bon-emission energy source, and ammonia, which is expected to be
utilized as a new fuel in low- and zerocarbon-emission societies. The vessel
is designed with increased cargo tankcapacity while maintaining the princi-

pal dimensions of LOA and beam similar to conventional vessels so that thecarrier can be berthed at major LPG
terminals around the world.
In consideration of the strengthening of environmental regulations
around the world and action plans for
the Sustainable Development Goals(SDGs), Kawasaki will continue todevelop and provide customers withenvironmentally-friendly ship technologies centered on LPG carriersand LPG/NH 3 carriers powered by
LPG, as well as other types of merchant vessels that comply with thelatest environmental regulations,
including liquefied hydrogen carriers, which is expected to act as anext-generation energy source. Consequently, Kawasaki will contributetoward the realization of low- andzero-carbon-emission societies.
This carrier is equipped with a
Kawasaki-MAN B&W 6G60MEC10.5- LGIP, an electronically controlled, LPG-injection marine diesel
engine (ME-LGIP engine). By utiliz-

ing LPG as fuel, sulfur oxide (SOx) andCO 2 emissions in exhaust gases canbe significantly reduced comparedwith ships running on conventional
marine fuel oil, enabling compliancewith SO x emission standards and
EEDI Phase 3
regulations.
The propulsion
system is compliant with nitrogen oxide (NO x)
Tier III requirements and utilizes EGR and SCR
equipment.
Therefore, thevessel is able totravel in NO x
emission control
areas (ECAs)
even when operating on conventional low-sulfur
fuel. Fuel consumption is
reduced throughthe inclusion of the Kawasaki RBS-F(Rudder Bulb System with Fins), theKawasaki SDS-F (Semi-Duct Systemwith contra Fins), and energy-saving
fins around the propeller.
The concept design for a systemthat utilizes ammonia as fuel on thisvessel has been approved by Nippon
Kaiji Kyokai (ClassNK). Therefore,
the ship design specifications can be
modified to enable the use of ammonia as fuel in the future.

JMU develops anti-fouling system for marine propellers
using weak electric current
Japan Marine United Corporation(JMU), in collaboration with IHI
Corporation’ s Corporate Research &Development Division, has developed
a propeller anti-fouling system thatutilizes the anti-fouling technology forsliding guides of floodgates using weakelectric current, which was devisedand developed by IHI Corporation.
By passing a weak electric current
between the anti-fouling target andthe electrode, an oxygen consumption
reaction occurs in the surface layer of
the anti-fouling target. This anti-fouling technology causes the surface
layer of the anti-fouling target to be ahypoxic environment due to the oxygen consumption reaction, making it
difficult for marine organisms toapproach the anti-fouling target.
When an electric current is applied,
metal components contained in theseawater are deposited as a film on
the propeller surface, so it is necessary to change the current conditions
to make it easier to remove the film.
To verify the effectiveness of theanti-fouling system, onboard tests
were conducted on a small vessel fora total of two years. The degrees offouling on the propeller were examined by comparing the fuel consumptions for the duration of one year forboth with and without the action of
the anti-fouling system. This con-firmed that the increase in fuel consumption due to fouling of the propeller can be greatly suppressed by theaction of the anti-fouling system,
although the film removal process isrequired.
Presently, JMU are planning toconduct tests on larger ships to verify
the effectiveness of the newly developed system on larger ships, with theaim of practical application to large
merchant ships.
This technological development
was carried out as a contract development project subsidized by the Japan
Ship Machinery andEquipment Association (JSMEA) and
The Nippon Foundation.
