Cargo retention clause. When liquid cargoes are discharged from tankers differences can occur between the quantities stated in bills of lading to have been loaded and the quantities measured on discharge.
Convenient speed. The stipulation in a voyage charterparty that the vessel, after completion of loading, shall proceed with all possible speed to port of destination, is usually changed into "with all convenient speed" or "with all reasonable speed" The latter expression eliminates any controversy, which may arise about the speed actually maintained on the voyage.
Colliery guarantee. This is an undertaking in a contract between the colliery owners and the charterer or shipowner. The colliery agrees to supply the cargo and load the vessel on usual colliery terms. If a reference to "colliery guarantee" is incorporated in a coal charterparty the charterer is relieved from any liability for delay to the vessel if the colliery does not supply the coal within the agreed laytime.
Container slot management (CSM). The objective of this management in a liner operator’s corporate plane is to achieve the best utilisation factors of the container spaces or slots available on-board the carrier’s own vessels. The revenue is increased by the volume of the goods carried. If slot space cannot be found in the carrier’s vessels, the carrier may use “vessel sharing arrangements” (VSA) with other carriers under which slots on-board vessels are reserved for fellow carriers.
Containerisation system. Containers are not new. From earliest times human beings have used objects designed to hold other things. Even nature did this before man thought of it. The egg is an obvious example. The use of containers in shipping is also not new. Jars for oil and wine were used thousands of years ago.
