Learn why buried disused cables may be difficult to detect and extract; why different seabed soils may require different tools; and how an out-of-service cable is recovered, cut, and laid clear of the new cable corridor.
Understand the limitations of PLGR; which vessel and deck arrangements will be most successful, and why it’s essential to ensure the vessel is provided with suitable tools for cable recovery.
Explore on why boulder grabs are used in some locations and clearance ploughs are used in others. There is also an opportunity to study calculations that establish the most economical method of boulder clearance on your project.
I am involved in managing subsea cable operations
I have experience as an Offshore Client Representative.
I am an experienced offshore or maritime professional
I am a technical graduate who wants to start an offshore career
I am a commercial fisherman or other stakeholder

Here are all the products that are included in your bundle.
In this first part of the course, we explore the theory, planning, and practical execution of route clearance for subsea cable projects.
In this course, we dive into Pre-lay Grapnel Run and Grapnel towing operations, cable protection, and reclamation route clearance operations.
Assess the knowledge obtained in the Route Clearence course completing the final exam module.
The importance of a thorough route clearance
Methods used to locate out-of-service seabed cables
Specific tools to remove buried cables
Various seabed conditions
How to conduct Pre Lay Grapnel Runs (PLGR)
Handling and disposal of recovered materials
Potential salvage and recycling
Pipeline and cable crossing or proximity agreements
Safe conduct of operations
To understand how to remove cables from the seabed, you need to know how they were installed, why some were deliberately buried, and how different soils will require a different approach when deburying them.
Some recovery methods work well when cables are on the surface of the seabed or shallowly buried, but are unsuitable for deeply buried assets.
During this course, we shall be studying the tools and methods used to locate and remove out-of-service assets from a new cable corridor. We’ll discuss exactly why we can't risk leaving them in the path of the new cable, and the potential consequences if they are allowed to remain in place.
We’ll be investigating why formal agreements are needed to cross or bring our tools close to a cable or pipeline owned by someone else, and the consequences if an in-service asset is damaged by our route clearance operation.
And investigate how information from cable installation reports can provide valuable intelligence when planning clearance operations, and finally, there will be a couple of real-life experiences illustrating just how not every job goes according to plan.
