Description

Cefas require an automated surface vehicle (ASV) to undertake a shallow water multibeam bathymetric survey with 100% coverage of the area of interest (AOI) to IHO Order 1A (at a minimum) within the Greater Sizewell Bay (GSB) (Figure 1). The reason for using an ASV is two fold: 1. Maximise the western extent of the survey area: Two longshore bars exist in shallow waters within the AOI (important geomorphological features), with the inner bar being subaerial during some low tide periods. Accordingly, there is a high priority for the furthest landward coverage possible to be achieved by the survey, so that bathymetric data can be meshed to aerial topographic surveys of the beach, typically undertaken at low tide. We therefore require a shallow draft vessel capable of operating as close to the land sea boundary as possible, in order to maximise survey coverage of these important geomorphological features; and 2. Demonstration of the use of ASV survey methods: This survey will provide Cefas with a case study to assess the feasibility of using ASVs for future survey work. If demonstrated to be successful, additional surveys may be required pre and during the proposed SZC construction phase. These will be to monitor morphological changes in the longshore bars and to assess safe navigation and associated dredging requirements of the berthing pocket associated with the proposed beach landing facility (BLF) (a piled jetty structure used for landing construction materials).
