600-passenger vessel for a German cruise company

Groundbreaking solution is a first

C-Job supported a family-owned cruise company when a ship needed Tier III modifications to become compliant with Norwegian Heritage Fjords and Mediterranean sailing regulations. This required a comprehensive upgrade to the vessel’s power system.

C-Job investigated various solutions for the client, including replacing the engines with new versions of equipment that were already being used, upgrading the electrical power system to direct current (DC), powering the generators directly from the drive shafts, and replacing the propellors. We also investigated the vessel design load cases, to see where emissions improvements could be made.

The results of our study concluded that in order to meet Tier III requirements, all seven existing engines on the cruise vessel needed to be replaced by four new engines to create a system that would run much more efficiently and meet the required emissions target.

C-Job was responsible for the full design scope and structural and mechanical engineering involved in the modifications, which also included creating space for battery installation in the future.

During the drydocking, C-Job provided assistance with onsite supervision and planning, and interface management on the build. As a result, C-Job collaborated with our customer from start to finish in the project, from the feasibility studies, to the concept, basic, and detail design, the drydocking and commissioning, and finally the sea trials of the vessel.
