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 .
The Lun-A (Lunskoye-A) platform, located off the north eastern coast of Sakhalin Island and is a concrete gravity base substructure (CGBS).. An oil platform (also called an oil rig, offshore platform, oil production platform, etc.) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed.
An offshore environment has several implications for geotechnical engineering. These include the following: [1] [4] Ground improvement (on the seabed) and site investigation are expensive. Soil conditions are unusual (e.g. presence of carbonates, shallow gas). Offshore structures are tall, often extending over 100 metres (330 ft) above their ...
Suction caissons have been installed in most of the deep water oil producing areas around the world: The North Sea, Gulf of Mexico, offshore West Africa, offshore Brazil, West of Shetland, South China Sea, Adriatic Sea and Timor Sea. No reliable statistics have been produced after 2002, but the use of suction caissons is still rising. [2]
This type of scaffold is generally used where extensive versatility is required. In many countries, it is common in construction . Horizontal tubes and walking decks can be placed at any height along the vertical tube (as permitted by engineering constraints), and vertical tubes, or legs, can be spaced at any distance apart, up to the maximum ...
A submarine pipeline (also known as marine, subsea or offshore pipeline) is a pipeline that is laid on the seabed or below it inside a trench. [ 1 ] [ 2 ] In some cases, the pipeline is mostly on-land but in places it crosses water expanses, such as small seas, straits and rivers. [ 3 ]
Underwater construction is industrial construction in an underwater environment.It is a part of the marine construction industry. [1] It can involve the use of a variety of building materials, mainly concrete and steel.
Hydrographic survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore wind farms, offshore oil exploration and drilling and related activities. Surveys may also be conducted to determine the route of subsea cables such as telecommunications cables, cables ...
