Eastern location
The base is near Changi Airport and away from the western petrochemical cluster, so work centres on offshore equipment, vessel support and logistics.

The term · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Loyang Offshore Supply Base. Loyang is in eastern Singapore near Changi Airport, so tropical heat, humidity and quayside spray apply, with rain on open yards. IP68 on the IS-04Z1 helps against water and dust. It is an ingress rating only and does not replace the Ex marking where a classified area exists.

Questions · Loyang Offshore
Frequently asked questions
Can we buy a rugged mobile phone 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 a rugged mobile phone in Loyang Offshore cost?
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.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are 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.
