Birdon Group has brought Noise Control Engineering on board to assist with the acoustic design of 27 Waterways Commerce Cutters (WCCs)—a fleet of all-new vessels commissioned by the US Coast Guard to replace the current fleet of aging inland tender vessels. The WCCs will maintain and protect the inland and inter-coastal waterways that comprise the US Marine Transportation System. NCE will help Birdon meet the noise and vibration goals established for the WCCs through detailed analyses, development of the acoustic design, and compliance testing once the vessels are built. We are grateful to be a part of this major project for an outstanding new client and look forward to seeing the first WCC in service. #USCG #noisecontrol #shipbuilding #acousticalengineering

Jesse Spence, president of Noise Control Engineering, is presenting at the SNAME Maritime Convention next week. Don’t miss his session with US Coast Guard Staff Engineer Carol Yin on Tuesday afternoon, which will discuss new concepts and design approaches to reducing underwater radiated noise and greenhouse gas emissions. If you’re interested in getting in touch during the conference, please reach out to us at inquiries@noise-control.com. We hope to see you there! #SMC2024 #SNAME #noisecontrolengineering #maritimeindustry

Noise Control Engineering is supporting a study for the Maritime Administration (MARAD)'s META program to analyze the potential for underwater noise reductions through the use of battery-electric propulsion systems on vessels. For the study, our team collected underwater noise data from three tugs in San Diego Harbor: two with conventional diesel-geared propulsion and a new vessel with battery-electric propulsion. The data will be processed to commercial standards, allowing for an overall assessment of noise and comparison to other vessels for a range of operating conditions. We are also identifying the sources of noise on board the tugs and how/why battery-electric vessels may be quieter than their diesel-geared counterparts. NCE is proud to be part of this effort to assess the co-benefits of low-emission designs and their potential to reduce impacts to marine life. #noisecontrolengineering #sustainable #underwaternoise

Congratulations to Crowley on the successful delivery of the eWOLF: the first all-electric, ship assist harbor tugboat in the US. Based in the Port of San Diego, the 82-foot tug features a design that allows for fully electric and emissions-free operations while maintaining the capabilities of a traditional ship assist tug. Noise Control Engineering assisted Crowley during the vessel’s design, predicting noise and vibration levels and providing recommendations for mitigation to ensure compliance and help Crowley meet their goals. NCE also performed noise and vibration testing during sea trials following construction at Master Boat Builders, Inc. We are fortunate to have contributed to this project and happy to work with Crowley to enhance sustainability in the maritime industry. #noisecontrolengineering #noiseandvibrationtesting #tug #sustainable

Noise Control Engineering is proud to be supporting Chantier Naval Forillon with the detail design and construction of the Canadian Coast Guard/Garde côtière canadienne’s first hybrid-electric vessel! The Near-Shore Fishery Research Vessel (NSFRV) is designed to reduce carbon emissions, fuel consumption, and underwater radiated noise. NCE is working with the shipyard on noise and vibration analyses and will perform testing during sea trials. The addition of this vessel to the coast guard represents an important move towards a more sustainable fleet and fulfilling Canada’s ambitions of a zero-emissions future. #noisecontrolengineering #noiseandvibrationdesign #underwaterradiatednoise

Seaspan ULC is designing and building a new class of multi-purpose vessels (MPVs) at Vancouver Shipyards for the Canadian Coast Guard/Garde côtière canadienne and Noise Control Engineering is assisting with acoustics. Our work began during the basic design phase with noise and vibration predictions—a forecasting method which gives our client the opportunity to modify the design to correct any noise and vibration issues before the MPVs are built. As the design progresses, NCE is updating prediction results and providing treatment and outfitting recommendations. These noise control efforts will enable greater comfort, communication, and quality of life on board these versatile ships as they maintain Canada’s maritime corridors and provide emergency response throughout the region. #noisecontrolengineering #noiseprediction #acousticdesign #shipbuilding

We are proud to announce that Noise Control Engineering has been awarded Small Business Technology Transfer (STTR) program funding to develop our semi-empirical Bayesian helicopter noise source modelling software. At the nexus of machine learning and aeroacoustics, this tool will allow military and commercial flight planners to optimize flight paths quickly and accurately and can be utilized for other rotating machines, such as marine propellers and wind turbines. Phase I of the project is expected to be completed this summer and the STTR funding will help us continue to develop this convenient tool for commercial and military use. #noisecontrolengineering #airbornenoise #STTR

Noise Control Engineering is conducting a study for the Maritime Administration (MARAD)’s META program in Casco Bay, Maine that will help assess the potential for reduced underwater noise from vessels utilizing hybrid-electric power. For the study, our team is comparing the underwater noise generated by two Casco Bay Lines ferries: the conventional diesel-geared M/V Machigonne II and the newly built, battery-electric M/V Battery Steele. The data we collect will be used to identify how future power generation systems designed to reduce greenhouse gas emissions can be implemented aboard vessels to lower the impact of underwater noise on marine life. #underwaternoise #radiatednoise #noisecontrol Photo by Casco Bay Lines

Underwater radiated noise (URN) produced by commercial ships and its impact on marine life is a rising concern that may be confusing for many shipowners. However, devising solutions doesn’t have to be complicated or costly. In this month’s issue of Maritime Reporter, Noise Control Engineering President Jesse Spence discusses the importance of considering URN during the early phases of vessel design to ensure the most effective noise-reducing technologies are selected and will mesh with other non-acoustical design goals.
