Wharf
TOPS states that the 970-metre wharf can berth more than 11 vessels at once, including drill ships, semi-submersibles and jack-up rigs.
Loyang Offshore Supply Base in eastern Singapore, near Changi Airport, is run by Toll Offshore Petroleum Services (TOPS). The 320,000 square metre base combines a 970-metre wharf, workshops, warehouses and hazardous-materials storage supporting offshore oil and gas work. This page explains what to look for in an industrial mobile phone for Loyang Offshore Supply Base, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Loyang Offshore Supply Base: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. 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 | Loyang Offshore Supply Base: Offshore equipment workshops, Hazardous materials storage, Wharf and vessel quay handling | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Loyang Offshore. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
TOPS states that the 970-metre wharf can berth more than 11 vessels at once, including drill ships, semi-submersibles and jack-up rigs.
On-site services include vessel testing and afloat repairs, hot works, modular and steel fabrication, and storage for hazardous materials including Class 1.4 explosives.
Its wharf can serve more than 11 vessels at the same time, so supply boats and offshore equipment move through the base continuously.
The site covers 32 hectares in eastern Singapore, close to the aviation and marine hub, which places it away from the Jurong industrial cluster in the west.
Equatorial heat, humidity and sudden heavy showers affect an open wharf and yard, so portable devices used outdoors need good ingress protection and handling discipline.
The base is described as a self-contained ecosystem, with the operator offering logistics management for offshore oil and gas customers from one location.
“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 Loyang Offshore Supply Base. A supply base with many tenants means many small fleets rather than one large one. A tenant could enrol its handsets individually. The IS-04Z1 runs Android 16 and is designed for EMM and MDM, and charging should be in an unclassified area, such as an office or workshop bay outside the zone.
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 offshore equipment workshops, hazardous materials storage, wharf and vessel quay handling, hot works and afloat repair areas. 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.
The base is operated by Toll Offshore Petroleum Services, part of Toll Group, and covers 32 hectares in eastern Singapore. Because it is a managed logistics site, tenant and contractor rules are normally set by the operator and by each tenant's own HSE team.
Yes in places: workshops, fuel and chemical stores, and equipment being prepared for offshore service can create classified areas, while the wharf area is mostly open air. The classification varies by building and tenant, so ask the tenant for its zone plan.
Not wholly. The base has workshops, storage and quay handling, and which tenants hold classified areas has not been verified. Chemical and fuel storage may be classified. Ask the tenant's HSE team or the base operator before assuming an Ex rating is required for the task.
