Ennsub delivers DEEP 4000 deepwater deployment systems

Ennsub has completed the design and manufacture of two innovative workclass remotely operated vehicle (WROV) deployment systems which have been designed and manufactured for ROVOP and are due to be installed into a new build, tier one pipelay vessel early in 2015.

A number of senior figures from the oil and gas industry were given an insight into Ennsub’s DEEP 4000 system recently before visiting its new Teesside premises.

The demonstration showed the equipment’s capabilities, which includes a unique cable handling solution designed to maximise umbilical lifespan, particularly in ultra-deepwater and other high-fatigue applications such as active heave compensation. The system also has a high-speed electric winch with full active-heave compensation, semi-dipping extendable A-frame and transfer skidding system for large tool packages. A new control system and human machine interface (HMI) provides the client with a fully integrated and centralised operating station.

Ennsub’s integrated ROV launch and recovery solutions offer a next generation approach to ROV deployment, particularly in supporting top-tier subsea construction assets where reliability and performance are required.

Scott Macknocher, Managing Director said: “We believe this technology highlights our ambition to become a leader in the field deepwater deployment solutions worldwide. The equipment presently under delivery offers a number of novel solutions to many of the current problems experienced by the ROV operating community.

“These include industry-leading umbilical handling, compact deck footprint, reduced hydraulic hosing and many enhanced control features which will have been designed in co-operation with experienced ROV operators and which will reflect the need for safety and reliable operation.”

The company offers a range of deep and ultra-deepwater deployment solutions for ROVs, subsea modules and bespoke subsea packages in addition to a suite of pipeline installation-related products and pipeline repair solutions. It also boasts an operations-led approach to design to suit the specific requirements of its customers.

Earlier this month, Ennsub was awarded a contract worth £2 million by Benthic to build a newly enhanced and portable Launch and Recovery System to complement the latest addition to its seabed drilling and geotechnical drill fleet.
