The Pelamis P2 is the second-generation Pelamis Wave Energy machine and includes a number of significant design improvements. The P2 design has been sold to utility customers E.ON and ScottishPower Renewables and are currently being tested for a number of commercial scale projects. At 180m long, 4m diameter and weighing around 1350 tons (mostly sand ballast), the P2 Pelamis is wider, longer and heavier than the P1 design machine. This allows the Pelamis to capture more energy while substantially reducing the cost per MW. Comprised of five tubes with four joints, the P2 has an extra tube section and an extra power module. An improved power take off system for the P2 allows higher efficiencies, enhanced control resolution and increased reliability.

Petrobras has started the tendering process for machinery for the 28 pre-salt FPSOs to be built in Brazil. Hopes are that such a large order will attract the limited number of marine turbine manufacturers to set shop in Brazil.The tendering process is expected to involve up to 128 units, including marine turbines, generators and compressors. Since there a but a handful of heavy marine turbine manufacturers in the world and with the local content policy demanding around 70% local content from shipboard equipment manufacturers, Petrobras hopes to attract some of the larger global marine turbine, generator and compressor suppliers to install manufacturing plants in Brazil.
