Adura is the Aberdeen-headquartered company that Shell and Equinor formed on 1 December 2025 by combining their UK North Sea interests, and it now sits behind most of the installations a UK explosion proof mobile phone buyer will be asked about in the central and northern North Sea. This page is for the HSE, telecoms and procurement staff who decide what may be carried into a Zone 1 area on those installations, and for the contractors who work to their rules. The IS-04Z1 is pre-launch, with certification in progress ahead of Q4 2026. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
Adura took over Equinor and Shell’s interests in twelve producing assets and projects in execution: Mariner, Rosebank, Buzzard, Shearwater, Penguins, Gannet, Nelson, Pierce, Jackdaw, Victory, Clair and Schiehallion. It is a new company with about 1,200 people, so the layers a supplier would normally rely on, an approved-equipment list, a site induction, a telecoms standard, are being rebuilt or inherited asset by asset, and nobody outside the company should assume which. Operatorship also differs from field to field. Press coverage of the formation puts Shearwater under a Shell-held operating stake, while BP operates Clair and CNOOC operates Buzzard, so a contractor on those two may be working to a different duty holder’s rules than Adura’s own. Mariner is the clearest single case: an ultra-heavy oil field about 150 km east of Shetland, produced from the Mariner A platform and exported through the Mariner B floating storage unit.
Five conditions come up whenever an offshore HSE or telecoms engineer reviews a handset, and each maps to something the IS-04Z1 is designed to answer.
Mariner’s oil is piped after dilution, so the hydrocarbon vapour on deck comes from the diluent as well as the crude. The IS-04Z1 is designed to an II 2 G Ex ib IIC T4 target, a Zone 1 gas marking at the broadest gas group, so the reviewer is not left checking the handset against each stream separately.
A platform deck is hosed down and rained on far more often than it is dusty. IP68 sealing and rugged build are the first things a deck-level reviewer reads on the datasheet, ahead of any software feature.
There is no charging point in the process area, so the 4,000 mAh cell is sized to carry a full twelve-hour shift with the camera and GNSS in use, with charging at handover rather than at the walkway.
The 50 MP camera with PDAF gives photographs a planner onshore can read, such as a flange tag, a corrosion patch or a relief valve label, which is what avoids a second trip into the zone for the same question.
Android 16 with Android Enterprise and the major MDM consoles lets Adura IT enrol its own units and restrict the camera or applications by policy, while contractors’ units can be handled the same way instead of as an exception.
Equinor’s reporting for 2025 records new production and water injection wells drilled from the Mariner A platform. A drilling crew inside a classified area works to a permit and a daily report, and an enrolled handset can carry both without a trip to the office.
A shuttle tanker offload is a watched operation with set communications. A Zone 1 handset on the deck gives the loading master a photograph, a position and a call to the control room from the same device.
Shearwater, Gannet, Nelson and Pierce are worked by campaign crews who fly out, finish a scope and leave. A handset they are issued on arrival and wiped on departure suits that pattern better than one that stays with a person.
Large North Sea duty holders normally layer a vendor or equipment approval on top of the certificate, but Adura is a new company and we will not guess at its process. Ask its procurement and HSE teams what they require for a handheld device, and whether legacy Shell or Equinor approvals carry across.
Not necessarily. Equinor’s announcement lists the assets as Adura’s portfolio, but press coverage places operatorship of Clair with BP and Buzzard with CNOOC. The duty holder for a given installation sets its device rules, so check who it is before a contractor’s kit is specified.
Offshore rotations vary, with two-on-two-off and three-on-three-off patterns both in use across the North Sea. A device that is enrolled in an MDM can be issued, reassigned and wiped at crew change, which is the practical answer to shared units.
No. The IS-04Z1 is pre-launch, certification is in progress, and SAMS has no supply agreement, pilot or relationship with Adura. The page describes what an Adura team would ask for and what the device is designed for.
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 United Kingdom. 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.
