The complete paper is a comprehensive discussion of the development and deployment of the tension leg platform (TLP), one of the four major platform types that also include floating production, storage, and offloading (FPSO) vessels; semisubmersible floating production systems; and spar platforms. The Ursa tension leg platform is an oil platform with a tension leg structure located at 28°09′14″N 89°06′13″W / 28.154027°N 89.103553°W / 28.154027; -89.103553 about 130 miles (210 km) southeast of New Orleans in the Gulf of Mexico. P-61 Tension Leg Wellhead Platform (TLWP) Technology The combination of oil reservoirs with an API gravity ranging between 14 and 17, and being in deep water, makes developing the Papa-Terra field one of the most complex projects ever conceived by Petrobras, requiring several innovative solutions to be incorporated, including the P-61 itself. Paper presented at the Offshore Technology Conference, Houston, Texas, May 1988. doi: https://doi.org/10.4043/5637-MS. The PelaStar tension leg platform (TLP) technology enables a scalable, integrated blade tip-to-seabed solution that minimizes the cost of energy in deepwater offshore wind sites. Anders Myhr, NMBU(UMB) The small motions of the tension-leg platform benefit the system energy capture while limiting inertial loads placed on the rotor's tower and blades. P-61 Tension Leg Wellhead Platform (TLWP) Technology The combination of oil reservoirs with an API gravity ranging between 14 and 17, and being in deep water, makes developing the Papa-Terra field one of the most complex projects ever conceived by Petrobras, requiring several innovative solutions to be incorporated, including the P-61 itself. By opting for a Tender Assisted Drilling approach to drill and complete the Well instead of fabricating a permanent rig package, the project could save capital expenditure by building a comparatively smaller TLP. Malikai Project made a cost-driven decision to adopt the 2-body TLP-DTV configuration to Drill and Complete the Wells offshore. Initial feasibility studies for the STLP focused on a design for 4000 ft. (ca. As the name indicates, this type of rig is located on a fixed structure previously installed at the well location.

Out of the total project cost 55% was dedicated to the fabrication and installation of the hull, deck facilities and pipelines. It has a total height from the seabed to its top of 4,285 feet (1,306 m).[1]. The structure is held in location using thick steel pipes called Tendons (generally 24-42 inch diameter, 1 inch thick). An example of that would be a conventional column hull, 4 Leg configuration, with 2 Tendons per Leg. The tension leg platform designed by Shell will offer a huge deck, large enough to process the crude on site, with production coming from a six well subsea development. Cost of Energy Reduction for Offshore Tension-Leg Platform (TLP) Wind Turbine Systems through Advanced Control Strategies for Energy Improvement T25, DE -EE0005494.0009 Dhiraj Arora GE Renewable Energy (presented by Brad Ring and Gary Norton, DOE) This structure is then anchored to the seabed with tendons. During this initial phase, a tension leg platform (TLP) with a hull made of multiple cylindrical columns was identified as the most promising selection from a cost … Whereas the conventional TLP mooring stiffly restrains all vertical motions, the central tension-leg of the STLP suppresses only heave motions. The tension leg platform consists of five modules weighing 11,500t. •The Tension Leg Platform •Less mature technology •Potential for Lowest Cost of Energy •Technical Challenges that need solutions •ETI Push for Ambitious Goal •Take Concept through Front-End Engineering Design (FEED) for a FULL SCALE Demonstration (6MW) Project Offshore •Engineers working with Engineers 3 In this figure, the amount of tension variation due to pitch and roll restraint is compared to fluctuations due to heave alone for a centrally located tendon. Since the tendons do not restrain pitch or roll, total dynamic tension variation is reduced, as can be seen in Figure 2.
