Our client is an international public company working in the utilities sector. One of the client’s divisions was as an installer and maintainer of large scale windfarms. The nacelle of a wind turbine often contains many hundreds of litres of gearbox oil (a lower base oil).
Our client required expert advice on the production of Oil Spill Contingency Plans (OSCPs) which are often key to both combatting a spill effectively and obtaining an operating licence. In addition, our client had a need for second-tier response in the event of an incident.
AVADA Environmental provided the client with contingency planning support using a systematic approach to exploring what can go wrong and the steps that need to be undertaken in an emergency situation. We identified contingencies through a risk assessment process and showed the strategies needed to avoid or cope with them.
Our approach found and assessed oil spill risks, helping to ensure the correct arrangements were in place to manage spills. Shortly after provision of consultancy advice, the brakes of a turbine unit at one of the client’s installations failed leading to a gearbox overspeed resulting in catastrophic failure of the unit.
Nearly 500 litres of LBO was discharged over a wide area. The existence of the OSCP assisted the client in immediate installation of containment and mitigation measures. AVADA Environmental then provided on site assistance to verify that residual impaction of soil and groundwater did not pose a risk to receptors.
