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.

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.

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”.

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.

CobraKontrol Landing String Control System

A new rapid response subsea control system which reduces the overall complexity and cost of this critical equipment by an estimated 60%. The control system complements our Revolution Landing String System and interfaces with our integral valves to deliver fast-acting, failsafe reliability. Simplifying the control system leads to greater ease of operation and maintenance, reduces POB requirements and drives down time and cost. This high performing system is particularly suited to applications where project economics are challenging.

Open Water Revolution Valve 20K - Single Cavity

The API-17G qualified 20,000 psi Open Water Well Control Revolution Valve retains all the benefits of the in-riser valve in a structural housing suitable for the loads encountered in the open-water environment. The valve is 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 Revolution Valve 20K - Dual Cavity

The API-17G qualified 20,000 psi dual cavity 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.

Open-Water Revolution Valve 15K - Single Cavity

The API-17G qualified 15,000 psi 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 Revolution Valve 15K - Dual Cavity

The API-17G qualified 15,000 psi dual cavity 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.

Ultra-Lightweight Intervention System

Interventek has developed a new ultra-lightweight and compact open-water intervention system (ULWIS), which has been designed to minimise the stress applied to aging subsea Xmas Trees and wellhead infrastructure during operations. The ULWIS is especially suited to reducing the costs associated with well abandonment campaigns by providing operational and deployment flexibility, time-savings from ease of handling and reduced cost of ownership.

In its conventional EDP/LRP configuration the ULWIS utilises a 4-valve arrangement comprising an upper bi-directional ball retainer valve, latch, dual shear and seal valve block and lower bi-directional ball valve. The entire assembly weighs in at a mere 8T (10T with control interfaces and frame) and an overall length of less than 3.5m. The frame is 1.6m square, conveniently deployable through the rotary table of a rig and most vessel moonpools. Stacking the system in the derrick of a rig is an option and mobilisation and storage can be achieved using a conventional shipping basket.

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.

Revolution Shear-Seal Surface Valve

The Surface Intervention Valve is a large bore hydraulically controlled valve that forms a barrier between the Xmas tree and wireline/ coiled tubing BOPs during intervention. The valve provides enhanced cutting and sealing capabilities for all likely intervention media and its compact nature allows for ease of installation. Our unique Revolution technology is added assurance for post-cut seal integrity.
