Your Fleet is onlY creAtinG vAlue When it’s At seA, in
motion
To make sure that happens, it’s vital that fuel oil is kept in
prime condition, to keep engines running smoothly and efficiently,
and to ensure full compliance with environmental and operational
regulations.
This is a complex area. Inconsistency and degradation of fuel
quality can cause serious problems for ships. It can mean time lost
on the maintenance and repair of fuel and combustion systems. And
fuel that doesn’t burn efficiently will generate more carbon
emissions and result in negative impact on the environment.
Here’s where Wilhelmsen Ships Service (WSS) can help with a
range of fuel treatments to maintain the efficient running of your
vessels and reduce operating costs. Using Unitor fuel treatments
where required will improve fuel efficiency and prevent excess
mechanical wear caused by contaminants in the fuel. At the same
time, you’ll keep your vessels running in line with current
environmental regulations.
Several solutions, with a single aim: to keep your fleet on the
move.

The WSS product line offers a wide range of effective solutions
with minimal environmental impact. The treatments themselves are
manufactured according to ISO 9001 and ISO 14001 standards. We
offer a variety of fuel testing options for water content, density,
viscosity and compatibility that can be carried out during
bunkering. This allows crew to take immediate action if problems
are detected, reducing time in port and preventing further issues
developing down the line.
Our range of fuel treatments and additives has been designed
specifically to address the full spectrum of technical
challenges:
Fuel lubrIcIty Low sulphur fuels show reduced lubricity which
can lead to increased wear of pre-engine components such as
injectors and fuel pumps. The reduction of sulphur is often blamed
for the problems with lubricity, however lower sulphur content is
not the single cause. The refining process in which the sulphur is
removed also removes other natural lubrication components. This
means that fuels with similar sulphur levels can have different
lubrication properties.
DIesel Fuel stabIlItyMost distillate fuels are vulnerable to
degradation through a range of reactions. The result of fuel
degradation is colour change, gum formation and sedimentation. This
can have a severe effect on the long-term storage of fuels and can
also cause corrosion of the fuel system. The best protection for
the fuel is to add a fuel stabiliser during bunkering.
Heavy Fuel stabIlItyThe use of low sulphur fuels, especially in
Emission Control Areas (ECAs), has led to the production of more
blended fuels. But blending can cause incompatibility problems,
especially if the fuel is high in asphaltene. An unstable fuel oil
will cause excessive sludging, and subsequent filter and separator
problems.
IgnItIon anD combustIon QualIty The need to change or blend fuel
supplies to meet SOx emission regulations can also affect the
ignition and combustion characteristics of the fuel. Poor
combustion and ignition may lead to increased carbon deposits in
the engine. Excessive fouling of the scavenge air receiver combined
with late ignition or prolonged combustion may lead to a build up
of soot deposits and the risk of fire. For steam boilers poor
ignition quality may lead to starting problems and more frequent
flame failures.
DeposIt FormatIonIn heavy fuels there are contaminants in the
form of metals. These contaminants, especially the sodium and
vanadium, tend to form sticky materials that deposit on exhaust
valves and turbo chargers. These deposits are highly corrosive
which can attack the metal causing damage and failure. Formed
deposits also have a high insulating effect which reduces the
overall efficiency and increases the cost of running the
installation.

test kIts
Waiting in port for the test results of bunkered fuel costs time
and money. But sailing without them is a risk. test kits provided
by Wilhelmsen ships service let your technicians carry out fuel
analysis quickly and accurately, with rapid results. suitable both
for heavy and distillate fuels, our kits can be used to measure
water content, density, viscosity and compatibility. And where
problems are detected, these can often be remedied effectively by
the application of unitor fuel treatments.
eXHaust emIssIons controls
tighter controls over exhaust emissions have direct implications
for the specification of fuel oils. these regulations mean that
ships must switch fuels when entering and leaving regulated areas –
a situation that increases the likelihood of issues with fuel
compatibilty and the attendant problems of deposition, corrosion,
blockages and poor combustion. unitor testing and fuel treatments
help to prevent fuel problems and avoid further costs from
maintenance and repair.
