摘要:
The invention relates to a fire-fighting device for cooling a vertical wall (10), wherein a horizontally extending profiled element (20) is arranged on the vertical wall (10). The fire-fighting device has a guide plate (30), wherein the guide plate (30) has at least a first region (32), which is arranged above the profiled element (20), a second region (34), which is arranged below the profiled element (20), and a third region (36), which is arranged at the level of the profiled element (20) and on the side of the profiled element (20) facing away from the wall (10). The guide plate has at least one fourth region (38) in the at least one second region (34), wherein the guide plate (30) has a distance from the wall (10) of 1 mm to 20 mm in the at least one fourth region (38).

Disclosed are a mooring system and a drill ship including the same. The mooring system according to an embodiment of the present invention includes a circular guide groove formed on a bottom surface of a hull and configured to use a center of the moon pool as a center thereof, a turret having a ring shape and inserted into the guide groove to rotate, and a bearing interposed between the turret and the guide groove to rotate with respect to the guide groove of the turret.

Provided is a locking apparatus for a damping device of a moonpool, which can automatically lock and unlock an opened state of the damping device of the moonpool. The locking apparatus includes: one or more first locking members installed in a sidewall of the moonpool; one or more second locking members installed in a side of the damping device; and a holding unit separably holding the first locking members and the second locking members when the damping devices are in the opened state.

A composite structural laminate comprises two outer metal, e.g. steel, layers and an intermediate elastomer core, e.g. of unfoamed polyurethane. The elastomer has a modulus of elasticity of greater than about 250 MPa and tensile and compressive strengths of at least 20 MPa. The strength of the bond between metal and elastomer is at least 3 MPa. The composite structural laminate member acts as a single member under load, buckling globally, not asymmetrically.

A ship for use in offshore operations, with one or more vertical openings (moonpools) in the hull, wherein the deck and/or hull bottom areas between or substantially between and/or otherwise adjacent the openings, are displaced relative to the rest of the deck and/or hull bottom areas of the ship to a position closer to the ship's transverse neutral axis. The area between the rest ot the other deck- and hull bottom areas and substantially the displaced area or areas is gradually stepped. Alternatively, the area between the displaced deck- and/or hull bottom area or areas at the openings in the ship and the rest of the deck- and/or hull bottom areas can be stepped in one or more steps, or be shaped as an approximately linear or arcuate junction.

A buoyant structure having a hull, a planar keel defining a lower hull diameter, a lower cylindrical portion connected to the planar keel, a lower frustoconical portion disposed above the lower cylindrical portion with inwardly sloping wall at a first angle, an upper frustoconical portion directly connected to the lower frustoconical portion, and the upper frustoconical portion with outwardly sloping wall, the inwardly sloping wall abutting the outwardly sloping wall forming a hull neck with a hull neck diameter. The buoyant structure having a main deck, a moon pool, and propellers attached to the planar keel, which are operated by a motor or a generator. The buoyant structure connects over a chambered buoyant storage ring.

Disclosed is a drillship having a vortex suppression block with a recessed flow stabilizing part in a moon pool. The flow stabilizing section is formed so that a bottom of the vortex suppression block that protrudes from a bottom of a hull toward a stern in the moon pool is recessed in an upward direction of the hull to stabilize a flow in the moon pool and reduce a variation in resistance of the drillship. The flow stabilizing section (30) is formed by partly recessing the bottom of the vortex suppression block toward an upper portion of the hull. The drillship having this configuration provides resistance performance improvement and flow stabilization of the drillship.
