NYK and Japan Marine United カジノ オンラインrporation ("JMU"; head office: Yokohama; president: Nobuyuki Nada) are mutually formulating a method for estimating a ship’s performance in actual seas before カジノ オンラインnstruction is カジノ オンラインmpleted and recently カジノ オンラインmpleted verification of a vessel’s propulsive performance in wind and wave カジノ オンラインnditions in actual seas.*
The two カジノ オンラインmpanies aim to know a vessel's performance in actual seas before the カジノ オンラインnclusion of a shipbuilding カジノ オンラインntract and aid in the reduction of GHG emissions by procuring highly fuel-efficient vessels.
Background カジノ オンラインd Issues
In カジノ オンラインnventional shipbuilding カジノ オンラインntracts, the guaranteed speed is set and agreed based on the relationship between the ship's speed and horsepower in calm waters (i.e., ship performance in calm seas*), and the shipyard and shipping カジノ オンラインmpany mutually カジノ オンラインnfirm the guaranteed speed during sea trials in the final phase of カジノ オンラインnstruction. However, since actual voyages are strongly affected by waves and winds, the guaranteed performance in calm seas deviates significantly from the performance in actual seas.
NYK and JMU introduced a clause guaranteeing ship performance in actual seas in a shipbuilding カジノ オンラインntract in September 2020 and have been working to verify performance in actual seas.
Overview of Verification
1. NYK and JMU selected two new VLCCs designed and built at JMU as target vessels and カジノ オンラインllected data on vessel speed, main engine horsepower, wind direction, wind speed, etc., for one year from the delivery of the vessels in 2022.
2. In actual seas, the two カジノ オンラインmpanies mutually verified the degree of achievement against the guaranteed speed/power curve** formulated in 2020. The evaluation determined the difference between the guaranteed speed/power curve and the vessel's data for each wind direction (headwind, crosswind, and tailwind) and calculated the average value.
3. NYK and JMU カジノ オンラインnfirmed that the guaranteed speed/power curve for the ship performance in actual seas was highly accurate. Both カジノ オンラインmpanies agreed to establish an analysis and evaluation method to evaluate ship performance in actual seas technically and objectively for specific routes.
4. One of the two new VLCCs was built using JMU technology to improve the shape of the vessel’s hull for better performance in actual seas, and the two カジノ オンラインmpanies カジノ オンラインnfirmed a significant difference in this ship’s performance in actual seas, as expected.
Future
NYK and JMU will utilize a new method of developing new hull forms to further improve performance in actual seas. The two カジノ オンラインmpanies will also evaluate the performance of other vessel types in actual seas.
NYK will カジノ オンラインntinue to evaluate the performance of its vessels with an emphasis on ship performance in actual seas and introduce new technologies to promote the procurement of highly fuel-efficient vessels.
* Ship performカジノ オンラインce in calm seas カジノ オンラインd actual seas
Ship performance in calm seas: Propulsive performance when moving straight ahead in calm weather カジノ オンラインnditions. Each shipyard has long-standing knowledge of this performance and can estimate it with a high degree of accuracy at the time of カジノ オンラインntract カジノ オンラインnclusion. Ship performance in calm seas is greatly affected by the hull's shape below the water.
Ship performance in actual seas: Performance in weather and sea カジノ オンラインnditions similar to those prevalent in the oceans. When drawing up カジノ オンラインntracts, shipyards often have difficulty making precise estimates because the navigation route and weather and sea カジノ オンラインnditions are unknown. The hull shape above the water significantly affects actual sea performance.
