Update: Container Weight Verification

There are now less than six months remaining before the implementation of the amended Safety of Life at Sea (SOLAS) rules requiring that any container to be loaded onto a vessel to which these regulations apply, must have its gross mass determined in advance through weighing – there are no exceptions. While the onus is upon the shipper to fulfil this obligation, the most practical location at which weighing can take place is at the ports and terminals, where lifting is a part of the existing cargo handling process.

The Options for Ports Offering VGM Compliance

There are numerous candidate systems and technologies that are capable of delivering the required accuracy of measurement required under the new SOLAS regulations. Not all, however, are particularly practical in terms of their ability to operate as a part of the existing flow of cargo between consignor and recipient. This paper reviews the options available to ports with some of the considerations that port operators may take into account when making choices about how to provide a VGM service
