Offshore Ship Designers (OSD) has unveiled a new series of Ice Class vessel designs, especially suited for marine services around the development of new arctic ports, terminals and offshore structures.
A prerequisite for this type of vessel, operating under arctic conditions, is the ability to deal with the presence of first-year or floating ice, cold conditions and less developed shore facilities. Apart from the ability of the vessels to perform their specific tasks, typical design requirements are increased strength, special installations for tank heating and winterization, high manoeuvrability and limited draft.
Development of this series of designs follows the extensive experience OSD has gained with the development of the shallow-draft anchor-handling tug supply vessels Arctic and Antarctic for Ark Shipping. Arctic and Antarctic were designed in close co-operation with the owner, have a Bureau Veritas 1A Ice Class Notation, and are fully equipped to operate in the challenging and extreme conditions of the Caspian Sea, where ice formation of around 80 cm during the winter period is not exceptional.
