Finland-based ship designer Deltamarin has shown the first renderings of the newly designed A.Delta2300 series container ships.
The A.Delta2300 provides a container capacity of 2,322 TEU in five cargo holds and on deck, with the increased cargo hold breadth improving stability in the fully laden condition, according to Deltamarin.
Together with the ballast-free approach, this results in an increased utilisation rate of about 73% (1,700 TEU) of nominal container intake in the homogeneous loading condition at scantling draught carrying a 14t TEU container, the Finnish designer says.
The A.Delta2300 allows pallet-wide container stowage as well as three tiers of high cube containers in the cargo hold without losing container slots, Deltamarin says, with a high number of reefer plugs allowing smart stowage and the reduction of unnecessary container movements.
Extensive effort has been focused on the A.Delta2300 hull form development to ensure low resistance combined with high propulsion efficiency, the designer says. This included dozens of CFD calculations and three series of model tests at the Hamburg Ship Model Basin (HSVA).
The daily main engine fuel oil consumption is decreased to 42 t/day at a 19-knot service speed resulting in fuel efficiency of 0.033 t/TEU/day. A low deadweight per TEU ratio of less than 16 DWT/14t TEU is thus achieved, which is commonly gained only in larger container ships. This efficiency decreases the EEDI (Energy Efficiency Design Index) value to approximately 37% below the IMO reference line complying with Phase 3, which enters into force in 2025.
Optional features of the A.Delta2300 container feeder include LNG readiness, a flexible number of reefer plugs, shaft generator PTO/PTI, scrubber/SCR implementation and gearless design as well as several ice classes. Furthermore, stretched derivative designs are available, the A.Delta2500 and A.Delta2600.
The development work has been supported by AVIC Weihai Shipyard in terms of construction friendliness, and has been reviewed and commented on by DNV GL considering the application of the latest rules and industry practices.
