1 Offshore Wind Turbine Operations & Maintenance Solutions

2 Limpet - Next Generation Climb Assist Limpet - partnering with leading turbine OEMs onshore Senvion MM82 GE XLE 1.6 Vensys 1.5 Siemens SWT

3 Limpet Technology New Product Development Climb assist & fall prevention for use onshore. Climb assist, fall prevention, work positioning, rescue and evacuation for use offshore. Climb assist, fall prevention, work positioning, rescue and evacuation for onshore applications. Designed for heave compensated hoisting of heavy loads (multiple personnel/ materials) offshore.

4 Limpet M5 Development & Certification Limpet M5 based on L5 Design but with higher-spec components and sealing plus additional corrosion protection measures hours salt mist test Accelerated life testing on custom test rig simulates 20+ years of service life conducted under supervision of GL GL Certified April Technical file review (PPE and MD certificates, reports, risk assessments, maintenance schedules etc.) plus 8000 cycle rope test

5 Limpet : One Product Multiple Functions Limpet M5, a new class of offshore product designed to replace multiple height safety and access systems and processes. Climb Assist/ Lift Personnel Hoist Rescue & Evac Kit Fall Arrest System Rope Access

6 Limpet M5 Offshore Multiple use-cases A single Limpet M5 positioned appropriately on the WTG gantry can solve multiple access and safety problems and save huge expense for offshore wind farm operators Heave compensated materials/ personnel hoist & evacuation Personnel safety system for boat access & egress Blade & monopile inspection/ repair system Hoist rescue system for monopile and/ or main tower

7 Specially fabricated base unit secured to gantry grating. Using WTG mains supply Limpet M5 Offshore Trial with MVOW at Thanet

8 Limpet - Reduces Need for Technical Rope Skills Wire anchor strops of pre-determined length clipped straight into anchors to avoid requirement for knots & reduce dependence on IRATA level 3

9 Limpet Improves time to Rescue Remote rescue means rapid recovery with a single button press. Reduced risk as no need for rescuer to go to height. Injured but conscious Self-Rescue via RF remote Unconscious/ Incapacitated Buddy rescue via HID control Unconscious & power fails Manual unwind. UPS option Unconscious & primary line fails Rescue hub used to lower 2 nd line

10 Limpet - New Solutions to Offshore WTG problems Limpet working with clients to produce technical solutions to WTG access issues e.g. Base Section corrosion repair Limpet position (yellow) and top pulley (red) gives access to regions around the WTG Limpet unit installed on ladder supports access, egress and work positioning during maintenance
