21 Agenda MacArtney overview Sample subsea infrastructure and components Case study Subsea challenges Q & A

22 Case Study: Andritz Hydro Hammerfest at EMEC Floating crane used to help deploy 1MW tidal turbine, HS1000 in August 2013 at EMEC site 50m water depth, 3km from shore 4-5 m/s currents

23 Case Study: Andritz Hydro Hammerfest at EMEC MAC provided 2 x ½ In line terminations, 2 bend stiffeners, termination work on site and installation Dynamic cable was 100m long Terminated into 3km 11kV electrical and fibre optic export cable 1MW/6.6kV cable, 110A per phase 80 hours for 2 technicians to conduct termination work on land

24 Case Study: Andritz Hydro Hammerfest at EMEC Crane barge used as deployment vessel < 2 hours to connect two halves offshore No diver support needed
