|What we do

We are a marine and cargo inspection firm, our expertise includes draft surveys, pre-purchase condition surveys in Kenya, Bunker surveys, damage inspections and related services. In a normal ship bunker and condition survey we check, vessels safety to crew, cargo and environment.

Our Bunker survey ensures that there is transparency, fairness, and that inspections are carried out thoroughly and diligently with skill. All gauges are checked and inspected for any alterations and discrepancies.

We also carry out Hold Cleanliness inspections and Under Water Hull Inspections

In Mombasa on/off hire bunker & condition surveys are most often required to be performed combined and, we also either carry out just on/off hire bunker survey or on/off hire condition survey separately.

It is common to be performed jointly with the other interested parties, as second or even third parties, most common is one company appointed by Owners and other by Charterers.

Our surveyors carry out diligent and thorough checks and sounding of all bunkers tanks and perform corrections of soundings to vessel’s trim and list to find out the volume in tanks. Then corrections for temperatures and specific gravity are applied, 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.

Through experience our surveyors are able to detect and document accurate bunkers (ROB) and consumption. While avoiding any common and emerging industry tricks and malpractices
