OSRL Water Column Monitoring Equipment

The WCM Equipment was developed by CSA Ocean Sciences Inc. (CSA) and has been integrated into operational plans and desktop exercises conducted in the U.S. and internationally since 2014. CSA is a marine environmental consulting firm with 50 years of experience serving the environmental needs of the offshore oil and gas industry. The WCM Equipment is offered through the OSRL SWIS Capping subscription to complement existing equipment designed for the use of SSDI as a response option when relevant. Even if SSDI is not required as a response option, the WCM Equipment provides useful instrumentation and tools to enable sampling and monitoring in deep-water settings for Operational and Scientific Monitoring Plans (OSMP).


Designed for mobilization on an offshore supply vessel, the WCM Equipment includes two 8 ft × 20 ft containers certified for offshore use by Det Norske Veritas (DNV) and the American Bureau of Shipping, powered during stand-by, and functioning as shipboard workspaces during deployment. The equipment in each container enables in situ sampling and monitoring in water depths up to 3,000 metres and provides real time in-situ data collection of subsurface water quality, which can be used to characterise the extent and limits of subsurface oil, and to monitor the efficacy of subsea dispersant.

The WCM Equipment is self-contained and mobilization-ready, with an integrated Launch and Recovery System (LARS) consisting of a 30-horsepower winch, A-frame and skid (DNV certified by Lloyd’s post-construction). The system is equipped with an electrotechnical cable to provide power and communication to the sensor and sampling equipment.
