![]() ![]() They are designed to accommodate any tolerances. It is then activated by ROV hydraulic pressure or hydrostatic pressure difference which provides a water tight seal with a typical pressure of 60 bar MAWP (Maximum Allowable Working Pressure). Optional modules include: check valve, dewatering seal, pig catcher, pig signaller and ROV Hot Stab hydraulic actuation.īolted on the end of the tool, the dewatering seal morphs to the internal pipe surface. For additional flexibility of recovery operations, the lifting tools can be abandoned subsea and recovered later.Ī dedicated DNV 2.7-1 / EN12079 cargo basket or handling skid enables to tool to safely and easily manoeuvred around offshore. The ball and taper grip is activated by ROV and the deployment arm removed to the surface. ![]() The deployment arm enables the tool to be held horizontally and inserted into the pipe by an ROV. The core tool elements are: Pipeline Recovery Tool, ROV deployment arm and handling skid. The current range of tools available is 2 Inch to 48 Inch diameter, although the ball and taper design makes any size possible. Modular Tool Designįirst Subsea offers a modular design approach to pipe handling tools, enabling greater customisation and faster response to tool enquiries. By customising the degree of grip, the tool is able to provide gentle handling for new pipelines, and overcome the dimensional inaccuracies caused by corrosion and build-up of waxing and hydrates with existing pipelines. The ball and taper multi-point grip is ideal for handling both new and existing pipeline, with a range of external and internal coatings. It is currently well over 100 units including internal and external recovery tools. The fleet is constantly expanding and evolving to meet the demands of customers, and offers a wide range of sizes and configurations. First Subsea has a dedicated team of PRT design engineers to ensure a rapid response to your enquiry and ensure tools are fully optimised to meet your project requirements.įirst Subsea has an extensive hire fleet backed by 24/7 response and rapid mobilisation in the case of a wet buckle. The pipe line recovery tool ranges typically from 2 inch to 48 inch (5 cm to 122 cm) diameter to meet project demands for both wet and dry buckle lift. Ballgrab® ball and taper Pipeline Recovery Tools (PRT) are utilised for the laying, decommissioning and recovery of subsea pipelines. ![]()
