... a typical 12t Bruce GP drag embedment anchor performs in sandy soil. Initial tests in loose and medium-dense soil conditions identify the ultimate holding capacity (UHC) of the anchor. Subsequent tests were then conducted in which the anchors were dragged to 60% of the UHC, to mimic current installation...

... ABSTRACT: The use of vibro-driving for the installation of large diameter monopiles is investigated in soil conditions consisting primarily of very dense sand and sand/silt mixtures. A feasibility study of vibro-driveability installation has been performed on a monopile geometry that has been...

ABSTRACT: One of the challenges within offshore renewables projects is the integrated characterization of soil conditions, to ensure safe operations and installation of e.g., monopiles using jack-up rigs. Importantly, development areas often have experienced a complex geological history, which...
