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. If you are specifying an industrial mobile phone for Singapore LNG Terminal, Jurong Island, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. 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.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Singapore LNG Terminal, Jurong Island. The terminal sits on a protected part of Jurong Island, so contractor teams need security passes and a managed device fleet should be enrolled before arrival. EMM or MDM policies, app lists and charging in safe areas should be agreed with SLNG. Jetty and tank crews work in shifts around vessel schedules.
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.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
