On August 10, 2012, the Atlantic Container Line (ACL) announced their contract with the Hudong-Zhonghua Shipbuilding (group) Co. Ltd. China for the construction of five new RoRo/Container (ConRo) vessels. The vessels will be the world’s largest and most innovative ConRo vessels ever built. The five ship order will form the G4 (Generation 4) class and on delivery, they will replace ACL’s current fleet of G3 vessels that were built between 1984-85.
Responsible for the Basic Design of the new G4 ConRo vessels, KNUD E. HANSEN A/S will deliver to the shipbuilder a full Basic Design package, including: class drawings, general design of hull and outfitting, machinery plant arrangement, HVAC and electrical and automation design.
Over the past year, KNUD E. HANSEN A/S has worked closely with the Hudong-Zhonghua shipyard, as well as in close consultation with the shipowner, to develop and optimize the design to the Client’s needs.
The vessel has been designed and will be constructed as a modern partly open top ConRo vessel carrying both containers and RoRo cargo. RoRo spaces are arranged amidships and container bays are arranged in both ends of the vessel. The vessels will have adjustable RoRo decks plus many other innovations, and have far better energy efficiency than their predecessors.
The vessel will have a transom stern, high efficiency rudder and single screw fixed pitch propeller directly driven by a slow speed diesel engine. The engine room will be located aft and all living quarters, including the navigation bridge, will be located amidships, on top of garage.
The vessel is intended to trade on international voyages and has been designed for transatlantic operation. The ship shall have good seagoing capability and reliability, good manoeuvrability at sea and in port and has been designed and optimized for efficient cargo turnaround in port.
