Abstract
Disclosed is conduit anchor, an offshore system comprising a conduit anchor and a method of deployment. The conduit anchor includes a base section adapted for attachment to a conduit, and a conduit guide extending from the base section. In use a dynamic conduit extends along a dynamic conduit pathway range defined by the anchor, via the conduit guide. The conduit guide comprises a convex bend protecting surface region oriented towards the dynamic conduit pathway range which in use protects against over bending of the dynamic conduit.
Claims20
A conduit anchor comprising:
- a base section;
- and
- a conduit guide extending from the base section,
- wherein the base section comprises a conduit attachment for securing a static conduit or a static portion of a conduit to the base section,
- wherein the conduit anchor defines a dynamic conduit pathway range that includes the range of pathways extending distally away from the conduit attachment that a distal part of a dynamic conduit or a dynamic portion of the conduit can follow,
- wherein the dynamic conduit pathway range extends at least partially circumferentially around a dynamic conduit axis,
- wherein the dynamic conduit axis is a notional linear axis extending through a distal end of the conduit attachment,
- wherein the conduit guide comprises a convex bend protecting surface region,
- wherein the convex bend protecting surface region comprises one or more convex bend protecting surfaces, or wherein the convex bend protecting surface region is defined by a framework,
- the bend protecting surface region being oriented towards the dynamic conduit pathway range and distally from the conduit attachment, and the convex bend protecting surface region extending at least partially around a periphery of the dynamic conduit pathway range, and
- wherein the convex bend protecting surface region thereby defines at least a part of the dynamic conduit pathway range of the distal part of the dynamic conduit or the dynamic portion of the conduit and provides bend protection to the dynamic conduit or the dynamic portion of the conduit extending along the dynamic conduit pathway range through at least about 180 degrees away from the said notional axis.
An offshore system comprising:
- an installation on a surface of a body of water;
- a conduit anchor comprising:
- a base section;
- and
- a conduit guide extending from the base section,
- wherein the base section comprises a conduit attachment for securing a static conduit or a static portion of a conduit to the base section,
- wherein the conduit anchor defines a dynamic conduit pathway range, wherein the dynamic conduit pathway range comprises the range of pathways extending distally away from the conduit attachment that a distal part of a dynamic conduit or a dynamic portion of the conduit can follow,
- wherein the dynamic conduit pathway range extends at least partially circumferentially around a dynamic conduit axis, wherein the dynamic conduit axis is a notional linear axis extending through a distal end of the conduit attachment,
- wherein the conduit guide comprises a convex bend protecting surface region,
- wherein the convex bend protecting surface region comprises one or more convex bend protecting surfaces, or wherein the convex bend protecting surface region is defined by a framework,
- the end protecting surface region being oriented towards the dynamic conduit pathway range and distally from the conduit attachment and the convex bend protecting surface region extending at least partially around a periphery of the dynamic conduit pathway range, and
- wherein the convex bend protecting surface region thereby defines at least a part of the dynamic conduit pathway range of the distal part of the dynamic conduit or the dynamic portion of the conduit and provides bend protection to the dynamic conduit or the dynamic portion of the conduit extending along the dynamic conduit pathway range through at least about 180 degrees away from the said notional axis;
- and
- a conduit comprising the dynamic portion and the static portion,
- wherein the conduit is attached to the conduit attachment of the conduit anchor, wherein the static portion of the conduit extends from proximal of the conduit attachment to the conduit attachment and the dynamic portion of the conduit extends distally from the conduit attachment along the dynamic conduit pathway range, via the conduit guide, and to the surface installation.
A method for deploying a conduit anchor from an installation on a surface of a body of water, wherein the conduit anchor comprises:
- a base section;
- and
- a conduit guide extending from the base section,
- wherein the base section comprises a conduit attachment for securing a static conduit or static portion of a conduit to the base section,
- wherein the conduit anchor defines a dynamic conduit pathway range, available in use to a dynamic conduit or dynamic portion of the conduit extending distally from the conduit attachment via the conduit guide, and
- wherein the conduit guide comprises a convex bend protecting surface region oriented towards the dynamic conduit pathway range and distally from the conduit attachment;
- and the convex bend protecting surface region extending at least partially around the dynamic conduit pathway range,
- the method comprising:
- attaching a conduit to the conduit attachment, wherein the conduit comprises a static portion and dynamic portion extending from the static portion;
- and
- lowering the attached conduit anchor to the seabed, whereby when the conduit anchor is resting on the seabed the static portion of the conduit extends from proximal of the conduit attachment to the conduit attachment and the dynamic portion of the conduit extends distally from the conduit attachment along the dynamic conduit pathway range, via the conduit guide, and to the surface installation.
A conduit anchor comprising:
- a base section;
- and
- a conduit guide extending from the base section,
- wherein the base section comprises a conduit attachment for securing a static conduit or a static portion of a conduit to the base section,
- wherein the conduit anchor defines a dynamic conduit pathway range that includes the range of pathways extending distally away from the conduit attachment that a distal part of a dynamic conduit or a dynamic portion of the conduit can follow,
- wherein the dynamic conduit pathway range extends at least partially circumferentially around a dynamic conduit axis,
- wherein the dynamic conduit axis is a notional linear axis extending through a distal end of the conduit attachment, and wherein when the conduit anchor rests on a seabed, the dynamic conduit axis extends distally from the conduit attachment generally vertically away from the seabed,
- wherein the conduit guide comprises a convex bend protecting surface region,
- wherein the convex bend protecting surface region comprises one or more convex bend protecting surfaces, or wherein the convex bend protecting surface region is defined by a framework,
- the bend protecting surface region being oriented towards the dynamic conduit pathway range and distally from the conduit attachment, and the convex bend protecting surface region extending at least partially around a periphery of the dynamic conduit pathway range, and
- wherein the convex bend protecting surface region thereby defines at least a part of the dynamic conduit pathway range of the distal part of the dynamic conduit or the dynamic portion of the conduit and provides bend protection to the dynamic conduit or the dynamic portion of the conduit extending for between 90 and 180 degrees away from the dynamic conduit axis.
