Top Releasable Guidepost – GPTR

The Imenco Top Releasable Guidepost GPTR is used on subsea structures where there will be side access for the ROV at upper part of the post. The post is easily deployed, installed and retrieved using the guideline with standard Guidewire Anchor or Lifting Anchor. A release ring, which is located just below the top of the post, is easy to operate by ROV (or diver) for lock down (L) and release/ unlock (U) of the post. The post locking mechanism will automatically lock to the post Receptacle RTR type when the post is fully landed. The GPTR type posts have been widely operated in the North Sea and other areas during the last 10-15 years and have proven to be very efficient and reliable.

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

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