PIPE-LAY BARGE MOORING ORIENTATION PREDICTED.

Third installment in series devoted to ″Marine Pipe-lay and Recovery″ postulates that the optimum orientation for combined effects of waves, winds, and currents from any direction can be easily simulated with computer procedures. Results should help downtime due to weather conditions during actual pipe-laying. It may be necessary to lay pipe along a narrowly prescribed path that has been preswept to eliminate ridges and subsea sand dunes. But procedures described would allow the contractor accurately to simulate procedures for specific conditions and to stay within the prescribed route. Three sample cases are investigated.
