SERVICES

At Flowline Specialists we design, engineer and manufacture a range of equipment that we use to safely handle flexible pipes, umbilicals and cables onshore and offshore for the global oil and gas, subsea and renewable industries.

We dedicate ourselves to reducing costs in this area by using specialist and innovative solutions. We are always open to new challenges, approaching our projects with efficiency and innovation in mind.

Deploying equipment around the world we provide services in flexible pipe and umbilical handling for subsea deployment, decommissioning and renewables.

We’ve worked on an extensive range of projects on a global scale. If you have a project you’d like us to work on please get in touch.


FLEXIBLE PIPE AND UMBILICAL HANDLING

Across the globe we have worked on projects in Europe Africa, the Middle East and Asia providing equipment and services to help our clients handle, move, transport and deploy flexible pipes and umbilicals.

At Flowline Specialists we design, engineer and manufacture cost-effective equipment solutions for safely handling flexible pipes, umbilicals and cables onshore and offshore for the global oil and gas and renewables industry.

DECOMMISSIONING

With our expansive fleet of equipment and experienced back deck personnel we can offer various methods for the decommissioning of products ,either by collection on to a reel and 300 Te hub drive for onshore processing or shearing product offshore with cut lengths directed into a bunded area.

Our offshore experience in decommissioning includes the recovery of umbilicals on to reels using tensioner and reel drive units and the offshore recovery and shearing of flexible flowlines on board the vessel.

Onshore we have been involved in moving 300Te Reels of product from the quayside utilising our unique Reel Carrier as well as transpooling and shearing of flowlines and umbilicals.  Our experienced Technicians commission and operate our equipment on or offshore worldwide

SUBSEA DEPLOYMENT

Flowline Specialists can offer many varied solutions for subsea deployment of flexible products. For large 8.6m / 9.2m Reels up to 300Te we can supply our Hub Reel Drive System complete with rails where multiple reels are to be deployed. We can also supply reels if required. Product on smaller diameter reels , 2m to 6m dia up to 125 Te , can be spooled and /or deployed from one of our shaft drive spoolers . We can manufacture whatever interface is required in order to secure the reel on the spooler. Tensioners can be supplied for both of these deployment systems for added control of the products.

Short lengths of flexible pipe, umbilicals or cable (jumpers) can be deployed through our subsea turntable pallet systems. We have pallets ranging in size from 2.8m dia through to 9.8m dia with max load capacity of 35Te, 17.5Te nett with a 100% safety factor.

The flexible jumpers are transpooled from their manufacturer supplied reel or coil on to one of our subsea deployment pallets using a pair of low level hydraulically driven turntables. Packing can be supplied to protect the product which is secured to the pallet with lever hoists and cargo straps. The loaded pallets are then transferred on to the client vessel for deployment. Each pallet has its own dedicated third party certified rigging.

Once subsea the product can be removed vertically from the pallet using vessel crane and swivel then laid down for installation. Where the water depth is insufficient to enable this method to be used there are alternative proven methods of removing the product horizontally from the pallet. A subsea turntable can be used to allow the pallet to be rotated and the product removed via a winch wire on the pulling head. The winch would be located topsides on client vessel or rig.

Another alternative would be to rotate the pallet on a swivel removing the product along the designated route.

We welcome the challenge of assisting clients with their deployment requirements.


RENEWABLES
