Surveys for Morro Bay Power Plant Marine Terminal Decommissioning
In June and October 2018, Woolpert conducted pre- and post-surveys for the Morro Bay Power Plant Marine Terminal Decommissioning Project. The objective of the pre-survey was to create a bathymetric grid of seabed, position and create a pipeline alignment where the pipeline was exposed, locate debris and objects on the seabed, and determine the extents of rock outcroppings and marine vegetation, all derived from the multibeam data. The post-survey focused on object detection of any man-made features or geological artifacts created or left from the decommissioning.
Woolpert completed a comparison of rock outcroppings and marine vegetation and derived a new bathymetric grid from the post multibeam data. Obstructions not related to the decommissioning were also noted for the safety of marine traffic and any marine construction in the area. A custom web-based geodatabase was a part of the delivered products. The geodatabase included features such as the pipeline alignments, boulders, kelp, rock outcroppings, bathymetry, contours, and survey boundary.
