The UK Maritime and Coastguard Agency has dropped the tolerances it was considering for weighing equipment used to weigh a container for the new SOLAS VGM requirement.
One of the issues that has been holding some terminals back from investing in equipment to weigh containers is the lack of any clarity over the accuracy standards that equipment must meet. SOLAS says only that equipment must “meet the applicable accuracy standards and requirements of the State in which the equipment is being used”.
The UK Maritime and Coastguard Agency (MCA) had been consulting on a proposal for two weighing tolerances for equipment used to generate a Verified Gross Mass (VGM) using method 1 (weighing the container):
- +/- 400kg up to 20T then +/- 2%
- +/- 300kg up to 15T then +/- 2%
Sources involved in the process say some port operators and weighing equipment suppliers had expressed concerns these tolerances were unreasonable. MCA has this week issued new guidance on the VGM requirement, including a procedure for applying for approval to use Method 2 (weighing cargo items and calculating the total weight of a container).
The MCA has dropped any requirement for a specific accuracy level, opting instead to set an enforcement level. It stated: “The verified gross mass should be as accurate as reasonably practical taking into account methodology and operational variances. The MCA has set an enforcement tolerance of ±5% or ±500kg, whichever is the greater value to avoid disruption within the supply chain, however this value is for enforcer’s guidance only and it is the shipper’s responsibility to be as accurate as possible”.
Method 1 equipment includes “weighbridges, or lifting equipment fitted with load cells, or other approved weighing equipment to determine a loaded container’s Verified Gross Mass (VGM)”. Unlike other jurisdictions the MCA has not stated that it requires two 20ft containers on a trailer to be weighed separately, or said anything about how the weight of the truck and trailer is to be obtained. It stated only that “Calculations may be used as part of the method 1 process”, so these items do not in fact need to be weighed as part of the VGM process.
With regard to certification and enforcement, the MCA states: “ Method 1 users are required, on request by the MCA or other body, to provide both of the following:
- Evidence that the weighing equipment has been supplied/maintained for the purpose of determining the VGM of a loaded container and is capable of producing a ticket (electronic record). Each ticket must include the container number, the VGM of the container, and the procedures for, and records of, any calculations which have been made. If this information is produced as an electronic record, it is essential that it is able to be produced without delay as a paper document.
- Records kept of maintenance and verification (calibration) procedures, including any corrective / remedial actions taken.
