摘要
EEDI(能效设计指数)生效后,为避免装机功率过低,船舶在恶劣海况中失去操纵性而发生危险,IMO(国际海事组织)在第65届环保会(MEPC65)发布了"船舶在恶劣海况下维持操纵性的最小推进功率确定临时导则(2013)"。临时导则分为最小功率线方法和简化评估方法对主机功率进行评估。最小功率线评估方法的核心是考核主机在最大转速下可发出的最大功率,参考线通过统计资料回归得到。简化评估方法的核心是船舶在指定的海况条件下,达到规范要求的前进速度,考核主机是否可以发出船舶需要的功率和扭矩。结合一艘散货船的设计案例,研究了导则对主机功率点选取的影响。
After theEEDI （energy efficiency design indicator） entered into force, IMO （International Maritime Organization） approved the＂Interim Guidelines for determining minimum propulsion power to maintain the maneuverability of ships in adverse conditions＂ in the 65th Marine Environment Protection Conference （MEPC 65） in order to avoid the danger of ship losing maneuverability in harsh environmental conditions due to insufficient engine power. The interim guidelines evaluate the main engine power according to the minimum power lines method and the simplified assessment method. The core of minimum power lines method is to evaluate the maximum power of the main engine under maximum revolution, with the reference lines obtained from regression of statistical data. The core of the simplified assessment method is to evaluate whether the main engine can deliver the required power and torque under the given sea conditions and forward speed. Taking a bulk carrier as the design example, the influence of interim guidelines on main engine power selection is studied.
