Climate
Hot, humid equatorial climate with frequent rain.
Citra Shipyard, founded in 2006, runs two Batam yards: a 42 hectare site at Kabil and a 24 hectare site at Kampung Becek, building barges, tugs, tankers and offshore supply vessels. Painting, tank cleaning, gas freeing and hot work on vessels and offshore modules create temporary hazardous areas. This page explains what to look for in a rugged smartphone for Batam shipyards, Riau Islands, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Batam shipyards, Riau Islands: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Batam shipyards, Riau Islands: Vessel tank and cargo spaces, Paint and coating shops, Fuel and gas storage | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Batam Shipyard. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

A recruitment-sector analysis puts the number of yards on Batam at roughly 130, so conditions vary from yard to yard.
Batam is an industrial island about 20 km off Singapore's south coast, within a free trade zone in the Indonesia-Malaysia-Singapore Growth Triangle, which makes it a convenient base for marine contractors serving regional yards.
Batam has a tropical rainforest climate with heavy rainfall all year, so yard equipment faces constant humidity and frequent downpours rather than a dry season.
Two thirds of Batam's population are migrants, and Indonesian is the common working language, with Malay widely understood by visiting contractors from Singapore and Johor.
Shipbuilding and electronics manufacturing are the island's main industries, and proximity to Singapore's ports speeds the movement of goods and spare parts to the yards.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Batam shipyards, Riau Islands. Batam is hot and humid with frequent rain, and yards sit by the sea. Handsets face wet decks, dust from blasting and spray. IP68 describes ingress against dust and water only. It is not explosion protection, which must still be matched to the space being entered.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
Likely candidates are vessel tank and cargo spaces, paint and coating shops, fuel and gas storage, offshore module fabrication areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
They can. Repair and offshore conversion often involve ships that have carried fuel or chemicals, which raises the chance of residual vapours, so gas testing and permit-to-work control are usually stricter. Ask the yard for its tank-entry and hot-work procedures.
Heavy rainfall all year and a tropical rainforest climate mean constant moisture, so devices typically need good ingress protection, sealed charging contacts and regular drying and cleaning. Check the rating and charging method against the yard's safety rules.
Not always, but during painting, tank cleaning, gas freeing or hot work the space is usually treated as hazardous. The yard's gas-free procedure and permit decide. Do not take a non-Ex device into such a space unless the permit explicitly allows it.
