速度和功率试验的主要目的是确定船舶在规定船舶条件下的速度、功率和传动轴速度性能，从而验证船舶是否达到EEDI法规和/或合同规定的速度。 ISO 15016:2015定义并规定了在船舶速度试验的准备、执行、分析和报告中应用的以下程序，以及可能影响速度、功率和传动轴速度关系的影响: ·各方的责任， ·审判准备工作， ·船的状况， ·有限的天气和海况， ·审判程序， ·审判的执行， ·所需的测量， ·数据采集和记录， ·评估和纠正的程序， ·结果的处理。 合同规定的船速和EEDI的船速根据规定的条件和特定吃水（合同吃水和/或EEDI吃水）确定。对于EEDI，环境条件为:无风、无浪、无海流和15°C的深水。 通常情况下，在实际审判中，不太可能部分或全部经历这种规定的条件。在实践中，必须考虑对环境条件的某些修正，例如水深、表面风、波浪、海流和偏离的船舶吃水。 为此，在速度和功率试验期间，不仅要测量轴功率和船速，还要测量相关的船舶数据和环境条件。 ISO 15016:2015的适用范围仅限于排水型船舶。

The primary purpose of speed and power trials is to determine a ship's performance in terms of ship's speed, power and propeller shaft speed under prescribed ship's conditions and thereby verify the satisfactory attainment of a ship's speed stipulated by EEDI regulations and/or contract. ISO 15016:2015 defines and specifies the following procedures to be applied in the preparation, execution, analysis and reporting of speed trials for ships, with reference to the effects which may have an influence upon the speed, power and propeller shaft speed relationship: · the responsibility of each party involved, · the trial preparations, · the ship's condition, · the limiting weather and sea conditions, · the trial procedure, · the execution of the trial, · the measurements required, · the data acquisition and recording, · the procedures for the evaluation and correction, · the processing of the results. The contracted ship's speed and the ship's speed for EEDI are determined for stipulated conditions and at specific draughts (contract draught and/or EEDI draught). For EEDI, the environmental conditions are: no wind, no waves, no current and deep water of 15°C. Normally, such stipulated conditions are unlikely to be experienced in part or in full during the actual trials. In practice, certain corrections for the environmental conditions such as water depth, surface wind, waves, current and deviating ship draught, have to be considered. For this purpose, during the speed and power trials, not only are shaft power and ship's speed measured, but also relevant ship data and environmental conditions. The applicability of ISO 15016:2015 is limited to ships of the displacement type.
