Naikai Shipbuilding Corporation has completed construction of the 32,OOODWT general cargoship, Ivs Nightjar (HN: 691), for Diamond Island Maritime S. A. at the Setoda Works. The ship Ivs Nightjar has length of 172.90 meters and beam of 29.40 meters. The draught is 14 meters and the draft while the vessel is fully loaded is 9 meters. The main engine of the general cargo ship is Hitachi B&W 6S46MC with power of 6,400kW and the cruising speed which the ship can reach is 14.2 knots.
The Ivs Nightjar is a unique dry cargo ship consisting of five holds protected with double hull construction of the shipsides and bottom. The double hull construction increases the hull strength and improves ship stability against external damage. This also eases maintenance in the cargo holds and prevents the outflow of cargoes even if the outer shell is damaged. The ship has a wide beam and shallow draft, which permit entering ports with shallow waters as well as navigating rivers, channels, and lakes. A special stern form was designed to maintain the course despite the wide beam hull, even under seagoing conditions or within a harbor.
The cargo holds can accommodate grain, coal, ore, and steel products. Moreover, timbers can be loaded inside cargo holds and on the exposed deck. The Nos. 2 through 4 cargo holds are of the box-shaped type. Cargoes can be handled with four 30t deck cranes. The wide hatches facilitate loading and unloading of lengthy products. The lon-gitudinal hull strength allows loading of heavy ca goes in every other hold. If Nos. 2 an 4 holds are empty, the Nos. 1,3, and holds can load cargoes to the full loa waterline. The Ivs Nightjar is an ECO-SHI employing a low fuel consumption pr< pulsion system based on a low-spee main diesel engine and large diarr eter propeller.
