Shipbuilders New Concept to Increase Freight Carrying Capacity on Container Vessels Approved

Korean Group Gets the Go Ahead to Build Vessels Designed to Load More TEU

SOUTH KOREA – NORWAY – WORLDWIDE – Hyundai Heavy Industries (HHI) has received Approval in Principle for its innovative sliding bridge design for use on large container shipping vessels, by Norwegian classification society DNV GL, confirming that the concept complies with the DNV GL rules for the classification of ships. The revolutionary idea, named SkyBench, has been designed specifically to increase the freight loading capacity on box carriers is best understood by first viewing the short promotional video.

First demonstrated last year, the SkyBench concept is designed to increase the cargo capacity of large container vessels. The bridge and upper three decks of a ‘twin island’ design container would be constructed as a separate sliding block, mounted on rails and able to move over the length of two 40ft container bays. In combination with a resizing and relocation of fuel tanks and the utilisation of the void spaces beneath the accommodation block in a traditional design, this allows the addition of two extra 20ft container bays. The resulting cargo increase amounts to 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. Tor E. Svensen, CEO of DNV GL – Maritime, commented:

“This was an extremely interesting and exciting project and we are very pleased that HHI selected us to work with them to realise this concept. The SkyBench shows how the industry’s increased focus on efficiency and maximising transport capacity has really sparked innovation in design and operation. 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.”

The SkyBench mechanism takes ten minutes to operate, using four electric drive train units to move the block backwards from its normal position. The two 40ft side casings on which the accommodation block rests provide structural strength and hold lifeboats, provision cranes and utility rooms. One revolutionary feature is that, in an emergency, the sliding block is detachable and is designed to float independently of the vessel. HHI’s Senior Executive Vice President & COO of Shipbuilding Division, Yoon Moon-yoon, said:

“We would like to extend our sincere appreciation to DNV GL for the approval of our SkyBench concept design. As we have been doing over the past four decades, we will continue to provide competitive ships differentiated from others in terms of quality, reliability and technological capabilities to our valued clients. I believe that SkyBench, like many other previous technological breakthroughs we have shown to the world, will surely bring benefits to our customers.”

Those who follow the design of the latest mega carriers will appreciate the potential technical specifications of a new generation SkyBench container carrier:

Length over all: Approx. 400 metres

Length between perpendiculars: 383 metres

Breadth moulded: 58.6 metres

Depth moulded to main deck: 30.5 metres

Draught scantling: 16 metres

Potential container capacity: 19,400 TEU
