Cathelco begins USCG shipboard testing
The Evolution system has been installed on the Svendborg Strait container ship which is owned by Carsten Rehder of Hamburg.
Peter Smith, sales director of Cathelco, said: “The system on the Svendborg Strait was installed a day ahead of schedule within a very confined area, demonstrating the flexibility of the equipment,.”
The installation follows the completion of the land-based testing phase at Marine Eco Analytics (MEA-nl), it was undertaken within eight days at the Norderwerft yard in Hamburg.
A key factor in the smooth running of the installation was the use of Munchmeyer Petersen Steamship (MPC) as project managers.
“Retrofitting a ballast water treatment system will always be challenging and demanding. The secret is in the planning, communication and close co-operation with all the parties concerned, this resulted in this installation being completed one day ahead of schedule,” said Stewart Richard Ayre, senior project manager, MPC Münchmeyer Petersen Marine.
It is anticipated that the results of land based testing will be compiled and completed by November 2016.
Shipboard testing is schedule for completion by the end of March 2017 with the aiming of achieving USCG type approval before the third quarter of 2017.
Cathelco Evolution system’s design allows for the ability to precisely adjust the UV dosage according to the prevailing sea water conditions.
The system uses a UVT sensor to measure UV light transmittance, this is the amount of UV radiation passing through a sample of sea water before it reaches the UV chambers.
Other important features of the system are its stepless power control, inlet manifolds designed to make the water flow in a helix to increase exposure time during irradiation, and chemical free cleaning system.
