Fuel Storage Tank Solution
Automated fuel terminals, from SPOB unloading to the dispenser nozzle. Designed, fabricated, built and commissioned by Rexline’s own teams.
One Contractor, One Control Room From SPOB to Dispenser
PT Rexline Engineering Indonesia designs, fabricates, builds, automates and commissions complete fuel storage and handling terminals for mining, port, industrial and power generation operations across Indonesia. Fuel is pumped straight off the SPOB into an automated tank farm, then loaded into road tankers and dispensed to site vehicles. Every pump, valve, tank level and dispenser runs on one Siemens PLC and SCADA system in the MCC room, your head office can follow the same screens live, and an automatic hydrant system protects the whole site.

How The System Work
Seven parts, one EPC contract and one Siemens SCADA system, all designed, built and commissioned by Rexline.
SPOB unloading and pumping station
Rexline’s pumps draw fuel straight from the SPOB, then filter and meter it on its way to the tanks.
Automated tank farm
Tanks from 10 to 2,000 kL with level transmitters, high-level alarms and motorised valves.
Truck loading gantry
Overhead loading bays for road tankers, metered and interlocked.
Light vehicle refuelling
Metered dispensers for site vehicles, fed through an emergency shutdown valve.
MCC and Siemens SCADA room
One screen starts pumps, moves valves and shows every level, flow and alarm.
Head office monitoring
The same live data at your head office over a secure link.
Automatic fire protection
Fire water tank, self-starting fire pumps, hydrant ring main, foam and monitors.
Any Capacity, From 10 KL to 2,000 KL
Compact and mobile tanks for small or relocatable operations, vertical cone-roof tanks for bulk storage. Each tank is sized to your consumption and delivery pattern, and specified to ESDM requirements and your project specification.

Drawn to one scale by volume to show the range. Final dimensions are set by the design for each site.

SPOB Unloading
Fuel comes straight off the SPOBRexline’s unloading pumps draw your fuel directly from the SPOB at the jetty and deliver it, filtered and metered, into the tank farm. The operator starts, watches and stops each transfer from the SCADA screen.
What’s included
- Unloading pumps in a duty and standby arrangement
- Suction strainer and filter with differential-pressure monitoring
- Flow meter with live flow on the SCADA screen
- Pressure switches and explosion-proof pressure transmitters
- Motorised valves opened and closed from SCADA
- Emergency shutdown valves on the transfer line
- Jetty hose connection, pipeline, supports and expansion loops
The transfer line as configured on the SCADA of the Merauke terminal, with its instrument tags.
Tank Farm
Every tank on one screenEach tank carries a level transmitter, high and high-high level alarms and motorised inlet and outlet valves, all wired to the Siemens PLC. The operator sees every level in real time, and interlocks stop filling before a tank can overfill.


- Tanks from 10 to 2,000 kL, horizontal or vertical
- Level transmitter on every tank
- High and high-high level alarms with interlocks
- Motorised inlet and outlet valves
- Manifold, pipe trench and cable trays
- Bund wall and secondary containment
- Stairways, roof handrails and access platforms
- Fuel-grade internal and external coatings
Truck Loading
Road tankers loaded fast and safeA dedicated loading pump feeds the overhead gantry, where each bay fills a road tanker through a metered loading arm. Earthing and bonding, automatic shut-off and interlocks protect every load.
What’s included
- Overhead gantry with loading arms or hoses
- Dedicated loading pump and motorised valve
- Flow meters and batch controllers
- Automatic shut-off and interlocks
- Earthing and bonding for every truck
- Spill containment and drip trays
- Platform, stairs and handrails under a roof


Vehicle Refuelling
Vehicles refuelled and recordedMetered dispensers under a steel canopy serve light vehicles and service trucks. They draw from the tank farm through an emergency shutdown valve, and the litres issued at each dispenser show on SCADA.
What’s included
- Metered dispensers, sized to your fleet
- Supply from the farm through an emergency shutdown valve
- Litres per dispenser shown on SCADA
- Steel canopy with lighting over the islands
- Fire extinguishers at the islands
- Spill containment and drainage
- Driver identification and authorisation, where required
Control Room
One screen runs the terminalThe MCC and the Siemens PLC and SCADA sit together in one air-conditioned control room. From one workstation the operator starts the pumps, opens and closes every motorised valve, and watches every level, flow and alarm. A panel-mounted HMI gives the same view at the MCC.


On screen, live
- Tank levels and high-high alarms
- Valve positions and interlocks
- Flow in litres per minute
- Litres issued per dispenser
- Pump status and run timers
- Remote and local operating modes
Head Office
Watch your fuel from head officeThe SCADA that runs the terminal also serves its data over a secure link, so your head office sees the same levels, flows and alarms as the operator on site.
Remote or local

Every pump and valve runs in Remote, from the SCADA workstation, or Local, at the panel. The mode shows on screen.
Control stays on site
The Siemens PLC keeps the terminal running if the head-office link drops. The link carries monitoring and reports, with access set by your IT policy.
What head office sees
- Stock level in every tank
- Flow on the unloading and loading lines
- Litres issued at each dispenser
- Alarm and event history

Fire Protection
Fire protection that starts itselfA pressurised hydrant ring main surrounds the tank farm. When a hydrant or monitor opens, the fire pumps start automatically, and the status of the whole fire system shows on SCADA with the rest of the terminal.
1Prevent
- High and high-high level alarms
- Overfill interlocks on tank inlets
- Earthing and bonding at loading points
- Automatic shut-off at the gantry
2Detect
