7.1 Introduction
Before retrieving the equipment, ensure
is read and fully understood.
7.2 Retrieval Planning
It is advised that a retrieval procedure is formulated and understood by all involved before attempting
to retrieve any equipment.
Note
Retrieval using ROV manipulators or grappling with boat hooks can result in major damage to the
transducer.
A dedicated loop of rope fitted to the transducer guard shackle or floatation will reduce the risk of
damage to the equipment during recovery.
For ROV handling, add a metal ring to this rope loop. The rope loop must sufficiently long enough to
allow the ring to fall below the acoustic transducer.
Note
The floatation bump-stop ring must not be used to lift more than the transponder and float collar.
A transponder floating to the surface can be tracked during its ascent by ranging to it, or by making
repeated depth readings.
7.3 Retrieval from the Water
When a transponder reaches the surface, it will float approximately horizontal, depending on the float
collar fitted.
Note
The transducer guard must not be used to hook the transponder, this will result in damage to the
transducer.
A boat hook can be used to hook:
l
A rope loop attached to the transducer Guard Shackle
l
A rope loop attached to the floatation bump stop
l
A lifting point fitted to the floatation collar
l
The release guard if fitted
The transducer guard must not be used to hook the transponder, this can result in damage to the
transducer.
If recovered into a small boat, the transponder should be lifted on board the mother vessel using a
crane attached to the lifting shackle or the lifting point on the float.
7.4 After Retrieval
