At the present market rate, bunker cost is one of the largest operating expense incurred in a TC voyage. With such high costs involved, it becomes imperative for the charterers to know the exact bunker quantity onboard at the time of supplying bunkers.
To prevent bunker misappropriation AVA Marine's exclusive division "Bunker Detective" is able to offer 221B Surveys, commonly known as Bunker Detective Surveys, to ship operators globally.
What are 221B (or Bunker Detective) Surveys?
221B or bunker detective surveys are carried out by marine surveyors on behalf of the charterers to find concealed (hidden) bunker fuel onboard.
To find concealed fuel someone qualified has to go on board the vessel and get their hands dirty. In order to prevent fuel losses "Bunker Detective" experienced surveyors offer impartial, independent quantity measurement inspection services for marine fuels, issuing detailed bunker survey reports to confirm fuel delivery and report any bunker fuel shortages.
Why are they called 221B Surveys?
The term is derived from an historic reference to the fictional detective Sherlock Holmes' London residence where he ran his consulting detective business - 221B Baker Street.
How Bunker Fuel is Concealed?
There are many ways to conceal fuel on a vessel - some of the examples are:
Short bunker delivery
Use of 'magic pipes'
Altered sounding pipe lengths
Non-class approved and / or altered sounding tables
Sounding tapes not properly calibrated
Doctored fuel gauges and so on….
What is a "Magic Pipe"?
Magic pipe is a terminology used when finding conceal bunkers. If used properly - to an untrained eye - it can be hard to detect and thus making bunker fuel disappear just like "magic."
These magic pipes are fabricated onboard by marine engineers and designed to fit tightly inside the actual sounding pipe. The bottom end of the magic pipe is closed and the pipe pushed through the fuel to the bottom of the tank. During sounding, the tank thus appears empty or gives false soundings.
Note "magic pipe" is also the term used to bypass the OWS (Oily Water Separator) connection in order to dump oil overboard. Unlike the use of magic pipe for bunker concealment, use of magic pipes to bypass the OWS is a criminal offence and heavy fines and penalties may be imposed and / or imprisonment.
Cost / Losses for the Charterer
For example concealing just 10 metric tonnes (mt) of MDO @ $900/mt is $9000 and 20 mt of IFO @ $650/mt. comes to $13000. That's $22,000 in losses for the charterer. This is a very small find. Normally a typical find would be in excess of 30 mt and on a good day we have found in excess of 70 mt with findings as large as 120 mt.
That's over $75,000 in losses.
