Container Ship with Cargo

Adjustments to SOLAS rules in July mean shippers must accurately state the weight of all containers transported over the seas prior to shipping

New rules regarding cargo weight certification are easy to follow with Inscale’s wide selection of weighing balances and accessories.

Implemented in July, the Safety of Life at Sea (SOLAS) amendment requires that shippers and carriers must declare and document accurate weights of all shipping containers before they are loaded on ships. The International Maritime Organization (IMO) oversees the SOLAS convention, and decided to make changes following some serious accidents involving overloaded or improperly packed cargo transport vessels.

History of SOLAS

Following the April 1912 sinking of the Titanic, the first version of SOLAS was passed in 1914. The passenger ship was seriously damaged after colliding with an iceberg in the freezing water, and sank within three hours, killing more than 1,500. That version provided requirements for emergency equipment, safety drills, continuous radio watches, and specified the number of lifeboats necessary based on passenger counts. An International Ice Patrol was established to monitor icebergs in the North Atlantic shipping lanes. Due to the start of World War I, the 1914 version never took effect, but a later version was adopted in 1929.

New changes to SOLAS

The revisions adopted in July 2016 mandate that the VGM (verified gross mass) now is required for containers and goods before they can be loaded onto ships. There are two ways to meet the weighing requirements, and both must be performed using scales that are calibrated and certified to the national standards of the country where the weighing takes place.

Method 1 requires that shippers weigh the entire loaded container.

Method 2 requires that shippers separately weigh everything placed inside the container, including cartons, crates, pallets, and materials used to pack and secure the contents. The weights are totaled and added to the weight of the empty container to arrive at the VGM.

According to SOLAS, scales and balances must meet certification and calibration standards issued by the country in which the scale is operated. In the United States, the National Type Evaluation Program (NTEP) oversees the approval process of weighing instruments. In Europe and other countries, compliance is regulated by groups such as Measurement Canada, International Organization of Legal Metrology (OIML), National Regulator for Compulsory Specifications (NRCS), and European Commission (EC).

To help shippers and carriers comply with SOLAS rules, Inscale offers a selection of weighing scales and balance equipment, including pallet beam scales, crane scales, platform scales and floor scales.
