CCGS Isle Class

BYD-Naval Architects won the contract to integrate a Hamann HL-CONT Plus 025 sewage treatment system aboard the Isle Class vessels of the Canadian Coast Guard: Ile St. Ours, Caribou Isle, and Cove Isle. The project required comprehensive structural, mechanical, and electrical modifications, ensuring compliance with environmental regulations while optimizing the system’s complex functionality within the vessels’ existing layouts.

The structural engineering scope involved designing and modifying the existing foundation to accommodate the new sewage treatment system. Given the compact design of the Hamann unit, our team carefully analyzed spatial constraints to ensure efficient placement while maintaining accessibility for maintenance tasks.

The mechanical engineering, included modifications to the vessel’s piping and discharge systems, integrating the treatment unit into the existing wastewater management infrastructure. This included a complete redesign of the black and grey water piping systems and how they are transferred to the sewage treatment system.

Beyond design work, BYD-Naval Architects provided shipyard support, ensuring the installation adhered to specifications and best practices. We collaborated closely with shipyard personnel and Canadian Coast Guard representatives, offering technical oversight and addressing challenges when needed.

Through this project, BYD-Naval Architects successfully enhanced the environmental performance of the Isle Class vessels, demonstrating our expertise in marine system integration and compliance-driven design solutions for the commercial marine industry.
