Provenance

Since year 2010 MERGI PFT catalyst has been in constant use on vessels in our fleet. The following effects have been on M/F “Wawel”, IMO: 7814462:

– Soot emission drop (in accordance to TUV By RgG 233) by 42% on main engines, heavy fuel.
– Soot emission drop (in accordance to TUV By RgG 233) by 33% on auxiliary engines, heavy fuel.
– Nitric oxides (NOx) emissjon drop by 10% on main engines, heavy fuel.
– Nitric oxides (NOx) emissjon drop by 13% on auxiliary engines, heavy fuel.
– Nitric oxides (NOx) emissjon drop by 38% on auxiliary engines, light fuel.
– Carbon monoxide (CO) emission drop by 13% on main engines, heavy fuel.
– Carbon monoxide (CO) emission drop by 13% on auxiliary engines, heavy fuel.

MERGI PFT effects on maintenance, as observed by Polferries crews:

– During piston ring change on one of the heavy fuel auxiliary engines, no soot or other residues were found on the ring, ring grooves or on the piston. This was contrary to pre-Mergi experience. The maintenance interval was several montsh, and heavy pollution was expected.
– At routine valve inspection on one of the main engines, no deposits or sediments were found on the valves and inlets, where a large a- mount of contamination was expected due to long period since last overhaul.
– Significantly extended lifecycle of injector nozzles was found. Lifetime extended from 8.000-9.000 working hours to 12.000-13.000 working hours.

Catalyst dosing was carried out in an automated manner, with a minimum participation of crews, limited to refilling the Mergi dosing tank when required.

MERGI PFT is now being used on all Polferries vessels.

DEAR MR. SOERENSEN:

I REFER TO YOUR E-MAIL FROM NOVEMBER, AND I AM SORRY FOR THIS LATE REPLY CAUSED BY EXTENSIVE TRAVELLING –

AS YOU KNOW WE HAVE BEEN USING MERGI ON ” DAGHILD ” SINCE 1992 AND ON ” ELBE ORE ” SINCE 1996 – AS FOR YOUR SPECIFIC QUESTIONS, I HAVE NO TIME TO RUN THROUGH ALL PAST REPORTS, BUT THE PROOF IS IN THE PUDDING WHEN IT COMES TO MERGI – IF WE HAD NOT EXPERIENCED
INCREASED EFFICIENCY OF OUR ENGINES, WE WOULD NOT HAVE CONTINUED TO USE THE EXPENSIVE MERGI – 

I ATTACH ” OBJECTIVE EVIDENCE ” SHEET FOR OUR TWO VESSELS FOR 1998-1999-2000-2001 ( OUR COMPLIANCE OF THE ISWM CODE ) –

PLEASE BE ADVISED THAT WE HAVE NOT DONE ANY GRITBLASTING OR COATING OF THE UNDERWATER HULL OF “
DAGHILD ” SINCE 1994, THAT IS BOTTOM AND UP TO 9 METRES DRAFT – OUR PAINT SUPPLIER IS CRYING – THE FACT IS
THAT WE HAVE OPERATED FOR ALMOST
8 YEARS WITHOUT TREATING THE UNDERWATER HULL – FURTHERMORE, WE HAVE INCREASED THE RPM FROM 85 TO 99 DURING THE SAME PERIOD – WHEN WE PURCHASED THE ” DAGHILD ” IN 1990, HER SPEED WAS 13.5 IN BALLAST AND 12.5 LOADED, DAILY CONSUMPTION 
56 MT – BEARING IN MIND WIND,SEA CONDITION AND CURRENT, I ESTIMATE THAT WE HAVE REDUCED THE DAILY
CONSUMPTION ABT
3 MT PER DAY –

OUR OVERHAULING FREQUENCY OF CYLINDERS IS 8000 HRS, AND WE HAVE FOR SAFETY REASONS NOT INCREASED THIS
TIME LIMIT – HOWEVER, WE HAVE NOTICED HEAVY READUCED TIME FOR OVERHAULING, AND THE CREW NOW NORMALLY
DO A FULL CYLINDER JOB IN LESS THAN 8 HOURS – THIS IS PULLING OUT THE PISTON, CLEAN ALL COMPONENTS AND REASSEMBLE EVERYTHING – THE MERGI
EFFECT ON DEPOSITS ARE VERY NOTICEABLE AS FOR THE TURBOCHARGERS, THE HAVE ONLY BEEN OPENED UP EVERY 5 YEARS FOR REPLACEMENT OF BEARINGS AND CONTINUOUS MACHINE SURVEY BY CLASS –
5 YEARS FOR

AS FOR THE ” ELBE ORE ” SHE WAS RUNNING 11 KNOTS LOADED AND 12 KNOTS BALLASTED WHEN WE PURCHASED THE
VESSEL IN 1996 WITH A CONSUMPTION OF 55 MT FUEL – OBJECTIVE EVIDENCE SHOWS THE SITUATION OVER THE LAST
4 YEARS – OBJECTIVE EVIDENCE IS ON YOUR FAX MACHINE

I HOPE THE ABOVE IS USABLE TO YOU

BEST REGARDS
