New guidelines for box lashing raises stack weight safely amidships

Bureau Veritas (BV) has issued new guidelines to provide more flexible box lashing and deck-cargo placement on big ships, claiming its software can increase stack weights by 22 tonnes amidships and reduce handling, according to Shipping Gazette.
It joins other major classification societies that issued new guidelines last year, giving vessel operators the flexibility to sail on specific routes with heavier on-deck containers and less strict lashing arrangements.
Provided they use a class-approved lashing computer and the follow the required notation from their class society.
"It was developed by BV because operators want more flexibility with total stack weights so they don't have to keep moving boxes around in the stow to keep within lashing limits on each leg," said a BV spokesman.
"This all helped it validate modelling to show there was room to allow heavier stacks, which means quite often the operator does not need to move a box while in port to another stack, or they can save time with reduced lashing."
