1、1.4. 计算时充分注意自由液面、油水消耗、污水变化和压载水变动等对船舶稳性产生的影响,确保船舶在离港、航行、抵港的过程中均满足要求。开航前,大副应完成初稳性高度的计算,并将稳性计算中的重要内容摘录记在船舶稳性计算记录摘要中,报船长审核确认签字后方可开航。When calculating, pay sufficient attention to the influence of free liquid surface、consumption of bunker、change of drainage and variation of ballast water to the ship stabi
2、lity, make sure ship meet requirements when departure、sailing、arrival. Before sailing chief officer should finish calculating GM, and record important content into ship stability calculation record summary, after verified by captain, start sailing.1.5. 船舶在航行中,值班驾驶员应经常测定船体的摇摆周期,核算初稳性高度值,一旦出现摇摆周期超长或摇摆
3、复原过缓等稳性不良状态时,船长应迅速采取改善性的各种有效措施,确保航行安全。During sailing, the officer on duty should often measure swing cycle of the ship, calculate GM, once appear harmful status such as swing cycle is too long or swing recover is too slow, captain should immediately take all kinds of actions to improve the situation
4、, make sure safety sailing.2. 船舶下潜操作规程Ship Diving Operation Procedure2.1. 下潜准备工作:Diving Preparation:2.1.1. 确保舱底机舱逃生舱门水密,保持与机舱通信联系畅通。Make sure the bottom escape door is watertight and keep correspondence with engine room unblocked.2.1.2. 叉车移走放在E层甲板或车间内。Move the forklift onto E deck or into the worksh
5、op.2.1.3. 存放在舱内的漂浮垫舱料若未移出必须使用货网或绳索固定。If the floating dunnage which was stored in the hold wasnt moved out, it must be fixed by cargo net or rope.2.1.4. 下潜水位达舱灯位置(约6米)时,从舱灯到左右通道的开口必须封牢。When the diving level reaches the hold light (about 6metres), the hole from hold light to both sides passageway must
6、 be sealed.2.1.5. 舱内松散设备如浮箱、滑梁等必须打开人孔。The loose equipments such as buoyancy tank and slide bridge must be open manhole.2.2. 下潜工作Diving Operation:2.2.1. 下潜操作应保持尾倾约1米。During the diving operation, keep down by stern about 1metre.2.2.2. 压载操作:Ballast Operation :2.2.2.1. 预先压载使船吃水达到7米,使用边舱NO.23、24、29、30、31
7、、32和底舱NO.15、13、14、19、20压载,越靠近压载泵的舱室压水越快。Ballast in advance to make sure the draft reaches 7metres, and utilize the wing tank NO.23、24、29、30、31、32 and bottom tank NO.15、13、14、19、20 to ballast, the closer to the ballast pump, the more quickly ballast.2.2.2.2. 检查尾门底板(受水压底板可能竖起来)。Check the stern door ba
8、seboard (it maybe stand up under the water stress).2.2.2.3. 打开尾门前不必让底部高出水面7米,但也不能让底部超过水下50CM。只有水深达到30CM打开尾门。Dont let the bottom above the water 7metres before opening the stern door, but also dont let the bottom beyond underwater 50CM. Only when the depth of water reaches 30CM, open the stern door.2
9、.2.2.4. 使用NO.21、22、5、6舱等监控吃水差。Utilize the tank NO.21、22、5、6 to monitor trim.2.2.2.5. 当水漫过机舱逃生孔及下潜过程中尤其应注意舱内水的变化。When the water over the engine room escape door, especially notice the change of water level in the hold during diving.2.2.2.6. 记住下潜时TPC会减少很多。Remember during the diving, TPC will reduce a
10、lot.2.2.3. 下潜装卸货期间:Diving Cargo Handling:2.2.3.1. 下潜等货状态保持尾门开到约50CM间隙,减少舱内涌浪冲击影响。When the ship is in the state of diving waiting cargo, keep the stern door open to about 50CM interval, and reduce the impact of swell.2.2.3.2. 操作装卸货物时注意不要碰损外伸导轨和三脚架。Do not damage protract slide bridge and tripod during
11、 handling cargo.2.2.3.3. 上浮时应保持同下潜时一样吃水差。When the ship comes-up, keep the same trim as diving.2.2.3.4. 保持与机舱通信联系畅通。Keep correspondence with engine room unblocked.2.2.4. 过大桥限高超压载操作类同下潜操作。Cross the bridge limit superb ballast operation similar to descend operation.3. 船舶稳性计算 Ship Stability CalculationG
