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 …

Aug 25, 2022 · A tension-leg platform (TLP) or an extended tension leg platform is a vertically anchored floating structure that is often utilized for offshore oil or gas production in water depths greater than 300 meters (about 1000 feet) but less than 1500 meters (about 4900 ft).

Three TLP hull designs are commonly used on the U.S. OCS: conventional (large), MODEC's MOSES (Minimum Offshore Surface Equipment Structure) and SeaStar. TLPs are generally limited to water depths of 6,000 feet and less.

May 3, 1999 · This paper describes the design, fabrication and transportation of the 28,500mt Ursa TLP hull. The process involved a fast track design performed in the USA while fabrication of the hull was underway in Italy.

Oct 15, 2012 · In this study, a new multi-column TLP foundation (WindStar TLP) was developed for the NREL 5-MW offshore wind turbine according to site-specific environmental conditions, which are the same as the OC3-Hywind (NREL) conditions.

Jul 9, 2022 · In the present study, a fully coupled TLP hull-TTR system for hydrodynamic numerical simulation is established. A specific hydraulic pneumatic tensioner is modeled by considering 4 cylinders. The production TTR model is stacked up by specific riser joints.

Oct 29, 2013 · An overview and description of TLP hull configurations. Basic hull and tendon design considerations. A chronology of TLP designs, applications and contracting strategies. The evolution of top tension riser (TTR) designs. The evolution of TLP tendon and foundation systems. Important updates in codes and standards used for TLP design and construction

Mar 25, 2016 · The purpose of this study was to develop a methodology for the optimization of TLP hull sizing. An optimization algorithm was used, but the study took a practical approach, and hydrodynamic, global performance, structural strength, …

Apr 1, 2016 · This paper provides an optimization method for TLP in the consideration of hull form and tendons. A modeling and assessment procedure of TLP is developed to formulate the optimization problem. A total eight different optimum solutions are compared for their validity.

Mar 22, 2016 · The construction of the Malikai Tension Leg Platform (TLP) hull involved the fabrication and assembly of sixteen (16) blocks with nodes, columns and pontoons ranging in weight from 300 MT to nearly 1,000 MT.
