The On/Off Hire Bunker Survey

---

 The on/off hire bunker & condition surveys are most frequently required to be performed combined but we also perform either just on/off hire bunker survey or on/off hire condition survey separately. It is also common to be performed jointly with the other interested part, being one company appointed by Owners and other by Charterers. 

The bunker survey is required in order to calculate the exact amount of bunkers on board at the time of vessel’s delivery/redelivery.

The vessel is delivered by the owner to the charterer, in case of On-Hire. At this time, usually, the Master issues a Delivery Certificates stating the place, time, parties involved and total amount of bunkers on board.

In case of redelivery, the vessel is redelivered by charterer to the owner by the end of the chartering (Off Hire), when it is issued the “Redelivery Certificate”.

The Surveyor carry out sounding of all bunkers tanks and performs corrections of soundings to vessel’s trim and heel to find out the volume in tanks. Than it is applied corrections for temperatures and specific gravity, in order to determine the actual quantity of bunkers on board at the time/place of survey. The Surveyor checks vessel’s consumption, as per perusal of engine log book and chartering details, to establish the amount of bunkers remaining on board at Delivery/Redelivery time.
