NACKS jv design

Lloyd’s Register (LR), Cargill International, Minerva Dry and Nantong COSCO KHI Ship Engineering (NACKS), have collaborated on the design of a Kamsarmax bulk carrier with methanol and rotor sail capability, as the result of a Joint Development Project (JDP) established already back in 2022 by the companies.

The new Kamsarmax design is said to provide a new energy efficient bulk carrier at a time when ship owners and operators must consider their environmental, social and governance (ESG) strategies in line with new and upcoming environmental regulations, which mandate the limiting of greenhouse gas (GHG) emissions.

The Joint Development Project included input on user requirements from one of the largest dry bulk operators, Cargill, and brings together the operational experience of ship owner Minerva Dry with the design expertise of leading Chinese shipyard NACKS. Lloyd’s Register notes that they acted as a trusted adviser throughout the joint development project as the sole classification society for the design of this unique vessel.

“Lloyd’s Register is proud to have collaborated on this JDP with Cargill, Minerva Dry and NACKS to design an energy efficient and future fuel ready Kamsarmax bulk carrier, bringing innovation to practice,” said Nikos Kakalis, Global Bulk Carriers Segment Director, Lloyd’s Register.

Chris Hughes, Decarbonisation Specialist, Cargill International said that “It’s been great to work closely with NACKS, Minerva Dry and LR on this project; they all brought a lot of knowledge and experience to the project; plus a willingness to challenge the status quo, and to consider new ideas and technologies. Rather than starting with a conventional fuelled design and adding on some limited “readiness” we essentially designed a methanol fuelled ship first and worked backwards from there for the methanol-ready version. The result is a design that is truly ready and feasible for conversion”.

“We are at a time when the shipping industry is undergoing a transformation process caused mainly by the rapid technological advancement and the requirements and targets set towards the decarbonization of our industry. As such, Minerva Dry is committed to working with industry stakeholders and business partners in developing solutions that will enable the decarbonisation of shipping transportation. We are very glad that we were given the opportunity to provide our insights and operational experience in this JDP that has resulted in the development of an optimised and energy efficient design of a Kamsarmax bulk carrier with futureproofing capabilities and sustainability elements, being at the same time commercially relevant today,” said Kostas Papadodimas, Technical Manager, Minerva Dry,

“It is really a big honour for NACKS to develop the new energy-efficient alternative fuel ready Kamsarmax Bulk Carrier with Minerva Dry, Cargill and Lloyd’s Register. Through the concerted efforts of all parties, the JDP project was successfully executed,“ said Mingfeng Lu, Technical Director, NACKS and added: “The methanol-ready dual fuel Kamsarmax BC is another breakthrough in developing “Carbon-Neutral” vessels in NACKS by comprehensive research on optimal arrangement of methanol storage tanks, fuel supply and refuelling systems. By optimizing the hull form and implementation of energy saving devices, the vessel provides significant improvement in energy efficiency comparing with the last generation of Kamsarmax BC. It can satisfy the requirement of EEDI Phase 3 by using conventional fuel, with the potential for greater improvement in it following the utilization of wind propulsion and methanol fuel in the future.”
