Duct Keel

The name given to a tunnel structure which tends to run from the fore end of the engine room to the collision bulkhead. It is usually large enough to accommodate an upright walking man. Access is normally gained through a manhole cover situated at the bottom of the engine room near the fore and aft line and close to the forward engine room bulkhead. Its function is to carry pipelines through the forward length of the vessel. There is no need for an aft ‘duct keel’ because the same function is available with the shaft tunnel arrangement. … [Read more...]

Damages for Detention

If the charterer delays (or "detains") the ship by loading or discharging in a longer time than agreed or for any other reason, he has breached the contract and must compensate the shipowner. Normally, if the Charterer exceeds the laytime allowed in the charter, he pays compensation at an agreed rate of demurrage. However, if demurrage is not agreed at the time of entering into the contract, or if the agreed excess time more than the agreed laytime is exceeded, damages for detention is the name given to the compensation. … [Read more...]

Dreadage or Dreading Clause

Grain is usually carried in. bulk or in bags. In a charterparty for grain cargo, a clause can give the charterer the option to ship general cargo with certain restrictions, such as a minimum quantity, and exclusion of cargoes that may cause damage to any grain loaded.

If this option is exercised freight must be paid on the ship's deadweight cargo capacity for wheat in bags at the rate agreed upon for … [Read more...]

DOP (Dropping Outward Pilot)

This expression is used to identify the point at which a time-chartered ship is "delivered" to the Charterer or "redelivered" to the shipowner. The place of delivery and redelivery are the places where the time charter commences or comes to an end. Normally the place of actual delivery or redelivery and where an "on-hire survey" or "off-hire survey" would be carried out would be a berth, but the time from which hire is to be paid or until which hire is paid may be an "artificial" point such as when the ship has left the berth, and the pilot who assists with the navigation of the ship to the … [Read more...]
