Anchor Releasable Guidepost – GPAR

The Imenco Anchor Releasable Guidepost GPAR can be used on subsea structures where there will be no, or very limited, side access to the post top or the post receptacle. This post is handled using the guideline with extended Lifting Anchor. The extended anchor engages an internal shoulder connected to a release rod operating the post’s locking dogs. The post locking mechanism is of same proven design as used for the Top Releasable Guidepost GPAR and will automatically engage the post Receptacle RTR type when the post is fully landed and the guideline is slackened. For the normal guidewire operations standard guidewire anchors will be used. The post is supplied with GPE profiled post top to enable installation of Imenco Guidepost Extension.

The Imenco Anchor Releasable Guideposts GPAR are made from carbon steel, sandblasted and painted to meet offshore/ client standards. They are supplied with full documentation package, including CoC, manufacturing record book, test reports, user manual and maintenance instructions.

The Imenco Anchor Releasable Guidepost GPAR can be delivered with different diameters, lengths and strength according to client specifications. For more details see GPAR Datasheet. Special customized designs are available on request.
