A recently granted patent (Publication Number: US11668426B2) describes a helical strake system for a tubular structural member. The system includes a helical strake fin that is positioned around a portion of the tubular structural member. The fin is held in place by a series of couplers that are attached to the structural member. Each coupler has a slot that receives an upper portion of the helical strake fin and is removably coupled to a threaded attachment point on the structural member. The couplers are designed to position a portion of the fin perpendicular to the surface of the structural member.

In one embodiment, the couplers are attached to both sides of the helical strake fin, with the second portion of each coupler coupled to a respective attachment point on each side. The slot in the first portion of each coupler can either partially or substantially cover the sides of the helical strake fin. Additionally, the first portion of each coupler may include a set screw that applies force onto the fin.

The patent also describes a method for assembling the helical strake system. The method involves positioning the helical strake fin around the tubular structural member and attaching the couplers to the threaded attachment points. The first portion of each coupler is positioned to interface with the helical strake fin, and the second portion is removably coupled to the attachment points. The set screw in the first portion of each coupler can be adjusted to apply force onto the fin. The couplers can be adjusted along the threaded portion and can rotate about it.

Overall, this patent presents a helical strake system and a method for assembling it, providing a secure and adjustable way to position a helical strake fin on a tubular structural member. This system has potential applications in various industries that utilize tubular structures, such as oil and gas, construction, and transportation.
