There are two main spots a ship can be delivered
1. DOP (at the last port where the ship comes open under previous employment)
2. APS (at the port of load)

Lets look at an example. A ship is discharging coal in Japan and will finish in 10 days time. Her owners are now negotiating her next employment which is another stem of coal loading from Indonesia (they will need to ballast there empty).
The parties are in a time charter negotiation and the charterer wants to take the ship APS Indonesia (doesnt want to pay for ballast leg) but the shipowner wants the charterer to take the ship DOP Japan (when she finishes discharging in Japan). So this discussion is about who pays for the ballast leg. That should give you an idea regarding the concepts.
Ok here is a question for all reader of the blog. Apart from DOP or APS delivery can you name other types of Time charter delivery (other than these two)? There are a few unusual ones out there.
Come on and join in - let me know your ideas (even if they are a guess)
