An industry sponsored study on the design and analysis of deepwater anchors in soft clay was completed in 2003, where NGI participated together with OTRC and Centre for Offshore Foundation Systems (COFS) in Australia. The overall objective was to provide the API Geotechnical Workgroup (RG7) and the Deepstar Joint Industry Project VI with ...
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
Platforms offshore Mexico. Offshore geotechnical engineering is a sub-field of geotechnical engineering. It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea. [1] Oil platforms, artificial islands and submarine pipelines are examples of such structures. The seabed has to be ...
Concrete offshore structures are highly durable, constructed of low-maintenance material, suitable for harsh and/or arctic environment (like ice and seismic regions), [1] can carry heavy topsides, may be designed to provide storage capacity, can be suitable for soft ground and are economical for water depths larger than 150 m. Most gravity-type ...
NIOT has been developing several offshore components for various programs like desalination, mining, data buoys etc. These include pipelines/risers, moorings in deep water for small buoys as well as large vessels. The need for developing several offshore components has been felt for most of the projects handled in NIOT. The group addresses such ...
Early deployments of offshore wind power turbines used these structures. As of 2010, 14 of the world's offshore wind farms had some of their turbines supported by gravity-based structures. The deepest registered offshore wind farm with gravity-based structures is the Blyth Offshore Wind Farm, UK, with a depth of approx. 40 m. [3]
Offshore embedded anchors are anchors intended for offshore use that derive their holding capacity from the frictional, or bearing, resistance of the surrounding soil, as opposed to gravity anchors, which derive their holding capacity largely from their weight.
Offshore construction is the installation of structures and facilities in a marine environment, usually for the production and transmission of electricity, oil, gas and other resources. It is also called maritime engineering .
