DNV GL Approves HHI's SkyBench Concept to Increase Boxship Capacity

DNV GL Tuesday announced that it has awarded an Approval in Principle (AIP) to Heavy Industries Co., LTD. (HHI) for its SkyBench box ship design concept that increases cargo capacity for large vessels.

The design offers cargo capacity increases of 270 TEU on a 17-row wide 10,000 TEU ship, 450 TEU on a 23-row wide 19,000 TEU ship, and 350 TEU on a 20-row wide 14,000 TEU vessel.

Operators increasingly look to vessels with improved carrying capacity as, providing the vessel operates full, it reduces per TEU bunker costs, emissions, and other operating expenditure.

"The SkyBench shows how the industry's increased focus on efficiency and maximizing transport capacity has really sparked innovation in design and operation," said Tor E. Svensen, CEO of DNV GL Maritime division.

"Additionally, the potential of this design to offset reduced cargo capacity when choosing LNG as ship fuel means that HHI can offer a design tailored to meet stricter sulphur emission limits in the future," he added.

The design constructs the bridge and upper three decks as a separate sliding block mounted on rails, which can move over the length of two 40 ft container bays.

The optimal placement of fuel tanks and utilization of space beneath the accommodation block combined allows for the addition of two 20 ft container bays.

Yoon Moon-kyoon, Senior Executive Vice President & COO of Shipbuilding Division at HHI, commented: "I believe that SkyBench, like many other previous technological breakthroughs we have shown to the world, will surely bring benefits to our customers."

HHI said last month that its new Hi-FIN propellor device can reduce bunker consumption by up to 2.5 percent compared with the same type of vessels without the attachment.
