As with weighing any large item, a successful weighing in the offshore oil industry requires decisions regarding many aspects of the process:

o Detailed planning and coordination
o Selecting an appropriate weighing system and measuring devices (load-cells) o Approving of a weighing procedure
o Issuing a report documenting the results of the weighing
o Documenting deviations from an approved procedure

Defining the number of load-cells to be used requires an understanding of the capacity and uncertainty imitations of the devices, as well as the structural design of the Module. There is no formula available that determines the number of load-cells to employ for a weighing.
Factors to be considered for a multiple load-cell weighing are presented in this paper. A combination of good working knowledge of the various elements and application of sound engineering judgement will be necessary to make the many decisions that will arise during the planning and execution of a weighing.

This paper presents the factors to be reviewed and the mathematics to be used to determine the overall uncertainty of a weighing system. A basic checklist is also provided to assist the user when attending a weighing. Information in this paper is applicable for performing any weighing using a multiple load-cell system.
