Abstract
In order to reduce the risk of an offshore vessel capsizing in the event of a collision resulting in damage to its columns, a strengthening member is arranged in front of at least one of the columns, between the work platform of the vessel and the supporting hull. The strengthening member comprises a watertight box structure rigidly connected to the platform, and a tubular, also displacing part, extending between the box structure and the hull. The box structure has considerable volume and is situated so high that it will not be damaged in the event of a collision.
