Measurement of gravity at the Viking Gas Terminal, Theddlethorpe St Helen, Lincolnshire

This report describes the results of three gravity measurements made by the British Geological Survey (BGS) for ConocoPhillips Ltd., Viking Gas Terminal, Theddlethorpe St. Helen, Mablethorpe, Lincolnshire. The site of the measurement was on the floor of the Metering Calibration Laboratory, adjacent to the deadweight testing machines. The measurement was made by means of a series of links between the site and a British Precise Gravity Network (BPGN93) base station at St Sebastian’s Church, Great Gonerby, using a Lacoste and Romberg type G gravity meter. The values of gravity ‘g’ established for the measurement points at the Viking Gas Terminal are shown below: 9.813 529 8 ± 0.000 000 3 ms-2
