First North American Boat
Powered by Volvo Penta IPS
Thomas Paine, a new 50-ft. aluminum patrol
boat that joined the Massachusetts Environmental
Police fl eet in July, is the fi rst commercial vessel
in North America to be powered by Volvo Penta
IPS propulsion. Built by Metal Craft Marine Inc.,
the new boat is equipped with twin Volvo Penta
D11 510hp marine diesel engines driving IPS650
steerable drive units. The Volvo Penta IPS con-
sists of a steerable underwater drive unit with two
forward-facing counter-rotating propellers. The
drive units pull the boat rather than pushing it
through the water, thereby increasing effi ciency.
“We decided to install IPS instead of traditional
shafts in the new boat primarily because of its low-
er fuel consumption and extended cruising range,
allowing us to build the boat with a smaller fuel
tank, saving space and weight,” said Chris Baker,
acting director, Massachusetts Environmental Po-
lice. “Because the boat idles a lot on station, the
automatic DPS was another critical factor in the
decision to go with the Volvo Penta IPS.”

GreenSteam Optimizer
GreenSteam Optimizer is an onboard decision
support system that is an adaptive, data-driven so-
lution, helping the master to make the right deci-
sions. Achieving maximum fuel effi ciency means
operating at the most effi cient speed using as little
fuel as possible. The optimal settings and param-
eters such as trim, draft are a vital in setting up
the vessel, and depend on a range of conditions
such as load, waves, wind, water depth and many
other factors. By continually optimizing the trim
and draft of the vessel based on data collected
onboard the vessel, propulsion resistance is mini-
mized, saving fuel. The GreenSteam Optimizer is
compact and intuitive, simple to use and fi tting the
unit to existing vessels is simple and straightfor-
ward requiring no major modifi cation of the ship,
the developer said. Installation takes less than a
day if the cabling has been prepared. The system
consists of two small GreenSteam radars installed
in the bridge wings, and touch screen console
which connects to wind and fl ow meter sensors,
trim and the radars.

Mermaid Kohler Range Launched
The partnership between U.K. diesel engine
marinizer Mermaid Marine and Kohler expands
Poole based Mermaid Marine’s offering to small-
er inboard engines with the company now able to
supply engines from 31kW to 376kW.
It has come about through Mermaid Marine’s
parent company, Power Torque’s work with JCB
which has partnered with Kohler’s Global Power
Group to use the Italian manufactured engines
in several of its compact machine lines in what
the company terms the next stage of its engine
strategy. “The decision to partner with Kohler to
develop engines for JCB compact machines was
driven by the synergy in the technologies used by
JCB and Kohler to achieve stringent emissions
legislation,” said Alan Tolley, JCB’s director of
engine programs. The Mermaid Kohler mechani-
cal engine is marinized by Mermaid Marine and
meets the next stage of emissions targets without
the need for a diesel particulate fi lter. The engines
feature cylinder block with bed plate architecture,
a 4-valve cylinder head, gear driven valve train
and optimized direct injection (DI) fuel system.
The engines use direct injection technology and
are naturally aspirated with mechanical govern-
ing. The range currently comprises two engines,
the KDI 1903M three cylinder, 42hp / 31kW and
the KDI 2504M four cylinder 49hp / 36kW with
further developments planned in terms of options
and power ratings.

VSP for Norderney Ferry
Ferries operated by Norden-Frisia AG have
been serving the East Frisian island of Norderney
for decades. Navigation in these coastal waters
poses special challenges: in some areas the wa-
terway only leaves a few centimeters below the
keel and the water contains a signifi cant amount
of swirled-up sand. A new sister ship of the dou-
ble-ended ferry MS Frisia IV equipped with Voith
Schneider Propellers (VSP) is to enter service in
summer 2015. Norden-Frisia AG had already se-
lected a VSP propulsion system for the Frisia IV
which has been serving the route between Nord-
deich and Norderney since 2002. This propulsion
concept proved successful and will now also be
used for the new vessel.
The ferry will be built by the Cassens shipyard
in Emden. With a length of 74.3 m and a beam of
13.4 m, it will be slightly longer than her sister
ship. The newbuild with a draft of 1.75 m and is
designed to carry 1,340 passengers and 60 cars,
reaching a speed of eight knots in shallow wa-
ter and 12 knots in deeper water. Four type 16R5
EC/100-1 Voith Schneider Propellers will be used
for propulsion and maneuvering. The propulsion
concept is diesel-electric, and the VSPs are driv-
en by speed-controlled electromotors. Voith also
supplies bow tooth couplings connecting engine
and VSP, thus eliminating the need for intermedi-
ate gearboxes and additional shafts.
