Marine Shallow Water Seismic Survey

This Prior Information Notice is to signal an intention to commence market engagement with those within the relevant professional services market and to alert the market to potential forthcoming tender exercise(s). RWM intends to hold market engagement sessions through December 2021 and January 2022 with industry experts and suppliers interested in potentially bidding for the resulting commercial agreement(s). Please mail barry.purdy@nda.gov.uk for a copy of the contract technical specification. RWM aims to acquire two or more seismic surveys, with potential locations at inshore Allerdale District and Theddelthorpe (E. Lincolnshire). At this stage a broad search area has been identified within which RWM will undertake focussed 3D surveys of around 100km2. Whilst the actual survey area has not been agreed as yet, the broad characteristics of the surveys area can be described as follows. Allerdale district would involve acquisition within a tidal estuary environment within the English waters of the, Solway Firth with water depths ranging from 0-14m. Theddlethorpe would involve a marine acquisition in the inshore region (0-12nm) located between approximately between the Humber Estuary and The Wash. Water depths for Theddlethorpe are anticipated to be potentially between 0-20m. Both areas are anticipated to have tidal ranges between 4-7m as well as potentially high tide-related currents. RWM would aim to acquire both surveys within a suitable "weather window" to minimise adverse weather-related impacts on productivity.
