• Accelerated life testing on custom test

rig simulates 20+ years of service life

conducted under supervision of GL

• GL Certified April 2014 - Technical file

review (PPE and MD certificates,

reports, risk assessments,

maintenance schedules etc.) plus

8000 cycle rope test

Limpet®: One Product – Multiple Functions

Climb Assist/ Lift

Personnel Hoist

Rescue & Evac Kit

Fall Arrest System

Rope Access

Limpet® M5, a new class of offshore product designed to replace multiple

height safety and access systems and processes.

Limpet® M5 Offshore – Multiple use-cases

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

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

Limpet® M5 – Offshore Trial with MVOW at Thanet

Specially fabricated base unit

secured to gantry grating.

Using WTG mains supply

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

to lower 2nd line

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.

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
