buoy systems are covered.
Procedures set forth may be modified to suit local
environmental conditions and/or material constraints, or to accommodate a special
mooring design. The procedures developed herein assume that the tasks will be
accomplished using a floating crane or crane barge for installation and recovery.
2.1.2 PLANNING AND PREPARATION. Development of a plan is a necessary
r e q u i r e m e n t prior to commencing operations. The plan should include the
equipment needed and the procedures necessary for accomplishment of the task.
Design drawings, as well as materials required, should also be included. Recovery
plans should take into account the as-built drawings. The plan should be prepared
well enough in advance to allow riggers, crane and barge operators, design
