The Singapore
Naval Maintenance Base
|
Undertook a trial on three vessels involving the
monitoring of fuel consumption (usage per hour). Two vessels which
were known to have higher than normal fuel consumption recorded
savings of 20% and the third a saving of 15%.

Four gas turbines used for power generation on an oil rig. These
turbines burn 5 gallons per minute per engine when loaded. When a
De-Bug Unit was fitted: "... filter usage cost has dropped from
$8,000 per year to less than $1,000 per year. We satisfied with the
appearance of the fuel we have has no unscheduled engine shutdowns
due to clogged filters. The De-Bug Unit has performed as well as we
were told it would ..."

"In addition to these savings we are now using around 8%
less fuel. TMs is partly from better engine
economy and partly from reduced fuel wastage due to bacterial
contamination levels"

Rescue Vehicle Support Ship (DSESS) Kellie Chouest, leased
to the US Navy for research, rescue and retrieval, suffered severe
algae contamination and the fuel filters required replacement every
few hours. Installation of De-Bug units in the fuel supply lines
solved the problem and allowed filter replacement to be undertaken
at the normal servicing intervals.

Union
Rotorua |

A
merchant vessel operated by Union Shipping of New Zealand,
was supplied with over 1000 Tonnes of light marine diesel bunker oil
which was subsequently found to be contaminated with Hormonicus
Resinae. The bacteria caused severe problems by fouling fuel
filters; filter life was reduced from 6-8 weeks to 17 hours.
On fitting two De-Bug L4000 units, the fuel filter life was extended
such that frequent and expensive filter changes were no longer
required. The two units successfully coped with fuel flow rates of
78 tonnes of fuel every 24 hours. While cleaning of the infected
bunkers was still required, the fitting of the De-Bug units allowed
this to be scheduled for a convenient time, allowing the vessel to
continue a normal trading pattern and generating revenue for it
owners. No further problems were reported during the last five years
of service that were completed in 1998.

Ship Control Services |

A merchant vessel operated by Ship Control Services (PTE) Ltd. of
Singapore, had engine exhaust temperatures above the maximum
recommended levels.
An L4000 De-Bug unit was fitted which resulted in a reduction of
the engine exhaust temperature to within limits. In addition, daily
fuel oil consumption (for the same shaft revolutions) was reduced
from 17.4 metric tonnes to 15.5 metric tonnes.

Ray
Piper: |

From the first trip I
noticed a better engine performance. For the first time in my memory
the engines were pulling evenly. They were running cleaner and
quieter. There is no smoke at all. Before I had thick black smoke.
The engines are really sweet now, and the fuel is crystal clear.
Numerous people have commented on my clear fuel. The De-Bug has been
on my motors for a year now and I haven t had to change the filter
once.
I also have figures to
prove that I have greater fuel economy

The Port of Singapore |
|
Undertook a trial in one of its vessels and fitted a L1000 De-Bug unit
on one of the vessels engines. After fitting, the number of filter
changes reduced by 40% compared with the other engine. The other
engine was subsequently fitted with a De-Bug unit. |

High
Speed Catamarans |
Operating between Singapore and Malaysia frequently experienced main
engine and auxiliary engine stoppages due to heavily clogged water
separators and secondary fuel filters resulting from a jelly like
growth and the filters had to be replaced every three days.
The operator tried using fuel additives but found the cost
prohibitive. In addition to the blocked filters, the operator
experienced expensive damage to the fuel pumps and injectors.
Since installing a De-Bug unit, fuel oil filter elements did not
have to be changed within the first three months of operation, no
further damage was reported and fuel economy was improved.

Two
Korean trawlers |
|
Participated in a comparative trial from December 1995 to June 1996;
Trawlers #601 and #608, both were considered identical, except #608
had a De-Bug unit. fitted. The two trawlers left Korea the
same day to operate off the coast of Portland, Oregon, USA. Against
the background of similar operating hours and total loading on the
engines, the trial demonstrated:
1. Fuel saving of nearly 20%
2. Nozzle life per running engine increased on average by 25%

Tropic

"Our
engines are running cleaner with less down time for our clients and
we have reduced
our replacement of fuel filters by more than
half. We are also experiencing a reduction in our fuel consumption.

After using for
2 years
"...have
been using De-Bug Units for over two years on our extensive fleet of
yachts, generators, trucks and other vehicles" " ... with the use of
De-Bugs, we have increased our engine time between overhauls from
from 3000 to 4500 hrs with very little mechanical downtime..."

Inconnu, a 60ft fishing vessel |
Used for crab and lobster fishing off the Channel Islands
experienced fuel starvation due to filter blockage. The problem
became so severe that the filters were being replaced every day.
Treating the fuel with Biocide only increased filter life to two
days! Upon fitting a De-Bug unit, the contamination problem was
eradicated and filter life increased to 40 days. The owner also
dispensed with using expensive chemicals.

Norna
- Scottish Fisheries Protection Vessel |
|
Experienced microbial spoilage in the diesel fuel header tank, and
during bad weather, a build up of a sludge type biomass in the fuel
feed line to the purifier halving its capacity from 1 tonne per hour
to 0.5 tonnes per hour. In addition, the fuel strainers on the feed
lines to the twin 3,000 HP engines had to be cleaned every ten days
to prevent fuel starvation.
After fitting of an L4000 De-Bug Unit, restrictions were eliminated
and the cleaning cycle for the engine strainers was increased to ten
weeks; a sevenfold increase in life.

Prior to fitting the
De-Bug I was using abut 320 litres of diesel on the
Cairns - Townsville return run and since fitting the De-Bug
the same run is only using about 270
litres of fuel, representing a fuel saving of about 15%. |

Remote Power Stations in the Darwin |
Area of Australia are supplied by coastal barges which in many cases
cause the infestation of the diesel fuel used. The Power and Water
Authority of the Northern Territory fitted De-Bug units to the fuel
systems and recorded increases in fuel filter life from 168 hours to
500 hours. Further trials demonstrated that filter life could be
increased well beyond 500 hours.
