The Future of Offshore Foundations

  • The future of offshore hydrocarbon exploration and development lies in deeper waters.
  • Production will require very large structures or innovative seabed completions.
  • This will result in greater challenges for the design of offshore foundations and anchors.

Major geotechnical challenges are associated with the design of foundations and anchors for offshore oil and gas developments. As this industry continues to move further offshore and into deeper waters, design requirements increase and ground conditions become more difficult. Advanced Geomechanics is equipped to meet these challenges.

In some circumstances, traditional piled foundations can prove to be an uneconomic solution.

A deep skirted shallow foundation, commonly referred to as a 'bucket' foundation, can be a viable solution in such cases.

A schematic diagram of a bucket foundation is presented in the upper figure, whilst the lower figure shows the pore pressure response in the soil beneath and around the foundation, caused as a wave passes through the platform.

Advanced Geomechanics has the essential expertise to provide robust designs of such novel foundation systems, for all soil types including calcareous soils. Advanced Geomechanics prides itself on its knowledge of the engineering properties of calcareous soils and the unique design approaches associated with these extraordinary soils which have been problematical in the past.
