Edinburgh device developer Aquamarine Power is ramping up power production from its reinvigorated Oyster 800 near-shore wave converter in Orkney sea trials.

The company has notched up 6MWh over 60 hours of operations since the hinged contraption returned to service a fortnight ago, following a major programme of component upgrades.

Oyster (pictured) has achieved peak output of 435kW and logged 22 hours of continuous controlled power generation at the European Marine Energy Centre’s Billia Croo wave test site.

Aquamarine chief executive Martin McAdam said early indications are positive but Oyster’s recent achievements must be put in perspective.

“So far all of the replacement kit on the machine has performed as expected – but it is early days,” he said. “I think we have to be cautious given our experience with the machine and the variety of equipment failures that we have previously experienced.”

McAdam revealed that “additional problems” were encountered – and dealt with - during commissioning.

“As every engineer will tell you, commissioning issues are normal. Our controlled testing will continue,” he added.
