Abstract
A vortex-induced vibration (VIV) suppression apparatus including a body having a wall dimensioned to at least partly envelope a tubular member in an interior area of the body; at least one extension member extending from the body; and an anti-fouling member mechanically coupled to at least one of the body or the extension member. A method of manufacturing a vortex-induced vibration (VIV) suppression device including providing a VIV suppression device having a body dimensioned to at least partly envelope a tubular member in an interior area of the body and at least one extension member extending from the body. The method further including attaching an anti-fouling sheet to the VIV suppression device.
Claims19
A vortex-induced vibration (VIV) suppression apparatus comprising:
- a body dimensioned to at least partly envelope a tubular member in an interior area of the body;
- at least one extension member extending from the body;
- and
- an anti-fouling member mechanically coupled to the body and the extension member, the anti-fouling member having a body portion in a shape of the body and an extension portion in a shape of the at least one extension member, and wherein the body portion and the extension portion comprise at least two separate sheets of an anti-fouling material having a surface which is positioned on, and in contact with, a surface of the body and a surface of the extension member, respectively, and at least one of the two separate sheets forming the body portion or the extension portion maintains the shape of the body or the extension member in the absence of the body or the extension member.
A helical strake assembly comprising:
- a helical strake having a body section and a fin helically arranged around the body;
- and
- an anti-fouling sheet coupled to the helical strake, the anti-fouling sheet having a body portion having a surface that conforms to, and contacts, a surface of the body section of the helical strake and a fin portion having a surface that conforms to, and contacts, a surface of the fin of the helical strake, and wherein the body portion and the fin portion of the sheet are preformed into a shape of the body section and the fin prior to being coupled to the helical strake.
A method of manufacturing a vortex-induced vibration (VIV) suppression device comprising:
- providing a VIV suppression device having a body dimensioned to at least partly envelope a tubular member in an interior area of the body and at least one extension member extending from the body;
- forming an anti-fouling sheet dimensioned to conform to a shape of the VIV suppression device, wherein forming comprises forming a body section dimensioned to conform to a surface of the body of the VIV suppression device and separately forming an extension member section dimensioned to conform to a surface of the extension member of the VIV suppression device;
- and
- separately attaching the body section of the anti-fouling sheet to a surface of the body of the VIV suppression device and attaching the extension member section of the anti-fouling sheet to a surface of the extension member of the VIV suppression device.
