Ownership change
Seatrium describes itself as formed from the 2023 merger of Sembcorp Marine and Keppel Offshore & Marine, so older descriptions of Keppel-run yards are out of date.

Keppel Shipyard (now Seatrium yards), Singapore: climate and equipment wear
Singapore has an equatorial climate with steady heat, high humidity and frequent afternoon rain, so outdoor yard work exposes handheld equipment to moisture and sun throughout the year.
Keppel Shipyard (now Seatrium yards), Singapore: infrastructure
Seatrium's Singapore yards include Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard, plus the offshore-focused Crescent and Pandan yards, so contractors may work at several sites in one project.
Keppel Shipyard (now Seatrium yards), Singapore: geography and layout
The yards are spread widely: Admiralty Yard is on Admiralty Road West in the north, while Benoi, Pioneer, Tuas and Tuas Boulevard yards sit in the industrial west of the island.
Keppel Shipyard (now Seatrium yards), Singapore: infrastructure
Pioneer Yard offers a 1,400 metre quay with 8 to 10 metres of depth, and Crescent Yard has a 740 metre quay with 6 metres of depth, supporting several vessels alongside at once.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Keppel Shipyard (now Seatrium yards), Singapore. Repair and conversion work means inspectors moving through tanks, cargo spaces and dry docks, often on short jobs. A handheld intrinsically safe device lets them photograph defects and record measurements while permits are in force. The IS-04Z1 is designed for Zone 1 use, with a 4,000 mAh battery.

Questions · Keppel Shipyard
Frequently asked questions
Can we buy an intrinsically safe smartphone 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 intrinsically safe smartphone in Keppel Shipyard cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
