Delivery of travel-based safety, health and security training suitable for the risks identified for countries that Cefas travels to. The aim of the training is to offer greater skills and knowledge to anyone that travels overseas so that they are better able to work safely, securely and take care of their personal health and wellbeing and consider that of others that may travel with them. The courses may not be a prerequisite certification for staff to travel overseas or to be considered a gateway to enter or work in fragile environments. FCDO or other project funding routes may set the requirement for prerequisite SAFE training for certain projects and locations. Provision of the training in line with that mandated by FCDO provides assurance of appropriate content and that the training will meet the FCDO requirements. OTSSA (Overseas Travel Safety and Security Awareness) training content must be consistent with the requirements of the FCDO preferred SAFE training content.

The BEEMS (British EDF Estuarine and Marine Studies) programme is funded by NNB Generation Company (HPC) Limited. Through this programme, Cefas provide authoritative scientific information on the marine and transitional waters in the vicinity of potential new build nuclear power stations. Cefas require a supplier to conduct intertidal Remotely Piloted Aircraft (RPA) flights, in accordance with the civil Aviation Authority (CAA) guidelines, to monitor potential coastal change and intertidal algal coverage for the Hinkley Point C (HPC) Nuclear New Build project to meet regulatory environmental monitoring requirements. RPA flights and photography are required: (1) along the Hinkley Point foreshore, and; (2) at Combwich Wharf and the surrounding banks of the River Parrett. Flight/survey design and equipment specification must be sufficient for Cefas to create orthophotos (OPs) and Digital Surface Models (DSMs) with a Ground Sampling Distance (GSD, i.e. resolution) of 3cm/pixel or better (exceptions noted in Appendix 4 - Specification of Requirements).

The goal of the data study is to automatically detect actively leaking shipwrecks in a way that can be scaled up on a cloud platform to monitor hundreds of shipwreck sites simultaneously. The detections will need to be screened by an observer so detection accuracy must be balanced with the number of false positives produced, as a result of wind effects, natural spills or image speckle noise.

Clean Catch, funded by Defra, is a collaborative programme that is key to the UK Government's ambitions to help minimise and - where possible - eliminate bycatch of sensitive marine species, as set out under the ecosystem objective of the Fisheries Act and elaborated in the UK Marine Wildlife Bycatch Mitigation Initiative (BMI). Originally established in 2019, Clean Catch has now entered a second three year "expansion" phase, stewarded by a consortium of partners (Cefas, Arribada Initiative, MMO Consulting, Mindfully Wired Communications (MWC) and the Zoological Society of London (ZSL)) which runs until the end of October 2026. The overarching objectives of the current phase are to expand its scope and trials for monitoring and mitigation of bycatch and enhance its role in knowledge exchange within and beyond the UK. Cefas are leading the delivery of two Clean Catch monitoring and mitigation trials, the first is the "Southwest cetacean bycatch mitigation trial in inshore gillnets" which started in May 2024 and the second is the "North Sea whitefish fishery seabird bycatch mitigation trial" which is currently in the co-design phase with the Clean Catch consortium and the vessel owners, skippers and Producer Organisation. The trials are for research and development purposes and not for compliance monitoring. Both trials have a local Fishery Liaison officer assigned to them to ensure regular and effective communication between the consortium and trialists. Cefas will provide contact details and an introduction to the Fishery Liaison officer on Contract award. Data on sensitive species bycatch associated with participating vessels in the Southwest cetacean mitigation trial is primarily collected using Remote Electronic Monitoring (REM) and a skipper self-reporting smartphone application (the Clean Catch app). Although in the co-design phase of the North Sea whitefish fishery seabird bycatch mitigation trial, it is anticipated that REM will be the primarily scientific data collection tool. Whilst each trial is focused on mitigating the bycatch of a specific taxa (cetaceans or seabirds) information about all sensitive species bycatch events is recorded as part of the monitoring during the trial.

The BEEMS (British Energy Estuarine and Marine Studies) programme is funded by Sizewell C Limited. Through this programme, Cefas provide authoritative scientific information on the marine and transitional waters in the vicinity of potential new build nuclear power stations and require the Supplier to deliver the elements described below.  The purpose of this project is to provide bathymetric data at Sizewell to assess the geomorphological changes of the region, hence contributing to the ongoing monitoring of the Sizewell Coastline. These surveys are a regulatory requirement under the Development Consent Order’s (DCO) conditions and the Coastal Processes Monitoring and Mitigation Plan (CPMMP). Cefas anticipate 4 - 6 Multibeam Echosounder (MBES) bathymetric surveys to IHO Special Order (at a minimum) within the Greater Sizewell Bay (GSB) for a 12-month period between October 2025 and September 2026 (with the option to extend for up to 4 additional years), roughly following a quarterly schedule with the potential for additional surveys subject to requirements. Exact survey dates will be agreed between Cefas and the supplier during the pre-survey kick off meetings, however the timings for surveys are dependent on construction schedules so may be subject to change at short notice. We currently expect the first survey to be required in October/November 2025, with following surveys in approximately January 2026, April 2026 and July 2026. A Core Contract has been awarded to the top ranked Supplier with the intention that all required work will be completed by that Supplier. Due to the nature of the work and the risks associated, 3 Call-Off Contracts have also been awarded to the next 3 ranked Suppliers. These will only be used if the top ranked Supplier is unable to complete the services. We are therefore unable to determine the value of spend through each contract. 1st ranked Supplier to be awarded a 'Core Contract' -LandScope Engineering 2nd ranked Supplier to be awarded a 'Call-off Contract' -SEP Hydrographic Limited 3rd ranked Supplier to be awarded a 'Call-off Contract' -Njord Survey AB 4th ranked Supplier to be awarded a 'Call-off Contract' -Ocean Ecology Limited

The BEEMS (British EDF Estuarine and Marine Studies) programme is funded by NNB Generation Company Sizewell C (NNB GenCo SZC). Through this programme, Cefas provide authoritative scientific information on the marine and transitional waters in the vicinity of potential new build nuclear power stations and require a Supplier to deliver the element described below. To support the delivery of the BEEMS Programme, Cefas require the Supplier to provide aerial data collection using a Remotely Piloted Aircraft (RPA) in the Sizewell to Thorpeness region on a quarterly basis. It is anticipated that the first flight will be undertaken in March 2026 and the final flight in December 2028 (with extension options as per point 4). On occasion, additional flights may be required, therefore Cefas requests a day rate cost in Appendix 6, for flights of a similar nature in the vicinity of Sizewell area. The purpose of this work is to safely conduct regular RPA flights in accordance with the Civil Aviation Authority (CAA) guidelines at the above locations for the purpose of acquiring survey data to meet environmental monitoring requirements. The Supplier's flight team will manage the planning, notifications, and safe execution of each survey. The Contract implementation is expected to start February 2026, and the initial Contract period will end 31 December 2028, with the option to extend by 2 further periods of 12 months each to maximum end date of 31 December 2030.
