The offshore wind industry is one of the great industrial success stories of the past decade. Global installed capacity is expanding at record pace, with G+ member companies reporting 79 million work hours in 2024 alone — a 27% increase from the year before.
But the injury data tells a more complicated story.
In 2024, the industry’s Total Recordable Injury Rate (TRIR) rose 7%, and its Lost Time Injury Frequency (LTIF) increased by 19%. A worker died during disassembly of a monopile upending tool. Manual handling was the leading cause of injuries across the entire sector — responsible for 121 incidents, up 26% from the previous year. Jack-up vessel operations accounted for 14% of all injuries, with incidents up 42% year-on-year.
A University of Strathclyde study found injury rates in offshore wind up to four times worse than comparable offshore oil and gas operations.
This is an industry growing into its safety obligations, and the hands-free load control gap is one of the clearest places to close.

The Three Highest-Risk Moments in Wind Turbine Installation
Wind turbine installation is a sequence of discrete, high-consequence lifts — each with its own specific hand hazard profile.
Blade Installation at the Hub
A turbine blade is typically 60–100 metres long and weighs between 10 and 35 tonnes. As it approaches the hub, the blade root must be aligned with the hub flange and the bolt circle. Workers must guide the root into position while the blade is moving, the wind is a variable, and the bolt holes are a crush zone. Hands placed near the flange face during this manoeuvre are in the most dangerous position on the entire installation vessel.
Nacelle Landing on the Tower Top
The nacelle — containing the gearbox, generator, and main shaft — weighs between 100 and 600 tonnes depending on turbine class. As it descends onto the tower top flange, workers must guide it onto locating pins and stud bolts. The margin for error is millimetres, but the consequence of a misplaced hand is measured in tonnes.
Monopile & Transition Piece Mating
The G+ 2024 report identified a fatality during monopile upending tool disassembly — confirmation that even the foundation installation phase carries lethal risk. During mating of a transition piece to a monopile, alignment forces are enormous and the convergence zone between steel components is unforgiving.
Manual Handling: The Leading Injury Cause No One Talks About Enough
The G+ 2024 report is direct: manual handling was the single leading cause of injuries in offshore wind — 121 recorded incidents. This category includes every moment where a worker’s hands are in contact with a load, component, tool, or structure during a movement task.
On a jack-up vessel or installation barge, those moments occur dozens of times per shift: equipment boxes being transferred to transition piece platforms, taglines being managed in live sea states, tools and components being positioned inside nacelles, drainage covers and hatch panels being lifted and relocated.
In every one of these scenarios, the HSF RiggerSafe Push/Pull Tool replaces hand contact with controlled, safe-distance interaction. For components being transferred in live sea states, the 72″ and 96″ variants provide the reach needed to control a load’s movement without standing in the swing arc. For nacelle-internal tasks, the 21″ compact variant fits where larger tools cannot.
The Non-Conductive Advantage
Offshore wind turbines are high-voltage electrical environments. The nacelle contains generators, converters, and transformer connections operating at voltages that make electrical proximity a standing hazard. The transition piece and tower base contain cable entry systems and earthing networks.
The HSF RiggerSafe fiberglass shaft provides non-conductive fiberglass construction — a specification that matters every time a worker uses the tool near electrical infrastructure during commissioning, maintenance, or component replacement tasks.
This is not a minor feature. For a push/pull tool being used near HV equipment in an offshore environment, non-conductivity is a safety-critical material requirement. Aluminium and steel alternatives fail this test entirely.
From Installation Vessels to Service Operations Vessels
The RiggerSafe tool family is relevant across the entire offshore wind operational lifecycle — not just initial installation.
On Service Operations Vessels (SOVs), technicians transfer equipment and tooling to turbine platforms in sea states that make every load a dynamic hazard. The 72″ and 96″ tools allow crew to control cargo landings from deck without stepping into the zone between the load and the platform edge.
During scheduled turbine maintenance — gearbox inspections, generator replacements, blade inspections — components must be moved within the constrained geometry of the nacelle. The 21″ and 24″ compact tools are designed specifically for this: fingertip precision in a space where a standard tool cannot be maneuvered.
As the industry scales to meet the energy transition targets of the next decade, the volume of operations will multiply. The injury risk multiplies with it — unless the tools change.
