... rising gas in terms of sources, pathways, flow calculations, gas experiments trials, and calculations, settlement effects and precautions, as well as its effect on GBS, on bearing capacity (especially during storms) and on shallow and deep foundations. 1. Sources of Gases The most obvious sources...

... significance as relative density reduces. The proposed method in this paper is based on that given by Schmertmann (1978) for the settlement of shallow foundations on sand. 3.1 The Schmertmann method A CPT based method to predict settlement of shal- low foundations on sand was first published by Schmertmann...

... stresses generated by the platform weight. The GBS is equipped with a structural and environmental monitoring (SEM) system. This system allows continuous surveillance of important parameters describing platform behaviour, including settlement, water pressure in the skirt compartments, earth pressure...

... aspects of foundation defor- mation are discussed further in the following subsections. 2.3.1 Use of suction preloading Initial assessments of vertical and differential settlement in- dicated that, over the life of the platform, large movement might be expected under the various combinations of self...
