CHAPTER 4: E
This chapter provides instructions for equipment maintenance and includes guides
for taking care of the equipment on a daily, weekly, and long term basis.
4.1
Maintenance General Comments
Equipment used at sea is subjected to severe environmental and handling
conditions. While the Series 3900 Sonar System is designed to operate in such
conditions, a certain amount of routine maintenance is necessary to ensure trouble
free, long term operation.
Keep a maintenance log. This provides assistance in tracking what has or has not
been done with the system. A log is useful when tracking problems, if they do
occur, and is especially important if more than one SP-II TPU, laptop computer or
towfish is used in a large survey operation. Inventory the system, related spares
and accessories carefully. Record the serial numbers of the major components,
such as the SP-II TPU, the laptop computer, and the towfish. Store the shipping
boxes in a safe place so they can be reused when needed. A small amount of
regular maintenance and care makes the critical difference in a successful field
operation. The following pages contain the recommended routine checking and
maintenance schedules for a daily, weekly, and long term basis.
4.2
Maintenance Checklists
4.2.1
Perform the following maintenance steps at the end of each day's operation:
Turn off the power to the SP-II TPU and to the laptop computer.
1.
2. Verify that all cables and connectors are secure and tightened.
3. If fresh water is available, wash down the towfish and towing apparatus. Cover
them while not in use to protect against salt water spray and to minimize
corrosion.
