Oys­ter en­joys sum­mer re­fit

The Herald Business - - News Digest -

WAVE en­ergy com­pany Aqua­ma­rine Power has suc­cess­fully re­placed the cylin­der mod­ule on its Oys­ter 800 wave ma­chine as a com­pre­hen­sive sum­mer re­fit passes the half way mark.

The 23-tonne mod­ule was re­fit­ted to the 800kW test ma­chine – lo­cated at the Euro­pean Marine En­ergy Cen­tre in Orkney – in an op­er­a­tion that took just over two days.

“This is an im­por­tant way­mark on our route to re­li­able elec­tric­ity gen­er­a­tion,” says com­pany Chief Ex­ec­u­tive Of­fi­cer Martin McAdam. “This mod­ule in­cor­po­rates a num­ber of sig­nif­i­cant up­grades to the one it re­places – in­clud­ing new check valves, hoses and con­trol and in­stru­men­ta­tion.

“We have worked closely with sup­pli­ers Hunger Hy­draulik and Calder En­gi­neer­ing to make it ro­bust enough to with­stand the ex­treme forces it will ex­pe­ri­ence dur­ing op­er­a­tion.

“The Oys­ter con­cept clearly works – it is the only wave ma­chine to have op­er­ated con­tin­u­ously for three win­ters, and has gen­er­ated mul­ti­ple megawatt hours of elec­tri­cal power. Oys­ter can with­stand 100 per cent of all sea states, and the goal now is to gen­er­ate elec­tric­ity re­li­ably. This is a chal­lenge for the whole in­dus­try, and it is only through full-scale test­ing can we find out what works, what doesn’t and the evo­lu­tion­ary changes we need to make. This ex­pe­ri­ence is bear­ing fruit. Last year it took us a week to re­place a cylin­der and this time we worked with our lo­cal sup­plier Leask Marine to do the job in less than half the time.

“We’re now over half way through this sum­mer’s prod­uct im­prove­ment pro­gramme and are on still well on track for power pro­duc­tion later in the year,” McAdam con­cludes.
