One of the large International Oil Companies considered placing a liquefaction plant on a gravity based structure (GBS) in the shallow waters of the Nigel delta, south of the Brass River mouth. 

The marine environment is challenging in that area: seabed soils consist of under-consolidated alluvial deposits and there is a frequent swell with a wave period of up to 17 seconds coming in from the Bay of Guinea. 

Scope of Work: Estimated the bearing capacity and settlement for GBS dynamic effects, namely resonance due to low foundation eigenfrequency. Provided recommendations for soil improvement.

Project executed while Jesper Damgaard was employed by HR Wallingford.
