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.

ATEX and IECEx Mobile Phone in Singapore Offshore Operations
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. This page explains what to look for in an ATEX and IECEx mobile phone for Singapore offshore support sector, and where the IS-04Z1 stands against that list today.

Singapore offshore support sector: background
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.
Singapore offshore support sector: climate and equipment wear
Equatorial heat and heavy showers affect open decks and yards throughout the year, so offshore equipment is prepared and tested in hot, humid conditions.
Singapore offshore support sector: projects and investment
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.
Singapore offshore support sector: who works there
Seatrium's work for offshore customers spans oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Singapore offshore support sector. Rig and FPSO projects bring owners, class societies and yard contractors together, so reviewers would expect both ATEX and IECEx evidence for a handheld used on conversions. The IS-04Z1 certification is in progress and only a datasheet exists today. The yard, the service company or the unit owner decides which certificates it will accept.

Specifying an ATEX and IECEx mobile phone for Singapore Offshore Operations
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Singapore Offshore Operations
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Singapore Offshore Operations 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 ATEX and IECEx mobile phone in Singapore Offshore Operations cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Singapore offshore support sector would use it?
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.
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.
What hazardous areas arise on an FPSO under construction?
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.
Where is offshore equipment prepared in Singapore?
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.
Does demand for devices change with project timing?
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.
