摘要： Modular structure for protecting an offshore vessel in a body of water from forces of ice features in the body of water is described. The modular protective structure comprising a protective harbor wall constructed and arranged to enclose a harbor space and to counteract the forces of ice features in the body of water. The modular protective structure also comprising a flotation support supporting the protective harbor wall. The flotation support having a capacity to position the modular protective structure at a raised position where the flotation support maintains at least a portion of the protective harbor wall above the water surface such that a harbor is established and the offshore vessel is protected from the forces of ice features in the body of water. Methods which utilize such a modular protective harbor structure are also described.

摘要： Ships for navigating in icy waters are provided. Such ships include in the stern area a wedge which extends from bottom of the ship downwards transversely to the ship. The wedge may have a first surface inclined towards the bow and a second surface inclined towards stern with respect to a horizontal plane. These two surfaces can be connected to each other forming a lower edge of wedge. The wedge is at least partially arranged below waterline of the ship. The first inclined surface is dimensioned in such a way that in the case of forward motion, the first surface contacting the flow of water, generates a lift force in order to modify the longitudinal trim of the ship acting as a trim wedge. The second inclined surface also is shaped advantageously in the case of reverse motion in icy waters.

摘要： A marine seismic surveying apparatus for obstructed waters includes a deployed device and a buoy. The deployed device is disposed at an end of a streamer and is towed below a surface of water. The buoy extends from the end of the streamer to the water's surface. A coupling connects the buoy to the end of the streamer and is breakable due to tension from the buoy obstructed at the surface of the water. A receiver associated with the buoy obtains location information via the buoy at the water's surface. The deployed device can reckon its location with an inertial navigation system in place of location information obtained with the buoy's receiver. Also, the buoy can be deployed at the surface of the water, and more than one buoy can be available for deployment should one be lost.

摘要： A vessel and method for breaking ice drifting in a predominant direction relative to an offshore installation such as a drilling vessel. The vessel is used to deploy an anchor in a position at a distance from the offshore installation and in a direction which, seen from the offshore installation, is substantially in parallel with the direction of movement of the ice. By means of the machinery of the vessel, the direction of the anchor line is adjusted and so is the orientation of the vessel relative to the anchor line to the effect that the propellers can be used to crush and dispose of the ice without using motive energy to hold the vessel against the pressure of the ice.

摘要： A system and method for clearing an approaching floating ice mass comprising locating a hydrocarbon development platform in a marine environment, and determining a direction from which the ice mass is approaching the hydrocarbon development platform. The method also includes providing an intervention vessel having a water-agitating mechanism associated therewith for propagating artificially generated waves towards a leading edge of the approaching ice mass to fracture the ice mass along the leading edge, thereby causing small ice pieces to separate from the ice mass.

摘要： An offshore floating production, storage, and off-loading vessel has a hull of generally cylindrical or polygonal configuration surrounding a central double tapered conical moon pool and contains water ballast and oil and/or liquefied gas storage compartments. An adjustable water ballast system induces heave, roll, pitch and surge motions of the vessel to dynamically position and maneuver the vessel. The moon pool shape and other devices on the vessel provide added virtual mass for increasing the natural period of the roll and heave modes, reducing dynamic amplification and resonance due to waves and vessel motion, and facilitate maneuvering the vessel. A disconnectable turret buoy at the bottom of the moon pool connects risers and mooring lines.

摘要： A semi-submersible vessel for offshore operations is suitable to be operated in icy waters and in ice-free waters. The vessel includes an operating deck, at least one lower hull, an essentially vertical connecting structure between the at least one lower hull and the operating deck, and a ballast system. The connecting structure has a water portion and an icebreaking portion arranged on top of each other. The vessel is configured to have an icebreaking draft for icy waters, and a water draft for ice-free waters in which the waterline is substantially level with the water portion. The icebreaking portion has a closed tapered contour. During the water draft, the collective area of the water portion of the connecting structure intersecting the water surface is smaller than the collective area of the icebreaking portion of the connecting structure intersecting the water surface during the icebreaking draft.

摘要： To keep the water around an off-shore installation (1) free from a harmful impact of ice, a vessel (5) is used to deploy an anchor (6) in a position at a distance from the off-shore installation (1) and in a direction which, seen from the off-shore installation (1), is substantially in parallel with the direction of movement (P) of the ice. By means of the machinery of the vessel, which preferably comprises azimuth propellers, the direction of the anchor line is adjusted and so is the orientation of the vessel relative to the anchor line to the effect that the propellers can be used to crush and dispose of the ice without using energy to hold the vessel up against the pressure of the ice.
