Approval in principle for HHI SkyBench
An innovative sliding bridge from Hyundai Heavy Industries (HHI) has received approval in principle (AiP) from classification society DNV GL.
The concept, intended to increase capacity on large container vessels, features a bridge and three upper decks mounted on rails and able to move over the length of two 40ft container bays. By using the void beneath the sliding block for additional storage, as well as resizing and repositioning fuel tanks, room is created for an additional two 20ft container bays.
The system increases cargo capacity by 270 teu on a 17-row 10,000 teu ship; 350 teu on a 20-row wide 14,000 teu vessel; and 450 teu on a 23-row 19,000 teu ship.
Yoon Moon-kyoon senior executive vice president & COO of shipbuilding division, HHI was presented with the AiP certification by Tor Svensen, CEO of DNV GL – Maritime at a ceremony held during Nor-Shipping.
Moon-kyoon said: “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.”
Svensen added: “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. The two 40ft side casings on which the accommodation block rests provide structural strength and hold lifeboats, provision cranes and utility rooms. In an emergency, the sliding block is detachable and is designed to float independently of the vessel.
