Imabari develops Aero-Citadel superstructure for energy saving

95,000DWT bulk carrier, RAGA
Imabari Shipbuilding Co., Ltd. has completed the unique
95,000DWT bulk carrier, RAGA (HN: S-1590), at the
Marugame Shipyard. This bulk carrier has adopted a nextgeneration superstructure called the ‘Aero-Citadel’ withboth reduced air resistance effect and anti-piracy measures.
The Aero-Citadel has slimly streamlined shape and includes the accommodation quarters, engine room, and funnel casing. This slender superstructure can reduce the windpressure during navigation by 25-30% based on wind tunnel testing. For example, a Capesize bulk carrier navigating at normal output against about 9m/sec head wind
(Beaufort 5 class) will have fuel consumption decreased
by 2%. Moreover, the new design incorporates marine use
LED lighting in the accommodation and engine room lighting systems, which reduces the electric power required forlighting by about 50%.
The citadel concept has increased the safety and security of the ship. The slim, streamlined shape facilitates
turning of the bow of the ship toward windward during
anchorage and decreases the risk of anchor dragging. Allstairs are placed inside the superstructure as an anti-piracy measure. The entrance on the lower level deck has
thick reinforced steel doors. The accommodation windows

are bulletproof, and water cannons are placed on the upper deck to prevent pirate incursions into the accommodation. A citadel facility is provided as a refuge area in the
superstructure that can accommodate all the crew for several days, protected by double-layer security doors. The
facility is also equipped with communication devices us(Continued on Page 2)

PanamaJMU completes new 97,000 DWT coal carrier with CRP system
SHOYOH is the first eco-designed
coal carrier built by the Kure Shipyardof Japan Marine United Corporation(JMU). SHOYOH is designed mainly
for carrying thermal coal to coal-fired
power stations in Japan. Particulars
and specifications of the vessel are optimized for Japan’s port conditions.
The vessel can achieve high fuel-efficiency as well as safer and easier operation with the following technologies.
The contra-rotating propeller (CRP)
system for high propulsion performance which consists of two contrarotating propellers positioned in tandem. The aft propeller recovers wasteenergy from the rotating flow inducedby the fore propeller and changes thisenergy to thrust. Since the first application to a 37,000DWT bulk carrier in
1989, JMU has installed CRP systems
on over 20 vessels. For further improvement of the propeller efficiency, CRP
of SHOYOH has tip raked geometries.
Additional energy saving devices
include a semicircular duct and rudder bulb fitted before and behind thepropellers, respectively. The semicircular duct generates thrust and increases the wake gain by guiding
slower flow to the propeller disc. The
rudder bulb streamlines the flow andreduces separation losses from the propeller hub.
The exhaustgas power turbine generator(PTG) for saving
fuel consumption
during the voyage bypasses
some exhaust gasof the main engine to a gas
power turbine forgenerating electricity and saves
fuel consumptionof the diesel generator.
The center water ballast tank is arranged amidships for exclusive use
under heavy ballast conditions to eliminate the need for floodable hold(s).
Complete separation of water ballast
tanks and cargo holds helps for safer
and easier ballast water loading andunloading operations, prevention ofhold structure corrosion by seawater,and easier maintenance during voyage.
The vessel has been designed andbuilt under the survey of ClassNK in
accordance with IACS Common
Structural Rules for Bulk Carriers(CSR-B). SHOYOH has BC-B notation, which enables the vessel to load
not only coal, but also heavy cargoes,such as iron ore with homogeneous
loading in all cargo holds.

Kawasaki develops exhaust gas recovery system
K-GET for reduction of CO2 emissions
Kawasaki Heavy Industries, Ltd.
has developed an exhaust gas recovery
system K-GET (Kawasaki Green Eco
Turbine) for marine diesel engines,
which helps reduce CO2 emissions. Vessels engaged in international marinetransport will be obliged by the IMO
regulations to reduce emissions of CO2
from marine main diesel engines. Asan effective measure for IMO regulations, Kawasaki has continued to develop an exhaust gas recovery system
to make effective use of surplus energyof marine main diesel engines.
The exhaust gas from a main diesel
engine has so far been used to power
the turbochargers of the main diesel
engine for supercharging fresh air to theengine. However, the supercharging
system has greatly been improved
based on recent technological advances,
so requires less use of exhaust gas forthe supercharging system.
The K-GET system obtains a portionof the exhaust gas that bypasses theturbochargers and drives a power turbine. The force of the power turbine
assists the crankshaft of the main engine. The K-GET system uses
Kawasaki’s own power turbine to attain high power performance withsimple machinery design and arrangement, which minimizes the effect on themachinery room arrangement. By using recovered energy from the engine
exhaust gas as a part of the propulsion
force directly, the K-GET system candecrease the quantity of CO2 emission
and fuel consumption, and is usable forvessels such as bulk carriers and tankers, which have less demand for inboard
electricity during navigation.
Trial evaluations of the K-GET system carried out at the Kawasaki’s Kobe

Works confirmed that the system could
contribute to a 4% decrease in CO2emissions and fuel consumption. Kawasaki will continue to conduct sea trials on the system mounted on an actual vessel to evaluate its performanceand confirm durability. The K-GET system is scheduled to be marketed in2015.

Sanoyas completes Panamax bulk carrier, FORTE DE SAO JOSE
Sanoyas Shipbuilding Corporationdelivered the 78,384DWT Panamax
bulk carrier, FORTE DE SAO JOSE
(HN: 1308), to its owner, Empresa De
Navegacao Elcano, S.A., on July 2,
2013. The carrier built at theMizushima Shipyard is the 10th vessel of the 78,000DWT type Panamax
bulk carriers developed by Sanoyas.
The carrier has larger deadweight andcargo hold capacity than the conventional bulker. This is achieved by elongating the length between perpendiculars without changing the overall
length and beam. This vessel applies
the “Common Structural Rules” (CSR)of the International Association ofClassification Societies.
For improvement of propulsion efficiency, the vessel is equipped with alow-speed and long-stroke main engine combined with a high-efficiency
propeller and STF (Sanoyas-TandemFin (patent): max. 6% energy saving)on stern shell, which also contributeto the reduction of CO2 emissions. For
efficient cargo handling, cargo hatches
are widened as much as possible.
Dedicated fresh water tanks are provided for storing hold-washing water
generated by a large capacity typefresh water generator. In addition, a
special fuel oil heating system is applied to the fuel oil storage tanks inorder to avoid cargo damage by overheating and to save steam consumption. For protection of the environment, various countermeasures areincorporated, which include fuel oil
tanks of double hull structures, holding tank for accommodation discharges and dirty hold bilge, and independent bilge segregation system
for the engine room.
