Aker Yards develops open top boxship design

Aker Yards, Merchant Vessels has introduced a new-design open top containership, the Aker CS 1500 OT. It is also available in CS 1300 OT and CS 1700 OT versions.

These new generation feeder ships adopt a no lashing, open top concept to cut cargo handling times in ports.

High cell guides support the container stacks and boxes are secured by utilization of automatic twist locks between the containers rather than conventional lashing.

A compact design philosophy results in a very efficient space utilization with a high container capacity and a significantly lower specific gross tonnage compared to other open top designs.

The forward deckhouse increases the container capacity considerably and creates superior visibility when navigating in the small harbors and dense traffic zones for which the ship has been designer.

Calculations and model tests show a very good seakeeping capability in relevant sea states.

Attention has been drawn to achieving a high flexibility for the carriage of reefer containers; a total of 296 FEU can be transported in open holds and in three tiers in on deck.

One cargo hold is designated to the carriage of 45 ft containers, other unconventional formats (e.g. EURO containers) can be accommodated on the aft deck above the engine room.

No substances harmful to seawater are carried next to the outer skin.

Special emphasis has been placed on achieving efficient usage of low sulfur fuels in designated coastal areas.

An optimized hull form with a wake equalization duct and a rudder bulb result in a remarkably economical fuel consumption.

The project design can be tailored to the individual demands of the customer.
