Abstract: A suction anchor for a remotely operated vehicle comprising a frame attachable to a remotely operated vehicle, anchor cans beneath the frame beneath and connectable to a pump. In particular the anchor can be deployed as part of a method for sampling or measuring the seabed comprising the steps of attaching a frame to the remotely operated vehicle, the frame having one or more downwardly mounted anchor cans and a mast to which sampling and/or measuring equipment is attached, placing the anchor cans on an underwater floor, and, at least in partially, evacuating the cans of water embedding them in part into the underwater floor, sampling and/or measuring the underwater floor using the sampling and/or measuring equipment. It can be used to mount other sensor equipment requiring a stable platform.

Abstract: Novel subsea excavation apparatus and methods that exert force between a subsea anchor point and an excavator using a subsea actuator. In some examples the subsea actuator is attached to an anchor point on the seabed and the excavator directly. In other examples, a guide frame is anchored to the seabed to provide anchor points fixed relative to the seabed and the subsea actuators are attached to the guide frame and the excavator. In further examples, the subsea actuators can be attached to the excavator through a carrier frame or other excavator guides rather than directly to the excavator.

Abstract: A system for deploying an undersea anchor is provided, where the system includes a controller programmed and configured to monitor the drilling and grouting of micropiles in real-time and compare the metrics detected by such monitoring against pre-determined design criteria to substantially ensure micropile deployment meets the design criteria upon completion of the drilling and grouting process during micropile deployment. The system may also include means for pre-tensioning the micropiles after deployment, where the controller is programmed and configured to determine whether the pre-tensioning process conforms to design criteria.

Abstract: A method and a device for subsea wire line drilling permit the recovery of a full core barrel with a coiled tubing, without pulling up a drill string.

Abstract: A subsea drilling system includes a drilling module having a tool carousel being removable and replaceable in or out of water, a skid module and an ROV to be connected to and disconnected from the skid module in or out of water, for operating the subsea drilling system with the ROV. A method for operating a subsea drilling system includes removing a tool carousel from a drilling module and replacing the tool carousel with another tool carousel, in or out of water. An ROV is connected to a skid module and disconnected from the skid module in or out of water. The subsea drilling system is operated with the ROV.
