Container Weight FAQ
Q: Port container handling equipment generally has on-board weighing technology (‘PLCs’) typically accurate to within 5% and designed to prevent overloading of the equipment. If such data are integrated into other relevant systems (including those used for ship stowage planning) is this likely to be acceptable for determining verified gross mass under Method 1?
A: As an International issue, SOLAS only requires that the weighing equipment used to obtain the verified gross mass meets the applicable accuracy standards and requirements of the State in which the equipment is being used.
As a National issue, although accuracy of weighing equipment is a matter for national regulation, it is unlikely that a weighing device with a known margin of error of 5% would meet applicable accuracy standards.
