Heavier-than-air vapour at low points

Norway lands its gas at a short list of coastal plants: Kårstø, Kollsnes and Nyhamna for pipeline gas, Melkøya for LNG, and Mongstad and Sture for crude oil. This page is about the explosion proof mobile phone question at those plants, where gas, condensate and liquids sit alongside compression and a marine jetty. The IS-04Z1 is designed for Zone 1 and Zone 21 duty; its ATEX and IECEx certification is in progress ahead of the Q4 2026 launch. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
The sector is small in number of sites and large in scale. Kårstø, Kollsnes and Nyhamna are operated by Gassco and between them take the gas from the shelf's main export systems. Melkøya, an island at Hammerfest, liquefies gas from the Snøhvit field in the Barents Sea, and Equinor operates it. Mongstad and Sture are crude oil terminals that receive and load oil from shelf fields, and Mongstad also has a refinery and a carbon capture test centre. Northern Lights, the CO2 receiving terminal at Øygarden, adds a newer type of plant with its own hazards. What they share is a fixed fence, a control room, a continuous process and a jetty. Operators are listed on the Equinor and Gassco pages.
A coastal gas plant is a continuous, heavily instrumented site. The handset has to add something the control room does not already have.

Rounds cover large areas in rain, wind and sleet. IP68 sealing and rugged build are aimed at that, and the 4,000 mAh battery is sized for a shift.
Most of these plants are gas, but Zone 21 dust can appear in packaging or bulk areas elsewhere in the sector. The design target covers both.
Plants run around the clock with shift operators. The big planned stops, known as revisjonsstans, bring hundreds of contractors from many firms into the process for weeks. Gassco publishes planned maintenance on its transport system in advance, so the dates are known well ahead. Marine staff work at the jetty in parallel with process crews.
Operators in this sector share a qualification register for suppliers, Magnet JQS, formerly EPIM JQS, and then apply their own technical requirements to Ex equipment. SAMS has no approval from any of them and has not applied; ask each operator's procurement and HSE teams for the process on their plant.
Readings, photographs and a voice call to the control room from one device, inside the classified boundary.
A supervisor at the manifold can communicate and record without carrying a separate radio into the zone.
Contractors are enrolled for the length of the stop, issued the job pack and permits, and wiped at the end.
Kårstø, Kollsnes, Nyhamna, Melkøya, Mongstad, Sture and the CO2 receiving terminal at Øygarden. For each, the operator's classification drawings decide the zones and the gas group, not this page.
The flammable gas is the same family, but LNG adds cryogenic temperatures and refrigerant hydrocarbons, and its classification is set by the plant design. The device's temperature range and the area's temperature class are both checked against the datasheet.
No. The device is pre-launch and no certificate has been issued. SAMS supplies through authorised distributors after launch, and nothing goes into a classified area until the certificate covering it exists.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Norway. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
