Patent number: 9919771Abstract: A system and method for guiding a dropped suspended load includes a safety winch, safety buoy, and safety anchor spaced relative to one another and an offshore rig's lifting system so that the dropped load falls away from certain seabed locations and to a safe landing area. A safety winch cable runs from the safety winch to the safety buoy, and from the safety buoy to a connection to the load. The load, when in a run-away state, falls away from vertical and toward a predetermined safe landing spot on the seabed floor. The safety buoy is then used to locate the load.Type: GrantFiled: November 18, 2015Date of Patent: March 20, 2018Assignee: Cameron International CorporationInventors: Johnnie Kotrla, James Hogan, Ross Stevenson, Jesse Garcia
