Project aim: Improved navigation and safety for all users
Previously each oyster farm in the harbour had its own marks indicating the boundaries of the site. These numerous site markings made navigation of the harbour difficult.
Unifying the sites under one marking scheme had the dual advantage of improving navigation of the harbour and providing efficiencies for the fish farmers.
Before: Visually ineffective in all weather and tides the poles made navigation of the bay difficult.
After: The new markings clearly indicate the perimeter of the production area.
Our methods: Working with industry
BIM’s regional officer and the oyster producers worked together to design a draft unified marking scheme for the sites.
- BIM surveyed the production area in the harbour to determine its extent and character.
- Consulting with the Commissioner of Irish Lights, the Marine Survey Office and the relevant government departments to determine the location and specification of each mark.
Once the design was approved:
- BIM provided funding towards the purchases of the marker poles and commissioned the construction of the bespoke supporting structures.
- Working with the local farmers we installed the new marks at the approved locations.
Public awareness signs are placed at key access points.
Seeing the benefits: Improved navigation and safety of the harbour
- Navigation of the harbour was greatly improved providing a safer environment for all users of the marine resource.
- The marks are included in the UK Hydrographic Office’s Admiralty Charts which informs visiting vessels of the perimeter of the production area.
- The marking scheme uses fewer, higher quality marks with a long lifespan, achieving efficiencies for the producers.
Building on the success of this project we are currently installing innovative unified marking schemes in other bays and harbours.
