Ishikawajima-Harima Delivers 50th Freedom Ship 'Acritas' Approximate measurements of the Acritas are: 440 feet in length, 65 feet in breadth, 40 feet in depth, and a draft of 30 feet. Her main engine is a 5,130-bhp IHI- S.E.M.T. Pielstick diesel engine and provides a service speed of ] 3.6 knots. The Acritas, a 14,800-dwt Freedom vessel, was delivered February 3 to the Pegasus Ocean Service group, Greece, by the Tokyo Shipyard of IHI (Ishikawajima-Harima Heavy Industries Co., Ltd.), Japan. The new ship is the 50th of 81 Freedom vessels so far ordered from IHI by shipowners in many countries, including the United States, the U.K., Greece, Hong Kong, the Republic of China, Italy, Switzerland and Kuwait. The Freedom vessels, jointly designed by IHI and G.T.R. Campbell, a Canadian ship- building consultant, are multipurpose cargo ships built to carry various cargo such as ore, coal, grain, containers, automobiles, lumber and steel materials. The first Freedom ship, the Khian Captain, was completed in 1967 and since then, Free- doms have been launched at the Tokyo Ship- yard at intervals of 23 days under a mass- production system. With the increasing de- mand for Freedoms, IHI's Nagoya Shipyard also began construction of this type of ship. Of 50 vessels, 45 ships have been delivered by the Tokyo Shipyard and five by the Nagoya Shipyard. On the other hand, Astilleros de Cadiz S.A. in Spain has completed six Freedoms since 1967, when it concluded a technical agreement for building Freedoms with IHI. Jurong Ship- builders Private Ltd., a joint venture between IHI, the Singapore Government and Jurong Shipyard, will also commence construction of Freedoms in July this year.
