Subsea 7 is to build and operate three flexible pipe-lay support vessels (PLSV) for Petrobras under three five-year contracts worth about US$1.6 billion.
The contracts include project management, engineering and installation of flowlines, umbilicals and equipment supplied by Petrobras.
The three new PLSVs will be based on similar design to the Seven Waves, and will be constructed in Holland at the IHC Merwede shipyard.
The vessels are scheduled to be delivered in Q3 2016, Q4 2016 and Q2 2017 respectively.
They are designed for operation in water depths of up to 3000m, and will be equipped with a pipe-lay system for installing flexible flowlines and umbilicals, including a lay system tower with 550 tonnes top tension capability, twin underdeck baskets capable of storing up to 4000 tonnes of flexible flowlines and two state of the art ROVs.
The total cost of the three vessels, including inventories, commissioning and mobilization to Brazil, is approximately US$950 million.
