| 摘要： | In order to develop ships for more efficient transport at sea, with reduced specific fuel consumption and emissions, the tendency is to design larger ships. There is a big potential to develop ships for more efficient transport at sea by optimizing the construction to reduce weight and steel and lower the cost for building and operating the ship. In this process it is of first importance to ensure that any changes in the construction is done in a secure way. The effect of less steel and changed construction in the ships damage tolerance against wind and wave loads, and the dynamic response of those external forces, has to be evaluated. According to a study from IMO 2009 the potential is a 2-20 percent reduction in greenhouse gases for an optimized hull construction and reduced weight. To ensure that legislation is followed with respect to structural strength, seakeeping characteristics, environmental requirements and safety at sea more knowledge is required to understand how requirements and solutions affect the complex construction of the ship. Today there is a lack of guidelines and regulations which accounts for the dynamic loads on the ship when it is operating in wind and waves. Studies report that ships of different types have increased problem due to wave loads leading to resonance (springing) or fading vibrations (whipping) in the hull beam. This has led to ships that have cracked and constructions have broken due to a combination of fatigue and exceedance of global longitudinal strength. A lack of basic understanding may lead to the opposite effect, i.e. ships are designed to be oversized leading to higher weight and larger displacement, leading to unnecessarily high fuel consumption and increased environmental impact. The project aims to conduct joint research and development of refined methods for dynamic design of ships, to increase the knowledge about how dynamic loads on ships affects the structural response. |
