AI answer written only from the numbered passages below
Safety supervision of Dutch offshore wind farms is shared between SodM (Staatstoezicht op de Mijnen) and Rijkswaterstaat, which jointly check compliance with the Wet windenergie op zee and the Waterwet 3. SodM's part covers human safety and environmental protection during construction, operation and maintenance of turbines and platforms, while Rijkswaterstaat covers use of the water system itself (navigation, cables, seabed use) 3. The Netherlands Coast Guard and the ILT also have roles at sea, so an operator can face more than one inspecting authority 3. SodM has become the regulator for offshore wind since the Wet windenergie op zee, alongside oil and gas, the gas network, geothermal energy and CO2 storage 2. Its own published figures describe roughly 45 inspectors, working through field inspections and office-based review of reports and work plans 1.
Not in the sources: The passages do not say how many inspectors Rijkswaterstaat, the Coast Guard or the ILT have, nor how many of SodM's 45 inspectors work on offshore wind.

Passage 1: How it inspects
SodM's own published figures describe roughly 45 inspectors who check whether mining companies, grid operators and offshore wind farm operators comply with the law, through both field inspections at sites and office-based (administrative) review of reports and the work plans that operators are required to submit before starting an activity. SodM expects its offshore wind supervision workload to grow substantially as installed capacity rises toward the government's 2032 target.

Passage 2: Mandate
SodM (Staatstoezicht op de Mijnen, State Supervision of Mines) is the independent Dutch regulator for safety and environmental protection in mineral and energy extraction: oil and gas production, the gas network, geothermal energy, CO2 storage and — since the Wet windenergie op zee — offshore wind. SodM operates under the Ministry responsible for climate and energy policy but issues its own inspection findings and enforcement decisions independently of the policy department.

Passage 3: Two-regulator model
Supervision of Dutch offshore wind farms is split between two bodies acting jointly: SodM and Rijkswaterstaat (RWS) both check compliance with the Wet windenergie op zee and the Waterwet (Water Act). SodM's part covers human safety and environmental protection during construction, operation and maintenance of turbines and platforms; RWS covers the use of the water system itself (navigation, cables, seabed use). The Netherlands Coast Guard and the Human Environment and Transport Inspectorate (ILT) also have roles at sea, so an operator can face more than one inspecting authority depending on the activity.
