The Subsea 7 IRT Technical Solutions group is a leader in innovative interventiontechnology, providing specialist engineering expertise that guarantees support to ourremotely operated vehicle (ROV) services and construction/IRM activities.

The group has pioneered the design and operation of intervention systems and has longrecognised that simply replacing a diver by an ROV fitted with a manipulator is not theoptimum solution to underwater intervention.

This recognition has resulted in the development of a range of tooling packages andinterfaces, many of which have become industry standards, adopted by operators in awide variety of locations across the full range of water depths.

With a wide range of skills and expertise, the capability of the group can be summarisedas follows:

Project management and multi-disciplined engineering teams covering:- Mechanical design- Electrical/electronic design- Software design and development- Structural design for diverless connection systemsRemote systems design, manufacture and operation including:- Remotely operated vehicles and launch systems- Standard tooling systems and interfaces (API 17D and 17H)- Control systems- Diverless pipeline repair systems- Diverless connection systems- Component replacement systems- Diverless pig/launcher receiver systems- Stabplates

Dedicated fully equipped onshore bases support the company's varied underwateractivities and are also the manufacturing and servicing centres. The latest in subseatechnology is applied to the design, build and maintenance of remotely operatedequipment.

There now exists a wide range of standard and specialised intervention systems forperforming almost every subsea task that previously could only have been undertaken bydivers. The Subsea 7 IRT Technical Solutions group is a leader in the development andapplication of these systems.

As a result, we are able to offer a range of products and solutions to meet therequirements and specifications of our clients, from straightforward interface componentsto more complex installation systems, for safe, cost effective diverless operations in arange of water depths.

component change-out tool

The Component Change-Out Tool (CCOT) provides a means ofreplacing ROV retrievable components (e.g. control pods, insertchokes) and can be deployed on guidelines or as a fly-to-place tool.

As a fly-to-place system it is deployed to the seabed in a basket.The ROV c/w interface skid will then dock onto the CCOT, activatehydraulically operated latches to secure itself and then deploy anelectro-hydraulic stabplate connector to establish control of theCCOT functions. The ROV will then unlock the tool from the basket,fly it to place and dock it onto the subsea structure.

To remain neutrally buoyant during ROV fly-to-place excursions, thetool deploys and retrieves exchange weights on the structureinterface to an equivalent weight of the component.

The ROV Interface Skid consists of a neutrally buoyant aluminiumalloy space frame containing a hydraulic motor/pump transfer unit,12 litre over-pressure compensated oil reservoir, interface skid toCCOT docking latches, docking latch Emergency Disconnect andRelease System (EDRS) and multi-port electro-hydraulic stabplateupper half. The interface skid is fitted with sufficient buoyancy tomake it neutrally buoyant in sea water rated for 600msw.

The tooling control pod is located in the CCOT structure and linkedto the main ROV pod via the electro-hydraulic stabplate. Thismultiplexer pod manages all the signals to and from the CCOT.

tool deployment unit (tdu), dual point

Recognising that simply replacing the diver by an ROV fitted with amanipulator was not the optimum solution to underwaterintervention, Subsea 7 developed the Tool Deployment Unit (TDU).

Deployed from a Workclass ROV, the system has been designed toafford an ROV operator with little experience of intervention the bestchance of completing a task quickly and efficiently.

Using docking probes, rather than attaching with a grabber orsuction pad, the system is able to locate and stabilise the ROV in aknown position and precisely deploy a dedicated tool via an XYZmechanism.

The Tool Deployment Unit is self contained, being equipped with adedicated buoyancy module and control system. Interfacing to theROV is through mounting brackets, two hydraulic lines and oneelectrical cable. The ROV and Tool Deployment Unit are deployedusing a conventional ROV Launch System.

drill cuttings removal system

A new platform based drill cuttings recovery system has beendeveloped and tested by Subsea 7 on BP's NW Hutton. Thesystem involves the deployment of a 130 kW dredge pump systemand 4" OD recovery hose back to the topside processing plant.

A workclass ROV with a specially configured skid unit is then usedin multiple roles - not only does it hook up the delivery and suctionhoses to the dredge pump, it can travel within the radius of thesuction hose (45m for this application) to the work site. The ROVmanipulates the dredge head within the cuttings pile using itscamera and sonar systems.

An eyeball ROV, whilst not essential, is an invaluable aid to guidingthe operators. In this particular application, the system is designedto recover up to 100 m3/hr to match the re-injection capacity on theplatform. Solids ratio was up to 1:6 but a reasonable average wouldbe 10%.

The system was specifically designed to be installed on the NWHutton platform. However it has a modular format, which wouldallow relatively simple adjustment for use on the older platformswhere the volume of cuttings is a significant concern.

Dredge head

The dredge head can have a simple suction head or an interchangeable rotating cutter for harder conditions.

Deployment system

Delivery rate

75 - 100 m3/hr to the processing plant 70 m above sea level. Note the flow rate can be readily adjusted using a variablespeed drive to the dredge pump.

Dredge pump/motor

130kW motor driving a Warman International 4/3 centrifugal pump - power supplied through stand-alone umbilical winch.

Drill cuttings material

This is variable but the system can readily cut up to 25 -30 kPa cohesive material, although generally cuttings tend to berelatively free flowing silty sands. Maximum particle size to pass through the suction mouth and pump is 38mm. The designof the dredge head copes well with seabed debris, minimising pump blockages.

production sampling skid

This ROV deployed subsea Sampling Skid is designed to take

hydrocarbon samples from a live subsea production system with

zero emissions to the environment.

Fluid samples are required in order to determine fluid chemistry from

individual wells and to enable calibration of the subsea flowmetre.

The sampling system is mounted in a skid that interfaces to the

underside of a workclass ROV, the Sampling Skid is fitted with 2 x

5 litre sample bottles which store the hydrocarbon fluid as it is

tapped from the manifold and delivers it to topside at well pressure.

Subsea 7's standard Tooling Deployment Unit (TDU) is fitted to the

front of the ROV and is used to actuate isolation needle valves and

deploy the sampling hotstab.

The sampling system makes use of existing tried and tested

equipment wherever possible. The system has the potential for use

in other applications, such as hydraulic fluid sampling, injection

water sampling and pipeline fluid sampling.

hydraulic control panel

The Hydraulic Control Panel, when coupled to a torque tool,provides a means of accurately and predictably controlling thetorque and speed output of that tool.

It is used in conjunction with a Remotely Operated Vehicle (ROV)hydraulic system. It requires hydraulic solenoid valves from the hostvehicle to switch the functions on the control panel. There are threedifferent torque settings available, which are selectable from thesurface during the dive without retrieving the ROV.

There are additional function controls on the panel which cancontrol the pressure and flow available to three double-actinghydraulic cylinders or actuators. These are designed to control theSingle Point Docking System (SPDS) but can be used for otherapplications.

An intensifier is included which will provide an output pressure of upto 10,000 psi. Again, there is a facility for three surface-selectablepressure outputs from the intensifier circuit. The intensifier isisolated by a ball valve when not in use.

electronic control/feedback system

The Electronic Control/Feedback System shown in the photograph

above consists of two assemblies:-

1. The surface Control Console and feedback display.

This allows the applied torque and number of turns from the torque

tool in use to be monitored. These are measured by sensors fitted

to the torque tool and are 'fed-back' via the DIU interface (see

below) and a screened twisted pair in the host vehicle umbilical.

2. The Dedicated Interface Unit (DIU).

This is to the left hand side in the photograph. The electronics are

contained within housing to withstand the pressure of the seawater

at depth. This is mounted into the host vehicle frame and

electrically connected by a single interface cable. There are internal

vacuum loss and water ingress sensors contained inside the

housing.

The Control Console and DIU communicate with each other using a

dual multiplexer system. They are both of modular design and the

basic system shown above includes a keyboard assembly for

control of up to 12 solenoid valves and switching/focus control for

up to three tooling cameras. The system is also available with

proportional torque control.

linear actuator override tool

The Linear Actuator Override Tool (LAOT) is used to transmit axial force

to the stem of hydraulically actuated gate valves. The tool consists of

a bayonet profile end effecter which locks the tool to the valve interface

and activates the axial override force generated by the tool's piston.

The LAOT can be deployed by Subsea 7`s Tool Deployment Unit or

Alignment Tool. The tool consists of two discrete units, the tool itself

and a tool carrier which is used to deploy and retrieve the tool. A

rotary actuator within the carrier is used to lock the tool onto the valve

interface bayonet profile by rotating the tool through 45 degrees.

Once locked, and the valve actuated, the carrier can be detached from

the tool for an indefinite time period or until the valve is to be returned

to its original status, at which point the carrier is re-deployed and the

tool retrieved.

Variations of the tools depicted are available to cater for ISO 13628-8

figures 14, 15 and 16. Linear push interfaces type A, B and C in

addition to a double action hydraulic 'push-pull' version.

overshot tool

The Overshot Tool provides a remote means for mechanical andhydraulic connection to hydraulic pipework. It has been usedsuccessfully in instances where broken pipework from anaccumulator to tree has had to be re-established by a jumperconnection assembly. The tool has also been used to pressurisepipes to test the integrity of subsea hydraulic systems. In each casethe supply to the overshot tool was via a Remotely Operated Vehicle(ROV) compatible hotstab arrangement which allows for a re-entryconnection to top up control fluids.

The tool requires hydraulic power to actuate two functions, the firstof which grips the tube using a spring applied hydraulically releasedmechanism which must be pressurised before connection. Thesecond (optional mechanical mechanism), provides a hydraulic sealto the pipe with a one-shot seal function. After connection the toolwill maintain this hydraulic seal when disconnected from the ROV.

The tool can be manipulator deployed by a workclass ROV; whichwill require a fluid transfer unit to test the integrity of the connectionprior to any further connections. A cutting tool is also required priorto connection to ensure a swarf free sealing face.

The unit is robustly made from corrosion resistant materials and isspecifically designed for an unlimited depth rating and long term,maintenance-free immersion in seawater, with all moving partscontained in sealed, oil filled housing.

regan latch release tool

The Regan Latch Release Tool provides the means to disconnect

the guidewire from the Regan Latch should the guideline break.

The tool is stabilised on the latch by gussets which allow the

operation to be carried out regardless of the guideline position and

location of the break.

The tool consists of two shaped plates, the lower to locate itself in

the latch gussets, the upper to actuate the latch release

mechanism. They are brought together by a hydraulic function.

After the tool is positioned around the Regan Latch, hydraulic power

supplied by the Remotely Operated Vehicle (ROV) pushes the top

plate into the latch, thus releasing the guidewire.

The tool is manipulator deployed by a workclass ROV. For best

results the manipulator gripper is replaced with the tool and the

resultant spare hydraulic function is used to actuate the tool,

avoiding the need for a separate hydraulic supply.

The unit is robustly made from corrosion resistant materials and has

been developed for ease of use.

The AX Gasket Installation / Removal tool has been developed to

remove and install a gasket from or into its position in the

wellhead, prior to the connection procedure or re-establishment

of the tree assembly. It can also be used in instances where the

wellhead flange has an integral tubing hanger which precludes

normal access to the seal face.

The tool requires hydraulic power to actuate a total of four

hydraulic cylinders. Three of these operate the latching fingers (to

grip the gasket). The fourth cylinder operates the vertical travel of

the latching fingers (to pull or push the gasket from or into

position).

The tool can be manipulator deployed by a workclass Remotely

The stabplate and receptacle central mounting plates are designed towithstand separation loads induced by the hydraulic couplers andhouse the appropriate hydraulic couplers and electrical connectorsarranged as necessary to provide the services required. A fabricatedumbilical shroud provides protection for the umbilical jumper tails andtransmits any snag loads via the umbilical clamp.

The receptacle provides a means of positive engagement of thestabplate assembly and protection for the hydraulic couplers andelectrical connectors. The system is designed with integral alignmentmechanisms to avoid damage to the mating couplers and connectorsduring Remotely Operated Vehicle (ROV) make-up and break-outoperations.

The stabplate locks into its mating receptacle via a centrally locatedlocking mechanism which provides sufficient capacity to overcomemake-up loads at full working pressure. Controlled disengagement ofconnectors and couplers and release of the hub from the receptacle isachieved by `jacking` the assemblies apart by reversing thismechanism.

All materials are protected against external and internal corrosionunder all service conditions; particular consideration is given to thepotential for marine growth and other subsea matter, which have thepotential to significantly increase break-out loads over time.

emergency disconnect unit (edu)

The Subsea 7 Emergency Disconnect Unit (EDU) is a field proven

design used for emergency disconnection of subsea control

functions. Typical applications include work-over systems, control

umbilicals or large, basket deployed/underslung Remotely

Operated Vehicle (ROV) tool packages and so on.

The EDU is a combined docking/multi-stab interface which can be

retrieved and re-deployed subsea. The disengage/engage function

is hydraulically actuated and in the case of a work-over system

utilises two hydraulic control lines from the umbilical. Time delays

and sequencing of specific functions can be incorporated into the

control system.

The design is flexible; the actual number, combination and

specification of electro-hydraulic couplers can be varied to suit

client preference. Typical connectors include ¼ to 1-inch diameter

hydraulic connectors and 3 to 12 way wet compatible electrical

connectors.

The EDU features a combined test and transit frame.
