Design modifications and integration of a powerful new crane
The Green Jade is a sister ship to the Orion, for which C-Job developed the concept design. However, with a different crane of 4,000 tons lifting capacity (versus the Orion’s 5,000 tons), C-Job naval architects and engineers had to adapt the design to meet different loads and ensure the vessel’s structural integration and stability. Compared to the Orion, the Green Jade was to be classed differently – ABS vs DNV – as well as having a double classification with Taiwan’s Classification Society (CR). This meant additional challenges had to be overcome, not only for the registration to the R.O.C. (Taiwan) flag, but also for operational considerations.
The project included integration of the Huisman-supplied main crane and its pedestal design, as well as the integration of propulsion thrusters and the auxiliary crane, which can be installed at multiple locations across the deck. The related intact and damage stability calculations were performed by C-Job using a NAPA model, and global FEA longitudinal strength checks were also performed.
