Jetties
Two jetties accommodate LNG vessels from 2,000 to 265,000 cubic metres, up to the largest Q-Max carriers.
The SLNG Terminal sits on a 40-hectare plot at the southern-most tip of Jurong Island and began commercial operations in May 2013. Gas and LNG facilities are covered by Singapore's Workplace Safety and Health framework, and Major Hazard Installations need documented area classification drawings under MOM and SCDF rules. This page explains what to look for in a hazardous area smartphone 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |

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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Two jetties accommodate LNG vessels from 2,000 to 265,000 cubic metres, up to the largest Q-Max carriers.
The terminal supplies about half of Singapore's natural gas for power generation, the remainder coming by pipeline.
SLNG plans to develop a second LNG terminal, an offshore facility slated to be operational by the end of the decade, in addition to the Jurong Island terminal.
The terminal supplies about 50 percent of the natural gas used for Singapore's electricity, with the rest coming by pipeline, and it could cover all present demand if required.
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.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Singapore LNG Terminal, Jurong Island. The classified areas at this terminal are the LNG storage tanks, the jetties and loading arms, regasification and send-out, and small-scale reloading. SLNG classifies these, not SAMS. A specifier should ask for the area classification documents and keep any device off a location whose zone has not been confirmed.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
