STF stands for pretensioning force, LC stands for lashing force. It is important to distinguish which securing method is used. In the case of non-positive securing methods, it is the pre-tensioning force (STF) and also the existing friction coefficients between the load and the loading surface that are important. In the case of positive-locking variants, on the other hand, the lashing force (LC) is the decisive factor.

We will tell you more subtleties in our load securing technical article: "Episode 28: Pretensioning force STF and lashing force LC".
Both abbreviations are described in the 2015 CTU Code. MSL stands for "Maximum Securing Load" or operational strength and LC for "Lashing Capacity" or lashing force.

The MSL corresponds to the LC. The abbreviation MSL is mostly used in maritime transport, the abbreviation LC is rather used in land transport.

The abbreviations stand for load values on securing equipment which must not be exceeded when used in load securing. The breaking load, i.e. the load at which the load securing equipment fails, is the basis for both specifications. The CTU Code defines precisely when the MSL/LC is reached in proportion to the breaking load. A safety factor of approx. 33-75% (depending on the lashing equipment) is included.

A more detailed list and exact values can be found in our technical article: "Episode 26: MSL and LC - Abbreviations with meaning".
An overloaded container is a problem. If many containers with too wrong weight are on a ship, it can quickly end in a disaster. Therefore, the actual weight of a container, consisting of cargo + packaging + securing means + tare weight, must be determined. In this regard, the World Shipping Council determined, "The responsibility for recording and documenting the verified gross weight of a packed container rests with the shipper."
This clearly regulates liability. So what needs to be considered in detail? Our technical article provides you with all the information you need: "Episode 18: Verified Gross Weight - Container"
