A method of installing one or more anchors in an underwater substrate in a body of water including installing an anchor into the underwater substrate by rotating an anchor installation vehicle about a central axis Y to drive the anchor coupled to the anchor installation vehicle into the underwater substrate. The anchor installation vehicle includes a vehicle frame having a top end and bottom end, a plurality of arms extending outward from the vehicle frame, one or more rotational thrusters disposed at distal ends of the respective arms, and an anchor system that holds the anchor extending from the bottom end of the vehicle frame with the anchor aligned with a central axis Y.

An anchor installation vehicle that includes a vehicle frame having a top end and bottom end, one or more rotational thrusters, and an anchor system configured to hold an anchor extending from the bottom end of the vehicle frame.

A marker buoy constructed of a main shaft extending vertically when in use and including a marker flag, a floating body, and a spool mounted to the main shaft.

A signal buoy (1) for retrieval of submerged objects, the signal buoy line's cross section has an aspect ratio greater than two and two tenths to one and preferably greater than four to one. In some aspect the signal buoy line includes conductors so as to permit communicating with submerged objects. In other aspects, the present disclosure teaches a combination of a signal buoy and a buoyant fiber mooring rope storage structure for storing submerged in a body of water and above a seabed or other bottom of the body of water a fiber mooring rope for future retrieval.

An off-shore wind turbine system is assembled using a platform or jack-up vessel, and a first base anchored to the seafloor at a blade assembly off-shore location. A buoyant tower is attached to the first base. A crane provided on the platform or jack-up vessel is used to lift blades and blades, which are then coupled to a turbine held in a nacelle provided at the top of the buoyant tower. The buoyant tower, the nacelle, and the blades are detached from the first base. The buoyant tower, the nacelle, and the blades are towed to a wind farm and connected to a second base provided in the wind farm. The buoyant tower, the nacelle, and the blades are further stabilized using mooring lines spanning between the buoyant towers and other bases provided in the wind farm. The first base and/or the second base include anti-rotation features.

To make secondary anchoring of small boats quick, safe, versatile, a low cost buoyant apparatus with an attached tripping strap has been invented to permit transport of a secondary anchor to its holding location. The invention, in addition serves to prevent excessive boat swings once anchored in restricted anchorage, and can also serve as a marker in the event that an earlier anchored boat needs to move and return to the same spot. This buoyant apparatus is very versatile; it can be used from the boat's bow, from the stern, and also as a lunch hook. Although the buoyant ring has an appearance of a life preserver, it is not intended for that use, and does not qualify as U.S. Coast Guard or Sheriff Regulation safety equipment.
