"If the shipping industry is to achieve IMO's target of full decarbonization by 2050, now is not the time to stand still."
— CEO Heikki Pöntynen
As the shipping industry faces increasingly stringent decarbonization
targets and environmental regulations, stakeholders are accelerating
efforts to reduce emissions. However, uncertainties surrounding
alternative fuels pose significant challenges. Against this backdrop,
green technology has become an efficient way to reduce emissions in the
industry, and rotor sails have emerged as one of the most effective
solutions.
During the opening ceremony of
Norsepower's new factory, Xinde Marine News conducted an exclusive interview with
Heikki Pöntynen,
CEO of Norsepower, the leading company in rotor sail products. In the
interview, Heikki shared his insights on decarbonization pathways, the
current application of rotor sails, and the market outlook, offering
valuable perspectives for our readers.
New Factory in China: 100 Sails Per Year
Founded in 2012, Norsepower is a pioneering company specializing in
wind-assisted propulsion systems. The term "rotor sail" coined by
Norsepower, has become widely used in the industry.
According to Heikki, Norsepower is experiencing rapid growth across
various fronts, including workforce, revenue, and company deliveries. To
support this growth, the company opened its first dedicated rotor sail
factory in Jiangsu, China, in November 2024. This factory marks a
significant leap forward in increasing Norsepower's production capacity
for its Norsepower Rotor Sails™ (NPRS).
"This dedicated factory enables us to advance product research and
development and deliver the most optimal solutions to the market,"
Heikki noted. The factory's planned capacity is one rotor sail per week,
totaling 50 sails per year, with the potential to expand to 100 sails
annually based on market demand.
Four Key Advantages
When discussing operational performance, Heikki stated: "As you can see
from the market, there are different types of solutions for
wind-assisted propulsion systems. But this is a very particular product
that we have. To put it simply, it's actually the most efficient
solution."
The rotor sail greatest advantage is its ability to significantly
reduce emissions. The thrust generated by the spinning sail accelerates
the ship's speed. Heikki explained: "For example, we have a midsize
tanker sailing at eight knots using sails alone, with the main engine
completely shut down." The Norsepower Rotor Sail™ can harness wind from
various directions, reducing fuel consumption and CO₂ emissions by
5–25%, with even higher savings under favourable conditions. In headwind
situations, crews can adjust the course to maximise performance.
Another advantage is its simplicity of operation. Heikki highlighted:
"Crews just need to plan the route and press a start button. The system
handles the rest." Combined with route optimization, the NPRS ensures
maximum efficiency with minimal intervention.
The technology is also highly versatile, suitable for a wide range of
vessels such as bulk carriers, tankers, ferries, and LNG carriers. An
optional "tiltable foundation" allows the sail to be lowered for
height-restricted routes.
Addressing downtime concerns, Heikki noted: "The standard installation
time is two weeks per sail, usually during dry-docking." According to
Heikki, if dry-docking is not planned, the foundation can be prepared in
advance, and the sails installed and commissioned within a week. This
minimizes disruptions and boosts the vessel's market competitiveness.

Decarbonisation Beyond Compliance
Rotor sails align closely with global trends in sustainability and
green development. Heikki emphasised: "If the shipping industry is to
achieve IMO's target of full decarbonization by 2050, now is not the
time to stand still." He noted that green shipping is no longer limited
to mere compliance.
On one hand, while regulations remain a key driver, achieving up to 30%
carbon reduction cannot rely solely on biofuels—additional solutions
are essential. Rotor sails are perfectly suited for this purpose and
play a pivotal role in transitioning the global shipping industry
towards sustainability.
On the other hand, market forces and consumer values are evolving.
Customers, businesses, and even end-users are increasingly prioritizing
green values. For instance, growing attention to the concept of "green
corridors" reflects this shift. "If you buy chocolate in Finland, some
younger people may ask, has this ride to Finland been through the green
corridor? Or is it just a polluted product?" Heikki observed. This
clearly reflects the market's urgent need for green development.

Retrofitting and Long-Term Returns
Heikki believes rotor sails are not just a green shipping solution but
also a game-changer for the retrofitting market, especially for older
ships with poor fuel efficiency and high emissions.
"The global fleet is enormous, and many older vessels, especially those
over 20 years old, remain in operation with bad fuel economy."
Retrofitting these ships with rotor sails can improve fuel efficiency
and reduce emissions, aligning with decarbonization and environmental
goals. Additionally, this technology can extend the operational lifespan
of vessels, generating greater economic value for shipowners.
The current market interest in rotor sails is substantial. Heikki said:
"When meeting with shipowners or companies, I no longer need to explain
the physics behind the technology. Everyone already understands its
purpose and value. I believe the industry is responding very actively.
On average, we receive one inquiry per day regarding newbuilding
projects. The market is highly aware of these technologies, and everyone
is searching for the best solution."
Norsepower highlights the strong economic return of rotor sails. Heikki
stated: "Norsepower Rotor Sails offer the best return in euros per
kilowatt produced over their lifetime. This is a crucial factor—while
other sails or solutions may perform well on certain voyages, over the
lifetime, this is a more efficient solution."
A Familiar Partner in China
Heikki shared his deep connection to China during the interview: "I'm
very familiar with China, having lived here for six years. I've
collaborated with CSSC and COSCO to establish joint ventures in the
past. I like this country and the way they work and do business. So it's
really a pleasure to be back doing business here."
He continued: "We are actively cooperating with China. Our cooperation
with local governments has been smooth, and the authorities have been
really supportive. For example, our new factory is located near key
regions like Nantong and Nanjing along the Yangtze River, which are
vital hubs for shipbuilding and retrofitting activities."
Steady Growth Ahead
To date, Norsepower has installed approximately 30 rotor sails on 17
vessels. Over the next 18 months, this number is expected to double,
exceeding 30 vessels equipped with the technology.
Heikki expressed optimism: "Obviously, the market demand is huge, and
we are now really in the number one position. We have been the first
mover in the market, and now we have established ourselves with a proven
product."
"We have solid research and development activity in the company, making
sure we have full intelligence around the entire product – when it
comes to the controls, manufacturing, lifecycle, and performance. At
this point, our patent IPR protection includes a patent family of about
70 patents, with 20 more pending. We are trying to be very secure in our
position."
"Our strategy for the coming years is to double our delivery scale
annually—for instance, from 20 ships this year to 40 next year, then 80
the year after. We aim to achieve steady and robust growth."
The shipping industry, after centuries of evolution, has come a
circle—from traditional sails to modern technologies like rotor sails.
Just like Heikki said: "The wind is our friend." Norsepower will
continue to embrace the power of wind and nature, steering the shipping
industry towards a greener future.
