GENERAL INSTRUCTION FOR SEA TRIAL 航行试验概述This sea trial is to be executed to ensure the performance of the vessel on the sea. 该航行试验须确保船舶在海水中正常航行。
1.1 Test Condition and Place 试验状态及试验地点 （1）Test Condition 试验状态：Draft @ F.P . / 艏吃水 ＝ mDraft @ A.P . / 艉吃水 ＝ m（2）Place 试验地点：（3）Depth of Water 试验水深： mNote ：(1) Above conditions of official sea trial are to be applied for speed test and maneuvering test. 以上正式航行试验状态适用于航速试验及操纵试验。
(2) Draft measurement should be done by reading the draft mark from a boat before the departure, and compared with draft sensor measurement.吃水测量在试航前从小船上目测吃水位置，并与液位测量仪的结果比较。
(3) Specific gravity and temperature of sea water should be measured before the departure for sea trial. 试航前须测量海水比重及温度。
(4) Displacement of the vessel is to be estimated by hydrostatic table. 船舶排水量从静水力表估算。
1.2 Test Item 试验项目It depends on the following documents and trial schedules. 依据以下文件及试验大纲。
These procedures only describe the hull test as well as its corresponding forms. 该过程仅描述所有船体试验及包含船体试验的记录。
6450DWT OIL PRODUCT/CHEMICAL TANKERSEA TRIAL PROCEDURE VCS565 B2-0401 R03/322. DESCRIPTION OF EACH TRIAL AND TEST 试航试验说明2.1 Progressive Speed Trial 航速试验2.1.1 Test Method 试验方法Time elapsed over the running of 1.0 mile is to be measured by DPGS. The mean speed by MCR is to be calculated.由DPGS记录每一海里的时间，然后计算额定功率时的平均航速。
Note:(1) The trial should be carried out in alternative directions with the same speed for one output of main engine.The speed could not be interrupted during one trial course.测速时每个功率状态须航行两个不同方向，保持速度不能间断。
(2) Main engine revolution could be changed in order to maintain the above horse power. The shaftrevolution should be kept steady before the trial. Throttle and machinery operating conditions could not be adjusted during one trial course. It is permissible to increase the power in order to short the adjustment of lower speed for ship’s turning. The power should be decreased promptly when the ship restores straight running. When a higher speed point is reached, power should be increased before ship’s turning. When a lower speed point is reached, power should be kept until the ship’s turning is completed.为达到每个功率状况，主机转速可以改变。
，但在进入测速时，主机转速须保持稳定，测速时不能停机，主机运行状态不能改变。
但为减小低速调整时，回转时可增加主机功率，但船回到直线时须迅速降低功率。
当增加到高速点时，在回转之前功率可提高；当减小到低速点时，可保持功率直到回转完成。
(3) During the running and speed measurement, the adjustment of the rudder has to be within 3o and itsfrequency has to be minimized.航行及测速期间，舵的调整须小于3o且操舵次数尽可能少。
(4) Main engine speed is to be controlled by governor regulating system.主机速度由主机调速机构控制。
2.1.2 Communication 通信方式ITEM试验项目2.1.3 Test Data 试验数据Under mentioned items are to be measured and recorded. 以下项目需要测量并记录。
(1) Course, weather, sea condition, wind velocity, wind direction and sea depth. 航线、天气、海水状况、风速、风向和水深。
(2) Elapsed time over running one mile to be measured by DPGS system. 每海里航行时间由DPGS 系统记录。
(3) Measurement in Engine room. 机舱测量。
Main engine horse power is measured by torsion meter. Shaft revolution is to be measured by revolution meter mounted on shaft.主机输出功率由主机扭轴表测量。
