Mitsubishi Heavy Industries (MHI) has
completed the conceptual design of
the “MALS14000CS,” a New Panamax
size 14,000TEU container vessel that
will contribute to the prevention of
The MALS-14000CS adopts the
company’s proprietary “Mitsubishi Air
Lubrication System” (MALS), which
reduces frictional resistance between the
vessel hull and seawater using air bubbles
at the vessel bottom. Incorporating the
MALS technology, along with today’s
most advanced high-efficiency ship hull
design and propulsion system, the vessel
will be capable of reducing emissions of
carbon dioxide (CO2), a major greenhouse
gas (GHG), by 35 percent compared with
container carriers of conventional design,
according to MHI.
MHI has already installed MALS on the
‘Yamatai’, a module carrier operated by
NYK-Hinode Line, a subsidiary of Nippon
Yusen Kaisha (NYK Line), and is verifying
its CO2 reduction efficiency, expecting
approximately ten percent cuts. This
marked the world’s first application of an
air-blow type ALS system on an
ocean-going vessel for permanent use; the
MALS-14000CS is the second application
of MALS technology.
The MALS-I4000CS is designed to
realize a ten percent reduction in CO2
emissions through the MALS technology.
The ship design, featuring a new
high-performance hull form, places the
bridge relatively forward, exhaust funnels
at the stern and additional container
space under the accommodation quarter.
The new ship design, providing increased
container carrying capacity, coupled with
a two-engine, two-shaft propulsion
system, enables a reduction in CO2
emissions by 24 percent, according to
MHI. Combined with another five percent
reduction enabled by the electronically
controlled diesel engine and waste heat
recovery system, the MALS-14000CS
achieves an overall 35 percent cut in CO2
emissions. The MALS-14000CS is designed
to be further environmentally friendly
through installation of an SOx scrubber to
remove sulfur oxide (SOx) from flue gas
and a ballast water treatment system.
Presently, as part of measures to
prevent global warming, CO2 emissions
reduction is strongly sought in the area of
international maritime transportation,
and the International Maritime
Organization (IMO) has been preparing
the framework of a CO2 emissions
convention. Against this backdrop, the
MALS-14000CS, by integrating marine-use
CO2 reduction technologies that are both
efficient and commercially viable, is
expected to contribute significantly to
global warming prevention.
MHI has stated that it will continue to
accord priority to the development of
vessels addressing CO2 reduction needs by
focusing on development of its “Eco-ship”
and expansion of applications to include
other ship types, leveraging its strength in
handling ships and major marine-use
machinery as well as the company’s
leading-edge technologies in energy-saving
and environment related areas.

Advanced Polymer Coatings’ MarineLine 784 cargo tank
coating system, already considered the pre-eminent coating
for chemical tankers, is becoming an important factor in new
“There is a growing market need for product tankers to carry
the expanding group of cargoes such as clean petroleum products
(CPPs), bio fuels, vegetable oils, and methanol,” said Donald J.
Keehan, Chairman of Advanced Polymer Coatings. “In addition,
new regulations for coating tankers carrying oil and dirty
petroleum products (DPPs) has also increased interest in
MarineLine for these uses.
To date, MarineLine 784 has been used on more than 300
chemical tankers worldwide handling a wide range of aggressive
chemical cargoes. MarineLine 784 uses forced hot air heat to cure
its coating. This creates a nearly impermeable coating barrier, thus
ensuring product purity from port to port. The ship can carry any
cargo immediately after leaving the shipyard, an added bonus.
A key benefit of MarineLine and its extremely smooth and
hard surface is that the tank cleaning process goes faster. Because
the coating is virtually absorbent-free with low surface energy,
less cleaning chemicals are needed, thus less slops are created.
There are also fewer limitations than conventional coatings and
stainless steel tanks. This gives the shipowner the opportunity to
carry a wide range of profitable cargoes without worrying about
the previous cargo residue contaminating the next cargo.
Mr. Keehan says that since its inception, MarineLine has never
had an insurance claim made regarding purity, a testimony to the
ease of tank cleaning and non-absorption of the cargoes carried.
According to Advanced Polymer Coatings (APC), MarineLine
784 offers much better performance and versatility than
conventional phenolic epoxy or zinc silicate linings, and now, it
will be at a cost comparable to conventional coatings.
“The reason we have been able to lower our costs for
customers is that within the past year, APC has revised and
streamlined its patented polymer manufacturing operation,”
according to Mr. Keehan. “Previously we employed outside
chemical companies to toll-manufacture certain elements of the
polymer that serve as a mainstay in the manufacturing of the
MarineLine coating. Now these various tasks are done in-house,
thus reducing our cost exposure. This will now enable more
shipowners and shipyards to specify MarineLine as the product
of choice. We have taken a very competitive pricing stance versus
other coatings, while providing a superior product.”
