Vessel and boom construction

Abstract

The invention relates to a vessel provided with a boom construction, especially a gangway construction, for transferring persons and/or cargo from said vessel to an offshore object or vice versa. The boom construction comprises an elongated mast structure extending in a direction substantially upwards from a deck of said vessel. Said mast structure is pivotally mounted with respect to a hull of the vessel in a manner such as to be pivotable with respect to said hull about a single pivot axis only. The boom construction further comprises a boom, especially a gangway, which is connected to the mast structure and which extends from the mast structure in a substantially sideward direction. Furthermore, the boom construction comprises at least one actuator for pivoting the mast structure such as to compensate for at least a part of a roll movement of the hull of the vessel.
