  • Identification of required treatment rates

  • 3D scanning of available spaces to suit the treatment plant
  • Specification of the integration points with the existing Ballasting system
  • Perform required calculations for the vessel Class authority
  • Design equipment seats and support structures in accordance with Class requirements
  • Produce detailed piping isometrics
  • Identify removal/installation routes and work in way
  • Produce comprehensive drawings and integration guidance to allow for accurate installation costing and to minimise refit time through prior purchase and fabrication of system components
  • Produce an updated Ballast Water Management Plan for the vessel
  • Specify and design the integration of the systems into the vessel’s existing alarm and platform monitoring system

Longitude Engineering have completed the above tasks for a range of commercial operators on vessels as diverse as vehicle ferries and cable laying barges.
