The present invention is a multi-functional dive tool designed for use by underwater or scuba divers, in particular divers that do so in rivers. The tool is a handheld metal spike designed to be utilized as a personal anchor or stabilizer when diving in water subject to strong currents. The tool has a pointed end to assist in pushing the spike into the river, ocean or lake bed. Unlike the prior art, the dive spike is constructed of materials with sufficient strength and weight that it can anchor the diver. The tool may also be used for a stand for cameras or lights, an anchor or pivot point for search lines, or an animal deterrent among other uses.

A spud greasing system includes a spudwell and a spud configured to slidingly engage with the spudwell between a deployed position and an undeployed position. The spud includes an access window configured to align and correspond with a window of the spudwell when the spud is in the undeployed position. A sheave assembly is mounted in the spud and includes a first sheave and a second sheave rotationally mounted proximate a front end and a back end of the housing, respectively. When the spud is in the undeployed position, a grease supply is configured to be selectively connected to a supply pipe through the window and access window of the spudwell and spud thereby supplying grease to the first sheave of the sheave assembly without removing the spud from the spudwell.

A drill device comprising: a pile configured such that same descends to a seafloor surface through a mooring installation device provided in a ship, and a part of the body thereof is fixed in an area of the seafloor surface as the upper surface thereof is pressurized in the vertical direction; a driving pipe configured such that same descends to the seafloor surface through a through-hole formed in the pile, the body thereof is inserted into a seafloor foundation, and same is recovered through the through-hole after excavation is completed; a chain, one end of which is fixed to one side of the pile, and the other end of which is introduced through the through-hole such that same is inserted into the seafloor foundation together with the driving pipe; and a drill bit unit.

A disconnectable mooring system for offshore semi-submersible floating structures. A disconnectable buoy has a number of mooring lines which include a buoy chain between the mooring chain and the buoy. The mooring chain and the buoy chain are connected via a three way mooring connector, with the third connection configured to pull the mooring connector to a mooring point on the structure. In a first configuration the buoy is disconnected and supports the mooring chains for recovery at shallow depths to be pulled in. In a second configuration, the mooring lines are pulled in via the mooring connectors thereby providing a spread mooring to the structure with the buoy chain left as a catenary between the buoy and mooring point.

A self-retrievable anchor with a shovel, lever, and manifold contains no welded parts eliminating weld failure due to tensional and bending forces during anchor retrieval. The anchor has interchangeable parts. The manifold attaches the shovel to lever, and contains at least an internal breakable fuse. A specific dimensioned fuse to anchor size is used. The fuse is not universal. When a tensional force is applied above fuse shear strength capacity, and below breaking strength of the rope, the fuse breaks rotating the shovel 180° about a pivot hinge pin. The anchor is released when stuck at sea bottom without any loss. The anchor's interchangeable parts makes it capable to change shovel shapes suitable to different sea bottom conditions. A stop bar on the shovel portion may be included. The lever may also detach during retrieval by a breakable pivot hinge pin or fuse pin alone, and shovel/manifold later replaced.

An anchor assembly for discerning if an anchor has securely engaged with the seabed, having a float with a length of line below no more than twice the distance from the water's surface to the seabed. The float includes a redirection element that allows the line to support a ballast weight via a descending portion of the line and an ascending portion that is secured to an anchor. The volume of the float and ballast weight are selected such that the float remains visibly buoyant when the anchor is stationary, yet becomes wholly or partially submerged when the anchor is in motion with respect to the seabed surface.
