Services
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.
Loyang Offshore Supply Base in eastern Singapore, near Changi Airport, is run by Toll Offshore Petroleum Services (TOPS). The Loyang base was redeveloped in 2008 with an investment of about 325 million dollars, turning it into a modern offshore supply facility run by Toll Offshore Petroleum Services. Distribution partners for Loyang Offshore Supply Base are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Loyang Offshore Supply Base 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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.
The companies on site and the hazardous-area types a handset is likely to meet there.
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.
The base is near Changi Airport and away from the western petrochemical cluster, so work centres on offshore equipment, vessel support and logistics.
The surrounding Loyang industrial estate in Pasir Ris mainly hosts aviation-related services because of its closeness to Changi Airport, so visitors will find airport-linked businesses alongside the offshore supply base.
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.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Loyang Offshore Supply Base. Staff at a supply base do receiving, inspection and quayside handling more than process rounds. Where a classified area does exist, such as fuel or chemical storage, a handheld intrinsically safe device lets them scan, photograph and record without leaving it. The IS-04Z1 is designed for Zone 1 use.
A distributor for Loyang Offshore Supply Base would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
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 Loyang Offshore Supply Base.
The operator describes round-the-clock manned security, strict access requirements and video surveillance. Expect to be registered in advance and screened at the gate, with any electronic equipment declared. Confirm exact steps with the host company before travelling.
With a wharf able to serve more than 11 vessels at once, vessel mobilisation and demobilisation can overlap, and cranes, containers and fuel transfers share space. Portable devices should be chosen for rough handling, sea air and fast-changing zone boundaries.
Yes. Tenants include oil and gas services companies, each with its own safety rules. A device accepted by one tenant is not automatically accepted by another. Ask the tenant's HSE team for its requirements, and be ready to supply the datasheet and certification status.
