Title: Lifting objects off the seabed
Abstract:
Most of us have experienced the difficulty of lifting our shoes up from muddy ground (the quintessential ‘stuck in the mud’). This phenomenon is analogous to lifting objects off the seabed. Deep understanding this problem is the scientific basis for a variety of offshore applications, such as (1) retrieval of oil and gas infrastructure sitting on the seabed for decommissioning, repairing or even repositioning; (2) marine salvage; and (3) securing submarine foundations against lifting away under severe storm conditions.
This seminar reviews the speaker’s research work in the past years in investigating the process of lifting skirted foundation off the seabed. Essentially, the talk will concentrate on (1) the effect of uplifting rate on the resistance capacity; (2) sustained uplifting loading for bucket foundations; (3) developing numerical structure-soil interface to facilitate numerical uplifting modelling.
