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.
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. An Ex-proof smartphone distributor in Singapore offshore support sector would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Singapore offshore support sector has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Singapore offshore support sector: Vessel mobilisation quays, Hazardous materials storage, Rig and floating-unit conversion | Classified by the site operator |

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 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.
Seatrium offers construction, repair, upgrading and conversion of rigs, floaters and offshore platforms from its Singapore yards.
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.
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.
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 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.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Singapore offshore support sector. A marking check on a conversion project would compare gas group and temperature class with the hydrocarbons the unit will eventually handle, and with the current gas-free status of each space. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued. Project safety teams set the requirement.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Singapore offshore support sector. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Singapore offshore support sector.
Newbuild and conversion projects ramp up in phases, with contractor numbers peaking during outfitting and commissioning. Dates are set by owners and yards, so contact the project team early to learn the approved-equipment list and induction requirements.
The Loyang base describes 24-hour manned security, strict access requirements and video surveillance. Expect advance registration and gate screening, and declare any electronic equipment. Confirm details with the host company before travel.
Buyers here are typically yards, service companies and operators with their own approvals, and a project may follow the unit owner's rules as well. SAMS cannot grant approval. Ask each project's safety team for its device requirements, and confirm with the site operator.
