From Marine Link:

A new regulation requiring the gross mass of a container to be verified before it is loaded onto a ship enters into force today (1 July 2016). It will assist in ensuring that the millions of containers carried on ships each year are optimally stowed, thereby helping to prevent container stacks collapsing and containers being lost overboard, and the associated injury and loss of life.

According to the amendments to SOLAS regulation VI/2, now in force, either of two methods can be used to verify the gross mass of packed containers:

  • Method 1. Weighing the packed container using calibrated and certified equipment; or
  • Method 2: Weighing all packages and cargo items, including the mass of pallets, dunnage and other securing material to be packed in the container and adding the tare mass of the container to the sum of the single masses, using a certified method approved by the competent authority of the State in which packing of the container was completed.
