Page 36: Inspecting And Cleaning The Transducer Face
Context During normal use, the transducer is subjected to biological fouling. If this marine growth is excessive, it will reduce the performance of the EM 712. Whenever opportunity arise, typically when the vessel is dry-docked, the transducer face must be cleaned for shells and other marine growth.
Page 37 Apply anti-fouling paint as described in the dedicated procedure. Note Because some paint types may be aggressive to the polyurethane in the transducer, consult our list of approved paints. The list can also be found on Kongsberg Maritime (https://www.kongs- berg.com/maritime/). 451106/B...
Page 38: Painting The Transducer Face
Kongsberg EM 712 Maintenance Manual Painting the transducer face Marine growth (biological fouling) on the transducer face reduces the EM 712 performance. We recommend that you paint the transducer face immediately after installation, and then again as often as required to maintain the protection.
Page 39 Abrade the transducer surface using a sanding paper with 240 inch grit size. Do not exceed a surface roughness (R ) of 35 microns as this can influence the EM 712 performance. Remove all dust. Apply the primer, and let it dry.

Repeat the procedure until the tolerances are met Calibration During the sea trials, calibration surveys are required as described in the EM 712 end user documentation. In order to check and verify the performance of the EM 712 system, we strongly recommend that calibration surveys are done at regular intervals, or prior to any large survey.
Page 206: Vessel Coordinate System
Kongsberg EM 712 Maintenance Manual Note Calibration must be taken seriously. The final verification of correct installation can only be done during calibration at sea. Installation and operational parameters that do not meet the accuracy requirements may lead to incorrect data. To achieve the best results, the calibration must be planned and done carefully.
Page 207 Dimensional surveying and alignment In order to establish a system to measure the relative distance between sensors, a virtual coordinate system is established. This coordinate system uses three vectors; X, Y and Z. The X-axis is the longitudinal direction of the vessel, and in parallel with the deck.
