<p>With the&nbsp;increasing popularity of environmental awareness, the shipping industry has generally noted the issue of protecting the atmosphere. EEDI embodies the energy efficiency index of the new ship, and&nbsp;the minimum propulsion power ensures the safety of the ship. So the contradiction between EEDI and the minimum propulsion power of the ship is essentially the one&nbsp;between energy saving and safety. How to realize the integrated&nbsp;optimization of the two is the focus of this&nbsp;paper&nbsp;.&nbsp;An integrated optimization model of EEDI and minimum propulsion power&nbsp;has been established in this paper. EEDI optimization needs to meet IMO requirements for minimum propulsion power. In order to coordinate the contradiction between the reduction of EEDI and the minimum propulsion power of the ship, this paper is devoted to the development of an effective and efficient EEDI optimization method under the minimum propulsion power constraints of the ship. The evaluation method of the objective function EEDI is a digital pattern of hydrodynamics performance for tanker series&nbsp;developed by the China Ship Science Research Center. In order to illustrate the method, the VLCC is selected as the research object, and optimization algorithms are selected. The calculation results show that the EEDI and minimum propulsion power integrated&nbsp;optimization model are reasonable and effective.</p>

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
