Recently, CSA Trinidad had the opportunity to conduct a bathymetric survey of a private dockyard in Chaguaramas, Trinidad (Image 1). This private dockyard provides the oil and gas industry with a wide range of services, including vessel berthing. To ensure the provision of safe berthing, Trinidad Salt Company Limited (TSCL) recently contracted CSA Trinidad to carry out a bathymetric survey.
Single beam echo-sounder (SBES) and side-scan Sonar (SSS) technologies were used by the local field team, resulting in a depth chart and an ortho-mosaic (Image 2) that provided the client with a detailed representation of the seafloor and associated subsurface hazards that could jeopardize safe navigation. The data and analysis provided has been instrumental to the continuation of safe berthing services to vessels using the port in Chaguaramas.
