What is Loss Control?

Loss Control also called cargo assurance is the policy designed to manage the risk and exposure to commercial loss associated with the trading, transport, handling and storage of Oil and petroleum products. The operational risk and exposure is mitigated by use of expert personnel to oversee all aspects of the custody transfer process.

Basic Loss type chart

Did you know?

Any of these small factors can lose you 50 metric tons

  • 1 degree difference in temperature
  • 1 degree list
  • 1 metre trim
  • 1 metre swell

You can lose 1 metric ton from....

  • 1cm  ullage in each vessel cargo tank
  • 1mm ullage in large shore tanks

Vessels usually have a minimum of 10 cargo tanks so this equates to a potential loss of 10 metric tons or more. During heavy swell cargo tank ullages can be +/- 50cm or 50 MT

Slack shore lines

A shore line can contain as little as 50m3 or as much as 5,000 m3. If they are just a little bit slack (empty) you can lose considerable amounts of cargo.

Storage and cargo tanks can change shape

This is called 'Tank Deflection' and makes quantification prone to inaccuracy and is very common

Cargo is lighter at the top

Samples taken from the top of any tank will be lighter and have less heavy contaminents

Water

Free water is heavy and often accumulates in cargo and shore lines. It can then be discharged through the line system into your ship/shore tank.

Water can hide

It can be in suspension then fall out as free water in your shoretank or ships tank.

How to spot a density issue

Look at the percentage difference between volume and weight – it should be the same within +/-0.01%

How to spot a BS&W issue

A higher BS&W at disport lowers your net figures and gives a larger percentage difference. So check the percentage losses net v ​gross
