Alternate Foundation Concepts for Offshore Jackets in Calcareous Soils
Offshore Technology Conference Asia, 2022Abstract Calcareous soil type is found at many locations, requiring careful selection of foundation type. Calcareous soil is mostly or partly composed of calcium carbonate in the form of lime or chalk derived from the underlying chalk or limestone rock.

Novel Foundation Concept for a Jacket Finding Its Place
Offshore Technology Conference, 1993A major departure from traditional foundation practice for steel jackets has been developed based on the experience with skirts for huge concrete gravity platforms. The method, using plate-skirt foundations or perhaps better described as “skirted mudmats” or skirtpiles, will provide bearing capacity for compressive loads in the same way as gravity ...

Integrated optimal design of jackets and foundations
Marine Structures, 2018Abstract The article proposes a method for integrated design of jackets and foundations using numerical structural optimization. Both piles and suction caissons are examined in both clayey and sandy soil, and several design procedures are taken into account.

Foundation Engineering of Offshore "Jacket" Structures
Contemporary Topics in Deep Foundations, 2009Jackets are marine structures commonly utilized in civil — offshore construction practice. Foundation engineering of jackets requires exceptional design and construction skills to cope with adverse geotechnical conditions and extreme operational and environmental loads. A synopsis of deep foundation design and practice employed in jacket engineering is

Framework for Multi-Level Optimisation of Offshore Wind Jacket Foundations
ASME 2023 5th International Offshore Wind Technical Conference, 2023Abstract This paper presents Wood Thilsted’s in-house developed framework MORPHEUS for structural optimization of jacket structures. The approach is based on a hybrid model consisting of 3D Timoshenko beam elements, combined with stiffness and mass representation of non-trivial details like the transition piece (TP) and tubular joints ...

Load analysis and comparison of different jacket foundations
Renewable Energy, 2013Abstract As a country mostly surrounded by water, Korea plans to build a massive offshore wind farm off the west coast by 2019. Due to the different seabed condition, wind turbine with jacket foundation is considered as a suitable choice for the intermediate water depths so far. And preliminary work is necessary for the wind turbine manufactures.

Jacket Performance due to Foundation-Degraded Response
Offshore Technology Conference, 1992ABSTRACT This paper is concerned with the prediction of the ultimate capacity of piles driven into clays to support offshore production and drill i ng facil it i es. Such pil es are generally long and flexible and oftenarranged in clusters around the jacket corners.

Risk of Foundation Failure of Offshore Jacket Piles
Offshore Technology Conference, 1996Abstract The paper discusses the application of reliability theory to offshore foundation piles. Tire theoretical risk of failure for piles is computed for a range of realistic soil and loading conditions. The reliability analyses are updated in the light of long term field experience and the results used to comment
