McDermott installs P-61 tension leg wellhead platform for Papa Terra fieldNews // April 10, 2014
McDermott International has completed the installation of the P-61 tension leg wellhead platform (TLWP) for the PPT BV Joint Venture, consisting of Petrobras and Chevron. Once fully commissioned and operational, the project will be the first use of dry-tree floating technology offshore Brazil and the first Tension Leg Platform installation offshore South America.
The contract was awarded in 2010 to FloaTEC Singapore Pte Ltd (FloaTEC Singapore), a joint venture between subsidiaries of Keppel FELS Ltd and McDermott.
Topsides engineering was executed by McDermott in Houston and constructed in Singapore by Keppel FELS, and fabrication of the piles and tendons was provided by McDermott’s fabrication facilities. The hull was designed by FloaTEC in Houston and fabricated in Brazil by Keppel FELS at its BrasFELS yard. The topsides and hull were then integrated at BrasFELS using the float over method.
The McDermott team was instrumental in providing float-over support and executing the offshore transportation and final installation of the TLWP offshore Brazil. The project was carried out with significant technical contribution by Chevron to the TLWP design, construction and installation. Commissioning of the platform continues, under the expertise of the FloaTEC project team.
Using the Derrick Barge 50 (DB50) to install the tendons, McDermott successfully completed its offshore campaign without a single Lost Time Incident.
Recent enhancements to the DB50 include a new state-of-the-art switchgear and power management system with an upgraded level of auxiliaries resulting in improved reliability and stationkeeping.
