STATEMENT OF WORK REQUIRED:

D

R

7.1 Perform detailed design of sonar gondola based on findings in ref 2.1.
7.1.1 Design shall incorporate all sensors listed in section 3.1.
7.1.2 Design shall incorporate allowances for future upgrades of transducers.
7.1.3 The design shall not exceed the minimum dimensions shown in ref 2.1 for extent below the baseline to ensure draft impact is minimized.
7.1.4 Consult as necessary w/ OEMs and NANCY FOSTER Survey department personnel:

7.1.4.1 Kongsberg POC – Travis Eliasen

([email protected])
7.1.5 Design shall be of sufficient detail such that a 3rd party fabrication contractor can successfully construct
gondola. Contact OEMs as necessary to obtain dimensions
