Abstract:With the global climate getting warmer and warmer, the navigational domain available and its period of time for merchant ships at the Arctic Ocean become more and more extensive. The International Maritime Organization MSC adopted the International Code for ships Operating in Polar Waters (Polar Code) on November 21, 2014. In response to the opening of the Arctic Route, with the help of the experiences sailing at the Arctic, the paper gives special instructions for the Engine Department sailing at this region, including of the crews qualification, the machines operating and maintenances, as well as environmental protection, discussing the other requirements such as steel material, ballasting heating and auxiliary boilers etc. From the view of Engine Department, it also gives some advices for the above concerns in accordance with the case of M/V XueLong, proposing that engineer officers on board ship should actively take measurements to accommodate the opening of the Arctic Water-routes, and to meet the requirements of management and technology | |||

Abstract:How to evaluate time-domain Green function and its gradients efficiently is the key problem to analyze ship hydrodynamics in time domain. Based on the Bessel function, an Ordinary Differential Equation (ODE) was derived for time-domain Green function and its gradients in this paper. A new efficient calculation method based on solving ODE is proposed. It has been demonstrated by the numerical calculation that this method can improve the precision of the time-domain Green function. | |||

Abstract:A technique of dynamic mesh is specially introduced in a 2-D numerical wave tank to simulate the green water incident on a fixed FPSO model in head waves and oscillating vessels in beam sea conditions, respectively. Numerical results agree well with the corresponding experimental ones. It indicates the present numerical scheme and method can be used to actually simulate the phenomenon of green water on deck, and to predict and analyze the impact forces on floating structures due to green water. It is of great significance to further guide the ship design and optimization, especially for ship bow and its strength design. The mechanism may also help seaman to impose operation restrictions to avoid severe green water incidents. | |||
