The following principles should be applied when securing in the longitudinal direction:
- Spring lashings are to be used to secure the plates in the longitudinal direction.
- The spring lashings are applied in pairs, with the two lashings crossing each other.
- In case it is not possible to apply the spring lashings so that they are in direct contact with all layers, the primary focus should be to secure the top layers. In any case, cargo representing at least 50% of the total weight should be in direct contact by a spring lashing in each longitudinal direction.
- The number of spring lashings in each direction is to be determined based on the dimensioning tables below.
Chain lashing - MSL 7.5 Ton
| Friction factor |
Secured cargo weight for each pair of spring lashings (MSL 7.5 ton) |
| μ = 0.3 |
102 ton |
Web lashing - MSL 5.0 Ton
| Friction factor |
Secured cargo weight for each pair of spring lashings (MSL 5.0 ton) |
| μ = 0.3 |
68 ton |
Web lashing - MSL 2.5 Ton
| Friction factor |
Secured cargo weight for each pair of spring lashings (MSL 2.5 ton) |
| μ = 0.3 |
34 ton |
