Loyang Offshore Supply Base: rules and approvals
Security is manned around the clock with strict access requirements and video surveillance, so visitors and contractors should expect pre-registration and screening at the gate.
Loyang Offshore Supply Base: background
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.
Loyang Offshore Supply Base: industry on the ground
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.
Loyang Offshore Supply Base: logistics and access
Its wharf can serve more than 11 vessels at the same time, so supply boats and offshore equipment move through the base continuously.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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.

Questions · Loyang Offshore
Frequently asked questions
Can we buy an intrinsically safe smartphone in Loyang Offshore today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an intrinsically safe smartphone in Loyang Offshore cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
Which areas at Loyang Offshore Supply Base would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
Who runs the Loyang Offshore Supply Base?
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.
Are there hazardous areas at an offshore supply base?
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.
Is Loyang a hazardous-area site?
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.
