Abstract: An elongate tape element (508), a flexible pipe body and method of producing a flexible pipe body are disclosed. The tape element has a cross-sectional profile comprising a body portion (510) for being positioned between collapse resistant tape windings such that each body portion lies at least partially in a gap (512) between adjacent collapse resistant tape windings (501); and at least one wing portion (516) extending from an end region of the body portion (510), the at least one wing portion (516) configured to span the gap (512) and respectively abut with a radially inner surface of an adjacent collapse resistant tape winding (501).

Abstract: A seal ring, a method of providing a fluid seal and end fitting are disclosed. The seal ring which provides a fluid seal between a polymer layer and an end fitting of a flexible pipe comprises an annular body that has a cross section comprising a first arm portion (500) and further arm portion (510) extending in a spaced apart relationship away from a body end portion (530).

Abstract: An end fitting (300), flexible pipe (100), riser (203), and method of producing the same are disclosed. A method of venting gas from annuli (312, 319) of a flexible pipe is also disclosed. The end fitting includes a first vent flow fluid communication path (311) and a further vent flow fluid communication path (318). The end fitting is capable of enabling gas to be vented from a flexible pipe body with two annulus regions (312, 319).

Abstract: A flexible pipe body and method of producing a flexible pipe body are disclosed. The flexible pipe body includes an inner fluid retaining layer; an armour layer provided radially outwards of the inner fluid retaining layer; and a buoyancy layer including a plurality of discrete elongate buoyancy elements provided radially outwards of the fluid retaining layer wound at a helical pitch angle equal to or more than 0 degrees and less than about 85 degrees to the longitudinal axis of the flexible pipe body.
