Abstract: Provided herein is a system and method for installing subsea insulation on flowlines, connectors and other subsea equipment by a remotely operated vehicle. This system provides a mold designed and built to suit the parameters of the subsea item to be insulated. The mold is installed around the subsea item to be insulated and then injected with a liquid solution of insulation material. The liquid solution is then allowed to solidify, forming a gel molded insulation.

Abstract: A subsea well intervention system that permits dynamic disconnection from subsea well intervention equipment without removing any of the equipment during a drive-off condition is provided. The system includes a blowout preventer module operatively connected to a subsea tree, a lubricator assembly attached to the blowout preventer module that provides access to the interior of the blowout preventer and the subsea tree by well intervention equipment, and an umbilical module including a fail-safe disconnect assembly. The fail-safe disconnect assembly is disconnected using hydraulic power provided by the control umbilical or by a remotely operated vehicle.

Abstract: A method and apparatus for heating a portion of a subsea structure is provided. The method includes pumping a fluid through a length of tubing such that the temperature of the fluid increases. The temperature increase of the fluid is created by friction in the tubing, and may be also be created by at least one pressure reducing device such as an orifice, pressure reducing valve, or relief valve. A subsea structure may be heated by transferring heat from fluid circulating in a closed loop configuration or by direct application of fluid to the subsea structure using a nozzle. A remotely operated vehicle may be utilized to transport some or all of the equipment necessary, including pumps, tubing, heat exchangers, nozzles and tanks. The remotely operated vehicle provides power to the pumps used for circulating fluid through the tubing.

Abstract: 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.
