How does a tension leg platform work?

How Does a Tension Leg Platform (TLP) Work? A type of floating production system, tension leg platforms (TLPs) are buoyant production facilities vertically moored to the seafloor by tendons. While a buoyant hull supports the platform’s topsides, an intricate mooring system keeps the TLP in place.

What is 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 Sea Star platform?

The SeaStar platform is a small TLP with a single surface-piercing column. The tension-leg mooring system suppresses nearly all vertical motions. This type of mooring configuration makes it possible to have a single, stable column piercing the surface of the water with a small water plane area.

What is a fixed offshore platform?

A fixed platform is a type of offshore platform used for the extraction of petroleum or gas. These platforms are built on concrete and/or steel legs anchored directly onto the seabed, supporting a deck with space for drilling rigs, production facilities and crew quarters.

What is the meaning of TLP?

Introduction. The Traffic Light Protocol (TLP) was created in order to facilitate greater sharing of information. TLP is a set of designations used to ensure that sensitive information is shared with the appropriate audience.

How does a spar platform work?

How Do Spars Work? A floating platform alternative that can support drilling, production and storage operations, the spar consists of a large vertical cylinder bearing topsides with equipment. Atop the spar hull sits the topsides, which can be comprised of drilling equipment, production facilities and living quarters.

What does TLP mean?


Acronym Definition
TLP Transaction Layer Protocol
TLP Transactional License Program
TLP The Learning Partnership
TLP Technology Leadership Program (various organizations)

What is the difference between FPSO and FSO?

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.

What are the 7 varieties of offshore platforms?


  • Fixed platforms.
  • Compliant towers.
  • Semi-submersible platform.
  • Jack-up drilling rigs.
  • Drillships.
  • Floating production systems.
  • Tension-leg platform.
  • Gravity-based structure.

How much does it cost to build an offshore platform?

The average cost for offshore rigs can be as much as 15 to 20 times greater than the average cost for land rigs. The least-expensive offshore rigs typically cost nearly $200 million. The average price for offshore oil-drilling rigs is approximately $650 million.

What does TLP mean in texting?

TLP. Top Level Post (in message threads) TLP.

Where was the first tension leg platform built?

The first tension leg platform was built for Conoco’s Hutton field in the North Sea in the early 1980s. The hull was built in the dry-dock at Highland Fabricator’s Nigg yard in the north of Scotland, with the deck section built nearby at McDermott’s yard at Ardersier. The two parts were mated in the Moray Firth in 1984.

How does a Tension Leg Platform ( TLP ) work?

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). The structure is vertically restrained precluding motions vertically (heave) and rotationally (pitch and roll).

How many megawatts can a tension leg platform generate?

In contrast, TLP installation was calculated to cost a third as much. TLPs float, and researchers estimate they can operate in depths between 100 and 650 feet (200 m) and farther away from land, and they can generate 5.0 megawatts.

Where are the tension leg platforms in the Gulf of Mexico?

Conoco authorised the design of a small wellhead platform (TLWP) in 1986 and the unit was installed in the Jolliet field (1755 ft or 535 m water depth) in 1988. Other units to follow Jolliet in the Gulf of Mexico are Shell’s deepwater TLPs.
