What is a TLP in oil and gas?
A tension-leg platform (TLP) or extended tension leg platform (ETLP) is a vertically moored floating structure normally used for the offshore production of oil or gas, and is particularly suited for water depths greater than 300 metres (about 1000 ft) and less than 1500 metres (about 4900 ft).
What is a TLP facility?
The term ‘Term Loan B’ or ‘TLB’ is used in the lending market to refer to a tranche of senior secured credit facilities made available to a borrower that is designed to be syndicated in the institutional loan market.
Would you call TLP tendons mooring lines?
A Tension Leg Platform (TLP) is a vertically moored compliant platform. The floating platform with its excess buoyancy is vertically moored by taut mooring lines called tendons (or tethers).
How does a tension leg platform TLP work?
How Does a Tension Leg Platform (TLP) Work? The buoyancy of the facility’s hull offsets the weight of the platform, requiring clusters of tight tendons, or tension legs, to secure the structure to the foundation on the seabed. The foundation is then kept stationary by piles driven into the seabed.
How does a semi-submersible oil rig work?
Semi-submersibles are the choice for drilling from a floating position, due to the deep water depths. Semi-submersible (“semi”) rigs float like a ship while being towed into position, where their pontoons can then be flooded, partially submerging the rig.
What is the purpose of mooring lines?
The main function of mooring lines is to hold a ship fast to her berth against the effects of wind and current or other forces. If the mooring lines are adjusted properly, wind or current loading on the lines is a static load.
What is tether in offshore?
Dynamica Tethers are reliable synthetic subsea mooring systems that secure risers, umbilicals and Mid-Water Arches connected to production systems, ensuring smooth flow of oil to processing facilities. Dynamica Tethers can be manufactured as either fibre or rope Tether depending on the required strength and length.
What is the difference between FSO and FPSO?
The difference between the systems is that the FPSO is also directly connected with the oil drilling while the FSO is only concerned with storage. The most advanced technology for deep sea oil extraction opens the way for oil companies to venture further into ever more extreme conditions in the search for oil.
Who builds FPSOs?
The first oil FPSO was built in 1977 on the Shell Castellon field, located in the Spanish Mediterranean. Today, over 270 vessels are deployed worldwide as oil FPSOs. On July 29, 2009, Shell and Samsung announced an agreement to build up to 10 LNG FPSOs, at the same Samsung Yard.
