An active rigging system, using multiple lines to support a load, places a constant tension on at least one of the lines. The constant tension allows a resistance to slack in the line, which in turn allows the line to maintain support of the lines' respective share of the load. This configuration allows a reduction of stress in the load and an enablement of support of loads having an unequal weight distribution. Additionally, the invention includes a method for relieving stress from a load, supported by multiple lines generally susceptible to slack. The method includes placing a constant tension on at least one of the lines to allow that line to resist slack. The resistance to slack involves utilizing a tension force and an adjustment of the line via a pulley.

Active rigging device

An apparatus and method is provided for transporting, installing, retrieving, and replacing a sensor array of individual sensor pods at a geographically remote location, such as on the sea floor. The apparatus consists of a remotely operated vehicle (ROV), a carousel attached to the ROV, a pod ejector mechanism attached to the carousel, and a manipulator with a manipulator end effector attached to the ROV. The carousel contains a plurality of sensor pod holders, where each sensor pod holder is capable of holding a sensor pod. The pod ejector mechanism is capable of discharging a fresh sensor pod, while the manipulator end effector is capable of lifting a depleted sensor pod and placing the depleted sensor pod in an empty sensor pod holder in the carousel.

Method and apparatus for installing a sensor array

A cable deployment system and method for laying a cable on the sea floor. The cable deployment system includes a cable having a first cable section connected to a riser cable section. The riser cable section includes an armor that is connected to a drum capable of containing a required length of the first cable section. A stinger is attached to the drum and shaped to allow the first cable section to exit the drum. The cable deployment system also includes a tensioning device attached to the drum. The tensioning device is capable of maintaining a tension in the first cable section during deployment of the first cable section from the drum. The method of deploying the cable in deep water from a surface vessel includes the steps of containing the first cable section within the drum and lowering the drum from the surface vessel. An end of the first cable section is secured to the sea floor and the first cable section is deployed from the drum onto the sea floor.
