摘要:
A system comprising a subsea structure beneath a body of water, subject to a water current; an installation vessel floating on the body of water; a line connected to the subsea structure and the installation vessel; and one or more vortex induced vibration suppression devices connected to the line, which have been lowered from the vessel to be installed on the subsea structure.
摘要:
A system comprising a subsea structure defining an interior of the system, the structure subject to a water current; a sleeve exterior to the subsea structure, covering at least a portion of an outside surface of the subsea structure; and a vortex induced vibration suppression device exterior to the sleeve.
摘要:
There is disclosed a system comprising a structural element, at least one helical strake about the structural element, and at least one ramp to provide a transition from the structural element to the helical strake.
摘要:
There is disclosed a system for reducing drag and/or vortex induced vibration of a structure, the system comprising a fairing comprising a dampening mechanism adapted to dampen the rotation of the fairing about the structure.
摘要:
There is disclosed a current tank system comprising a first current tank adapted to produce a first current in a first direction; a second current tank adapted to rotate to produce a second current in a second direction; a sample adapted to be exposed to the first current and the second current.

摘要:
Apparatus for controlling drag and vortex-induced vibration exerted onto a substantially cylindrical element of a fixed position subjected to a fluid flowing environment. Apparatus of the invention comprise a sleeve comprising an ultra-smooth surface. Methods for installing such apparatus onto cylindrical elements, and systems for controlling drag and vortex-induced vibrations in which a substantially cylindrical marine element has an ultra-smooth effective surface.
摘要:
Apparatus and methods for suppressing vortex-induced vibrations (VIV) of aquatic elements of underwater structures. The system includes use of a sleeve positioned around at least a portion of an aquatic element and at least one strake positioned along at least a portion of the length of the aquatic member. The apparatus further comprises copper to suppress the growth of aquatic organisms.
