Embodiment Construction

[0162]Throughout this description, reference will be made to flexible pipes. It will be appreciated that certain embodiments of the present invention are suitable for use with a variety of flexible tubing. For example, certain embodiments of the invention may be used with respect to flexible pipe manufactured in accordance with API 17J and associated end fittings of that type. This flexible pipe is often referred to as unbonded flexible pipe. Also, and as described in more detail below, certain other embodiments of the present invention may be used with flexible pipe and associated end fittings for flexible pipe of composite type construction. This composite type flexible pipe and its manufacture are currently standardized by API. Such flexible pipes may comprise adjacent tubular layers bonded together.

[0163] go to figure 1 , it will be appreciated that the flexible pipe shown is an assembly of a portion of the pipe body and one or more end fittings, with respective end...

Abstract

A method and apparatus are disclosed for terminating flexible pipe body. The apparatus comprises an end fitting core portion (330), an end fitting termination portion (310) and a spacer ring member (335) locatable between the core portion (330) and the termination portion (310) for maintaining a whole anterior end surface of the core portion (330) and an opposed whole posterior end surface of thetermination portion (310) in a spaced apart relationship.

Description

technical field [0001] The present invention relates to a method and apparatus for terminating or re-terminating a flexible pipe body. In particular, but not exclusively, the present invention relates to end fittings comprising a spacer ring separating a core portion and a terminating portion of an end fitting to maintain those portions in spaced apart relationship. Background technique [0002] Flexible pipe is traditionally used to transport production fluids, such as oil and / or gas and / or water, from one location to another. Flexible pipes are particularly useful in connecting subsea locations (which may be deep underwater, ie 1000 meters or more) to sea surface locations. The tube can have an inner diameter typically up to about 0.6 meters (eg, diameters can range from 0.05m to 0.6m). Flexible pipe is generally formed as an assembly of a flexible pipe body and one or more end fittings. The pipe body is typically formed as a combination of layered materials that form a...
