afloat repairs among its 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. Equipment repair, vessel mobilisation and conversion work create hazardous areas. If you are specifying an IECEx mobile phone for Singapore offshore support sector, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Singapore Offshore Operations. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
TOPS lists a 970-metre wharf, workshops and storage for hazardous materials at Loyang, with hot works and afloat repairs among its services.
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.
Equatorial heat and heavy showers affect open decks and yards throughout the year, so offshore equipment is prepared and tested in hot, humid conditions.
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.
Seatrium's work for offshore customers spans oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades.
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.
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.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
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.
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.
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.
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.
