The present disclosure relates to a method and device for tapping into a vessel, typically to recover fuel or cargo oil from sunken ships but may be applicable to other situations involving transfer of fluids from places that are inhospitable to humans. A remotely operable hot tap installation tool has a releasable securing and stabilising arrangement; a hot tap assembly holder; at least one first drive mechanism configured to apply torque to studs at a plurality of attachment stud locations to securely fasten the hot tap assembly to the vessel; a second drive mechanism configured to apply torque to a hole-drilling assembly to cut a hole into the fluid vessel wall; and an indexing mechanism configured to move the first drive mechanism between multiple attachment stud locations.

The present invention generally relates to containment and control of an oil spill caused by a damaged or broken riser in deep water. More specifically, the present invention relates to a reusable unit that will contain oil spills to a specific location and will also allow oil to be harvested as it flows to the top of the unit while minimizing or even eliminating any environmental clean-up impact or cost. The unit of the present invention is dropped over a damaged or broken riser in a closed position, the unit is released and stabilized in sections until the surface is reached and the containment unit is completely erected.

An access device is provided for access to a fluid tank, especially a fluid tank of a ship. The access device includes a drill, a thread-forming unit, a hollow body with an external thread and a connection plate. The hollow body is provided with a valve.

A drilling system configured to install a tap assembly into a ship skin is disclosed. The drilling system comprises a remotely-operated underwater vehicle and a drilling assembly configured to be operated by the remotely-operated underwater vehicle. The drilling assembly comprises a frame comprising an attachment element configured to hold the drilling assembly to a surface of the ship skin. The drilling assembly further comprises a drill actuation system comprising a linear actuator attached to the frame and a rotary actuator, wherein an actuation of the linear actuator is configured to move the rotary actuator relative to the frame to install the tap assembly into the ship skin by driving the tap assembly with the rotary actuator and the linear actuator.
