Once clean, a small bead of silicon grease (like Molykote 44) should be placed on the flat mating
surfaces prior to mating. Products like WD-40 or a compound grease product are not recommended.

A 15 m interface cable is provided for the MBES. If the MBES is, for example, set up on an ROV, a
whip may be used to interface the MBES through the ROV tether to the topside SIR box. The pin
outs of the 8conductor SubConn connector are shown in APPENDIX B and the interface of the SIR
unit with associated sensors is detailed in APPENDIX C.

The MBES unit forward / aft line should be mounted and orientated as parallel as possible to the
vessels fore aft line, as indicated in Figure 3-1 Orientation of the DT101Xi and Figure 3-2 Orientation
of the DT102Xi ([mm] and inches):

For a pole mount mobilization, the cable going into the MBES should be secured in such a way that
the water pressure during vessel transit does not act on the cable and stress the connection. It is
essential that the MBES be orientated such that the connector is facing astern to offer protection
from such stress, as well as to ensure the MBES functions correctly. The pole should be braced to
prevent movement or excessive vibration.
