Mitsui OSK Lines (MOL), MOL Drybulk, Oshima Shipbuilding, and Iknow Machinery have reached an agreement on joint research and development of the Iknow Delta Sail Crane, a wind assistance device that can be mounted on ships' cargo handling cranes and similar equipment to boost propulsion force.

The joint R&D project aims at reducing greenhouse gas (GHG) emissions from vessels while underway, by unfurling the sail placed in such locations as triangular parts of existing cargo handling cranes to use offshore winds to provide additional propulsion force.

Many MOL Drybulk-operated vessels are equipped with cargo handing cranes, and the company plans to study the installation of the Delta Sail on a broad range of ship types, such as bulkers, wood chip carriers, and multi-purpose vessels.

This is one of a number of initiatives under which MOL group is working to achieve medium-to long-term targets, ultimately aiming for net zero GHG emissions by 2050, including the Wind Challenger and Wind Hunter projects. The first Wind Challenger sail-assisted propulsion system is being installed on a newbuild coal carrier by Oshima Shipbuilding which is scheduled to start operation in 2022, supplying Tohoku Electric Power. Wind Hunter will combine wind assisted propulsion technology and wind energy converted to generate a stable supply of hydrogen.
