Design and Application of Force Dynamometers

Abstract

In model basin testing it is a common practice to measure both the global and local loads on offshore and mari.ne structures. The purpose of this paper is to describe the design and application of a variety of load cells for the measurement of these loads under a simulated wave environment. Several specific examples are chosen for both marine and offshore structures and the load cell design for these structures is discussed. In this regard, it should be noted that the distinction between the two types of structures is made to differentiate the in-place offshore structures from the floating ocean-going structures. The model structures chosen are jacket type structures and submarines. The load cells that are included have application in the measurement of both local and global loads on these structures. The calibration method and calibration results are given. Checks on the accuracy of measurements are often made which are illustrated. Anomalies present in any of these data are discussed. The load cells chosen for the discussion in this paper are considered to have a wide variety of applications.
