... ABSTRACT: Offshore monopiles design requires the assessment of soil spatial variability within the foundation zone of influence. At wind farm scale, such assessment can be based on a site investigation strategy designed to include acquisition of geodata at nested location clusters. This paper...

... ABSTRACT: Ice, as sea ice or icebergs can pose a risk to seabed infrastructure. In the case of icebergs, this risk has been investigated by a number of workers and is reasonably well understood. However there has been little work performed to assess the risk sea ice poses. Sea ice is formed...

... related to seismic ground motion or progressive rock-mass degradation. This paper presents a study aimed at understanding how a quantitative boulder impact hazard assessment can be carried out in a probabilistic framework, modelling the physics of the phenomenon in a robust and realistic manner...

... of these trenchers are heavy, weighing several 10's of tonnes yet often designed to operate on clays of 10 kPa. Current assessment methodologies focus on the track area and the weight of the trencher, however, this ignores some key factors such as cutting forces for mechanical cutters, the effect of rut formation...

... Decommissioning of subsea rigid pipelines by partial or full removal is likely in many jurisdictions to adhere with international or local legislations and community expectations. Typically, a decision to do so follows environmental impact and risk assessments demonstrating options of reefing or in-situ...
