A vessel and a method for installation of a pile adapted to support an offshore wind turbine are described. The method includes a) suspending the pile from a hoisting cable in a substantially vertical orientation; b) providing a lower end of the pile in a pile holding system limiting horizontal motion of a pile portion held by the pile holding system; and c) lowering the pile with the pile being held by the pile holding system. The lowering includes at least lowering the pile through a splash zone of a body of water, and during step c), two tugger lines are directly or indirectly connected to the pile at a location between the pile holding system and the hoisting cable, said tugger lines being operated to damp motion of the pile in two respective horizontal directions.

A marine or land habitation system includes a habitable chamber and a monopole column supporting the habitable chamber at a first end of the monopole column. The monopole column includes a second end, opposite the first end, for mounting in the seabed or dry land. The habitable chamber is moveable with respect to the column both rotationally and vertically.

The invention relates to a method for the installation of a marine (or in general, aquatic) wind-powered generator tower, wherein said tower advantageously comprises a foundation that is open at the top and equipped with a substantially flat lower slab and a perimeter wall. The method includes, in the different stages thereof, the depositing or removal of ballast material in or from the main cavity of the foundation, and wherein in the absence of said ballast material, the wind-powered generator or the foundation is a floating or self-floating structure. The method is particularly suitable for the installation of wind-powered generators in areas of low depth (or near-shore areas), preferably of less than 15 m.

A system is disclosed including but not limited to a a jack up processor in data communication with each for dynamically balancing loads in real time on a plurality of legs supporting a jack up rig platform having a plurality of gear box motors on the plurality of legs. A processor reads data from sensors on gear box motors on the legs and selects a stored torque profile from a computer readable medium based on the load data from the sensors; and sends the torque profile to the plurality of gearboxes. A computer readable medium and neural network are disclosed for dynamically balancing loads on the plurality of legs in real time.

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.
