Ship of the Future: Container Feeder

More Cargo, Less Fuel, Greater Flexibility are Design Hallmarks

Deltamarin debuted a design that it dubs the first state-of-the-art container vessel of its series, the A.Delta2300.

With extensive R&D the maritime design house delivers what it believes to be a 'best-in-class' design that maximizes cargo capacity, flexibility and fuel economy.

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. Deltamarin and AVIC Weihai Shipyard are both members of the AVIC Group, which is ranked among the Fortune Global 500 corporations. “The overall efficiency and flexibility of this container vessel design provides the owners and operators with a solution for future transportation needs,” saidVesa Hamarila, Sales Director of Deltamarin Ltd.

The A.Delta2300 provides a container capacity of 2,322 TEU in five cargo holds and on deck. The increased cargo hold breadth improves stability in the fully laden condition. 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. Furthermore, intake can be optimised to a specific cargo profile and even further improved by considering route-specific loading.

The high flexibility of 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. Additionally, a high number of reefer plugs allows smart stowage and the reduction of unnecessary container movements. These features provide efficient and fluent stowage, which reduces time and costs.

Extensive effort has been focused on the A.Delta2300 hull form development to ensure low resistance combined with high propulsion efficiency. This included dozens of CFD calculations and three series of model tests at the Hamburg Ship Model Basin (HSVA). As a result, the vessel requires only low power at the design speed compared to present reference designs.

The daily main engine fuel oil consumption is decreased to 42 t/day at a 19-knot service speed resulting in superior fuel efficiency of 0.033 t/TEU/day.  A strikingly 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.
