46 Maritime Reporter & Engineering News ? DECEMBER 2013 World?s Largest Chemical Tanker Bow Pioneer was built for Odfjell SE by Daewoo Shipbuilding & Marine Engineering, designed with two longitudinal corrugated bulkheads with lower stools and transverse corrugated bulkheads with lower stools to have 10 sets (P&S&C) of cargo tanks, and 11 tanks for WB consisting of four pairs of wing and double bot- tom tanks, one U-type tank and two water ballast heel-ing tanks. The ship is equipped with a cargo handling system for the loading, storage and discharging of the intended cargos of IBC ship type 2 & 3 with typical cargoes such as Methanol, Vegetable Oils, MEG (Mono Ethylene Glycol), EDC (Ethylene DiChloride), MTBE (Methyl Tert-Butyl Ether), Xylene, Toluene, Cyclohex- ane, etc., as well as reÞ ned petroleum products (prod- ucts with ß ash point below 60 deg-C). The ship has a continuous upper deck with forecastle, a raked stem with a bulbous bow, a transom stern with open water type stern frame, a balanced spade rudder with ß ap and a Þ xed pitch propeller directly driven by MAN B&W 5S60MC-C8 engine with maximum rating of 10,870 kW at 103.7 rpm. Double side and double bottom are provided in cargo area and the volume of each cargo tank not to exceed 3,000 cu. m. The deadweight of the vessel will be 75,000 metric tons at the design draft of 13.2 m, without trim, with the vessel aß oat in SW with SG of 1.025, and 81,200 metric tons at the scantling draft of 14 m. The speed of the ship is 14 knots at the designed draft of 13.2 m on even keel at 85% MCR. The vessel is trimmed with Inorganic Zinc Silicate coat- ing for cargo and slop tanks, and stainless steel pipes for cargo related systems. Thirty-one cargo manifolds are arranged on the port and STBD sides with two tiers at the middle length of the ship. One raised catwalk is arranged from the front of the accommodation to mani-fold platform area and to forecastle deck on the upper deck.

It is the 14th product tanker that the shipyard has completed and the 18th vessel overall. It is 600 feet long and has a cargo capacity of 46,000 dwt. The ship is expected to be placed into service moving do-mestic oil to U.S. based reÞ neries. Name Wuchang Type Bulk Carrier Shipbuilder China Navigation Shipowner Chengxi Shipyard China Navigation Company (CNCo) took delivery of MV Wuchang, Þ rst of the 39,000 dwt B.Delta37 bulk carriers of Deltamarin design built under Lloyd?s Register?s approval and survey at Chengxi Shipyard in China. Deltamarin?s B.Delta37 design has attracted attention due to its performance, in terms of a range of parameters such as low fuel oil consumption, low emissions, EEDI, deadweight intake and lightweight particulars. On top of this, the vessel is designed to have excellent maneuverability and performance in heavy seas, as experienced during the sea trials. This is achieved through an optimized, energy ef Þ cient design, with particular focus on optimal hydrody-namic performance and lowest possible lightweight, without compromising either the cargo intake nor the hull structural integrity. Detailed structural Þ nite element analysis and fatigue design assessments, in accordance with IACS? Common Structural Rules, have been used to verify the hull structural integrity. The design characteristics have been validated dur- ing the inclining experiment and sea-trial conducted prior to delivery. Although Wuchang was contracted prior to the EEDI requirement coming into force Jan-uary 1, 2013, CNCo and Deltamarin requested EEDI veriÞ cation on a voluntary basis from LR. Accord- ingly, the EEDI value has been calculated and veri- Þ ed based on model testing and during sea-trials and the derived EEDI value is conÞ rmed to be over 20% below the applicable baseline for bulk carriers.(Copyright CNCo)MR #12 (42-49).indd 46MR #12 (42-49).indd 4612/9/2013 12:02:52 PM12/9/2013 12:02:52 PM
