Mooring wires should be slacked. All the shore connections such as gangways, cables and poses to be lifted clear of the ship. 必须保证在试验过程中，船体自由漂浮，不接触任何其它东西。缆绳呈松弛状态。所有通行跳板、电缆、软管等接岸物件应全部拆除。3. THE PREPARATION AND ORGANIZATION FOR THE TEST试验准备和安排3.1The test should be carried out by Builder, and in the presence of CCSs surveyor and Owners representative. 本试验应由船厂进行，CCS现场验船师和船东代表出席参加。3.2The vessel should be completed all major equipment, fittings and test weight to be placed at each stipulated position, all tools and remainders to be removed from the ship. 试验时应使船上所有的主要设备、装置和试验载荷位于其正确位置，其它的所有工具和残余物均应从船上移去。3.3The foreign and missing weights, vertical and longitudinal positions of centers of gravity to be edited in a table. 多余重量，重心的横向和纵向位置列表。The foreign weights include:Liquids in tanks.Stores, provisions, personnel, etc.Temporary equipment and weights.Moving weights.Any other variable weights. 多余重量包括：液舱内的液体 储藏品，供应品，个人物品等 临时设备和重量 可移动重量 其它可变重量3.4Deck crane, lifeboat and any other equipment which is able to swing or move, to be securely lashed in place. 甲板起重机、救生艇和其它滚动或可移动设备，均应加以固定。3.5Bilge and tank top water should be removed. 舱底和液舱内的水都要打空。3.6Machinery to be in working condition i.e. water and oil in system but all valves to be closed. 使所有的设备都处于工作状态，比如系统内的水和油。但所有的阀门都要关闭好。3.7All water tanks and oil tanks to be emptied, except those which are necessary for adjusting the trim and to be filled up, for example NO.1 B.S.W.

Survey and measure wind direction, wind speed and surrounding condition to ensure that it is complying with the test and mooring condition. 在开始试验前，船体状况应由船东代表和CCS验船师检查，征得他们的同意。需观察测量风向、风速和周围水面的情况，并确认符合试验环境及系泊状态。4. INCLINING TEST 倾斜试验4.1Draft Measurement In order to determine the weight of light ship, the draft measurement to be carried out using a sampan, and the measurement point to be taken at both sides of stem, stern and amidships. Measured drafts at stem and stern should be corrected to drafts at fore and aft perpendicular. The specific gravity of water to be measured. 吃水测量 为了测定空船重量，用小船来测量吃水。测量点分别在船首、船尾和船中各部分的左右舷。 在船首和船尾测得的吃水应修正为在首尾垂线处的吃水。水的密度要测量。4.2 All personnel taking part in the test should be in place, and their weight and gravity centre should be recorded clearly. Excess personnel not directly involved in the test should be away from the ship before the test.参加试验人员应位于规定的位置，记录他们的重量及重心位置，不参加试验的人员均应离船。4.3 The shifting weight for testing are ballast water in NO.3 T.S.W.TK.(P&S). 本试验的移动重量为NO.3顶边压载舱内的压载水。The test steps to be shown in FIGURE 4.试验步序见图4。The height of water surface of each changed ballast tank after each step to be received as accurately as possible by measuring the ullage depth by means of manual sounding. 每一步序完成后应准确地测量各变化压载水舱液面的测深高度。The weight and the distance from center of gravity of each ballast tank to centerline of the ship (TCG) to be got from tank capacity table. 从舱容表可查得目前各变化压载水舱的压载水重量及重心距中心线位置。The next table is showing the weight and TCG of the estimated changed ballast water after each moving step. 下表列出了每一步序完成后各变化压载水舱的压载水重量及重心距中心线估计位置。The maximum heeling angle to the each side of the ship to be estimated as follows:试验时每舷可达到的最大横倾角约为:= arctg Max.
