Fixed securing device limitations

Maximum securing load (MSL) is a term used to define the allowable load capacity for a device used to secure cargo to a ship.

The MSL of a securing device is to be checked before applied in a lashing arrangement. Fixed lashing fittings should have a defined MSL and be certified.

However, OPERATORS can allow alternative lashing fittings to be used if proof of strength can be shown in an acceptable manner.

The load capacity of an applied securing device is limited to the MSL of the device and the fittings to which it is connected, whichever is the least.

Since the diameter of some lashing holes are not designed for OPERATORS chains, the use of the smaller (climber) hook on an extension lever is allowed for use as end securing. It is however important that only the three-chain links between the climber hook and the tension lever are used (see below).
