Singapore shipyards: background
In 2002 Keppel Shipyard was combined with Keppel FELS and Keppel Singmarine to form the Keppel Offshore and Marine group, which became part of Seatrium in 2023.
Singapore shipyards: who works there
Seatrium lists its Singapore yards at Admiralty Road West, 15 Benoi Road, 50 Gul Road, 51 Pioneer Sector 1 and 80 Tuas South Boulevard, each with its own gate and switchboard.
Singapore shipyards: projects and investment
Two large FPSOs, P-80 and P-82, were christened at the Tuas Boulevard Yard, each designed to produce 225,000 barrels of oil a day.
Singapore shipyards: infrastructure
Pioneer Yard has a 1,400 metre quay with 8 to 10 metres of depth, with a second quay of 350 metres, giving long alongside berths for repair work.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Singapore shipyards. On a newbuild or repair job, explosion-proof is a loose term. Flameproof Ex d suits fixed fittings, while a handheld phone taken into a vessel tank depends on intrinsic safety. The IS-04Z1 is designed around intrinsic safety, with certification in progress and each yard's permit rules applying.

Questions · Singapore Shipyard
Frequently asked questions
Can we buy an explosion proof smartphone in Singapore 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 explosion proof smartphone in Singapore 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which areas at Singapore shipyards would use it?
Likely candidates are vessel tank spaces, dry dock and repair work, paint and coating shops, offshore conversion. 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.
Do large docks create special conditions?
Large graving docks hold very big vessels and many contractors at once, so crowding, crane lifts and hot work overlap. Hazardous-area controls are managed per vessel by the yard's safety team and the owner's representative.
Which Singapore shipyards are major sites for Zone 1 work?
Seatrium's yards at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard are the large repair and conversion sites, and other yards operate in the Jurong area. Zone 1 conditions arise inside tanks and pump rooms during repair and coating work.
Do gas-free procedures replace the need for certified equipment?
Not automatically. Tank entry and hot work normally follow per-vessel gas-free and permit procedures set by the yard, and some yards still require certified equipment in certain spaces. The IS-04Z1 has no certificate yet. Ask the yard safety department which rule applies.
