A method of manufacturing an armour layer of a flexible pipe for transporting fluid from a subsea location and apparatus are provided. The method comprises winding a first length of composite tape to form a first section of the armour layer and positioning an end region of the first length of composite tape over an end region of a second length of composite tape to form an overlapping tape section. Heat and pressure is applied to the overlapping tape section to form a joined overlapping tape section in which the first length of tape is joined to the second length of tape such that the joined overlapping tape section has a lap shear strength of at least 11 MPa. The joined overlapping tape section and the second length of composite tape are wound to form a second section of the armour layer.

The present disclosure provides a filament winding device, which includes a helical winding device, a circumferential winding device, and a fixing device, a workpiece is clamped through the fixing device that drives the workpiece to rotate radially and move axially, the workpiece is performed helical winding through the helical winding device, and the workpiece is performed circumferential winding through the circumferential winding device.

A polar end ring mechanism for use with composite pressure vessels. The end ring is designed to support a pressure vessel during its formation via filament winding. The end ring helps define an opening at one of the polar ends of a tank. Spikes positioned along a portion of the end ring help prevent rotation or translation of the tank during formation and provide an improved mechanical lock with the tank body. A cap may then be secured to the polar end ring after formation in order to close the pressure vessel.

A superstructure-integrated backspray mitigation system for yachts including an aft spoiler secured to the vessels hardtop for directing airflow about the hardtop downwardly into the aft cockpit area to interfere with, mitigate and eliminate the natural reverse backspray created by the low-pressure region behind the yacht. The spoiler protrudes from the hardtop and includes at least one air ducting channel directing airflow at select angles into the cockpit area presenting a protective shield preventing the backspray from entering the cockpit. An optional pivotal panel member selectively enables operation of the spoiler.
