Atmocean and The Potential of Wave Energy – Part 2

December 13, 2014

Atmocean’s wave energy system is unique in that each array of fifteen seawater pumps located up to 2 miles offshore produces pressurized water transmitted in a seafloor hose to the onshore turbine operating a generator. By using and underwater compressed air energy storage system a dramatic reductions in the net cost and availability of grid-scale energy storage is reached. Storing air at hydrostatic pressure, in equilibrium with the surrounding water allows the use of thin-walled storage vessels, and simpler, more reliable compressors. A simple, proprietary reversible air compressor runs at near-constant temperature and the heat of compression is stored in water and is restored during expansion of the air.

Marine Turbines for Local FPSOs

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.

GE O&G has been awarded a contract valued at $160 million to supply gas turbine and compressor equipment by Petrobras Neatherlands BV (PNBV).The equipment will be deployed on two FPSOs (P-58 and P-62) for E&P in oil fields located in Brazilian offshore plays. This important $160 million contract is related to power generation and compressor equipment packages to be deployed on two Petrobras FPSO units slated to work the north side of the Parque das Baleias (Whale Park) O&G fields and at the Roncador field at the Campos Basin. These combined will support production of 360,000 barrels of oil per day. The FPSOs are scheduled to go online in 2013.
