The Evolution BWT system begins testing on board the USCG

Cathelco announced that its Evolution Ballast Water Treatment (BWT) system has begun onboard testing for US Coast Guard type approval.

The system was installed on Svendborg Strait, a 1,085 TEU container ship owned by Carsten Rehder of Hamburg.

“From the start of this project to final completion, we appreciate Cathelco’s care and attention to detail, leading to a smooth and trouble-free installation. We are very pleased with the outcome and look forward to continuing our relationship with Cathelco” , said Julian Glogowski, technical director at Carsten Rehder.

The installation follows the completion of the onshore test phase at Marine Eco Analytics (MEA-nl).

The Evolution BWT system, based on a combination of filtration and UV technology, is being tested for type approval to the “live/dead” standard required by the US Coast Guard.

“The system on the Svendborg Strait was installed a day ahead of schedule in a very confined area, demonstrating the flexibility of the equipment,” said Cathelco Sales Manager Peter Smith.

The installation of the 500 m3/h Evolution system was undertaken in eight days at the Norderwerft site in Hamburg. The commissioning and training of the crew was carried out during the first voyage of the ship.

An important factor in the smooth operation of the facility was the use of Munchmeyer Petersen Steamship (MPC) as project managers.

“Upgrading a ballast water treatment system will always be difficult and demanding. The secret lies in the planning, communication and close cooperation with all parties involved, which made it possible to complete this installation one day ahead of schedule. We are proud to partner with Cathelco as demand for BWT systems accelerates,” said Stewart Richard Ayre, Senior Project Manager, MPC Münchmeyer Petersen Marine GmbH.

Land trial results are expected to be compiled and completed by November 2016. Onboard trials are expected to be completed by the end of March 2017 with the goal of obtaining U.S. Coast Guard type approval before the third quarter of 2017.

The Evolution system will replace the original Cathelco BWT system which was launched in 2014 and already has IMO approval and AMS certification. Past installations include systems for vessels ranging from ro-ro carriers to offshore supply vessels.

A key factor in the design of the Cathelco Evolution system is the ability to precisely adjust UV dosage based on seawater conditions. The system uses a UVT sensor to measure UV light transmission – the amount of UV radiation passing through a seawater sample before it reaches the UV chambers. This is a very reliable parameter for calculating the UV dose and ensuring economical use of energy.

Other important features of the system are stepless power control, intake manifolds designed to circulate water through a propeller to increase exposure time during irradiation, and a product-free cleaning system. chemicals.
