Claim:
1. A method for determining start and stop times of at least one selected pipe laying operation from a plurality of different pipe laying operations on a pipe deployment vessel, comprising: measuring tension on a pipe deployed from a reel on the vessel; measuring velocity of pipe motion with respect to the vessel; measuring rotational velocity of the reel; measuring geodetic position of the vessel with respect to time; automatically determining the start and stop times of the at least one selected pipe laying operation from the measured tension, motion velocity, rotational velocity and geodetic position when the measured tension, motion velocity rotational velocity and geodetic position meet selected measurement conditions; recording the start and stop times of the at least one selected operation to enable determination of procedures for optimizing vessel operations and performing pipe laying operations from the vessel using the optimized vessel operations procedures.
