Tri-Suction Pile Caisson - Analysis of Soil-Structure Interaction

Offshore wind turbines are getting larger and are being installed in ever deeper waters. This requires increasingly stronger yet affordable foundations. The Tri-Suction Pile Caisson (TSPC) is a Wind Turbine Generator (WTG) foundation concept patented by SPT Offshore that requires a smaller amount of structural steel or concrete than a...

Seismic Response of Liquid Storage Tanks: A Mode-Matching Approach Considering both Fluid-Structure and Soil-Structure Interaction

Liquid storage tanks are used worldwide to contain liquids such as drinking water, fuel and chemicals. Loss of containment during a seismic event can add to an earthquake’s destructiveness by posing a fire hazard, spilling toxic substances or reducing the supply of drinking water. It is therefore important that they remain operational at a pre...

Assessment of Marine Pipelines Subjected to Impact from Dropped Objects

When damage assessment is needed for an operating pipeline due to impact with an accidentally dropped object, DNV standards treat this case with conservatism and thus fail to give a realistic estimation. Usually, damage is measured as the dent deformation that the pipeline will experience. Depending on the size of the dent, leakage, rupture or...
