The 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 bottom tanks, one U-type tank and two water ballast heeling 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, Cyclohexane, etc., as well as refined petroleum products (products with flash 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 flap and a fixed 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 afloat 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 coating 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 manifold platform area and to forecastle deck on the upper deck.
