NOAA Ship Fairweather Launch 2017 SAT

Executive Summary

We installed four Kongsberg EM2040 multibeam echo sounders, one on each of Fairweather’s
hydrographic survey launches during the spring of 2017 in Newport, OR. We accomplished the test and
qualification of these systems on Puget Sound from May 22 through May 26. Conditions were generally agreeable for testing with some wind driven chop potentially affecting a limited set of noise tests. All systems were successfully integrated and measured performance was in compliance with vendor specifications and suitable for conducting NOAA hydrographic surveys.

Multibeam System:


Executive Summary
A Kongsberg EM710 multibeam echosounder was installed on the NOAA Ship Fairweather by Bay Ship and Yacht Co. of Alameda, CA in December, 2014. This mapping sonar replaced a Reson 8160 and a Reson 7111.

The performance of the EM710 was evaluated during sea‐trials from 9 February to 13 February, 2015. The performance of this system as installed and integrated meets the manufacturer specification and is adequate to meet the intended charting mission. All modes of operation were tested between 50 and 500 meters.
