... geotechnical aspects of the effects of the gas emanation on the foundation soil properties for four boreholes. Around the site, geotechnical studies in 1978, 2008 and 2011 were conducted for foundation design of platforms. First, it was found that the water content and unit weight of the clay and sand...

...1. Introduction In recent years, more and more oil platforms with six or eight legs have been adopted in Bohai Gulf, China. The leg piles with diameters of 2m or more have to be driven about 100m below the seabed. Due to transportation and hoisting difficulties, these piles have to be manufactured...

... established. The key issue for any nearshore geotechnical site investigation is the choice of working platform from which to deploy sampling and testing systems. The choice of platform is a function of water depth. In water depths up to 20 or 25 metres conventional mobile jack-up rigs are usually deployed...
