Borealis and IINO Lines sign long-term charter contract for the Oceanus Aurora, a custom-built state of art LPG vessel

Borealis, one of the world’s leading providers of advanced and sustainable polyolefins solutions, and IINO Kaiun Kaisha, Ltd. (IINO Lines), a global leader in maritime transportation headquartered in Japan, announce the long-term charter of a custom-built vessel, the Oceanus Aurora.

  • New liquefied petroleum gas (LPG) dual-fuel vessel is equipped with emission-lowering motor and propulsion systems
  • Long-term charter improves cost competitiveness of transatlantic feedstock shipments
  • Agreement moves Borealis closer to realizing energy and climate targets in its Base Chemicals business areas and to achieving IINO’s 2050 carbon neutrality realization.

Borealis, one of the world’s leading providers of advanced and sustainable polyolefins solutions, and IINO Kaiun Kaisha, Ltd. (IINO Lines), a global leader in maritime transportation headquartered in Japan, announce the long-term charter of a custom-built vessel, the Oceanus Aurora. The vessel was ordered from IINO Lines in 2021 and delivered to Borealis 14 May 2023.

With a cargo tank capacity of 91,000 m3, largest VLGC (Very Large Gas Carrier) vessel in its class, will transport feedstock – mainly propane and butane – from North America to Borealis crackers and propane dehydrogenation plants in Europe, including Kallo (Belgium), Stenungsund (Sweden), and Porvoo (Finland). As the second long-term charter signed by Borealis, the Oceanus Aurora supplements the charter signed with Navigator Gas for the Navigator Aurora, a dual-fuel MGC (Medium Gas Carrier) which has been transporting ethane to Stenungsund since 2016.

Thanks to its dual-fuel engine, the Oceanus Aurora can be powered by either liquefied petroleum gas (LPG) or low sulphur fuels. The vessel is equipped with a - Shaft Generator Motor system for electrical power generation from LPG dual fuel. This lowers both fuel consumption and emissions, with meaningful reductions in the most common air pollutants from ships, such as nitrogen oxides (NOx), sulphur oxides (SOx), carbon dioxide (CO2), and particulate matter.

The vessel’s environmental footprint is further improved thanks to the installation of an innovative wind propulsion system in the form of two Norsepower Rotorsails™. Developed by Norsepower Ltd., these sails are a modern adaption of the Flettner rotating cylinder and scheduled to be installed within 2nd quarter in 2024. By using modest amounts of electricity to set a deck cylinder in motion, these spinning cylinders, along with the wind, create a Magnus effect to generate thrust. By augmenting the main propulsion system, the sails thus reduce total fuel consumption, emissions, and operating costs.

“It is essential to capitalize on every opportunity to become even more independent and flexible when it comes to transporting cost-competitive feedstock from overseas to our base chemicals operations in Europe,” says Thomas Van De Velde, Borealis Senior Vice President Hydrocarbons & Energy. “As the second long-term charter for Borealis, the Oceanus Aurora is not only giving us the competitive flexibility, but is also helping us reduce the environmental impact of our own transportation operations in accordance with our strategic Energy & Climate ambitions. This is how we continue to re-invent essentials for more sustainable living.”

“At IINO Lines, we use our six decades of experience and know-how in transporting LPG to make shipping more environmentally sustainable,” says Ryuichi Osonoe, IINO Lines Senior Managing Executive Officer Management of Gas Carrier. “We are pleased to have found in Borealis a partner who shares our belief in the power of innovation to reduce environmental impact. This long-term charter is an auspicious start to what we trust will be a long and mutually beneficial partnership.”
