Canadian Coast Guard Multi-Purpose Vessel Noise and Vibration Engineering

Seaspan ULC is designing and building the first in a new class of multi-purpose vessels (MPVs) at Vancouver Shipyards for the Canadian Coast Guard. Noise Control Engineering is assisting with the design of the vessel’s acoustics, identifying necessary treatment approaches and construction details. The new MPVs will be Polar Class 4 vessels measuring 328 feet long and nearly 67 feet wide, with accommodations for up to 50 people.

NCE’s work began in 2023 during the basic design phase with noise and vibration predictions—a forecasting method that 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, we update our models and prediction results and provide 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. We expect to provide continued guidance on treatment installation details during construction, along with construction inspections to identify potential items that can defeat the intended treatments. Finally, we would provide verification testing during sea trials to show compliance with the vessel’s noise and vibration requirements.
