In-Riser Products
Revolution Landing String System
Our API-17G qualified Landing String System includes an assembly of large bore hydraulically controlled valves for through-riser completion, installation and intervention. The valves provide enhanced cutting and post-cut sealing capabilities with the ability to rapidly isolate the well. The innovative design delivers superior
performance at a fraction of the cost of conventional systems.
Revolution Valve
Our API-17G qualified In-Riser Revolution shear and seal safety valves are available in a range of bore size and pressure variants including: 7-3/8” 10K, 6-1/8” 15K, 6-3/8” 15K and 5-1/8” 20K.
Slimline Revolution Valve
Our easily scalable shear-seal Revolution valve has been configured to an API-17G qualified, 4-1/8” 10,000psi, slimline in-riser valve with an outer diameter of 15-1/8”.
Revolution PowerPlus Valve
The API-17G qualified In-Riser Revolution PowerPlus valve is available in a range of bore size and pressure variants including: 7-3/8” 10K, 6-1/8” 15K, 6-3/8” 15K and 5-1/8” 20K.
The PowerPlus function adds an integrated gas accumulator to deliver ultra-fast cutting and sealing ability.
Upper PowerPlus Accumulator Module
The PowerPlus Accumulator module is an array of charged accumulator cylinders that provide fail-safe closure and local cutting power to a connected valve. The system is pre-gas charged at surface and energised subsea. The PowerPlus system is adjustable for power and cutting performance to suit the intervention media and water depth.
Lubricator Valve
API-17G qualified hydraulically operated lubricator valve with bi-directional pressure sealing and pump-through capabilities. Installed in the upper landing string assembly to isolate the wellbore from below and isolate the drill floor from the workover riser. Includes chemical injection capability. Provides passage and clearance of the LLSA controls umbilical.
Subsea Test Tree Ball Valve
Interventek's hydraulically operated subsea test tree ball valve is designed to deliver bi-directional sealing and strip through capability. The valve benefits from a lightweight and compact design and is fully API-17G validated
Subsea Test Tree Latch
The API-17G validated Subsea Test Tree Latch is a hydraulically operated arrangement of locking elements which allows disconnection from the SSTT after well isolation. The latch is orientated on the upper SSTT ball valve profile during relatch operations by a two-stage alignment prior to landing out. There is a secondary unlatch facility that can be activated by closing the BOP pipe ram and pressurising down the choke and kill line to an accurately pre-set burst disc and shuttle arrangement.
Open-Water Products
Open-Water Well Entry Valve - single cavity
The API-17G qualified Open Water Well Control Valve retains all the benefits of the Revolution in-riser valve in a structural housing suitable for the loads encountered in the open-water environment. The valve is ultra-compact and lightweight to enable ease of handling and deployment from a variety of vessels and even enables manual handling with guide ropes through the moonpool. The valve can also be configured as a retainer valve.
Open-Water Well Entry Valve - dual or triple cavity
The API-17G qualified Open Water Well Control Valve retains all the benefits of the Revolution in-riser valve in a structural housing suitable for the loads encountered in the open-water environment. The valve is ultra-compact and lightweight and is available in dual or triple cavity variants.
Bore Selector
Interventek's Bore Selector allows a monobore riser or riserless system to be used for intervention on a dual bore Xmas tree. Dual bore interventions can be carried out without returning the system to surface to realign the riser for annulus bore access, thereby improving operational efficiency.
Capping Stack
For emergency response well containment, our open-water deployed, API-17G 15,000psi, Capping Stack is 50% lighter, smaller and faster to mobilise and deploy compared to other available solutions. The lightweight and compact nature of this equipment is suited to contingency tree-on-tree installation during well entry operations. The design includes a hydraulically operated, compact shear and seal Revolution valve to replace the use of a ram. It will cut all common slickline, e-line, braided cable and coiled tubing rated to 130ksi min yield x 2.875" x 0.156".

Well Abandonment Valve
The well abandonment valve can be utilised as part of a large bore hydraulically controlled tree-on-tree system to provide a stress-free solution to open-water intervention operations. The valve weighs only 2.5 tons but provides heavyweight well protection in cases where the existing Xmas tree may be compromised. It is installed directly above the Xmas Tree prior to temporary suspension or abandonment and can be left in-situ for extended periods.
