NCE Receives ABS Certification
Noise Control Engineering Inc. of Billerica, MA has received external specialist certification in Ambient Environmental Testing from the American Bureau of Shipping (ABS). NCE is the only company in North America and only one of four companies in the world to acquire such a certification. The certification includes measurements of noise, vibration, lighting, temperature and relative humidity. In order to receive the certification, NCE was required to develop detailed procedures for testing the parameters listed above, along with a quality assurance plan and instrument calibration procedures. NCE has always laboratory calibrated its field instrumentation on an annual basis. However, a more rigorous methodology and process had to be put in place for ABS.
Ship Noise Guide Updated
Controlling shipborne noise is always a concern for vessel designers, builders and outfitters. The two most widely distributed documents are IMO's Resolution A.468(XII), "Code on Noise Levels Onboard Ships," issued in 1981 and the USCG's Navigation and Vessel Inspection Circular (NVIC) 12-82, "Recommendations on Control of Excessive Noise," issued in 1982. These two documents generally discuss methods to reduce shipboard noise, recommend noise limits and describe how to measure noise on ships. One year after the USCG issued the NVIC 12-82, a group of acoustical engineers from the consulting firm of Bolt Beranek and Newman (BBN), completed a report that is not as well known, which is still available from SNAME.
FRV's Get Advanced Noise Control
The engineering consulting firm, Noise Control Engineering has just received a subcontract from Friede-Goldman Halter for the engineering and acoustical design services on NOAA's new Fisheries Research Vessel, the FRV-40. The ship will be designed to quietly perform fish stock assessment studies in the open ocean. According to Mr. When completed the FRV-40 will be one of the most sophisticated and quietest vessels of its type. Noise Control Engineering or NCE will be a key participant in the detail design of the vessel along with Halter Marine's Engineering office in Gulfport, Mississippi. NCE will be preparing numerous acoustic design studies and analysis. The firm is responsible for noise control treatment recommendations and their design.
