Petronas Carigali Sdn Bhd installed a Light Weight Structure platform (D28D-A) and a 8 km pipeline at D28 Field, located 90km NW of Bintulu, offshore Sarawak, in a water depth of 35m (115 ft) and this project assesses impacts of this development after one year. Preliminary hydrographic surveys indicated there may be coral outcrops present along the pipeline route and/or the structure deployment site, that required a rapid visual inspection to ascertain the accuracy of this information. This project is a follow-up monitoring project following the initial pre-development EIA conducted in 2018.

The objective of this study was to undertake a visual inspection of several points in the vicinity of D28 to determine the condition of any corals which were detected during the original EIA study. We deployed a drop camera (UMS-7000) linked to a video recorder, and obtained SD footage of the seabed at those locations identified by the client. The camera was deployed at a number of stations in the vicinity of D28 to gather imagery of the seabed.
