International Rules for Cargo Securing Onboard

Regarding cargo securing at sea, the rules and regulations are divided into cargo securing to the vessel and cargo securing in cargo transport units. Safe transportation of cargoes requires both of these tasks to be properly performed. The efforts should be guided by applicable international rules and regulations, the structure of which is described in this section.

Cargo Securing Calculation Software

To check the cargo securing with advanced calculations can, from time to time, be both unpractical and time-consuming. A way to check cargo securing arrangements easier and faster is by the use of ship cargo securing software. The program should be able to, quickly and easily, make calculations that show the user how much cargo securing is needed for the cargo unit secured onboard the vessel.

MariLash is an example of a cargo securing program based on the specific vessels' data where the user has to insert the following data.

The programme will determine the centre of gravity of the cargo and then use the same calculation methods to determine the required cargo lashings for any condition of the vessel. This can also take into account loading beds, rubber matting, and other vessel measures in addition to the predicted weather and vessel motions.

Another consideration will be the location of the cargo within the vessel. This will have an effect on the accelerations experienced by the cargo with a factor of the distance off the centreline as well as the height above the keel.

Choose vessel and location onboard where the cargo unit will be stowed.

Attach lashings to secure the cargo unit on the roll trailer and lashings to secure the cargo unit and the roll trailer to the vessels deck.

Then MariLash programme will tell the user when the securing arrangement is sufficient by some green ”thumbs up” signs to show the cargo is well secured for the coming voyage.

Once you have got three green thumbs up (in the right lower corner on the screen), the cargo unit is secured for the intended sea journey.

The information can be printed out with a drawing showing how the lashings shall be arranged and also states in text how many lashings shall be used and the MSL of the lashings.

This is a quick and easy way where the user doesn´t have to make any calculations Instead, the program will make the calculations based on accelerations in the chosen position onboard, MSL of lashing equipment, angles of the lashings, and type of lashing method used (top-over, half loop, spring or direct lashing).
