An organisation with appropriate expertise in security matters and with appropriate knowledge of ship and port operations authorized to carry out an assessment, or a verification, or an approval or a certification activity, required by SOLAS chapter XI-2 or by part A of the ISPS Code. RSOs can be approved by flag State Administrations to: (1) carry out ship security assessments; (2) prepare ship security plans; (3) review and approve ship security plans, or amendment to Plans; and (4) carry out initial and subsequent verifications of ships. RSOs approved by some flag States include classification societies and private security firms.
Where a port State authority requires that specific ballast water procedures and/or treatment option(s) be undertaken, and due to weather, sea conditions or operational impracticability such action cannot be taken, the master should report this fact to the port State authority as soon as possible and, where appropriate, prior to entering seas under its jurisdiction. (BWM Guidelines, 8.1.1)
Whereas a possessory lien depends on possession of property, a maritime lien does not depend on possession and is not extinguished by transfer of title in the property to a bona fide purchaser who is not notified of the lien's existence. A maritime lien can therefore "travel with the ship" to which it attaches, and is not lost through a change of ownership.
The master of a UK ship must ensure that, when the ship enters a VTS area in the territorial waters of an EEA State (i. e. an EU Member State, Norway or Iceland), the ship must comply with the rules of the VTS if they are in accordance with IMO Guidelines. The master of a non-UK ship must ensure that, when the ship enters a VTS area in UK territorial waters, the ship must comply with the published or promulgated VTS rules.
Costs associated with the ship's employment, including costs of bunker fuel, canal tolls, light dues, port charges (including pilotage, towage, berth charges, agency fees, linesmen's charges, etc.), passenger-handling costs, and cargo- handling costs. Voyage costs are the costs incurred to earn the freight or other voyage revenue. They vary with the length of the voyage and the number of port calls.
On behalf of the owners of the ship and the owners of all "maritime property" on board including any cargo, cargo containers, bunkers, stores and other equipment, and the recipients of any freight at risk. On a ship with contractors' equipment on board, such as a diving support vessel, the owners of that equipment would also be included. All the owners of "maritime property" become liable for a contribution to the salvor's reward if he is successful.
