Reduce fuel costs by Blending your own fuel
The economy of a Power Plant is highly influenced by the oil prices. Even
running on Heavy Fuel Oil (Residual Fuel Oil) is becoming more expensive.
Fuel oil blending unit
The Go4 DN32 Flexblender is with the same attention to detail and
able to cut some of the cost
Fuel oil treatment units
and prevent catalytic impurities
from damaging the engine.
If, like most power plants, you buy
your HFO from an oil company or a
terminal, the price will be influenced
by several factors - chiefly the market price, but also the cost to blend
the viscosity you require, storage of
the finished product and risk.
Because, as a power plant you buy
large quantities, you can buy a very
heavy (high viscosity) HFO on the
open market and BLEND
it with a distillate (MGO/
MDO/ADO or the like)
and reach the exact viscosity you require.
Not all oils are created equal, as can
be seen from the International Organization for Standardization guidelines (ISO 8217) categorizing fuel oil
Despite these guidelines, there are
no clear definition of categories for
heavy fuel oils, marine diesel oils and
lubricating oils. Due to their density
and other properties, they represent
various process issues with regards
to separation.
At the other end of the scale are
lighter fuel oils, such as marine diesel oils and distillates.
For upstream oil operations, making use of locally available fuels to
generate the power required is a key
requirement, as facilities are often
located in remote onshore locations
or offshore with no or limited access
to an electricity grid system; and
transportation of large quantities of
expensive premium fuels to the site
location is problematic and uneconomic.
With the Go4 Fuel Blending System you remove
guesswork and uncertainty from the blending
The system is a scaled
down version of similar
systems used by professional fuel oil suppliers
around the world and
At one end of the scale are the residual oils or heavy fuel oils, with different densities and viscosities, which
may have harmful impurities. These
fuels require the highest separation
methods to ensure good separation
In between are a whole range of separation requirements.
Main Features
• Maximum reliability and safety
due to shell type heaters and
separate viscosity and temperature controllers
• Fast and easy installation due to
compact design
• Easy operation and maintenance
• Long life span and flawless operation due to the best components, carefully chosen materials
Fresh Water Generation
by distillation
Distillation is the oldest and most
commonly used method of desalination. Distillation is a phase separation
method whereby saline water is heated to produce water vapor, which is
then condensed to produce freshwater free of salts.
Technical Water or Potable Water Systems for installation in engine rooms
The PEV501SV converts seawater to
freshwater for domestic use, on ships
and rigs or at remote onshore locations. The system is able to produce up
to 50 tonnes of Fresh water per day.
Skid mounted including shell, water
ejector, distillate pump, ejector
pump, control panel, steam injector
and instrumentation.

Sanitary Water Heaters
To heat sanitary water on vessels
and platforms.
Heaters can include control panel
for resistances and circulation
pumps. Units can be supplied
loose or with all the elements installed in the same frame.
These are manufactured in stainless steel AISI-316L and with
thermal isolation in 50 mm mineral wool finished in stainless steel
Sanitary heaters are available for
heating through electric resistances, steam or hot water.
Models available with capacity
from 100 - 3000 litres.
Booster units
comply with international standards.
The fuel oil module is fitted between
the oil-transport line from the day
tank to the main engine. This allows
for a constant supply of heavy fuel
oil over pump systems.
The core of our systems is the viscosity measuring and control unit (Bunker Monitor System).
Heaters are used to reach the required viscosity. The control valves
and gauges are there for safety.
The components all need to work
well together - as the components
are the core of the engine room.
The blending process is simple
You purchase a higher viscosity Fuel
Oil e.g. IFO380 or 500 and mix it with
a low viscosity product (MGO/MDO/
Cutter Stock) to create the exact viscosity you need and in accordance
with ISO8217:2012.
The system is adapted for different
engine types providing the required
injection viscosity (e.g. 8 – 25 cSt)
and the corresponding temperature
(e.g. 90 – 150°C).
The Go4 fuel oil modules are used
for heavy fuel oil up to 700 cSt and

Fully Automatic System
The operation is constantly monitored
by a PLC that makes all necessary adjustements to the blender. (See Go4
Bunker Monitor for further information)
Can be combined with high/low level
sensors on the day-tank to re-fill when
Go4 Bunker Monitor
The control of quality parameters
like viscosity, density and temperature are fulfilled through the use of
the Go4 Fuel Monitor system which
ensures an optimal and consistent
quality to the exact ISO8217 product
specification throughout the entire
blending process.
The reference Viscosity is shown on
an LCD display where the Operator
can control the actual viscosity at reference temperature (50oC) and adjust
the blending ratio if required.
