Imenco Guide Wire Anchors can be found all over the world - where ever oil and gas is recovered offshore. The systems are used both in shallow and deep water operations. The Guide WIre Anchors are ROV/diver operated for efficient connection of guide wires to subsea structures.

The anchors are made from high strength stainless steel and have a long operational lifetime.

No extra tools required other than an ROV or a diver. The Guide Wire enters and locks to the post top/receptacle by its own weight and can be released and re-engaged without having to be recovered to surface. Standard release of an anchor from the guidepost / receptacle is simply for the ROV/diver to lift the Release Sleeve.

The system was developed in 1988 and continuous R&D has driven expansion into new areas of use.

Imenco Guide Wire Anchors are delivered globally to a variety of customers such as oil companies, drilling companies, subsea operators, subsea equipment manufacturers and many others. To date we have delivered over 1,000 units with negligible failure reported.

We have the facilities, competence and experience to provide service, maintenance and repair of all types and models of our products and have all necessary spare parts in stock. For ordering of spare parts and consumables please contact us using the contact information in this brochure.

The Imenco Guide Wire Anchors are designed according to DNV standard for certification no.2-22 Lifting Appliances.

The Imenco Standard Anchor is recognized by its slender body and wider head having a shoulder resting on the guidepost/receptacle top. This gives easy access to the release sleeve for releasing the anchor. The Release Sleeve is painted orange for easy recognition of the release point. All Standard Anchors can be delivered with either Wire Socket or a Pad-Eye for connecting to the guide wire. All Imenco Anchor models can be modified to suit individual needs.

All Standard Guide Wire Anchors are delivered with a shear pin. This allows the anchor to be released from the guiding system in the event of unexpected loads occurring in the system. The shear pin breaking load can be made to comply with client’s specification up to the specified models max shear pin capacity.

Slimline Guide Wire AnchorT H E S L I M L I N E G U I D E W I R E A N C H O R S H A V E S I M I L A R F U N C T I O N S T O T H E S T A N D A R D G U I D E W I R E A N C H O R .

The Slimline Anchor has the same advantages as the Standard Anchors, such as shear pin release, orange Release/Safety Sleeve, optional Pad-eye connection to guide wire and more.

The main difference between them is the design of the termination head. The slimline design makes it possible for the termination head to have the same dimensions as the anchor body. The shoulder of the anchor is designed to release via a push load by an ROV/diver. This allows all of the anchor to enter and exit the Guidepost/Receptacle ID where operational circumstances demand. All Imenco Anchors can be modified to suit individual needs.

The Lifting Anchor has a different design than the Guide Wire Anchors and is equipped with a solid steel pin instead of a (predetermined shear value) shear pin. The Lifting Anchor can be delivered with a pre-installed Safety Clip if required for the operation. The Lifting Anchor does not have a shear pin design and should therefore not be used in a guiding system in the same way as the Standard and Slimline Guide Wire Anchors. All Imenco Anchors can be modified to suit individual needs.

Safety Clip: Two types are available

1. Standard Safety Clip (pre-installed)

2. ROV installable

This ensures that the sleeve is locked in position. To release the Anchor, an ROV will have to remove the clip. Standard Anchors from GWA-22 to GWA-150 can be delivered with both Safety Sleeve and Safety Clip on request.

Safety Sleeve: Works as an integrated safety mechanism to prevent accidental release of the anchor. The Safety Sleeve will have to be “unlocked” before the anchor can be released.

The Guidepost Extension (GPE) is easy to operate and no tools other than a ROV are required. Release of the extension is the same as for Imenco Guide Wire Anchors, just lift the release sleeve. Available lengths according to customer requirements, standard lengths are listed below.

Imenco Guidepost Extensions make it possible to temporarily increase the length of the Guidepost, thus providing necessary guiding length for BOP, XMT and other running tools. A standard Imenco GPE fits a guidepost with a top profile according Imenco specifications.

In order to meet requirements for extending guideposts which have not been prepared for extensions, Imenco can deliver custom made Guidepost Extension with any profile on the bottom section to connect to the guidepost. The Guidepost Extension is equipped with a shear pin, which normally is set to 18’lbs, and can consequently be released by over-pull of the shear capacity in an emergency situation.
