Green Jade – for CSBC

C-Job supported CSBC with basic design and main crane integration for the Green Jade, the first heavy lift and offshore wind installation vessel built in Taiwan. The vessel, which features a crane with 4,000 tons of lifting capacity and DP3 capability, was launched by CDWE, a joint venture between CSBC and DEME Offshore, and entered service in 2023.
About the project

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.

C-Job continuously evaluates the maritime sector and its evolving requirements. Based on signals from the marketplace, we saw the potential need for multiple construction support vessels, where crane capacity is lacking and existing ships are aging.

Offshore wind feeder

C-Job Naval Architects has created an offshore wind feeder vessel for efficient transportation of wind turbine components, initially for the US market. By acting as a feeder vessel, our concept increases the efficiency of local wind turbine installation vessels (WTIVs).

Orion – for DEME

The Orion is a floating DP3 offshore installation vessel designed to support offshore wind parks with mega foundations and turbines. The vessel, which was a first of its kind, is a sister ship to the Green Jade. It was delivered to DEME in 2022 and currently sails around the world to perform installations for offshore wind projects.
