BLUESTREAM ORDERS COMPACT COUGARS FOR CENTRAL AND NORTHERN NORTH SEA OPERATIONS

Bluestream, who dominate platform inspection in the Dutch sector, aims to offer their experienced services to the UK Central and Northern North Sea Sectors with a Saab Seaeye-based, full scope inspection package.

By adding two new gravity-based Saab Seaeye Cougar XT Compact Zone II ROV systems to their fleet - a low-profile design of vehicle especially suited for fixed or floating platform inspections - Bluestream expect to assist their clients by bringing their experience and potential cost saving solutions to the UK offshore market.

The Cougar XT Compact version of the proven Cougar concept was chosen for its regulatory compliance in the Central and Northern North Sea Sectors and for its special compact design that makes it ideal for operating in and around platform structures.

Bluestream sees the platform-based inspection package offering considerable cost saving benefits, when compared to inspections carried out from ROV vessels.

Adding the two Cougar XT Compacts to their current fleet, brings Bluestream's total of Saab Seaeye vehicles to 22 systems.

The compact version of the Cougar design was chosen because its slimmed-down profile makes it easily manoeuvrable inside complex platform structures, whilst its powerful thruster pack helps cope with strong currents and turbulent waters.

Its low-profile design was specially conceived to minimise the effect of current by creating a reduced frame size, buoyancy and weight - and a thinner 17mm tether cable that reduces the effect of drag on the vehicle.

Whilst holding the Cougar Compact steady in cross currents and operating with precise manoeuvrability, its six powerful thrusters allow it to handle a wide array of equipment, despite its size.

Bluestream required a flexible equipment plan for their Cougars which, like all Saab Seaeye robotic vehicles, are designed for easy customisation and enhancement with third-party systems.

The two Bluestream Cougar Compacts will be equipped with a Seaprince sonar, Kongsberg cameras and an underslung hydraulic skid ready for fitting an array of third-party equipment which includes, but not confined to, the FlexiClean tooling, subsea water jetting, shear-cutter, subsea excavation pumps, subsea sensors and an array of CP systems.

The ease of configuration and integration is a key advantage of Saab Seaeye's design architecture says Bluestream who chose Saab Seaeye because they are the largest manufacturer of electric systems in the world with reliable and trusted technology that is familiar to their engineers.

SMART TORQUE TOOL ADVANCES AN ALL ELECTRIC FUTURE

A breakthrough in electric torque tool technology is set to further advance the capability of electric underwater robotic vehicles.

A new lightweight electric torque tool is being launched globally in a collaboration agreement between Saab Seaeye, the world leader in electric underwater e-robotic systems, and Australia-based Total Marine Technology (TMT).

New small self-calibrating class 1-4 torque tool to bring considerable savings to torque tool tasks with the use of smaller electric work vehicles.

to torque tool tasks with the use of smaller electric work vehicles.

The tool is smart, light, simple to fit, fast to set-up, has an advanced, high accuracy torque control system and can operate across the Saab Seaeye range of e-robotic vehicles, opening up new market opportunities.

Considerable savings will come from using compact electric e-robotic vehicles and electric tooling for tasks normally performed by much larger hydraulic vehicles.

No smaller electric class 1-4 torque tool exists on the market and with a singlehanded weight of just 24 kilos, it is around half the weight of a typical hydraulic torque tool, reducing the risk of manual handling injuries.

A major benefit for subsea operators is the tool's ability to adapt automatically to Class 1 to 4 fittings and torques whilst performing the integrity-critical task of opening and closing seabed valves and other torque tensioning tasks.

Torque accuracy is vital for operators needing to trust a system not to damage a valve when opening and closing. Electric torque systems are far more accurate over the whole torque range when compared to hydraulic systems and deck calibration is quick, repeatable and simpler, saving setup cost.

Helps avoid risk to older valves

An electric system can provide highly accurate small torque values so is extremely useful where there is an inherent risk of damage to older valves when turned, as they may be in poor condition.

The electric torque tool with its built-in drive and torque measurement is effectively self-calibrating across its full torque range, saving considerable operation and vessel time - and significant costs.

Current hydraulic torque tools operated by hydraulic vehicles are typically set and checked multiple times for a particular torque range before each dive, using a tested and certified calibration unit. Whereas in future the electric torque tool need only be calibrated by an independent body on an annual basis.

Accuracy and control are standout features with the TMT torque tool as the software-managed system allows much finer control and feedback than hydraulic systems. Operators control torque pressures by dialing in torque limits, speed, and number of turns and watch the response on screen immediately. Pitch and roll sensors in the tool aid rapid alignment during critical tasks.

The lightweight torque tool can operate in an underslung skid from small electric robotic vehicles such as the Saab Seaeye Tiger.

In addition to opening and closing valves the tool can be used in a wide range of tasks including installation and recovery of control leads and hoses, and closing and tensioning of connectors and bolts.

A typical hydraulic torque tool weighing around 50 kilos is generally held out in front of a vehicle by a heavy-duty manipulator, so needs a large vehicle.

As the TMT tool is half the weight it can be fitted to a smaller robotic work vehicle such as the Saab Seaeye Leopard - and can even be underslung to operate from an even smaller robotic system such as the Tiger.

Whilst on an inspection mission a compact electric vehicle can intervene to operate a valve, thereby avoiding follow-up intervention and reducing the number of excursions.

This pioneering development demonstrates how electric underwater e-robotics are increasingly undertaking serious intervention work as the market trends towards an all-electric future.

Subsea operators worldwide are expected to welcome a new electric torque tool that will enable electric underwater robotic systems to undertake an even wider range of subsea tasks and bring considerable cost savings.

Both Saab Seaeye and TMT see their collaboration as the start of a jointly beneficial relationship, with Saab Seaeye marketing the tool exclusively in the Northern Hemisphere and TMT in the Southern Hemisphere.

Saab Seaeye is the world's leading underwater e‐robotics company, with the most advanced range of tethered, autonomous and hybrid electric robotic systems, engineered to address the diverse range of tasks found across commercial, defence and scientific markets.

Total Marine Technology is a leading engineering and manufacturing company which produces the only Australian designed and built Work Class ROVs. They also operate a fleet of ROVs, manufacture innovative tooling designs, and provides offshore surveying for the global offshore drilling and production industry from bases in Perth and Kuala Lumpur.
