CLEAN AND GREEN
Jelle Westerhof looks at the five top reasons why you need
Emigreen exhaust after treatment onboard your yacht
In the age of global warming, climate change
and plastic pollution, now is the time to
be evaluating the industry’s efforts in
being efficient and sustainable. The ways
to earn the accolade of being ‘green’ are
many and varied - but one easy solution
is to ‘Clean’ exhausts and emissions. As
the International Maritime Organization
(IMO) is actively working to reduce vessel
waste, new legislations are changing the
way superyachts are being built.
More often than not, new-builds will now
include a Diesel Particulate Filter (DPF)
and/or a Selective Catalytic Reduction
(SCR) system. These future-proof systems
eliminate 98% of expelled soot, reduce NOx
to below IMO Tier III levels and reduce noise
by up to 45dB(A). As this state-of-the-art
technology becomes an essential asset in
the engine room, we look at how the exhaust
gas after-treatment systems from Emigreen
actually work.
By catching 98% of the visible particles
A DPF exhaust gas cleaning system ensures
that no carbon particles are left on the deck
or in the surrounding waters. With their
next-generation systems, Emigreen has
made a compact and reliable solution with
various options to incorporate SCR and DPF
systems either together or independently
into one silencer housing.
A vacuum cleaner and compressed
air work together
On the rare occasion the elements need to
be outed from the structure, the mounting
frame is simply lifted out of the housing. To
ensure that the superyacht can keep cruising
with noise reduction in place, the solution can
be supplied with additional acoustic elements.
The SCR and the DPF system are integrated in
a high performance exhaust silencer
They can be controlled on a user-level base
by a touch screen in the engine room and
monitored remotely on the bridge. This is
where simple settings such as a forced
regeneration can be used to pre-schedule ash
removals. Whatever the preferred method,
Emigreen can tailor the system to suit the
project at hand.
The solution can fit any yacht project
Whether it be for a refit or a new-build,
a system can be incorporated into the
design at any stage. Emigreen’s aftertreatment
systems are custom designed
to merge seamlessly into any engine room;
as proven on board one of the world’s largest
sailing superyachts, which features four of
the systems. Here, the yacht’s general
arrangement instantly benefited as the
compact system requires only a bit more
space than the silencer in the engine room.
Plus, the system works in replacement of
the yacht’s silencer which also frees up
space and lessens the load.
Growing a positive reputation
Owners and their teams can play their part
and install more eco-friendly innovations
onboard. As more and more ports opt to
keep yachts without exhaust gas cleaning
systems anchored outside, get ahead of
the game and find out exactly how one can
be installed on your superyacht.
