One barrier affecting progress in the wave energy sector is detailed knowledge of the spatiotemporal distribution of waves in shelf sea regions, including their inter- and intra-annual variability. Here, a recent decade (2012–2021) of waves is simulated at high-resolution in the Irish Sea – a region with much offshore energy infrastructure. The spectral wave model SWAN is forced with ERA5 wind fields. There is a strong seasonal cycle in wave height and power. In all months except for July, large waves (significant wave height greater than 5 m) can penetrate into the northern part of the Irish Sea, but the most energetic region is the Celtic Sea, where monthly mean wave power exceeds 30 kW/m in December. In this region, wave power strongly correlates with the North Atlantic Oscillation (NAO) from September to March. To investigate the potential for co-location, i.e. to reduce costs through shared infrastructure, wave and wind power were compared at a leased floating wind site in the Celtic Sea. Over the simulated decade, r2∼0.5, demonstrating modest potential for co-location of wind and wave energy technologies in this part of the Irish Sea – considerably less favourable than other sites in the North Atlantic that experience greater swell.
Kizuizi kimoja kinachohusika na maendeleo katika sekta ya nishati ya mawimbi ni maarifa ya kina ya usambazaji wa mawimbi katika maeneo ya bahari ya shelf, pamoja na kutofautiana kwao kati ya mwaka na ndani ya mwaka. Hapa, muongo wa hivi karibuni (2012-2021) wa mawimbi ni simulated katika azimio la juu katika Bahari ya Ireland - mkoa na miundombinu mingi ya nishati ya pwani. SWAN ni mfano wa mawimbi ya wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi la wimbi. Kuna mzunguko mkubwa wa majira katika urefu wa mawimbi na nguvu. Katika miezi yote isipokuwa Julai, mawimbi makubwa (urefu mkubwa wa wimbi zaidi ya 5m) yanaweza kupenya katika sehemu ya kaskazini ya Bahari ya Ireland, lakini eneo lenye nguvu zaidi ni Bahari ya Celtic, ambapo nguvu ya wimbi ya wastani ya mwezi inazidi 30 kWm. Katika eneo hili, nguvu ya wimbi inahusiana sana na North Atlantic Oscillation (NAO) kutoka Septemba hadi Machi. Kuchunguza uwezekano wa co-kuweka, yaani Kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano, kwa mfano. Katika miaka kumi simulated, r2 <0.5 inaonyesha uwezo mdogo kwa ajili ya co-kuweka ya upepo na mawimbi ya nishati teknolojia katika sehemu hii ya Bahari ya Ireland <unk> kwa kiasi kikubwa chini ya mazuri kuliko maeneo mengine katika Atlantiki ya Kaskazini ambayo uzoefu swell kubwa.
