Wärtsilä's Senitec bilge water system receive...

Wärtsilä Corporation, Trade & Technical Press release, 28 November
2008

Wärtsilä's groundbreaking Senitec sludge and bilge water treatment
system has received US Coast Guard (USCG) Type Approval. Tests have
confirmed the system's ability to remove oil in water levels to well
below required by the International Maritime Organisation.

Rigorous testing carried out by the USCG-approved SGS Institute
Fresenius in Germany, one of Europe's leading providers of
non-medical laboratory analysis, confirmed effluent discharges of
less than 1 parts per million (ppm) The requirement by International
Maritime organization is 15 ppm.

While Wärtsilä received the Bureau Veritas Type Approval last year
and intends soon to apply for ABS certification, a US Coast Guard
certificate, means the American market is now fully open for Wärtsilä
to promote the Senitec system. The Senitec sludge and bilge water
treatment system has already been installed in 80 different
applications, 40 of which are marine-related.

Contribution to the environment

"It is a very hard test, and the Senitec system came through it with
flying colours," says Magnus Gripenwald, Wärtsilä Senitec project
manager, who oversaw the tests. "Even when using an emulsified
concoction of heavy fuel oil, diesel, iron oxides and detergent, the
outcome was the same. Furthermore, we have found that efficiency does
not reduce, even after years of running the system. This is a
contribution to the environment."

Dr Ulrich Hilverkus, the SGS Institute Fresenius official who
conducted the tests on behalf of the USCG, confirmed the performance
of the system. "The tests were performed successfully with all oil
content measurement results being less than 1 ppm. The equipment as
tested therefore meets and exceeds the Marine Environmental
Protection Committee (MEPC) 107 (49) requirements."

USCG Type Approval tests are widely considered to be the most
stringent, and are therefore considered as being the most valuable
Type Approval certificate to hold. The trials are more extensive than
others, and include assessments of a system's robustness, while the
electrical and electronic systems are tested at peak frequencies for
four continuous hours, far in excess of other approval trials.

Under the supervision of SGS Institute personnel, two Senitec units
were installed at the Wärtsilä Sweden facility to facilitate testing
of a range of capacities. A 500 to 1000 litre/h capacity unit, and a
larger 1500 to 2500 litre/h capacity system, were both tested over a
seventy-hour period.

Tilting of the units, to simulate a vessel listing at a 22.5 degree
angle, also produced results below 1ppm. In fact, even before the
oily water passed through the unit's fourth stage activated carbon
filtration process, the effluent discharged was only 3 ppm, still
lower than the 5 ppm limit required of vessels operating in
environmentally sensitive areas.
