Specifically, according to the Club common failings found include:
- The angle of lashings between the vessel and the cargo to prevent either tilting or sliding, being outside of the effective range.
- No lashings between the cargo and the trailer.
- No lashings between the cargo and the vessel to prevent tilting.
- Deficient lashing strength due to insufficient number of lashings or inadequate SWL of the lashing materials or excessively worn lashings.
- Loose stow of cargo on the roll-trailer.
- No account taken of the centre of gravity of the loaded roll-trailer which can often be high above deck level.
- The use of “silly-loop” lashings (loop lashings with their ends fastened to either side of the trailer) – these do not provide any direct securing effect.
- The use of “Friction Loop” lashings, being lashings passed from one side of the trailer to the other, over the cargo. Although such lashings can provide some enhanced friction between the cargo and the trailer, the cargo can move about under the lashings.
In the meantime, the Club shows (below) the correct lashings method – note cargo is secured to the roll-trailer (blue lines) and the roll-trailer is secured to the deck (red lines) to prevent sliding. Additionally, green lashings are used to prevent tipping of the cargo unit.
