The term · industrial
What “industrial” means for a smartphone
“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 Keppel Shipyard (now Seatrium yards), Singapore. Repair and conversion projects bring many subcontractor crews, each employer with its own devices. Permit handling per vessel means device control matters. The IS-04Z1 runs Android 16 and is designed for EMM and MDM, so a yard or subcontractor could enrol, lock and reassign handsets, with charging outside the hazardous space.

Questions · Keppel Shipyard
Frequently asked questions
Can we buy an industrial mobile phone in Keppel Shipyard today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an industrial mobile phone in Keppel Shipyard cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
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.
Which areas at Keppel Shipyard (now Seatrium yards), Singapore would use it?
Likely candidates are vessel tank and cargo spaces, offshore unit conversion, paint and solvent areas, dry dock work. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
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.
Does the work differ between FPSO conversion and ordinary repair?
Conversion projects involve large process and tank systems that become classified areas when commissioned, while repair work is more tank-by-tank and short term. Expect tighter control of electronics on conversion hulls close to hydrocarbon systems. The vessel owner and yard HSE team set the rules for each project.
Is Keppel Shipyard still operating under the Keppel name?
Keppel's offshore and marine yards are now part of Seatrium, formed in 2023 from Sembcorp Marine and Keppel Offshore and Marine. Former Keppel yard sites in Singapore are now listed under Seatrium, so use that name when registering for contractor access or supplier approval.
Are older Keppel yard references still correct?
No. Seatrium was formed in 2023 and Keppel's yards now operate under it, and the Gul yard was sold to ST Engineering. Use current names when contacting yards. Details of individual Seatrium yards were not verified, so ask the company which yard serves your project.
