Hyundai Mipo Dockyard (HMD), Hyundai Global Service (HGS), and DNV presented the results of a joint industry project (JIP) on eco-friendly marine solutions that can help shipowners and managers to comply with tightening environmental regulations.
he results of the second phase of the “Green tankers towards 2050” project explores the possible options for a 50,000 DWT MR tanker to comply with incoming IMO & EU greenhouse gas (GHG) regulations over the lifetime of the vessel.
In 2019, DNV and HHI group launched the first phase of the “Green tankers towards 2050” project, which focussed on developing low and zero carbon pathways for VLCCs and MR tankers. In the second phase in 2022, HMD, HGS and DNV studied the design and operational options of a 50,000 DWT MR tanker and presented potential pathways towards two compliance goals: Meeting current IMO GHG reduction targets in the lifetime of the vessels and reaching full decarbonization by 2050.
We believe our research results, including engineering and operational solutions, will support ship owners in developing their future strategy for ship operations and fleet renewal
said Inho Lee, Head of engineering basic design department of HGS.
During the seminar, HGS introduced retrofit solutions for carbon dioxide reduction and showed how digital transformations can improve operational efficiency. HMD demonstrated how their latest 50K MR tanker design, with LNG dual fuel and Wind Assisted Propulsion System (WAPS), could lead to a 50% reduction in attained EEDI compared to the EEDI reference line. In addition, HMD projects that the new design can exceed the CII C grade ranking into 2040.
The data analysis of MR tankers built by HMD and currently in operation were showed to be highly efficient in real world conditions. We are confident to offer ships that both meet or exceed future environmental regulations, while remaining economical over the long-term
stressed Yi Hyo Chung, Head Engineer at HMD.
DNV conducted an assessment of the economic potential of different fuel strategies using the DNV FuelPath Model. This resulted in an estimation of the total cost, under a variety of possible fuel price and regulatory scenarios.
By applying DNV’s FuelPath Model to MR tankers, DNV found that MR tankers can operate on very low sulphur oil (VLSFO) until the early 2040’s, while meeting the current IMO ambitions, explained Christos Chryssakis, Business Development Manager at DNV Maritime. However, as requirements can become stricter, fuels like LNG and methanol can offer additional flexibility and options for compliance. Furthermore, the use of wind assisted propulsion systems can help reduce a vessel’s environmental footprint, he added.
