..., a protection frame will be placed over to protect the tree after it is installed and in operation. The frame is to be installed over the tree to sit on a seabed of very soft clay and reused after serving its initial purpose for other areas with similar tree and water depth conditions. The soft soil condition...

... risks for suction bucket foundations. This paper presents recent installation experience of two suction bucket jackets in Southern China with an aim to provide guidance to future installations in similar soil conditions. INTRODUCTION The offshore wind industry is fast-growing in China due...

... Abstract As offshore wind farms are moving further offshore and into areas with more complicated ground conditions, alternative offshore foundation concepts are becoming increasingly relevant. Drilled foundations are employed in regions with stiff soil conditions where traditional installation...

..., China ABSTRACT SPM System The subsea PLEM were connected with two flexible risers of Chinese Subsea Pipeline Lantern configuration in CALM Buoy System. A hybrid pile foundation were applied as the super soft clay soil condition. This paper Fig. 1: The SPM CALM Buoy System General Layout presents...

... topography, soil conditions, and modelling errors. The consideration of variability allows for the use of a strain demand with a specified probability of exceedance in a deterministic strain-based design. The availability of a probabilistic characterization of strain demand also allows the application...

... with length to diameter ratios of 2, 4, 6 and 8 are reported. The influence of the soil condition, length (or L/D), loading angle on capacity of piles and suction anchors are analyzed respectively. The shape of the failure envelopes of these two kinds of anchors is compared to analyze the capacity...

... installation under its own weight as well as suction in Caspian Sea bed. An elaborate geotechnical study at around 700 to 1100 m water depth zones was conducted lately to obtain the seabed soil conditions. The angle of friction between pile and surrounding soil and soil strength parameters were determined...
