Fuel, Lubrication & Gas-Fuel Systems

FO transfer & storage system

The tanks and transfer pumps that receive fuel at bunkering and move it between storage, settling and service tanks in the daily fuel routine.

FO purifiers

Centrifugal separators that spin water and dirt out of heavy fuel before it reaches the engines — essential because residual marine fuel is dirty by nature.

FO supply / booster units

The pump-and-heater module that delivers fuel to the engines at exactly the right pressure and temperature, circulating it continuously so injection viscosity stays correct.

FO heaters & viscosity control

Heaters and a viscosity controller that keep heavy fuel thin enough to inject properly; the controller adjusts heating automatically as fuel quality varies.

MGO cooling unit

A chiller for marine gas oil, needed because distillate fuel becomes too thin to lubricate fuel pumps when it gets warm in the engine room.

Fuel changeover system

Valves and controls that switch the engines between fuels — for example heavy fuel to low-sulphur gas oil before an emission control area — gradually, so thermal shock does not damage the injection equipment.

Bunker / FO flow metering

Flow meters, increasingly accurate mass-flow types, that measure fuel received and consumed — the evidence in bunker quantity disputes and the data source for emissions reporting.

Fuel gas supply system (FGSS) & GVU

The equipment that stores gas fuel and delivers it to the engines at the right pressure and temperature; the gas valve unit (GVU) is the final control-and-shutoff station before each engine.

Alternative-fuel containment and bunkering system

The special tanks and bunkering stations for a chosen alternative fuel, with the surrounding safety arrangements — the equipment package that a fuel decision brings aboard on any ship type.

Fuel gas venting & vent mast

Dedicated vent piping and a tall mast that release gas from fuel systems safely high above deck during operations or upsets.

N2 system for fuel installations

A nitrogen supply that purges and inerts gas-fuel piping and surrounding spaces, so lines can be opened for work without an explosive atmosphere.

LO purifiers

Centrifugal separators that continuously clean the engines' lubricating oil, removing water and combustion residues so the same oil charge can serve for years.

Main & camshaft LO systems

The pumps, coolers and piping that circulate lubricating oil through the main engine's bearings, keeping metal surfaces separated and carrying heat away.

LO automatic filtration

Self-cleaning filters in the lube oil line that trap particles and flush themselves without stopping the flow, protecting bearings between purifier passes.

Stern tube LO unit

The small circulation and header-tank system that lubricates the stern tube bearings and keeps the shaft seals pressurised against the sea.

Cylinder oil lubrication system

The separate once-through oil system of a two-stroke engine that injects fresh alkaline oil onto the cylinder walls, lubricating the piston and neutralising acids from the fuel's sulphur.

Methanol / low-flashpoint-liquid fuel supply system

The double-walled piping, leak detection and supply skid for methanol fuel, whose low flashpoint and toxicity demand containment beyond ordinary fuel practice.

Ammonia fuel supply system

The supply installation for ammonia fuel, built around its toxicity: double barriers, extensive gas detection, water screens and treatment of any vented gas.

Lubricating-oil transfer and storage system

The storage tanks and transfer pumps for the ship's stock of different lubricating oils, from delivery aboard to each machine's service tank.

Hydrogen fuel storage and supply system

Storage and supply for hydrogen fuel — deeply cold or highly compressed — with the leak detection and venting that the smallest and most escape-prone fuel molecule requires.
