Kawasaki Shipbuilding Corporation has completed the 182,534DWT bulk carrier, CAPE YAMABUKI (HN: 1633), at the Sakaide Shipyard. The vessel is the third of 180,000DWT series newly developed by Kawasaki and has a maximized cargo loading capacity within the ship size permitted to enter the Port of Dunkerque, France. The CAPE CANARY adopts the Common Structural Rule (CSR) of the hull structural strength required for bulk carriers to increase safety of the vessel. Total energy saving of the vessel is achieved by installing a fuel-saving main diesel engine combined with a highly efficient propeller, the Kawasaki SDS-F (Semi-Duct System with contra Fins), and the Kawasaki RBS-F (Rudder Bulb System with Fins). With such increased propulsion efficiency, the fuel consumption of the main engine is drastically decreased. The fuel oil tanks are double hull construction, and the deck machinery is directly operated by electric power dispensing with hydraulic oil. Therefore, the possibility of accidental marine pollution is decreased in the event of collision or damage. The Performance Standard for Protective Coatings (PSPC) is also applied for the improvement of quality of coatings, which provides preventive measures against corrosion of the ballast water tanks.

Imabari Shipbuilding Co., Ltd. has completed the Hokuren Maru (HN: 604), a 13,950GT roll-on/roll-off cargo carrier, for a Japanese domestic owner at its Imabari Works. The Hokuren Maru employs a new design developed for high-speed vessels with a new navigation system by Imabari based on safety and environmentally friendly concepts. The ship is now operating between Kushiro, Hokkaido, and Hitachi, Ibaraki Pref. This is the first of two sister vessels, which are replacements for predecessors. Due to the increase in car cargo transportation, the sizes have increased over the former vessels as seen in the table below. The Hokuren Maru has four car loading decks, and two rampway doors (drive-through access) are suitably installed at the fore and the stern of the starboard side of “B” deck. The chassis can load from the rampways of “B” deck into the designated positions in the areas of “A,” “B” and “C” decks through hinged-type slope ways. The passenger cars can be accommodated in the same way to “C” and to “D” decks through hinged type and fixed type slope ways. The car loading deck “B” is designed with completely non-pillar construction for efficiently loading and unloading cars, and other decks also employ the non-pillar design except the areas around the slope ways. The non-pillar construction facilitates not only chassis roll-on/roll-off work but also general passenger car maneuver. Ship maneuverability in both ports has become easier with one bow thruster and two stern thrusters.

Sanoyas Hishino Meisho Corp. has completed construction of the 4,350,000cf woodchip carrier, Crossandra, for the delivery to Cygnet Bulk Carriers S.A. (Panama) at the Mizushima Works and Shipyard on Nov. 27, 2009. The vessel is the 4th of the series of the newly developed SANOYAS 4.35 million cubic feet (approximately 123,000m3) type woodchip carriers, making it one of the largest cargo hold capacities in the world. The Crossandra is the flush decker type with aft engine room and accommodation house. The cargo space is divided into six holds, each structure of which is designed and arranged for efficient loading and unloading of woodchips. The vessel has greater depth than that of the conventional bulk carrier of the same deadweight class due to its design to carry low density cargo like woodchips. For increased propulsion efficiency, the vessel is equipped with a lowspeed and long-stroke main engine combined with a high-efficiency propeller. Moreover, it employs SANOYAS developed energy saving device “STF” (Sanoyas-Tandem-Fin (patent): max. 6% energy saving and excellent cost performance with simple structure) on the stern shell. These devices contribute to the reduction of CO2 emissions.

IHI Marine United Inc has delivered the 499 g.t. chemical tanker for coastal sailing, Houwa-Maru. The owner of the tanker is well known Japanese company Shokuyu Tanker Co. The tanker is equipped with the electric motor driven propulsion system using IHIMU’s proprietary technology CRP (contra-rotating propeller). Based on superior shipbuilding technology gained through many years of experience, IHIMU has developed the most efficient electric motor driven system combined with CRP and the efficient hull form. This system is competitive with fuel oil propulsion, contributing to the environmental protection with reduction of NOX and CO2 emissions. The Houwa-Maru has reliable and flexible operation as the CRP is driven with two independent motors. Should one of the propulsion systems or motor be damaged or fail accidentally, the other propulsion system will be sufficient to maintain the ship’s operation. Since the CRP electric motor system is free from the barred range of the diesel engine, ship maneuver in a port is facilitated. Depending on electric demand for ship’s operation (normal running, loading/unloading, drifting, etc.), the ship crew can select the number of the running diesel generators, which will further reduce fuel consumption.
