REDUCING COSTS THROUGH INNOVATION
Utility ROV’s background in commercial cargo recovery has led to an innovative approach to subsea operations.
Patrick Crawford, Managing Director commented; “All of our cargo recovery projects have been self-financed and carried out on a ‘no cure no pay’ basis. When you combine this with the inherent risk of the salvage operations, one poorly managed project could easily put you out of business.”
EFFICIENT AND COST EFFECTIVE SYSTEM UTROV has focused on developing an efficient and cost effective system that is capable of carrying out multiple operations in the offshore sector. This system eliminates the requirement to mobilise multiple sets of equipment for a single project, instead utilising the Utility ROV multifunction tool carrier and a versatile range of tools.
The operating platform is the greatest expense in most offshore projects, so a key requirement of the system is the ability to be installed on vessels of opportunity. This allows UTROV to utilise the most cost effective vessel for the project.
STREAMLINED TO INCREASE PRODUCTIVITY
All components of the system have been streamlined to increase productivity. High lifting capacity coupled with fast deployment and recovery times are crucial especially when working in deep water. The UTROV is capable of recovering a payload of 10t from 500mwd in under 16 minutes.
AMPLE REDUNDANCY
A high voltage electrical system is used to reduce losses in the 1000m umbilical and increase the subsea power output of the UTROV. Two 3.3 kV electric motors drive variable displacement load sensing hydraulic pumps offering 100% redundancy in the event of a failure.
The exception to this is the MFE (Mass Flow Excavator) as it requires the combined output from the pumps. As this power is at source it is capable of operating in up to 1000mwd with no power loss as depth increases.
The UTROV uses the same instrumentation as conventional ROV’s, 4 single mode fibres provide ample redundancy for any additional instrumentation to be easily installed. This high value equipment is protected within the robust frame enabling the UTROV to work in the most hostile of environments.
As with any business the key to the development of the system has been getting the right people. UTROV have a core team of multi-disciplinary staff that are able to look at the system as a whole rather than individual components. This understanding gained from involvement with the design, manufacture and operation of the UTROV system ensures that we can deliver safe, reliable and efficient solutions to subsea operations.
