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.

The present invention includes systems and methods for a continuous-wave (CW) radar system for detecting, geolocating, identifying, discriminating between, and mapping ferrous and nonferrous 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 nonferrous 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.

Disclosed is a LADCP and USBL combined observation device and a use method thereof. The device includes a cable winch system, a mounting frame, a LADCP system, a USBL beacon and a correction system. The LADCP system, the USBL beacon and the correction system can be mounted to the mounting frame by adopting a hardware support platform. The cable winch system can drive the LADCP system to deploy or recover along a vertical section. The LADCP system is used to obtain the current velocity of a single small profile, and the USBL beacon can locate the underwater position information, and the correction system can obtain data information in the seawater where the mounting frame is located, so as to calculate an absolute current velocity according to the velocity obtained by the LADCP system and the current data obtained by the correction system.

Yoke mooring systems and processes for using same. The system can include a turntable connected to and rotatable with respect to a base. A yoke can be connected to the turntable such that the yoke can at least partially rotate about a longitudinal axis of the yoke and at least partially rotate about a second axis that can be orthogonal to the longitudinal axis. A first and second link arm can be connected to the yoke and to a first component of a first and a second releasable connector, respectively. A first and second lifting line can be connected to the second end of the first and second link arms, respectively. A first and second lifting device can be disposed on a vessel and configured to be connected to a second end of the first and second lifting lines, respectively, to lift and lower the link arms and the yoke.

A chain damping and shock absorber system for a chain includes one or more damping devices, each damping device installed to a segment of the chain, such that the chain and the one or more damping devices installed to a chain segment form a damped and compressed chain assembly. In response to a tensile force applied to the chain, the chain segment is extendable to an extended length which is between its compressed length and its full length. Methods of installing the chain damping and shock absorber system are provided.
