Berth rates or liner rates. These expressions relate the freight rates applying to shipments by regular lines engaged in the trade in question. These freight rates become "standard" for a particular liner route and particular cargo.
Breakdown clause. Time charterparties contain a clause providing that if the ship is unavailable for the charterer's use because there is loss of time as a result of "...breakdown or damages to hull, machinery or equipment..." (among other causes) payment of the hire money to the shipowner ceases for all or some of the time lost.
Below bridges (BB). This term can be Found in instructions from port and charterers' agents to the ship to ensure that the ship is kept at the appropriate draft in order to ensure that it will have sufficient clearance above its highest point to pass safely below bridges (or overhead obstructions such as power cables) across a canal, channel or river in the approaches to a berth or port. To ensure the ship's clearance below bridges would be the shipowner's obligation.
Black list. Because oil tankers frequently load oil from Islamic countries these countries may place certain ports on a "black list" such as Israeli or South African ports, and if tankers are known to have called at ports in those countries, the tankers' names are on this black list and the ship can be boycotted and refused entry or cargo.
