摘要:
An apparatus and method for helically installing a vortex-induced vibration (VIV) suppression fin about a tubular. The apparatus may include an outer ring member dimensioned to encircle an underlying tubular and an inner ring member positioned concentrically inward from the outer ring member. The inner ring member is configured to rotate with respect to at least one of the outer ring member or the tubular as the outer ring member moves along the tubular. The apparatus may further include a fin guide configured to receive a fin and helically position the fin along the tubular as the inner ring member rotates. A method of installing a vortex-induced vibration (VIV) suppression fin about a tubular may include removably attaching a VIV suppression fin to an installation member. The installation member may be positioned along a tubular and moved about the tubular to helically position the fin around the tubular.
摘要:
A fairing for suppressing a vortex induced vibration (VIV) of a tubular including an encircling member dimensioned to encircle a tubular, the encircling member having a first side that extends toward a second side when the encircling member is positioned around a tubular. The fairing further including a support member positioned between the first side and the second side, the support member having a channel formed therein, and an opening to the channel is positioned between the first side and the second side. In addition, the fairing includes a tail member positioned within the channel, the tail member having a substantially planar surface that extends radially outward from the channel.
摘要:
A vortex-induced vibration (VIV) suppression apparatus including a base member having an interior surface dimensioned to at least partly encircle a tubular member; a fin protruding outward from an exterior surface of the base member; and at least one aperture formed through the base member, from the interior surface to the exterior surface.
摘要:
A collar for axially positioning a vortex-induced vibration (VIV) suppression device along a tubular is disclosed. The collar has an annular body portion and a plurality of support members extending in a radial direction from the annular body portion. The support members are annularly spaced around the annular body portion such that gaps are formed between the support members, the gaps being dimensioned to receive an auxiliary tubular positioned external to a main tubular around which the annular body portion is positioned.

An apparatus including a body dimensioned to surround a structure capable of experiencing a VIV, the body having a first section and a second section capable of being separated and positioned around the structure. The apparatus further including a blade member extending from the body, the blade member dimensioned to suppress the VIV of the structure when the body is positioned around the structure. A method of suppressing VIV about a structure by positioning a plurality of VIV suppression devices around the structure and wherein the plurality of VIV suppression devices cover less than 70% of a section of the structure.
摘要:
A system including a vortex-induced vibration (VIV) suppression device dimensioned to suppress a vortex-induced vibration of a support structure, the VIV suppression device having a base portion that encircles at least a portion of the support structure and a support member formed along the base portion. The system further including a collar having a body portion defining an annular channel and a flange portion extending outwardly from the annular channel, the flange portion dimensioned to form a receiving channel around the support structure for receiving the support member. The support member is received within the receiving channel to secure the VIV suppression device to the support structure and the VIV suppression device is capable of rotating around the support structure along the receiving channel.
