In certain embodiments, a cap repair assembly includes first and second pile brackets for rigid mounting onto first and second piles of a pier: a cap beam for rigid mounting onto super-structure of the pier; first and second cap beam plates for rigid mounting onto the cap beam at different ends of the cap beam; first and second compression arms rotatably connected (i) at first ends to the first and second pile brackets and (ii) at second ends to the first and second cap beam plates. The cap repair assembly restores the load capacity of damaged or degraded piers. The cap repair assembly can further include one or more steel banding straps.

In certain embodiments, a pile bridge assembly includes first and second pile brackets for rigid mounting onto first and second piles of a pier; a cap bracket sub-assembly for rigid mounting onto a beam of the pier supported by the first and second piles; a first compression arm rotatably connected (i) at a first end to the first pile bracket and (ii) at a second end to the cap bracket sub-assembly; and a second compression arm rotatably connected (i) at a first end to the second pile bracket and (ii) at a second end to the cap bracket sub-assembly. The pile bridge assembly restores the load capacity of damaged or degraded piers. The cap bracket sub-assembly can include first and second cap brackets, and the pile bridge assembly can further include one or more tension-managing straps.

Integrated probes and probe systems suitable for attachment to a robotic arm of a remotely operated vehicle are disclosed. The probes and probe systems serve to perform cleaning operations and both cathodic protection (CP) voltage measurements and ultrasonic testing (UT) thickness measurements at an underwater surface. The cathodic protection measurement system includes one or more electrically conductive legs that extend outwardly from the probe. These legs are arranged about a cleaning tool and an ultrasonic sensor. When the integrated probe contacts the underwater surface, at least one leg contacts the surface, thereby providing a desired distance between the probe and the underwater surface for efficient cleaning and UT inspection. The underwater surface can be cleaned and CP and UT measurements can all be performed using a single, integrated probed during a single operation, without having to reposition the probe.

A base supporting an offshore wind power generator includes a fender portion composed of a pair of cylindrically shaped first fender portion and second fender portion for cushioning an impact when a ship touches the fender portion, and rung portions extending horizontally from the fender portion toward the base and composed of first rung portions and second rung portions installed at predetermined intervals in the vertical direction. A worker on board the ship can safely transfer to the adjacent rung portions when the hull of the ship kept touching the fender portion.

An offshore wind turbine erected in a body of water including a generator, a base, a nacelle, a tower having a first end mounted to the base and a second end supporting the nacelle, an electrolytic unit electrically powered by the generator to produce hydrogen from an input fluid, in particular water, and a fluid supply assembly for supplying the input fluid from a fluid inlet arranged below a water level to the electrolytic unit arranged above the water level, wherein the fluid supply assembly includes a pump and a fluid connection between the fluid inlet and the electrolytic unit.

An offshore well-processing system includes a mobile offshore drilling unit and a remote well-processing device configured to be positioned on an offshore platform different from the mobile offshore drilling unit, the mobile offshore drilling unit defining at least one well center and comprising at least one primary drill rig including at least one drill floor and at least one hoisting system for raising and lowering tubular equipment through the at least one well center from/into a well in the seafloor. The mobile offshore drilling unit and the remote well-processing device are configured to be operationally coupled to each other; and the mobile offshore drilling unit is configured to assist in performing concurrent well-processing tasks on respective wells, including the first well processing task performed by the remote well-processing device on a first well and a second well-processing task concurrently performed by the offshore well-processing system on a second well.

A container for maintenance capsule as a component of a maintenance system for an offshore wind turbine maintenance program. The container transports tools, parts and maintenance personnel to and from respective wind turbine towers. The container is seaworthy, watertight and floatable, and can be loaded on a maintenance vessel which carries the container to and from a wind turbine tower.

A cleaning device that passively self-adjusts to improve biofoul removal across curved, non-uniform, or irregular underwater surfaces. The cleaning device includes a motor, one or more shafts coupled to the motor and coupled to one another via at least one universal joint, and a cleaning mechanism for removing biofoul from the target surface. The cleaning device includes an alignment mechanism that restricts the cleaning mechanism's movement to improve biofoul removal. The alignment mechanism can include bearings, spring components, dampening material, adhesion components, floatation objects, or a combination thereof.
