Bond buy EC135 for wind farm servicing missions | Shephard Group
Surely the EC135 mentioned will need to be in "Offshore fit" to perform this sort of role . Note that it will be fitted with a hoist for transfer of personnel etc , does this require approvals from the CAA inorder to perform winching Ops ? Or can it just be done ?
Thought civilian winching was frowned upon in the UK unless its by a Civvy SAR or military machine.....
