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. If you are specifying an industrial 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.
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 |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Singapore offshore support sector: Rig and floating-unit conversion, Offshore equipment repair workshops, Vessel mobilisation quays | 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.
The companies on site and the hazardous-area types a handset is likely to meet there.

Seatrium offers construction, repair, upgrading and conversion of rigs, floaters and offshore platforms from its Singapore yards.
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.
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.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Singapore offshore support sector. Activity depends on the timing of rig and FPSO projects, so headcount swings between quiet periods and peaks. A managed fleet under EMM or MDM can be sized up and down, with enrolment before devices reach the yard. Charging stays in safe areas, and the project sets network and app rules.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
