Above: Berge Bulk Debuts Newest Ship, Berge Mauna Kea, The First In A Series Of Four Hyper-Efficient Newcastlemax Vessels
Berge Bulk proudly announces the delivery of its newest vessel, Berge Mauna Kea, marking a significant addition to its fleet. Delivered from Imabari Shipbuilding Co. Ltd. at Saijo Shipyard in Japan, this brings Berge Bulk’s fleet to a total of 89 vessels, with a cumulative capacity of 15 million Deadweight Tonnage (DWT).
The Berge Mauna Kea is a Newcastlemax vessel, stretching 300 metres in length and 50 metres in width, with a carrying capacity of 211,599 DWT. The vessel sails under the flag of Isle of Man.
The vessel is named after Mauna Kea, a long-dormant volcano in Hawaii, USA. Mauna Kea is officially the world’s tallest mountain from base to peak, even though more than half of the mountain is underwater in the Pacific Ocean. It is approximately 10,205m (33,481 feet) in height, taller than Mount Everest’s 8,849m (29,032 feet).
Berge Mauna Kea is one of four sister ships ordered by Berge Bulk in 2021 from Imabari Shipbuilding in Japan. The other three sister ships will be delivered over the course of 2024.
The ship was designed and optimised through advanced numerical simulation and physical testing.
“Berge Mauna Kea’s modern design makes the vessel very efficient. This is achieved not only through a smaller, more efficient main engine, but also through careful consideration of various propulsion system components to maintain higher operating speed and optimal manoeuvrability.”
Paolo Tonon, Technical Director, Berge Bulk
Key highlights of its energy efficient design include:
  • Upgraded hull design, tailored to optimise performance and efficiency.
  • Advanced stern gear system with a rudder bulb and a custom propeller duct, enhancing propulsion efficiency.
  • The main engine is based on the latest development in fuel efficiency by MAN (series 10.6) with approximately 6% lower fuel consumption compared to its predecessor. This is achieved by a new low-load tuning, combining sequential fuel injection (SEQ) and exhaust gas bypass (EGB) tuning for optimising specific fuel oil consumption (SFOC).
  • The main engine’s installed power is 40% more efficient than similar vessels built in 2008.
  • The vessel is compliant with EEDI (Energy Efficiency Design Index) Phase 3 in advance of IMO (International Maritime Organisation) requirements.
“With these features combined, Berge Bulk expects yearly fuel consumption for Berge Mauna Kea to be more than 15% lower than other Newcastlemax vessels in our fleet.”
Paolo Tonon, Technical Director, Berge Bulk
Looking ahead, Berge Bulk plans to further improve Berge Mauna Kea’s energy efficiency. This includes implementing a power management system, propeller fouling prevention system, high frequency data collection system for performance monitoring, and an advanced voyage optimisation system.
James Marshall, Founder and CEO of Berge Bulk, who introduced the company’s ‘Maritime Marshall Plan’ for decarbonisation last year commented:
“Last year, we introduced WindWings on the Berge Olympus, showcasing our dedication to innovative technology. This year, we ordered two new ammonia-powered vessels demonstrating our commitment to zero carbon fuels. At the same time, we have not lost sight of the need to further improve our existing fleet, through a continued investment and upgrading programme. Berge Mauna Kea is a great example of such a hyper efficient ship ordered back in 2021.”
