Disclosed is an assembly for anchoring a submerged vehicle to a stationary object. The assembly includes a telescoping tube having a hollow inner tube and a hollow outer tube, each the inner tube and the outer tube having a proximal end and a distal end. The distal end of the inner tube slidably received within the outer tube through its proximal end. A snap button configured at the proximal end of the outer tube that can engage with a hole near the distal end of the inner tube for locking the movement of the inner tube within the outer tube. A rope having a first end and a second end, the first end of the rope attached to the inner tube near its proximal end. The second member passes through the eye of the spring hook and into the proximal end of the inner tube to form an anchoring loop. The second end of the rope exits the telescoping tube through the distal end of the outer tube and forms a boat hook loop.

The present invention includes systems and methods for a continuous-wave (CW) radar system for detecting, geolocating, identifying, discriminating between, and mapping ferrous and non-ferrous metals in brackish and saltwater environments. The CW radar system generates multiple extremely low frequency (ELF) electromagnetic waves simultaneously and uses said waves to detect, locate, and classify objects of interest. These objects include all types of ferrous and non-ferrous metals, as well as changing material boundary layers (e.g., soil to water, sand to mud, rock to organic materials, water to air, etc.). The CW radar system is operable to detect objects of interest in near real time.

A system and method for a line shock absorbing and/or tensioning device formed from a metal rod having a central coiled portion acting as a torsion spring with two arms extending radially from the coiled portion whereby the ends are terminated with a pigtail to allow a line to be captively held inside without the need to thread the line ends through. The line, when slackened, is manipulated inside the two pigtails and routed through a third formed pocket in the centered coiled portion to form a non-linear path. As the line is stressed, the line wants to straighten, therefore causing the V-shaped arms to flex apart and absorb the resulting shock while providing elasticity and elongation to the line itself.

A release system for a tether line includes a housing having a side that is at least partially open. A tether lead within the housing is adjacent to the side of the housing. A release mechanism in the housing includes a shackle having a closed end and an open end. The shackle is disposed in the housing at a portion therein that is lower than that of the tether lead. The release mechanism also includes a hinge for mounting the shackle within the housing. In a tether-retention mode, the open end of the shackle faces the top of the housing and the shackle is prevented from rotation about the hinge. In a tether-release mode, the shackle is free to rotate about the hinge under gravity wherein the open end of the shackle rotates to face the side of the housing.

A chain brace for restricting relative movement between first, second, and third serially connected links of a chain. The chain brace can include a wedge block defining a bore at least partially therethrough, first and second outer blocks, a capture frame that can include a reaction plate that can define a bore therethrough, and a tension member. The capture frame can be configured to position the outer blocks and the wedge block within the second link of the chain. The tension member can be positioned through the bore defined by the reaction plate and into the bore defined by the wedge block to apply a force on the wedge block such that the wedge block displaces the first and second outer blocks into contact with the ends of the first and third links of chain, respectively, to restrict relative movement between the first, second, and third links of the chain.

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 bade 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.

Disclosed is a mooring system (1) for mooring a floating vessel. The mooring system includes a connector structure (10) for attachment to a mooring line and an anchor structure (20) to be anchored to a sea bed. The connector structure comprises an engagement portion (14) and an attachment portion (12). The anchor structure comprises an open guide channel (22) extending from an entrance region (24) to a terminal region (26); and sized to accommodate at least the engagement portion of the connector structure. A longitudinal opening to the guide channel provides access for a mooring line connected to the attachment portion, while the connector and anchor structures are connected and disconnected. Connection and disconnection can be controlled from the water surface.

A floating body to which an aquatic or marine facility is installed or which is connected to a lower part of the aquatic or marine facility to hold the aquatic or marine facility on water or the sea is proposed. The floating body may include a main floating body which floats on water or the sea by using buoyancy, and a magnet provided on a first vertical side of the main floating body. The floating body may also include a coupling member provided on an opposite vertical side of the main floating body by corresponding to a magnet of another floating body such that the coupling member is coupled thereto, and a mooring line installed on a part of the main floating body to moor and hold the main floating body on water or the sea.
