A floating platform for supporting generators of power derived from the wind, the waves and ocean currents, adopting an approximately disc-shaped general configuration with a circular or polygonal perimeter, which optimises its size and therefore minimises substantially its weight and likewise its production costs, as well as other associated complexities; which eliminates the possibility of entering into resonance with the movement of the ocean waves and thus not damaging the equipment installed, not overturning, and not surpassing the maximum list acceptable for wind power generators, nor wave power generators, nor ocean current generators; and which withstands the waves of the greatest size possible, all due to a ratio between its depth or height (13) and the diameter (14) thereof of between 0.06 and 0.35.

A system and method for performing structural health monitoring on a structural element while it remains in service and experiences normal loading. The energy input to the element will be the normal and random energy inputs the element sees in service. The inventive system places an intelligent module at one or more points along the length of the structural element. The inventive system collects mass data from multiple modules on multiple elements. The system then applies machine learning or artificial intelligence techniques to detect changes in the measurements received from one or more modules. This approach reduces or eliminates the need to provide calibrated input energy. The invention preferably provides the ability to determine the condition of one element or sub-element under measurement relative to other elements.

Methods and apparatus for monitoring windlass rotation are provided to determine the real time rate and length of rode release when anchoring a boat. The rotation can be monitored in real time using directional sound and/or electromagnetic radiation receivers and/or transmitter in a module attached to the windlass. Another windlass module can monitor windlass rotation using micro-electromechanical systems (MEMS) components such as accelerometers, magnetometers, gyroscopes, and/or inertial measurement units (IMU) to sense motion and/or position.

A clamp comprises a plurality of pads; a belt for clamping the pads that is maneuverable between an unclamped configuration and a configuration clamping the pads against the production line; a clamping actuator for the clamp, mounted on a first point of the clamp, the clamping actuator having a grasping member for a second point of the clamp, the grasping member being movable between a deployed position and a retracted position moving the second point towards the first point. The spacing-apart mechanism is able to move the grasping member between a spaced-apart configuration of the second point in the deployed position of the grasping member and a grasping configuration in an intermediate position between the deployed position and the retracted position.

A swivel (100) for a mooring line comprises a first element (110) with a first line coupler (111) and a second element (112) with a second line coupler (113). The first element (110) and the second element (112) are rotatable relative to each other. An electric power generator (120) converts a relative rotation between the first element (110) and the second element (112) into electric power. In use, the line couplers (111, 113) are attached to separate segments of the mooring line. A pull F applied to or relieved from the mooring line causes the relative rotation. The swivel preferably contains a battery and a control unit, and may supply power to one or mode sensors, transmitters and/or transducers (130) built into or external to the swivel (100). A system for monitoring a mooring arrangement is also disclosed.

A connector or connector assembly (10, 210), such as a subsea or underwater connector or assembly including a first member (18, 218) movably connected or connectable to a second member (36, 236) and a first inductive element (24, 224a) provided on the first member (18, 218), the first inductive element (24, 224a) being arranged for inductive transmission and/or reception with a second inductive element (42, 242a) of the second member (36, 236). The first member (18, 218) may rotatably or pivotably connected or connectable to the second member (36, 236). The first inductive element (24, 224a) may be arranged on the first member (18, 218) to maintain inductive transmission with the second inductive element (42, 242a) of the second member (36, 236) throughout movement of the first member (18, 218) relative to a second member (36, 236).

A method is presented for simulating marine assets (MA) in an offshore operation. The marine assets comprise at least an anchor, a line coupling the anchor with a winch, and a support platform located offshore for supporting the winch. The method involves a computation stage for estimating a state of the marine assets using a computational model and received sensor data (Ds) pertaining to a state of the marine assets and/or of an environment (ME) wherein the marine assets are used. The computational model of the marine assets (MA) includes at least a specification of an anchor, a specification of a winch and a specification of a line coupling the anchor with the winch. The at least a line is modeled as a first portion extending between the winch and a touch-down point where the line touches the seabed and a second portion extending between the touch-down point and the anchor. Additionally a simulation system is presented for simulating the marine asset, and an arrangement including the marine asset and the simulation system.

Novel techniques and equipment for anchoring a boat include sensing and measuring the real time rate and length of rode release based on detecting real time changes in the angular position of a windlass by computer vision using a portable computing device. Rode release is also detected using novel methods based on sensing sound, rode chain movement, and sensing acceleration and/or motion. The apparatus can include software operable to provide safe anchoring based on monitoring real times values of the rate and length of rode release, comparing these values to the speed and position of the boat, and providing local and remote status and alarm information to crew members.

Systems and methods for tensioning mooring lines are provided. The systems include an in-line tensioner that may include a removable chainwheel, a tail chain disconnecting table configured for disconnection of a tail chain and docking of an ROV, a chain guide having low-friction pads that reduce frictional engagement between the in-line tensioner and mooring chains, and a target link stopper that is configured to stop movement of the mooring line at a predetermined location, such that the mooring line has a predetermined length and such that a predetermined link of the mooring line is positioned within a gripping zone of latches of the in-line tensioner.

The disclosed method measures a line angle of a mooring line connected to a floating object floating in a body of water, the mooring line being connected between the floating object and an anchoring body disposed in a bed of the body of water, in which the floating object is coupled to the mooring line by a line connector. The method includes: defining at least three data points each associated with a respective location on the mooring line; on the data points obtaining a value associated with the location on the mooring line; determining parameters of an equation describing an anchor line curve from the values associated with the location on the mooring line for the data points; calculating at a predetermined position on the mooring line a line angle of the mooring line from a derivative of the equation at the predetermined position based on the parameters.
