1. Fuel Oil Handling System (FOHS)

Thermo System undertakes complete Design, Engineering, Supply, Fabrication, Installation, Erection, Testing & Commissioning of FOHS for different type of fuels (HFO, HSD, LDO, Naphtha etc) to be stored. Complete mechanical, electrical and engineering jobs are covered.

Typical Fuel Oil Handling System consists of unloading hose, decanting and transfer facilities, pumping and heating unit (if applicable), bulk storage tank, day tank and the process utility piping.

2. Unloading Skid

Used for unloading the fuel from tankers / wagons through hoses

A typical unloading skid consists of

Suction strainers

Pumps with drives

Instrumentation (pressure, temperature & flow)

Interconnecting piping with valves mounted on a common base frame

3. Bulk Storage Tank

Designed to API 650 and IS 803 standards to accommodate the Fuel Oil unloaded from tankers / wagons. These can be vertical fixed / floating roof tanks with material of construction of SS 316 / SS304 / Carbon steel.

A typical storage tank consists of

Electrical / steam heaters

Flame and lightings arresters

Breather valves

Instrumentation (level and temperature)

Thermal insulation

4. Transfer Skid

Used for transferring the fuel from storage tanks to the day tanks

A typical transfer skid consists of

suction strainers

pumps with drives

instrumentation (pressure, termperature & flow)

interconnecting piping with valves

inline heaters on the pump discharge line mounted on a common base frame.

5. Daily Tanks

Designed to accommodate the day’s requirement of fuel and located near the utility point.

6. Pumping & Heating (PHF) Unit

PHF unit is used to transfer the fuel from day tanks to the utility point i.e. boiler firing, furnace firing, engine etc at a required pressure, temperature & flowrate.

A typical PHF unit consists of

Inline Heater.

Instrumentation (pressure, temperature, flow, viscosity etc)

Pressure regulating / control valves

The balance scope as described in the transfer skid.

7. Piping

The total process utility piping (CS/SS) - starting from unloading point to utility point along with the necessary accessories and instrumentation.

8. Electrical control system

This comprises of power distribution from control instruments like RTDs, thermostats etc. for control and monitoring of various parameters in the system.

This can be classified as follows 

Control panels ( PCC/ MCC/ LCP/ PLC, Instrumentation panels)

Power, control and instrumentation casing

Cable tray, earthing etc.
