Speed and Power Trials

Part I Preparation and Conduct

速度和功率试验

第一部分准备和实施

1.PURPOSE

1.目的

The primary purpose of speed-power trials is to determine ship performance in terms of speed,power and propeller revolutions under prescribed ship conditions, and thereby verifying the satisfactory attainment of the contractually stipulated Ship Speed and to provide the Ship Speed for the calculation of the Energy Efficiency Design Index(EEDI) as required by IMO.

速度动力试验的主要目的是在规定的条件下，以确定船舶性能的速度，功率和螺旋桨转速，从而验证了符合要求的合同规定的航速为能效设计指数计算提供船舶的速度（EEDI）。

The present Recommended Procedure concerns the preparation and execution of speed power trials and has been defined by the 27thITTC Specialist Committee on the Performance of Ships in Service. In this work the Committee took into account:

目前推荐的程序问题关系到速度功率试验的准备和执行，而且在船舶使用性能上已被27thittc专家委员会定义。在这工作中委员会考虑在内的有：

The contracted ship speed and the speed for

EEDI should be determined for stipulated conditions which are defined at specific draughts (contract draught and EEDI draught) and usually for ideal environmental conditions i.e. no wind, no waves, no current, deep water.

合同船舶的速度和EEDI速度应当规定条件下，在特定的吃水深度下定义（合同吃水和EEDI吃水），通常为理想环境条件下，即没有风，没有波澜，没有深水。

Normally, such stipulated conditions are not experienced during the actual trials. In practice,certain corrections for the environmental conditions, as for water depth, wind, waves and deviating ship draught have to be considered. For this purpose not only the Shaft Power and Ship Speed are measured but also relevant ship data and environmental conditions during the speed-power trials.

通常情况下，这样的规定条件在实际试验中没有经验。在实践中，对环境条件的某些修正，如水深、风、浪、船吃水必须考虑。为了这个目的，不仅是轴功率和船舶的速度要进行测量，而且相关的船舶数据和环境条件下的速度功率也要试验。

All trial procedures and measurements should be conducted in such a way that the speed at Contract power and the speed at EEDI Power are derived within 0.1 knots and the Shaft Power within 2%.

所有的试验程序和测量应以这样一种方式，是合同功率和EEDI功率的速度在0.1节以内得到，轴功率在2%以内。
