From sound science come wise decisionsTM
Since 2004, providing underwater noise impact assessment and marine mammal risk mitigation services to all marine industries worldwide.
Incorporated originally in 2004, OSC is a privately-owned international marine science company that specialises in the collection, analysis, and assessment of underwater noise and its impact on marine mammals and other wildlife. We provide marine consultancy services during different stages of Environmental Impact Assessments (EIAs) for the offshore energy (oil & gas, renewables, etc.), construction, fisheries, and defence sectors.
OSC is ISO certified for 9001:2015, 14001:2015, and 45001:2018.
OSC provide marine services to many sectors including windfarms, decommissioning, and seismic.
Uniquely, we invest a large portion of profits into production of high-calibre peer-reviewed scientific research papers, if clients release us from Non-Disclosure Agreement, NDA (OSC publications), intended to influence marine policy and permit/licence decisions with evidence-based investigations, so clients fund this endeavour indirectly when they contract OSC’s commercial services. Publishing industry data in journals ensures scientific transparency, impresses regulators, and improves clients’ environmental credentials. To the best of our knowledge, unlike any other environmental consultancy worldwide, OSC’s research staff are awarded up to 80% protected research time to write research papers from industry data; we effectively fund our own postdocs.
Since 2004, OSC has been conducting decommissioning field studies for a consortium of O&G clients. Research indicates strongly that offshore O&G installations/structures provide reliable feeding habitats for marine mammals, support diverse assemblages of species, and enhance reproduction of fish and invertebrates (e.g. Todd et al., 2009; Todd et al., 2016; Todd et al., 2018; Todd et al., 2020a; Todd et al., 2020b), which suggests that some well-placed offshore drilling rigs and production platforms should be left in situ at the end of their operational lifetimes.
In 2014, OSC undertook the definitive review on dredging and marine mammals on the back of supplying services to Shell for an ongoing project that has lasted over a decade (Todd et al., 2015).
