Kvichak Marine Industries of
Seattle, Washington, U.S.A., has
recently launched the first of three
Camarc-designed, all-aluminum 22. 8
m overall pilot boats for Nederlands
Loodswegen — the Dutch Pilotage
Association (DPA). Camarc Design is a
British naval architecture group that
specializes in the design of fast, seaworthy workboats.
DPA is one of the busiest pilot associations in the world, serving Rotterdam’s busy port as well as smaller harbors along the coast of the Netherlands
— a coastal zone that has been declared
a “sulfur emissions control area” by the
European Union.
By specifying that the new pilot boats
should be fitted with the best-available
technology in marine diesel emission
control, the Port of Rotterdam is demon-

strating a proactive environmental role.
In addition to twin Cat C- 32 ACERT
diesels each rated at 969 k W that meet
EPA Tier- 2 (EU IW/CC2) standards, the
pilot boats are equipped with a
Nauticlean DeNOx system supplied by
Hug Engineering of Switzerland and
Soot Tech of the Netherlands.
Nauticlean’s “DeNOx” version is a
combined diesel particulate filter (DPF)
and selective catalytic reduction (SCR)
that is designed, manufactured and
marketed by Hug Engineering for 150
to 3000 k W marine applications. It is
certified by Lloyd’s Register of Shipping
and Germanischer Lloyd for both new
and retrofit applications. Hug builds
the entire system in-house — from the
metal containers to the ceramic filters.
Kvichak already had experience with
SCR technology, having built the hulls
for four 36 m catamaran ferries for the
San Francisco Bay Area’s Water
Emergency Transportation Authority
(WETA), (see D>W, November
2009). Kvichak installed all the
machinery in the catamarans’ hulls,
while partners Nichols Brothers Boat
Builders were responsible for the
superstructure, which included the
SCR system.
