Guidepost Extension – GPE Model M4

The Imenco Guidepost Extension GPE M4 is used for installation on top of a guide post for temporary increase of the guiding length. The Imenco Guidepost Extension GPE has a receptacle on top for mounting of Guidewire Anchor or Lifting Anchor and will normally be deployed, installed and retrieved using the guideline. The lower end of the GPE has a lock down anchor and an internally profiled skirt section that mates the corresponding post top, thus providing a strong connection that can take tension and side loads. The Imenco Guidepost Extension GPE has a ROV operated release collar located just below the top of the GPE for lock down (L) and release/ unlock (U). The GPE model M4 has the same locking mechanism with shear pin function as used in the Imenco Guidewire Anchor and will automatically engage the guidepost top when the GPE is fully landed and the guideline is slackened. The shear pin will have a higher capacity before break than the corresponding shear pin used in the Guidewire Anchor.

The Imenco guidepost extensions have been extensively in use in the North Sea and other areas during the last 20 years and have proven to be very efficient and reliable.
The body of the standard Imenco Guidepost Extension GPE Model M4 is made from carbon steel, sandblasted and painted to meet offshore standards. The anchor parts, with locking and release mechanism are made from high strength stainless steel. A light weight version of the Guide Post
A Light Duty version GPE with aluminium body is also available for operations where the extension can be deployed and handled by the ROV.

The Imenco Guidepost Extension GPE delivery includes full documentation package with CoC, manufacturing record book, test reports, user manual and maintenance instructions.

The Imenco Guide Post Extensions have an outer diameter of 219,1mm (8” nom pipe) and can be delivered with different lengths and strength. For more details see GPE Datasheet. Special customized designs are available on request.
