Hyundai Mipo Gets DNV GL’s Nod for Con-Green 2000 Design

Classification society DNV GL presented Hyundai Mipo Dockyard (HMD) with an Approval in Principle (AiP) recognizing the technical feasibility of the new Con-Green 2000 vessel design under the new DNV GL rules.

The Con-Green 2000 project brought together partners HMD, MAN Diesel & Turbo, Becker Marine Systems, and DNV GL to develop a highly efficient, reliable and economic feeder design.

“With the Con-Green 2000 project we wanted to define the next generation of feeder vessels, with maximum fuel efficiency, high quality, reliability and lower maintenance costs and showcase the capabilities of Hyundai Mipo Dockyard,” C. G. Lim, Team Leader and Deputy General Manager, ECO Hull Form Development Team at HMD, said.

The hull form, propeller, general arrangement, midship section and scantling have been designed and optimized by HMD, using their software Hull Form Optimizer of Mipo (HOM) and Propeller Optimizer of Mipo (POM). The hull design is based on the new DNV GL rule set and the new IACS S11A and S34 requirements.

The design also incorporates the new Cross Over Rudder (COR) developed by Becker Marine Systems (BMS) as well the 6S60ME-C10.5 main engine from MAN Diesel & Turbo (MDT).

“The feeder market is continuing to grow in importance, especially in the intra-Asian sector, and we are seeing a wave of innovation in this area as yards and designers look to maximize efficiency and reduce environmental impacts,” Jai Oh Sun, project manager for the Con-Green project at DNV GL – Maritime, said.

The results of the hull and propeller optimisation provided power savings of some 7.5 per cent. Model tests on the design were carried out in June and confirmed the added performance, with the speed at NCR (nominal continuous rating) power with 15 per cent sea margin improved by about 0.55 knots in comparison to the original design.

Daily fuel oil consumption has also been improved by 12 to 16 per cent depending on the vessel’s speed, according to DNV GL.

The attained EEDI of Con-Green 2000 is 15.512. DNV GL said that this represents a value 10 per cent lower than similar sized vessels and fulfils the phase 3 requirements of the regulations.
