The Hamburg Ship Model Basin

Setting the Standard in Ship Optimisation

Arctic operations like exploration and exploitation of natural resources as well as shipping, in ice infested waters involves special challenges on humans and equipment different from those one will meet in moderate climates. HSVA’s Arctic Technology Department’s expertise includes among others the following topics concerning safety regarding operations in cold:

Ice load determination for arctic vessels and offshore structures

Ice load determination is one of HSVA’s main expertises. We offer model tests to determine ice loads for all kinds of vessels and offshore structures exposed to any kind of sea ice features.

In addition we offer lines review and speed-power predictions as well as theoretical ice load estimation. Please contact our department for individual requests.

Ice induced vibrations of offshore structures

Ice induced vibrations is a topic having a long history at HSVA. Full scale investigations have been made in the 1980s at a light house in the northern part of the Baltic Sea, Norstrømsgrund, where ice induced vibrations did occur. Ever since several model scale research projects have been performed at HSVA enlightening the subject of ice induced vibrations one of the latest is BRICE.

For details of test set-ups to investigate ice induced vibrations please visit Tests in the Ice Tank.

Ice management

Ice management is a topic that has been gaining more and more interest over the last years. In order to lower the ice loads on an operating vessel additional ice breakers assist the main vessel to resist severe ice conditions by breaking level ice, larger ice floes and first year ridges into smaller ice floes, the so called managed ice.

HSVA offers services regarding ice management by means of model testing as well as theoretical investigations. For information on ice management in model tests please view our ice features.

Icing problems

Icing is a phenomenon that occurs when fog or sea spray water meets cold air. The entire top site of a vessel may be covered by an ice layer. Besides the risk of dysfunctions of relevant onboard systems, the additional ice mass on the superstructures can have a negative effect on the overall stability of the ship.

HSVA offers services to investigate the degree of icing on certain top sites of the vessels. As scaling of icing problems is not state of the art the only theoretical investigations or physical testing in the full scale regime on individual parts can be performed. Such tests can be conducted in the Arctic Environmental Basin. For details of test in the Arctic Environmental Test Basin please visit the Tests in the AETB.
