NOAA Ships Reduce Emissions

The National Oceanographic and Atmospheric Administration (NOAA) has two new ships that will use technology provided by Siemens Energy to enable additional emissions and fuel savings.

The new ships, named the Oceanographer and Discoverer, will support various missions, including general oceanographic research and exploration, climate and ocean ecosystem studies, and worldwide ocean survey and data collection.

The newly implemented technology will lead to fuel savings of 15,000 gallons per year for each vessel, resulting in a reduction of approximately 5,700 tons of CO2. The two NOAA vessels are scheduled to enter operation in 2024 and 2025 respectively. Each will host a crew of 20 and can accommodate up to 28 scientists.

Siemens Energy will equip both ships with SiSHIP Blue Drive PlusC™ advanced diesel-electric propulsion systems and BlueVault™ Battery Storage Solutions. The combination of technologies will enable additional fuel savings and emissions reductions by allowing NOAA to optimize loading on variable speed diesel engines. It will also reduce maintenance associated with the engines.

“The NOAA NAV Variant is truly the result of an intense, collaborative effort by the Thoma-Sea Marine team, analyzing and implementing the best solutions brought by the shipyard, our design agent (TAI), Siemens Energy and others,” said Walter Thomassie, managing director, Thoma-Sea Marine Constructors, L.L.C. in a statement. “As the first shipyard to install and commission the Siemens Energy Blue Drive PlusC™ advanced diesel-electric propulsion systems in the United States, Thoma-Sea immediately recognized Siemens Energy was able to optimize the system according to our specifications to further enhance the vessel’s capabilities and efficiencies.”

The SiSHIP Blue Drive PlusC™ diesel propulsion technology has been installed on more than 80 marine vessels worldwide, including the world’s first all-electric car ferry and the world’s largest cruise PAX ferry.
