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.

NOAA Ship Thomas Jefferson 2016 SAT

Executive Summary

A Kongsberg EM2040 multibeam and an EM710 MKII multibeam were installed aboard NOAA Ship Thomas Jefferson during an extended shipyard period at the Coast Guard yard in Curtis Bay in Baltimore, MD during the spring and summer of 2016. After a short stay at the Atlantic Marine Operations Center in Norfolk, VA, the ship proceeded with acceptance testing of the new survey systems in the areas between Norfolk and Hudson Canyon during the third week of October, 2016, with the assistance of Office of Coast Survey and Kongsberg personnel.


RV Bat Galim 2016 System Review

From January 31st to February 4th, 2016 a Shipboard Acceptance Testing (SAT) was conducted on the R/V Bat Galim, owned by the Ministry of National Infrastructures, Energy and Water Resource of Israel and operated by Israel Oceanographic and Limnological Research, on the newly installed Kongsberg Maritime (KM) EM302 (30 kHz) and EM2040 (200 kHz, 300 kHz, and 400 kHz) multibeam echosounders. These systems were thoroughly reviewed for system geometry, calibration, configuration, and performance during this acceptance period. Documented in this report are:


RV Bat Galim 2016 Acoustic Test Report

During the at-sea test on BAT GALIM, the main objective was to determine ship acoustic characteristics and to assess potential impacts to sonar performance from all acoustic sources. The primary sonars of interest were the newly installed Kongsberg EM 302 and EM 2040 multibeam systems. The following evaluations were accomplished as part this testing:

  1. The overall noise levels of BAT GALIM were measured and characterized with special test sensors and internal noise routines inherent in the Kongsberg sonars.
  2. Propeller cavitation characteristics were assessed.
