To Offer Quality Investigative Inspections and Audits

Oil and Gas | Loading and Unloading Surveys


This inspection is conducted to the vessel at the beginning and/or end of the chartering and aims at checking the overall condition of the vessel.

The on/off hire condition survey is an inspection of vessel’s holds, main deck, cargo working areas and external shell plating. It is performed in order to identify any damage present prior to the vessel going on/off hire.

By doing it repetitively for many years, our surveyors became experts in analysing a vessel. The eyes of an experienced professional inspect every bulkhead, ladder, pipe, corrugate, lower and upper hoppers, bilge, tank top plating, manhole, hatch coaming, hatch covers and many other structures.

Observater Marine & Cargo Surveys start the attendances of on/off hire condition surveys at berthing time, before the commencement of loading operation, or, at the end of a discharging operation, in order to inspect cargo without cargo inside for clear and accurate inspections.

Our company details the findings of the inspection in the Survey Report that includes the anomalies found, general particulars of the vessel, relevant documents and a photography list showing the actual condition of the vessel. Observater Surveyors works to issue the Survey Report within three days after the completion of inspection.

This survey is compared with the previous condition survey carried out to the vessel, in order to determine if new damage have occurred to the vessel from cargo operations and/or stevedores damage.


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.
