A device and method for sampling underwater parameters is provided. The device is configured to be removably secured to, and navigated along a length of, an underwater cable during an underwater cable recovery operation. The device may include one or more sampling elements configured to sample underwater parameters while the device moves along the length of the underwater cable. The device may include a computing unit in communication with the one or more sampling elements which is configured to receive output data of the one or more sampling elements and record the output data for subsequent analysis.

An apparatus including a robotic manipulator coupled to an oilfield device to facilitate support operations. The robotic manipulator can include a tool for interacting with components of the oilfield device, and the robotic manipulator can provide three translational degrees of freedom of the tool with respect to the oilfield device. Additional systems, devices, and methods are also disclosed.

A dredge head assembly is disclosed. The assembly includes: a shroud having a generally open bottom end and a top end; a screen structure covering the generally open bottom end of the shroud; a suction pipe with a first end connected to the top end of the shroud and a second end configured to be operatively connected with a pump which induces suction; a handle connected to and extending from the shroud and having at least one grasping portion; and one or more vacuum relief valve assemblies, each comprising a valve, at least one opening configured to be in communication with water, and an actuation mechanism positioned to be accessible to a diver. Dredging systems and methods of dredging are also disclosed.
