More about Keppel Shipyard (now Seatrium yards), Singapore that matters for portable equipment
Keppel Shipyard (now Seatrium yards), Singapore: background
Keppel privatised its offshore and marine business in 2001, and in 2002 combined Keppel Shipyard with Keppel FELS and Keppel Singmarine to form the Keppel Offshore and Marine group.
Keppel Shipyard (now Seatrium yards), Singapore: who works there
Seatrium, formed in 2023, groups its work into oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades.
Keppel Shipyard (now Seatrium yards), Singapore: projects and investment
Repair and upgrade scope at the Singapore yards covers gas carriers (LNG and LPG), floating production units, jack-ups and semi-submersibles, and jumboisation or dejumboisation, each with different tank and gas-freeing routines.
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.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Keppel Shipyard (now Seatrium yards), Singapore. Vessel tanks, paint and solvent areas and FPSO conversion work involve solvent vapour and fuel residues, so a marking check should read the gas group and temperature class from the vessel's gas-free or hazard assessment. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, still a target.

Questions · Keppel Shipyard
Frequently asked questions
Can we buy an Ex-proof mobile phone in Keppel Shipyard today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an Ex-proof mobile phone in Keppel Shipyard cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
