Storage and capacity
SLNG states three tanks of 180,000 cubic metres each plus a fourth of 260,000 cubic metres, with average send-out capacity of 9 million tonnes per annum and a peak of around 11.
The SLNG Terminal sits on a 40-hectare plot at the southern-most tip of Jurong Island and began commercial operations in May 2013. It receives, stores and sends out natural gas, mainly for power generation, so tank, jetty and send-out areas are gas-hazardous. This page explains what to look for in an ATEX and IECEx mobile phone for Singapore LNG Terminal, Jurong Island, 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 Singapore LNG Terminal, Jurong Island: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. 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 Singapore LNG. 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.
SLNG states three tanks of 180,000 cubic metres each plus a fourth of 260,000 cubic metres, with average send-out capacity of 9 million tonnes per annum and a peak of around 11.
Two jetties accommodate LNG vessels from 2,000 to 265,000 cubic metres, up to the largest Q-Max carriers.
The SLNG Terminal has an annualised average gas supply capacity of 9 million tonnes per annum and a peak capacity of up to 11 million tonnes per annum.
It has two jetties and four storage tanks: three of 180,000 cubic metres and a fourth of 260,000 cubic metres, one of the largest LNG tanks in the world.
Natural gas now generates over 90 percent of Singapore's electricity, compared with under 20 percent in 2000, so continuity of send-out is treated as a national energy-security matter.
SLNG began building a new LNG truck loading facility in August 2025, adding road-tanker loading to the terminal, and describes itself as the owner of Asia's first open-access, multi-user LNG terminal.
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 LNG Terminal, Jurong Island. For an LNG terminal on Jurong Island, a reviewer would expect ATEX and IECEx evidence for any device entering the tank, jetty or send-out areas, because visiting vessel crews, inspectors and contractors are international. The IS-04Z1 certification is in progress, so only a datasheet can be offered now. SLNG decides what it accepts.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are lng storage tanks, lng jetties and loading arms, regasification and send-out. 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.
Typical classified areas include jetty loading arms and manifolds, tank roofs and vent systems, pump and vaporiser areas and send-out metering. Natural gas is typically treated as gas Group IIA, but check the gas group and temperature class against the terminal's own classification.
SLNG plans a second offshore terminal by the end of the decade and has expanded the current one in stages. Construction and commissioning phases bring many contractors on site, so approved-equipment lists and induction rules apply from day one; confirm them with the project team.
The tank, jetty and send-out areas create Zone 1 and Zone 2 conditions according to the site description, and small-scale reloading is also a gas area. SLNG classifies them. Ask it for the classification drawings and do not assume zones from the general description.
