More about Senoko that matters for portable equipment
Senoko: industry on the ground
Senoko Power Station is the largest power station in Singapore and was commissioned in 1976, after planning began in the early 1970s under the Public Utilities Board.
Senoko: infrastructure
Its authorised capacity is 2,800 megawatts from seven operating units, and it runs mainly as a combined-cycle gas plant, so gas-turbine halls and fuel systems form its main classified areas.
Senoko: industry on the ground
Natural gas supplies over 90 percent of Singapore's electricity, up from less than 20 percent in 2000, which is why large gas-fired plants such as Senoko dominate the local hazardous-area picture.
Senoko: infrastructure
Combined-cycle units 6 and 7, rated at 431 megawatts each, were completed by 2012 by repowering the second oil-fired steam stage, while units 3 to 5 at 365 megawatts each followed by 2004.
The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Senoko. A plant of this scale runs shift crews plus outage contractors, so a shared pool of handhelds under EMM or MDM suits it. Enrolment, app lists and lock-down policies should be set before devices reach site. Charging belongs in a safe area such as a control room, and connectivity rules are the plant's.
The route · specification
Specifying an industrial smartphone for Senoko Industrial Zone
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Senoko Industrial Zone
Frequently asked questions
Can we buy an industrial smartphone in Senoko Industrial Zone 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 industrial smartphone in Senoko Industrial Zone 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 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Which areas at Senoko would use it?
Likely candidates are power plant gas and fuel systems, fuel storage tanks and terminal services. 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.
When are outages most likely to need extra field devices?
Combined-cycle units are taken offline for planned inspections, and contractor numbers rise during those windows. Dates are set by the operator and the grid, so ask the plant's maintenance planner about the outage calendar and the approved-equipment list.
Does the fuel mix change the equipment requirement?
Natural gas has been the main fuel since 1992, with fuel oil as a back-up. Gas groups and temperature classes differ between natural gas and oil vapour, so devices should be matched to the gas group and temperature class stated in the plant's area classification.
Is the whole Senoko estate a hazardous area?
No. The classified areas are mostly the gas and fuel systems and fuel tanks at the power station, not the estate as a whole. Other tenants have not been checked here. Ask the relevant operator for its classification before assuming a zone, and confirm with the site operator.
