Tension Leg Platform TLP
rating: 0+x

TLP platforms are permanently moored by tethers or tendons grouped at each of the structure's corners. A group of tethers is called a tension leg. A feature of the design of the tethers is that they have relatively high axial stiffness, eliminating virtually all the vertical motion of the platform. This allows the platform to have the production wellheads on deck, and dry trees connected directly to the subsea wells (by rigid risers) instead of on the seafloor.

The key characteristics of a TLP include:

  • Excellent motion characteristics
  • Capability to support Top Tensioned Risers (TTRs) and dry trees
  • Capability to support both production and drilling facilities
  • Large water depth range and capacity
  • No storage
  • Integration and commissioning inshore

The deepest (E)TLPs measured from the sea floor to the surface are:[3]
