IRON and STEEL
Hydro has received contracts from Tersan Shipyard for the supply of aluminium solutions. The company will deliver its products for the upper sections of ships under construction for Norwegian shipowner Havila Kystruten AS.
“We are very pleased that we were able to use our innovative design and aluminium shipbuilding knowledge to support what will be among the most environmentally friendly coastal cruise ships in service,” commented Chris Moyle, Sales Director Marine & Offshore in Hydro’s Extruded Solutions business.
The two Norwegian coastal cruise ships (Kystruten) ships ‘Havila Capella’, ‘Havila Castor’, will be identical: 124.1 meters long, 22 meters wide and able to carry 640 passengers. The ships, powered by LNG (liquefied natural gas) and batteries, will be delivered at the end of 2020.
The advantage of aluminium is the possibility to design extrusions with a very high strength-to-weight ratio compared to steel. By choosing aluminium extrusions from Hydro, it was possible to reduce the overall weight of the vessels to improve displacement and draught issues. When using aluminium instead of steel, the overall weight reduction of the selected area was about 50%, Hydro said.
“We are pleased to be working with Hydro for the supply of their innovative aluminium products. Their know-how brought additional value to the projects while reducing the weight. We trust we will have opportunities to establish a good long-term cooperation,” said Turgut Özden, Deputy Shipyard Director of Tersan in Yalova.
