MT-FAST Fuel-saving Device Installed on 500 Vessels

MT-FAST, a fuel-saving device jointly developed by
NYK Group company MTI Co. Ltd. and Tsuneishi Holdings
Corporation, has now been installed on over 500 vessels.
Operational data has proven the device to be effective in saving
fuel.
MT-FAST is a multi-blade device that can be attached to a ship's
hull to improve the propeller's propulsion efficiency.
A ship moves forward when the engine rotates the propeller, which
sucks in the water in front of it and propels that water
backwards, creating the force that pushes the vessel forward.
However, when converting the rotational power into propulsive
power, a swirling flow that reduces propulsion efficiency is
generated.
MT-FAST is attached to a ship's hull just forward of the
propeller and improves the flow of water around the propeller by
reducing the swirling flow generated behind the propeller, thus
improving propulsion efficiency and reducing fuel consumption by
around 4 percent.
MT-FAST can be fitted to new vessels and retroactively fitted to
existing vessels. Since 2008, it has been installed on ships
built at Tsuneishi shipyards and NYK Group operated bulk carriers
and containerships, reaching a 500-vessel milestone and saving
about 447,000 tons of fuel, reducing carbon dioxide (CO2)
emissions by about 1,341,000 tons.
NYK verified the energy-saving effect of MT-FAST at sea using the
company's Ship Information Management System, or SIMS, which
enables the remote distribution and management of onboard
applications from land offices.
In order to grasp the fuel-saving effect, two vessels, one is
equipped with MT-FAST and another without, sailed the same route
in parallel in the same meteorological and oceanic conditions,
and a fuel savings of 4.8 percent was confirmed.
As an organization that conducts business activities globally,
the NYK Group has positioned responses to global environmental
concerns as a significant corporate issue. The company will
continue to promote technological development that will lead to
reduction of environmental load with manufacturers.
In accordance with the new medium-term management plan "Staying
Ahead 2022 with Digitalization and Green" that NYK announced in
March, the company is taking steps to enrich the company's
corporate value by embracing the sustainable development of
society through the creation of new value.
