To meet the requirements of tower turnover and blade docking during wind turbine installation,mobile crawler cranes are usually installed on offshore wind power platforms to cooperate with the lifting work of the main crane.Perform finite element analysis on the crawler crane based on its operating load and motion trajectory.The results indicate that the strength and in-place strength of the lower deck of the crawler crane meet the specification requirements under various operating conditions.The research results can provide some references for the strength calculation,structural optimization,and operation plan of installing crawler cranes on offshore wind power platforms.
In order to reduce emissions and meet environmental emission requirements,based on the liquefied natural gas(LNG)dual fuel power modification project of a 180 000 t bulk carrier in operation,the LNG dual fuel system and the specifications involved in such modification are introduced.The key design points for the modification of the power system,fuel supply system,and gas detection system are analyzed,and the design content of hazardous area division is explained.The research results can provide some references for the electrical design of LNG dual fuel power modification engineering.
近日,美国船级社(ABS)发布了《船舶振动指南》(2023)(简称《指南》). ABS 认为,对船舶整体振动的研究是保证船舶适航性、安全性和功能性的重要措施.《指南》旨在为用户提供设计、分析、测量和标准方面的具体指导,以实现将船舶振动降低到可接受水平的目标.
the construction of safety culture for the first domestic large cruise ship project is carries out.The safety culture model of large cruise ship is constructed based on standards and norms.Seven elements of safety culture construction of large cruise ship are defined,including safety oath,norms and procedure documents,positive safety incentive,safety propaganda platform,award-winning competition and answer of safety knowledge,safety awareness of personnel at all levels and the stationing of safety experts,so as to lay a foundation for the safety of large cruise ship construction.Combined with the actual construction situation,implement various elements of the safety culture model to provide support for the construction safety of large cruise ships.
