The term “semi-submersible platform” refers to a type of specialised marine vessel used in offshore operations as heavy lift cranes, safety vessels, hydrocarbon production platforms, and offshore drilling rigs. Better than drillships, they have excellent ship stability and seakeeping.
The majority of a semi-submersible buoyancy is provided by ballasted, watertight pontoons situated below the ocean’s surface and by wave action. Pontoons and a working deck are connected by structural columns. Due to the design’s excellent ship stability, it is possible to position the working deck above sea level, keeping it far from the waves.
The Global Semi-submersible drilling platform Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The Argyll field, based in the central North Sea in about 80 metres of water, saw the start of the first oil and gas extraction from a floating platform.
The platform was a second-generation semisubmersible Offshore Drilling Unit that had been renovated. As industry moved farther offshore in search of new oil and gas sources to replace declining output from shallow water fields, the use of floating production systems increased.
Deepwater operators are increasingly turning to floating production systems (FPSs), particularly semi submersible production platforms, to advance their field development projects as the offshore industry starts to recover from the downturn.
There may be up to five more FPS field developments in the Gulf of Mexico, according to some projections.In 225 km of offshore Mississippi Canyon water, in depths varying from 1,670 m to 2,300 m, is where the Na Kika development is located.
After the finding was made it started to produce the first purpose-built FPS in the GoM. With numerous technological firsts and deepwater records established, it was a ground-breaking accomplishment. Six widely separated oil and gas fields and 10 subsea wells made up the initial part of the development.
With offset distances varying from 8 km to 42 km, the wells are connected back to the FPS, which is positioned in the middle. Despite the fact that each of the six fields is undeveloped, they together have an estimated 300 MMboe in viable reserves.
