NYK Line and Japan Marine United Corporation (JMU) have agreed to introduce a new shipbuilding contract that guarantees propulsion performance under sea conditions that include wind and waves
In light of improvements in satellite communications and IoT technology enabling efficient collection of a variety of useful data at sea, NYK Line and JMU have agreed to introduce an ‘actual sea condition’ clause in a shipbuilding contract.
NYK Line said it expects this performance guarantee will confirm the relationship between ship speed and horsepower under sea conditions that include wind and waves.
In addition to this guarantee, both companies will implement an iterative improvement process and jointly work on the construction of other ship types in the future.
Under the terms of the new contract, NYK Line said the company will collect the necessary data for a period of time after a ship goes into service. The data will be verified and confirm the degree of achievement of the guarantee.
Traditionally, shipbuilding contracts guarantee ship speed by confirming the relationship between ship speed and horsepower in calm sea conditions. The results are confirmed during sea trials which are usually conducted in controlled conditions without excessive winds or waves.
It is generally the obligation of shipping companies to identify and procure ships that have good propulsion performance in actual weather conditions.
But such conditions are rare during commercial voyages.
NYK Line said “We plan to further develop this guarantee for verification of propulsion performance for many ship types [for] which is difficult to do in sea trials at the time of construction.”
The company said it also plans to conduct discussions with partner shipyards on the performance of vessels in actual sea conditions and to make further improvements. NYK Line said this guarantee will aid it in further differentiating itself in ship performance. By providing customers with well-performing vessels, the company is seeking to contribute to improving environmental consciousness throughout the supply chain.
