A reading that settles a dispute
Quantity and quality are commercial points. A photograph of the meter or sample label, stamped with position and time at the manifold, is stronger evidence than a figure copied later on shore.
Singapore is the world’s largest bunkering port, and the work behind that is gauging, sampling and metering on bunker tankers, at jetties and at the anchorages. This page is for the barge masters, surveyors, terminal operators and HSE teams who must decide what explosion proof mobile phone in Singapore may be carried on deck. The IS-04Z1 is pre-launch and no certificate has been issued. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.

Bunkering means delivering marine fuel to a ship, and in Singapore most of it is done by licensed tankers alongside the receiving vessel at the anchorages, with some at the wharves. The Maritime and Port Authority of Singapore licenses bunker suppliers and requires bunker deliveries of marine fuel oil to be measured by mass flow meter, so a surveyor, a barge crew and the receiving ship’s officers all stand around the same measurement. Residual fuel has a high flashpoint and is not the main ignition problem. The hazard comes from what else is on or near the tanker: light cargo and slops, vapour in cargo tanks, marine gas oil mixing, LNG and other alternative fuels as they come into the port, and the offshore and marine yards at Tuas that reach the same waters. The deck of a bunker tanker is a classified area in practice, and a phone carried onto it is a possible ignition source.
A bunker delivery is short, wet and watched by several parties. Whatever is recorded on the deck needs to survive an argument later.

Open deck means spray, rain and salt air. IP68 sealing and rugged build suit that environment, with the certificate stating the ambient range for the marking.
A surveyor often goes from one tanker to another by boat, so there is no desk in between. A 4,000 mAh battery covers a full day of jobs, and four-constellation GNSS gives a position on open water.
Barge crew, surveyor and terminal operator each use different applications. Android Enterprise enrolment allows a company to restrict the camera or apps by policy and to control a fleet from an existing MDM console.
The vessel’s class rules, the port authority’s requirements and each supplier’s own procedures decide what may be used on board. Ask the supplier’s HSE team; a handset does not replace the vessel’s radios.
A tanker mate photographs the meter readings and the connection at the manifold, calls the receiving ship and records the time, all without putting a device down.
A surveyor takes a sample, photographs the seal and records the position, then sends it to the office when back in a safe area.
A terminal operator at a jetty loads a bunker tanker and records the line-up with the same device used for tank rounds.
No. Marine communications rules apply to vessels. The handset covers calls, photographs and records around them.
Residual fuel has a high flashpoint, but the deck, the tanks and the cargo handling around a tanker still create classified areas. Which areas count is decided by the vessel and operator, not by the product alone.
Those fuels have different gas groups and temperatures. The IS-04Z1 marking target is IIC, but a site must check the temperature class against its own fuel.
No. SAMS has no named customers in Singapore and this page does not imply any. Certification is in progress ahead of the Q4 2026 launch.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Singapore. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
