2 o are we? ea Electrical & Fibre Optic Connection Systems for Marine Energy pproach to subsea connection systems What Marine Renewables says is needed The Challenge Justification for wet mate methodology Status today? Where we are going tomorrow?

3 t Mate Connectors at are wet mate connectors and how do they work? ically, they are electrical Plugs and Sockets which can be eatedly connected and disconnected whilst they are under water more on this later...

4 alising The Challenge are we going to connect all this together? Floating devices Fixed foundations Removable Nacelles Multi-device platform Hubs Export cable

5 fining The Challenge o connect / disconnect (deploy / recover) of devices... subsea cables... in tidal / wave environment... that will last for life of the farm... in an affordable manner (Through Life Costs) stry messages Supply chain investment required. Single contract integrated solution.

6 bsea Connection Solutions y Wet Mate connector technology? ated 35-45% lifetime costs attributed to Installation and O&M (1) uced LCOE ( affordability ) through reduced Installation and O&M costs: ible cost effective alternative to Dry Mate or hardwired connectivity ntial benefits peed of deployment / recovery staged installation, devices/interconnections mproved H&S minimise activities at sea on the surface redictability of operations repeatable no over-runs esser dependence on weather window ower cable management minimise disturbance/excess length/damage risk

7 et Mate Connectors today t mate connectors exist! Thousands of connectors deployed. 11kV connectors first deployed 25 years ago. sting Range 690V through to 11kV Low Voltage auxiliary power Copper Ethernet Fibre Optic connectors a-high reliability heritage Unparalleled MTBF figures Deployment duty for whole life of farm

8 eting The Challenge ble, Wet-mate, Hybrid, Integrated Connection Management System (CMS) ltra-reliable = 25 years, zero maintenance, zero failure expectation et mate = Under-water Plug and Socket ybrid = contains MV, LV, FO all in one plug-in operation ntegrated = from subsea cable end to device internal cable Plug Example of Connection Management System termination nodes Socket

9 nnection Management System 8kV 4MW Length= 1500mm Height = 1000mm Width = 1000mm

10 nnection Management System - Deployment Powered lifting frame provides interface between payload and vessel craneage Negates the need for divers and ROVs to aid and observe subsea lifting operations Enables accurate positioning of payload Deployed using Work Class Multicat vessel

Introduction of new products, low-cost high volume High economies of scale Standardisation Low / zero NRE QTY

12 mmary The scale of future arrays will require a subsea connection infrastructure that will maximise the availability of wave and tidal devices Wet mate connector methodology is a prerequisite to affordable array/farm deployments Wet mate technology exists, is proven and is reliable With volume comes significant cost reduction Initiatives have been set up to identify and address gaps and barriers to the development of a wave and tidal industry. The proposed subsea connection system solution strengthens this position to move forward.
