GEA Westfalia Separator FuelCoolingMaster

Safe engine running on low-sulphur fuels

Equipped for the FutureGEA Westfalia Separator FuelCoolingMaster – reliable viscosity adjustment for all distillates

High-sulphur heavy fuel oils are a thing of

the past

International regulatory bodies such as the IMO

(International Maritime Organization) have decided

to drastically reduce the sulphur fractions in ship‘s

fuels, in order to make shipping even more environ-

mentally friendly. From 2012, the sulphur content is

to be reduced worldwide, from the present day 4.5

to 3.5 percent, then from 2020 to 0.5 percent. More

stringent limits already exist for so-called sulphur

emission control areas (SECAs) such as the English

Channel, the North Sea and Baltic Sea and the coast

of California. Short-term extension of these SECA

zones to include the whole coast of the USA and the

complete Mediterranean is already being planned. In

practice, this means: ships have to change over from

standard heavy fuel oils (HFO), which do not fulfil

these requirements, to distillates such as low-sulphur

marine gas oil (MGO) or marine diesel oil (MDO).

Minimum viscosity

However, this changeover poses special requirements

for the fuel viscosity: it must not fall below the mini-

mum limit set by the manufacturers for safe engine

or boiler running. According to the standard, the

viscosity range of the distillates must be between

6.0 and 1.4 cSt at 40° C. With the GEA Westfalia

Separator FuelCoolingMaster, a cooling system has

been developed which always reliably ensures that the

viscosity never falls below the value of, for example,

2.0 cSt regardless of the quality of the gas or diesel

oil used. Equipped in this way, ships with the

GEA Westfalia Separator FuelCoolingMaster system

are already geared up for all present day and future

requirements regarding the use of low-sulphur fuels

and can be deployed worldwide with maximum

engine and boiler reliability.

Individual, economical, reliableFor newbuildings or as cost and space-saving retrofit systems

With the FuelCoolingMaster, GEA Westfalia

Separator Group has developed a fuel cooling

system with which the changeover from heavy oil to

marine gas oil, optionally with marine diesel oil as

an intermediate stage, without any damage to the

machinery, is possible at any time, with temperature

and viscosity reliably controlled – for both main and

auxiliary engines and for boilers.

In addition, the system can also be extended with

a chiller. Depending on the system configuration, it

is therefore possible to use the following coolants,

individually or combined:

• Cooling water

• Cold water

• Seawater

• Cooling water / cold water

• Seawater / cold water

Individual solutions with a guaranteed future

Apart from complete systems for newbuildings,

GEA Westfalia Separator Group is specialised in

providing cost and space-saving retrofit systems

based on a cooler and / or chiller as individual

solutions for ships already in service.

All GEA Westfalia Separator FuelCoolingMaster sys-

tem solutions offer shipping companies and ship oper-

ators the security of being ideally equipped and ready

for use of all current and future low-sulphur fuels

specified by IMO MARPOL.

When a ViscoBoosterUnit is retrofitted

with a FuelCoolingMaster, all the compo-

nents are first checked for MGO compati-

bility. Any necessary software modifica-

tions are easy to implement. The add-on

of the ViscoBoosterUnit requires mini-

mum changes, even the existing control

can usually continue to be used. The

system‘s configuration options allow for

all kinds of different type variations, from

manual to fully automatic.

Retrofitting another manufacturer‘s „Fuel

Oil Supply Unit“ with a FuelCooling-

Master is possible without any changes to

the existing system. The FuelCooling-

Master is connected between the two as an

independent change over/cooler module,

without the old unit, designed for heavy

oil, including the sensitive fuel pumps

coming into contact with the MGO.

Numerous options for individual adjust-

ments, e.g. viscosity monitoring and con-

sumption measurement, enabled tailor-

made solutions for every requirement.

The ViscoBoosterUnit with integrated

FuelCoolingMaster provides a compact

solution with complete process control on

only one skid – especially designed for

newbuildings. The fuel cooling system for

main taining the minimum viscosity has a

fully automatic, machine-protecting, HFO-

MGO or MGO-HFO change over switch,

with which the maximum temperature

change is two degrees per minute. It is

easy, fast and safe to control using an E40

touchpanel.
