At the beginning of December Dr Stewart Chalmers and John Polanski returned from their service trip for the DELOS subsea environmental monitoring platforms based in Block 18, offshore Angola.
This project allows BP to understand their impact of oil production in this region and differentiate between global, seasonal and anthropogenic changes. A longer time offshore in 2016 allowed the team to implement changes that allow the scientific modules to operate for two years subsea before the next data retrieval and servicing. With the oil industry in a period of constraint and budget restrictions, the extension of the operating period means a significant reduction in vessel time accrued by the project. The FSV, Ocean Intervention III, has two work class ROVs which are required for the retrieval and deployment of the modules at 1400m depth. One platform, the Near Field is situated 50m from the S3P2 wellhead in the centre of the subsea activity and the identical Far Field platform in a similar area of the Angolan Continental shelf, but 16km away from any offshore activity.
