An apparatus may include a center section of a tower. The apparatus may further include at least a first support and a second support each comprising a telescoping assembly, wherein the telescoping assembly may include two or more members longitudinally moveable relative to one another for moving the center section of the tower between at least a first position and a second position.

A watercraft with improved safety and stability is provided. The watercraft includes a shell defining a plurality of raceways for receiving water during certain maneuvers of the watercraft, thereby excerpting force upon the watercraft in a first direction. The shell is configured so as to prevent or otherwise inhibit the water from excerpting an opposed second force upon the watercraft. An intermediate panel of the shell provides increased flexibility, thereby serving as a shock absorber for the watercraft.

Boat configurations and implementations are provided to make it more accessible for disabled people to participate in boating, commercial or recreational. A boat engine may be positioned in front of the helm, a flat boat deck may allow access to the engine and helm by a person in a wheelchair or similar physical impairment, and a flat access to the boat deck at the stern of the boat may allow disabled people to easily get on board.

A system for controlling aeraulic conditions existing above an aerial arrival zone includes anemometric components and aeraulic components. The anemometric components deliver speed and bearing angle values that characterize a relative wind speed with respect to the aerial arrival zone and to a superstructure located close to the aerial arrival zone. The aeraulic components are capable of modifying air movements above the aerial arrival zone, and are controlled according to the wind speed and bearing angle values. Such a system is particularly suitable for use on board a ship able to carry a helicopter, in particular on its afterdeck.

This relates to vessels in general, but in particular to displacement vessels designed to be exposed from low to medium to high waves. Both for comfort of persons, animals or fragile goods, steady sailing is preferred, without causing the waves slamming in on the vessel hull or excessive pitching of the vessel. This is also the case for service and supply vessels performing operations in relation to offshore or subsea installations. To obtain a solution to the aforementioned issues the present invention provides a vessel, wherein a stern of the vessel extend below a design waterline (Tdwl), and wherein opposite side surfaces of the stern, when seen in an opposite direction of the vessels primary sailing direction, form an acute angle under and above the design waterline (Tdwl) to decrease the vessels displacement in the rear end and are adjoined along at a line of symmetry forming a stern centerline.

The invention has for object a system and a method for the realization of floating platforms formed by the aggregation of floating forms in reinforced concrete, the union set of the modules is made integral forming a single plate inserting and pulling special steel cables that cross the entire platform in sheaths arranged in the walls of the modules themselves, the pulled cables, locked in this position, compress the plate to increase resistance, the present method and system are also characterized by the fact that the quota of the platform does not vary with the tides and the loads to which it is subjected.

Disclosed is a measurement system for aquatic environments, including a surface vessel and a submersible device, the submersible device including a hull, propulsion, guide, and sensors for taking measurements. The submersible device can either be launched from the vessel in order to then maneuver underwater independently of the vessel during a remote deployment phase, or be stored in a vessel during a non-deployment phase, the vessel including at least one hull and propulsion and guide, the at least one hull of the vessel including a submerged portion located below a waterline. The submerged portion of the at least one hull of the vessel includes a recess designed to receive at least an upper portion of the hull of the submersible device when the latter is stored in the vessel, the recess being arranged entirely below the waterline so that the submersible device remains completely submerged during storage.

This invention is directed to a column floater with extended cylinder and a ring buoy-group, which comprises an upright buoy at a water surface, an extended cylinder, a positioning system and a topsides. The top of the upright buoy is above the water surface and a moonpool is either set or not in the center of the upright buoy through the top to the bottom. The extended cylinder, connecting to the bottom of the upright buoy and extending downwards, includes two types of fixed and sliding to form a column floater with fixed extended cylinder and a column floater with sliding extended cylinder respectively. The positioning system is one or two combined of mooring system and DP system. The column floater with extended cylinder is a new type floating platform with multi-purpose, combining advantages of the spar platform and the current cylindrical FPSO, high performance, safety and reliability.
