NYK Line and Japan Marine United Corporation (JMU) have announced plans to introduce a new shipbuilding contract to ensure propulsion performance in actual sea conditions.
Typically, shipbuilding contracts include ship speed with the confirmation of ship speed and horsepower relationship in calm sea conditions, following which mutual confirmation is carried out during the sea trials.
However, many commercial voyages often face stormy weather conditions.
Due to this, shipping companies must acquire ships that feature good propulsion performance in real weather conditions.
With the development of satellite communications at sea and the internet of things (IoT) technology, it is now possible to obtain useful data.
The two companies plan to collect the data necessary for a certain time period after the ship commences services.
They will then verify the data and validate the degree of achievement of the guarantee, which will confirm the ship speed and horsepower relationship in actual sea conditions with wind and waves.
Additionally, NYK Line and JMU are also planning to adopt a PDCA improvement process and collaborate to construct other ship types.
In a statement, NYK Line said: “We plan to further develop this guarantee for verification of propulsion performance for many ship types, which is difficult to do in sea trials at the time of construction.
“We will conduct discussions with our partner shipyards on the performance of vessels in the actual sea conditions and make further improvements.
“By providing customers with well-performing vessels, we will also contribute to improving environmental consciousness throughout the supply chain.”
In July last year, JMU started to build a next-generation energy-saving bulk carrier for NYK.
