A Robotic Arm Manipulator for Offshore operations

For immediate release
28th August 2017

A new European Project named Kraken has started. The project received €350.000 through financing of OCEANERANET (Ocean Energy European Research Area Network) and gathers four partners of three different countries: WavEC Offshore Renewables and Instituto Super Técnico (Portugal), SIANI (Canary Islands) and CADFEM (Ireland).

The partners encountered in Lisbon, Portugal, at the end of July for the kick-off meeting and established the first actions of this new promising project.

Ocean energy technologies are moving steadily from laboratory scale models to real scale prototypes and arrays of converters. In order to be reliable and cost-effective, all these devices require regular Underwater Inspection Repair and Maintenance (IRM) services. Nowadays the solutions of underwater inspection and maintenance are industrial class ROVs and divers. Since the current ROV solutions still do not provide a sufficiently low cost and high precision for many of the IRM operations (underwater welding, welding inspection, fouling removal, painting, valves operation, sacrificial anodes replacement, connecting underwater plugs, etc.), specialised divers are still being used by the industry, despite the high-risk and high rate of mortality.

Due to the lack of tools specially designed for the Ocean Energy technologies, the industry is obliged to use standard solutions that are commonly used in the oil and gas industry, which have a higher cost.

The Kraken project aims to tackle the existing gap of the ROV tools specially designed for the Ocean Energy sector needs with the objective to reduce the high OPEX costs associated to the underwater IRM. The development of a maintenance system that can be installed in any inspection/general class ROV and carry out all the services currently performed by divers and a good range of those performed by larger ROVs will decrease logistics and consequently the operational costs for the underwater IRM services by 50%.

Kraken brings mature proven telemanipulation technologies from surgical rooms into the deep sea. Kraken’s objective is to improve the performance level of the offshore IRM operations by completely avoiding the human hazard of using divers and to reduce significantly the costs of work class ROVs by using smaller inspection ROVs deployed from much smaller vessels at a fraction of the cost.
