A Comparison of GPS and Satellite Altimetry for Height Monitoring on an Offshore Production Platform

Moira Tighe and John Macgregor

Abstract:	In 1993, Shell U.K. Exploration and Production, operator in the U.K. sector of the North Sea for Shell and Esso, carried out a precise GPS campaign for the purpose of providing offshore height benchmarks on several North Sea production platforms. The intention was to reference the platforms to stable land points in order that reliable monitoring of platform height could be carried out in the future. In 1994. a feasibility study for using Satellite Altimetry in conjunction with a Transponder was carried out on one of the platforms. This paper describes the Transponder trial and provides a comparison between the heights derived from GPS and altimetry.
