The bulker segment is making significant strides in adopting
wind-assisted propulsion technology, with Mitsui O.S.K. Lines and Brazilian
mining giant Vale recently achieving a milestone by retrofitting rotor sails to
a Capesize bulker. The vessel in question, the Camellia Dream, is a 206,800 dwt
bulker built in Japan and delivered a decade ago. It has been retrofitted with
two rotor sails manufactured by Norse power, each standing approximately 115
feet (35 meters) tall with a diameter of 16.5 feet (5 meters). This retrofit
marks a noteworthy advancement in the deployment of wind-assisted propulsion,
extending its use to Capesize bulkers, which are among the largest cargo ships.
The Camellia Dream, registered in Japan, embarked on its first voyage following
the retrofit from Ponta da Madeira, Brazil, on August 17. It had previously
travelled from the Far East and arrived in South America in mid-August. This
vessel typically transports iron ore for Vale under a midterm contract with
Mitsui O.S.K. Lines, following its regular route. The rotor sails are expected
to contribute to approximately 6 to 10 percent reductions in fuel consumption
and greenhouse gas (GHG) emissions. This improvement is achieved through a
combination of the rotor sails and advanced voyage optimization technology
designed to maximize efficiency. This retrofit is part of Vale's broader
strategy to reduce its Scope 3 emissions by 15 percent by 20235, a goal that
encompasses the emissions associated with its entire value chain, including shipping.
Although Vale does not own the vessels, it includes these reductions in its
overall supply chain emissions calculations.
