Cefas requires a pelagic trawler, suitably equipped to participate in an acoustic-trawl survey. The survey is part of the international IESNS (International Ecosystem Survey in the Nordic Sea), a collaboration between Icelandic, Faroe, Norwegian, EU and UK research institutes which has been conducted since 1997.
The survey is carried out to investigate distribution and migrations of the Norwegian Spring-spawning herring, blue whiting and other pelagic fish, and to produce a biomass index for herring and a recruitment index for blue whiting. The survey will cover the southern end of the distributional range of the spring-spawning herring population. Furthermore, data on the hydrographic conditions and plankton distribution will be obtained to investigate the possible effects of the ecosystem on the distribution and abundance of target fish species.
The estimated Contract value is £400,000 (excluding vat) per survey / per annum.
The initial Contract period will be for 12 months from 1 April 2027 – 31 March 2028. Within that period, the actual survey is for a maximum of 13 days within the period of 20/04/2027 – 20/05/2027.
Subject to confirmation of funding on an annual basis, further surveys in subsequent years may be required. If confirmed, these will be conducted within the same time period each year.
The Contract will therefore include extension options for up to 2 further years, to be confirmed on an annual basis.
Please note that there is no guarantee of further work beyond the initial Contract period.
The main objectives of the survey will be to:
Cefas will provide a minimum of 6 scientists to oversee the survey operations, working with the vessel to deliver the scientific objectives of the survey.
6.1. Survey activity
An acoustic-trawl survey to map and quantify herring and blue whiting. This will be performed by continuously (24h) running acoustic transects and carrying out ad hoc midwater trawling within the survey area.
| Lot | Title | Value |
|---|---|---|
| 1 | Lot 1 | £400,000 |
Additional objectives will include collection of plankton and hydrographical data in the study area.
6.2. Survey area and time of operation
The UK survey component will take place between Latitudes 62° and 69° North and Longitudes 13° West and 6° East (see full specification in bidder pack for total survey area and example of UK component in green).
The survey will be a total of approximately 13 days and will be conducted within the period 20/04/2027 – 31/05/2027. The vessel must be available for 13 consecutive days (this excludes time to calibrate the echosounders in a suitable port as well as transit from berth port to requested mobilisation port) within this period and ideally commencing at the start of this period.
Embarkation and disembarkation is required to take place in a Scottish mainland port e.g. Fraserburgh, Peterhead.
6.3. Vessel specification
6.4. Permissions
Cefas will be responsible for obtaining all necessary permissions and licences to undertake survey operations within the survey area of operation; however the Supplier may need to provide Marine Management Organisation / The Crown Estate with the details of specific survey activity ahead of commencement of work to fulfil licence requirements.
Cefas may require the Supplier to provide information relating to permissions in order to publish a Kingfisher Bulletin notice.
6.5. Common Marine Inspection Document (CMID)
An in-date valid CMID will be required from an accredited CMID inspector before the commencement of the survey.
Cefas reserve the right not to progress with the contract if the proposed vessel(s) fails to meet the requirements of the Cefas vessel assurance standards.
Where the vessel will be carrying out lifting or fishing/trawling procedures as part of the contracted work the vessel assurance process will require them to demonstrate the safe operation, effective maintenance and compliance of the equipment in line with any relevant maritime legislation.
6.6. Special provisions relating to safety of taking scientists to sea
The Supplier must demonstrate that the vessel and crew can safeguard the health, safety and wellbeing of project staff. Project staff from Cefas will be under instructions to ensure that all standard safety at sea items and procedures are adequate before each sailing. Confirmation to sail will be subject to physical inspection/survey of the proposed vessel and successful sign-off of the vessel assurance process and documents which will be facilitated by Cefas staff.
It is a requirement of the MCA for the skipper to give an explanation to project staff of the vessel risk assessment and health and safety regime, including the stowage and use of life saving appliances, the procedures in an emergency, and escape routes before embarking on each voyage. Safety briefings shall be carried out prior to departure (e.g. procedures in event of fire, medical emergency, abandon ship etc.).
The Supplier must procure and maintain the following insurances for the duration of the contract:
The Supplier is required to have a pro-active approach to health and safety and provide details of any certifications held.
Cefas request that an initial report of any accidents or near miss incidents (to any person on board) that occur during contract delivery, are to be reported by telephone or email within 24 hours to the Cefas Scientist in charge (SIC).
In addition to the initial report above, Cefas require a full report on all accidents or near miss incidents is delivered at the end of the contract, when all services are complete.
The Supplier is required to have appropriate Environmental and Quality Management systems and processes in place to provide assurance to Cefas. The Supplier will provide details of any certifications held such as ISO9001 and14001, but these are not mandatory.
Following completion of each survey, the Supplier will provide Cefas with a report which includes; the vessel engine capacity, distance travelled and fuel used. The Supplier will also provide a statement to confirm any incidents of lost gear or disposal of gear, and how this was managed ethically and sustainably
