Imenco Guide Wire AnchorsI M E N C O H A S S U P P L I E D T H E S U B S E A I N D U S T R Y

Imenco anchors can be found all over the world - where ever oil and gas is recovered off shore. The systems are used both in shallow and deep water operations. The anchors are ROV/Diver operated for effi cient connection of guidewires to sub-sea 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. Anchor 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 guide post / 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 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 guidewire anchors are designed according to DNV standard for certifi cation no.2-22 Lifting Appliances.

The 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 padeye for connecting to the guidewire. All anchor models can be modifi ed to suit individual needs.

All standard guidewire 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 specifi cation up to the specifi ed models max shear pin capacity.

Features• Simple and reliable design

• Anchor is stabbed by its own weight

• Double self locking dogs - designed for equal load distribution

• Anchor can be released by ROV or diver

• Anchor can be re-used without retrieval to surface

• Inbuilt safety feature to prevent accidental release of anchor

Standard Anchor Options

• Lifting adapter

• Top padeye

• Safety sleeve

• Safety clip

For operations where accidental release may be critical, an optional safety sleeve or safety clip can be installed. Most of the standard guidewire anchors can be delivered with both safety sleeve and safety clip. The anchors can also be delivered with lifting adaptor and test load certifi cates. For additional information see Page 12 : Optional Features.

Slimline Guidewire 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 padeye connection to guidewire and more.

The main diff erence 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 anchors can be modifi ed to suit individual needs.

The lifting anchor has a diff erent design than the guidewire 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 guidewire anchors. All anchors can be modifi ed 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 anchor can be released.

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

Imenco Guide Post Extensions make it possible to temporarily increase the length of the guide post, thus providing necessary guiding length for BOP, XMT and other running tools. A standard Imenco GPE fi ts a guidepost with a top profi le according Imenco specifi cations.

In order to meet requirements for extending guideposts which have not been prepared for extensions, Imenco can deliver custom made guide post extension with any profi le on the bottom section to connect to the guide post. The Guide Post 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.
