Shape factors for five different configurations of a triangular jack-up leg have been determined through load measurements on scale models in a wind tunnel.

The drag, lift, and yaw-moment shape factors of the different configurations were determined in the search for an optimal arrangementof the three raw water pipes that minimize the current load on the combined jack-up leg-raw water pipe-structure.
