Building a Fishing Trawler from an Offshore Supply Vessel

Allswater was involved from start to finish for the development of a new fishing trawler for a clam fishery. It was determined that due to the tight timeline for the vessel, it would need to be a conversion of an existing vessel as opposed to a new build.

The challenge was to provide a solution for entering a new vessel into the fishery with extremely tight timelines.

Faced with the urgency of the project, Allswater implemented a fast-tracked yet flexible approach:

  • Direct Shipyard Conversion: The chosen vessel was sent directly to the selected shipyard for conversion. Allswater negotiated a shipbuilding contract that allowed for rapid progress while maintaining flexibility to adapt as needed.
  • Concurrent Design and Construction: The detailed design was completed by Allswater as the work took place at the yard. Our team provided on-the-ground support, helping manage the conversion process in real-time.
  • Innovative Design: The unique concept developed for the vessel included:
    • New fishing arrangements and process factory setups
    • Innovative ideas to improve overall efficiencies

These improvements were successfully integrated into the existing vessel within the short timeline.

Key upgrades and installations included:

  • Removal of bulk compartments and installation of a new fish hold
  • Installation of a new accommodation block
  • Addition of a shelter deck for new processing factories
  • Implementation of a new fishing arrangement and equipment
  • Installation of a boiler and shaft generator
  • Overhaul of electrical and electronic systems
  • Installation of an ammonia refrigeration plant

The Belle Carnell was completed on time and entered service with production efficiencies that far exceeded expectations. It has been labeled as one of the most successful projects the client has undertaken. Recognized as the world’s most advanced shellfish harvester, the Belle Carnell’s success led to the client ordering a second conversion.
