This can lead to compensation problems: while the shipowner assumes responsibility for the ship in a charter of voyage, the shipowner may have to be compensated, in the context of a temporal charter, for losses or debts directly attributable to the charterer. An ice clause is inserted into a bill of lading or part of the charter when a ship is connected to one or more ports that may be closed to ice navigation upon the arrival of the ship or after the arrival of the ship. A lend-berth clause is inserted in a part to the charter, i.e. a provision according to which mooring times begin to count once the ship has arrived at the port of loading or unloading “whether it is docked or not”. It protects the interests of shipowners against delays due to the fact that ships have to wait for a berth. .
