Meeting Report on TIER III Service Experience presented
Jeppesen, Promotion Manager at MAN Diesel & Turbo Ltd. at the Greek Section’s Technical Meeting on December 8, 2016
At the fourth Greek Section meeting for the 2016-2017season on
December 8 a presentation was given by Mr. Michael Jeppesen, Promotion Manager at MAN
Diesel & Turbo Ltd, who started it by giving some background
information on the enforcement of TIER III regulation
on NOx emission in NECAs on January 1, 2016. Despite this development almost a
year ago he mentioned that most new vessels with two stroke diesel engines
coming out of the shipyards in 2016, 2017 or even later are TIER II vessels.
He attributed this inconsistency
to the high cost of TIER III compliant NOx abatement systems that make ship
owners delay their installations and avoid the extra expense as long as
possible by ordering vessels, which have been keel laid before December 2015. This
practice allows them to temporarily avoid the economic burden that results from
system installation without neglecting to be law-abiding since these ships have
to comply with TIER II.
He also pointed out
that unlike initial anticipation the TIER III implementation onboard vessels
has been much slower and as a result, the ramp up of the TIER III engine rooms
is also delayed by one - two years. This has resulted in a longer maturing
period for MDT to optimize the NOx abatement systems.
He also brought to audience’s attention
that even though MDT has been developing TIER III compliant technologies for
nearly a decade, a strong game changer came into the picture in 2014, when it
was concluded that starting from 2016 onwards all NECAs would also be
considered to SECAs worldwide. This implied that any vessel operating in the
NECA (U.S.A. waters) would be operating on low Sulphur fuel (or in rare cases
on HFO in combination with a SOx scrubber).
Under these circumstances MDT decided to
continue further development of NOx abatement systems on basis of low Sulphur
fuel in Q4 2014. The implications were extremely positive and led to MDT system
portfolio of low Sulphur (LS) Exhaust Gas Re-circulation (EGR), high pressure
(HP) SCR and low pressure (LP) SCR with optimized sizing and equipment
configuration at significantly lower cost than the first HFO based systems. Mr.
Jeppesen concluded his presentation by referring to future potentials.
A Q&A session succeeded the presentations, while during the
post-meeting reception attendees
had the chance to meet with representatives from all segments of maritime
industry, discuss and share their ideas.
The meeting was attended by forty-nine (49) members
including students and professionals and ten (10) non-members.
The meeting was broadcast to SNAME members worldwide. Almost
twenty (20) members attended it virtually.
