2 What Makes Us Different
One Company – A Multitude of Solutions Hydratight plays a leading role within the complex and changing world of subsea, providing innovative and unique services to improve cost effectiveness in this competitive industry.
MORGRIP® Morgip is a range of weldless mechanical couplings, which provide high-integrity connections for all types of metal pipe work. The Morgrip product has over 20 years of proven leak-free service history for permanent usage and can be used for all sizes and pressure ratings of metal pipes, in critical and non-critical service.
Hydratight’s innovative designs have produced a connection, which is the equivalent in strength and sealing performance to that of a welded joint. Available in a variety of formats, including standard flange termination and the unique pipe-to-pipe direct coupling connector. All formats suit specific applications whether for use on carbon steel, stainless steel or duplex pipes.
Benefits include: • High strength gripping mechanism using ball bearings which swage into the pipe’s outer surface • Patented metal/graphite sealing system • Designed for the life of the pipeline • No hot-work required • Safer, simpler and quicker than a welded joint • Full type-approval of DNV and Lloyds Register • API Monogrammed • Sizes up to 42" • Pressure rated up to 2500 lb • All water depths
3 HydraQuick Release System
Hydratight, the global leader in joint integrity, specialises in customised solutions for subsea applications. Such solutions have been implemented worldwide over the last 15 years, with initial projects into offshore West Africa. Hydratight has an international network of engineers linking directly into the centre of excellence for this technology in Paris, ensuring a quick and effective response to any customer enquiry.
As oil and gas production has ventured into deeper and deeper water, the requirement for remote activation in bolted applications has increased. This highlighted the need for reliable methods of remote disconnection devices. In response to this need, Hydratight developed the HydraQuick Release System. This system, operated via ROV hot stab, offers a fast, efficient and highly reliable method of remote disconnection (typical disconnection time is four minutes per stud instead of two hours when using ROV and torque tools).
HydraQuick Release System: The HydraQuick’s unique design utilises hydraulics to allow remote, fast removal from a tightened stud bolt. The principal characteristics are the following: • The design consists of a three segment nut set into a cage • Low pressure release; less than 120Bar (1,740psi) actuates the casing sleeve to move on the piston rod • The actuation movement retracts the outer cage and releases the three nut segments which immediately frees the nut from the stud bolt thread
4 This technology offers a significant increase in offshore operational time savings and consequently a cost reduction to the project. Hydratight is continually looking for new and innovative methods of utilising this technology within the subsea industry and welcomes opportunities to work with new and existing customers in developing any such solutions.
A Hydratight DVD included on the inside back cover of this brochure highlights the following applications: • Temporary closure: Girasol/Acergy, Jasmine/Acergy, Dalia/Technip & Greater Plutonio/Acergy in Angola • Bend stiffener removal tool: Moho Bilondo/Acergy in Congo • Release of clump weight: Technip • Quick structure dismantling: Bahr Essalam in Libya • Temporary flange protector: Greater Plutonio/Acergy in Angola, Moho Bilondo/Acergy in Congo and Agbami/Acergy in Nigeria
5 Joint Integrity
For over 30 years Hydratight has been supporting the bolted joint needs of the subsea industry. When it comes to torque and tension, no other company in the world has the engineering technology, experience and expertise of Hydratight.
AquaMax Subsea Tensioner The new AquaMax Tensioner from Hydratight is the only range of subsea tensioner to be specifically developed to generate the very high loads required for SPO/Vector compact flanges. This versatile range has been designed to be suitable for use with all standard flanges, including ANSI, API, Taperlok and SPO/Vector compact flanges ensuring maximum flange/bolt coverage: • High load capacity • Eight tools form a core range covering bolt sizes M24 (1") to M90 (3 1⁄2") • All tools are compatible with Aquajack quick fastening nuts
Aquajack Subsea Bolt Tensioner By tightening all the bolts simultaneously, a saving of up to 80% can be achieved over alternative methods. This provides the most cost effective solution to subsea bolt or stud tightening.
The Aquajack's unique reaction nut design: SPLIT NUT® allows rapid tool removal and application to long bolts: • 30mm (3⁄16") maximum piston stroke for tools AJ2 to AJ8 • 20mm (3⁄4") maximum for tools AJ0 and AJ1
HydraMax Topside Tensioner The HydraMax Tensioner is for topside assembly of flange applications for deep subsea use.
The HydraMax Tensioner’s compact flange design helps to achieve high bolt loads with a maximum stroke of 15mm and maximum working pressure of 1500 bar (21,750 psi).
Such flange applications with reduced bolt circle diameters include SPO compact flanges, custom designed stress risers, hull piping and customised SCRs.
The HydraMax Tensioner can also be used to install pullheads for risers, specialised connectors and ‘stopper’, ‘bear’, or ‘friction’ clamps, as well as standard ANSI, MSS and API flange systems.
6 Multi Stud Tensioner (MST) Hydratight’s MST offers significant time reduction in operation while simultaneously tensioning 100% of the bolts in a connection, providing the fastest and technically most efficient method of tightening any such connection.
Using lightweight materials combined with the minimum required number of segments keeps weight to a minimum, allowing easy and fast operation by a single operator.
Benefits include: • Design consists of a segmented annular ring with integrally machined, internally connected hydraulic chambers • Simple tool fitting as per a single tensioner • Only one single hydraulic connection is required for each segment • All hydraulic rams are energised simultaneously • Unique, innovative, asymmetric ram solution available for use in space-restricted environments
Designs can be to a basic standard or can be customised to include such features as: • Geared-nut driving sockets • Hinged carrying handles • Magnetic socket location • Overstroke preventors • Tooling position aids
RSLTM Hydraulic Torque Wrench Hydratight RSL hydraulic torque wrenches provide a comprehensive range of interchangeable hexagon and square drive heads, ideal when working on a variety of nut sizes on one or more applications: • Minimum maintenance; only three moving parts • Safe and durable • Compact and lightweight • Fast and versatile
7 Joint Integrity continued
Hydratight has established a dedicated Subsea Engineered Solutions department supported by a global centre of excellence. This enables Hydratight to respond quickly, working in partnership with customers (including being integrated into client project teams) to develop new, or improve existing applications to reduce offshore time and risk. As always, safety is an integral part of the solutions we deliver.
Nutsplitter The Hydratight Nutsplitter is a fast, sure and safe method to remove corroded or seized nuts without the need for hot cutting, chiseling or grinding. With a range of cylinders and interchangeable heads, the tool is designed to cover all ANSI flanges up to 36".
Features include: • Spring return cylinders for topside use • An optional double-acting hydraulic cylinder is available for subsea use • Cutting blade can be easily preset to prevent damage to bolt threads
Flange Puller The Hydratight Flange Puller is a compact device used to align or pull together flanges prior to the application of bolts and gaskets.
The system utilises a 150mm (6") stroke double acting hollow cylinder and can be operated with either wire rope or threaded bars. A uniquely designed jaw assembly is used to grip and release the rope and a four-way valve is incorporated into the unit to provide fast and simple operation and close operator control. Any number of cylinders can be used individually or simultaneously to provide constant load or controlled displacement.
Flange Spreader The Hydratight Flange Spreader utilises a high load compact hydraulic cylinder, together with a uniquely designed wedge and retaining mechanism to smoothly and evenly force open the flanged joint.
All tools are available throughout the world for sale, service or rental. Check the map on the back of this brochure for the details of your nearest Hydratight supplier.
