The vast ocean floor holds abundant mineral resources, characterised by a wide variety,
large reserves, and high grade. It has tremendous prospects for development and utilisation …

The retrieval of deep water subsea installations resting on soft soil, such as “mudmat”
shallow foundations, can be a difficult and costly operation if significant resistance to uplift is …

The footprints that remain on the seabed after offshore jack-up platforms completed
operations and moved out provide a significant risk for any future jack-up installation at that …

Realistic predictions of service life of steel catenary risers (SCR) require an accurate
characterization of seafloor stiffness in the zone where the riser contacts the seafloor, the …

针对自升式钻井平台现有冲桩系统存在的问题, 提出了一种冲桩系统改造方案,

Site characterization is fundamental to managing ground risks and optimizing opportunities.
It is subordinate to nearshore and offshore projects, selected here to mean projects for …

Deep seabed polymetallic nodule mining machines have to operate in extremely soft ocean
floor having soils of shear strength in the order of 1-3 kPa. The extent of sinkage and pullout …

The current approach for mining of Poly-metallic nodules at a water depth of 6000m uses a
tracked vehicle for locomotion on seabed. As the sea bed sediments are very soft clays, it is …
