说说苏伊士多次被堵

sanshandaobojue · 发表于 2021-4-2 09:51

这一次苏伊士被堵的时间比较长，损失严重，吸引了全球媒体。之前苏伊士也多次被堵，只不过时间比较短，有惊无险。收集了一些苏伊士历次被堵的资料。
CHAMPION POMERBLACKOUT IN SUEZ CANALFri Feb 15 19:04:27 CET 2019 Timsen

The "Pomer" suffered am engine blackout, while transiting the Suez Canal in a northbound convoy on Feb 15, 2019, at 7.30 a.m. below the Great Bitter Lake. The tanker which was enroute from Dumai to Taman and had sailed from Suez at 7 a.m., blocked ship traffic in both directions, so that several vessels following the vessel had to wait until tugs moved the "Pomer" to the Great Bitter Lake.

Chemical tanker POMER suffered reportedly, a blackout, while transiting Suez in Northbound Convoy, at around 0730 UTC Feb 15, below Great Bitter Lake. Tanker blocked traffic in both directions, and as of 1300 UTC, traffic still seemed to be blocked. Several vessels following POMER are scattered down the Canal, waiting for POMER to be removed. Several tugs are seen at tanker’s side, POMER is to be moved to Great Bitter Lake. Probably, tanker is aground, though according to track, she isn’t.

Container ship Maersk Shams grounded in Suez CanalThe ultra large container ship Maersk Shams grounded in Suez Canal near the 133 kilometer mark. The vessel was proceeding in southern direction in convoy, but left the fairway and grounded into a sandbank. The ship hampered traffic at the canal and blocked more than 20 vessels from the convoy. At the scene of grounding were dispatched tugs and authorities organized salvage operation. After special survey and underwater inspection, it was estimated the vessel did not suffered any damages and remained seaworthy. The container carrier Maersk Shams was refloated at high tide with assistance of tour tugs. The ship was towed to Suez Anchorage, where was detained for further inspection and special survey. The traffic at Suez Canal was opened after 7 hours of closure and big congestion.

The container carrier Maersk Shams was anchored for further repairs and inspection. The reason for grounding is not yet determined, but according to the local authorities, vessel lost power after blackout. The ship did not suffered serious damages and will return in operations after survey. During the accident there were no injured people and water pollution.

The ultra large container ship Maersk Shams (IMO: 9726669) has overall length of 299.00 m, moulded beam of 48.00 m and maximum draft of 14.30 m. The deadweight of the ship is 111,700 DWT and the gross tonnage is 93,800 GRT. The container ship was built in April 2016 by Huynday Heavy Industries in Ulsan South Korea. The carrier Maersk Shams has capacity for 9,971 TEU.

Al-Muraykh vessel refloated & SUez canal reopened.BSN Correspondent November 27, 202011月26日上午，赫伯罗特（Hapag-Lloyd）旗下一艘超大型集装箱船在苏伊士运河Al Ismailiya附近的交通繁忙水域，在南向穿越运河时，船舶断电主机失去动力。

Al-Muraykh ran aground this morning in the SUez Canal while on Hapag-Lloyd confirmed. However the vessel has now been refloated and the canal has reopened, said a company spokeswoman.

Al-Muraykh was stranded for over five hours and had blocked all traffic on the canal as a consequence. A Hapag-Lloyd spokeswoman told Container News, the vessel “will drop anchor at open anchorage to perform a brief inspection. It has received approval from class, though to continue its voyage. Class inspection will be done in the next port.”

Earlier unconfirmed reports said that movements on the Suez Canal have been blocked following the grounding of the 18,800TEU Al-Muraykh, ex-UASC, now Hapag-Lloyd.

The reports suggest the the 400m long vessel was beached while the vessel was heading south in convoy on the canal, near the 86km mark, close to the TOUSN monitoring station.

Other southbound vessels are stacking up behind Al-Muraykh as a result of the incident.

CMA CGM 9,500 TEU container ship aground, Suez Canal UPDATES Refloated

Oct 16 UPDATE: Singapore, October 16, 2020 – Zeaborn Ship Management, managers of fully cellular containership CMA CGM Missouri, report that last night the vessel was successfully refloated at the Great Bitter Lake in the Suez Canal, Egypt. The ship grounded on Oct 14, whilst under pilotage and in transit in the Canal. There were no injuries to the crew and no pollution occurred as a result of the incident. The Suez Canal remained open for traffic following the grounding and the consequent refloating operation.
The vessel is meanwhile being moved to a safe anchorage at Great Bitter Lake for a survey and underwater inspection. Managers can confirm that the vessel’s hull integrity is intact.
The exact cause of the grounding is yet unknown. A full investigation into the incident will be conducted

Oct 15 1445 UTC UPDATE: Statement regarding CMA CGM Missouri grounding:
Singapore, October 15, 2020 – Zeaborn Ship Management, managers of the container ship CMA CGM Missouri, report that preparations continue for the safe and successful refloating of its vessel at the Great Bitter Lake in the Suez Canal, Egypt. The ship grounded – whilst under pilotage – on October 14 whilst in transit in the Canal. There were no injuries to crew and no pollution has occurred as a result of the incident. Managers confirm the vessel’s hull integrity is intact. Immediately after the incident all relevant parties have been informed.
CMA CGM Missouri is stable with tugs attending and currently awaiting high tide for a next safe, refloating operation. The Suez Canal meanwhile remains open for traffic. The exact cause of the incident is yet unknown. A full investigation into the incident will be conducted.

Oct 15 0315 UTC: Still aground with several tugs working on her. Rumors are the ship suffered a blackout and rudder jam.

Oct 14:
Container ship CMA CGM MISSOURI ran aground in Suez Canal while transiting in southern direction, at around 0930 UTC Oct 14. As of 1745 UTC, probably refloated or moved, several Suez Canal tugs attending. Traffic probably suspended, but it’s not confirmed. No information on what caused grounding.

以上是近年suez发生的船舶black out 后，船舶失控搁浅。
如此频繁发生，证明现有法规规范标准太低了，不能满足suez狭窄航道的通行安全。

偶然的故障不应该导致灾难性的后果。single failure shall not lead to disaster\ essential problem. 船舶设计建造应当有冗余和备份，这是基本原则。开阔海面，船舶失电，舵机失灵45秒是可以接受的。但是狭窄航道，舵机失灵45秒是致命的。
发电机故障，主配点板失电，主机这个时候还是可以正常运行的，没有电，主机可以应急机旁操作啊。并不是说
我的观点是现有关于舵机的法规规范应该有更高的要求，如舵机控制和遥控系统配UPS电池，液压系统配蓄能器。这样即使全船失电，舵机仍然可以正常工作。

我觉得还是运河太窄，对那么大的船来说，只是单船道，扩宽运河变成二船道三船道。

主机的冷却水，滑油泵，燃油等等失电后都挂了

失电以后，主机燃油可以依靠重力油柜，海水冷却没有了，滑油泵停了，滑油温度升高也需要一段时间，主机内部是不是自带滑油泵呢？我记得主机可以机旁应急操作。航行中，主配电板失电，主机继续运行，应急发电机起来之后，至少有一台滑油泵，燃油泵，是有电的。

船体轮机电气，船体永远是老大。我不是船体，我也不是专门研究焊缝的，那是焊接工程师和无损检测探伤专家搞得，你可以说我什么都懂一点，我搞总体的。说到轮机电气，具体细节我肯定不如整天搞轮机电气的，考虑的问题不一样深度不一样角度不一样。我说的也许是错的，如果你不同意你可以指出来，大可不必像个一样纠结于我是谁我是干啥的。但是有一点，你看起来瞧不起船体结构设计和船体验船师，我只能说结构力学和材料力学焊接探伤大有学问。
船在航行中，突然失电会怎么样？我不是研究发动机的，大船小船主机会有什么样的反应？我不是船员没经历过，船厂也没有这样的实验项目，我只能根据设计图纸去想象。小船几千马力的主机燃油滑油有重力油柜，滑油有湿式机带滑油泵，冷却水泵自带，这样主配失电应发起来之前，主机应该还会继续运行吧？大船燃油滑油也有重力油柜，没有滑油循环泵，但是主机自带燃油喷射层泵是？冷却水泵没电，坚持45秒可以么？还是那句话，没做过实验，以前没考虑过失电后主机会怎么样，如果你确切的答案请告诉我。主机遥控坏了可以机旁操作，失电了，本地控制还好用么？我没经验。

我怎么觉得总体布置是老大呢，船体结构归根结底是为了船的功能服务的，船需要什么样的功能，结构就跟着做成什么样。搞结构的人经常说的一句话：总体一根线/结构一大片，其实说的就是结构与总体的大致关系。船舶方案设计前期结构能做的就是从结构强度的角度对总体布置提些意见，比如纵向的平台纵舱壁是否连续等等，

总体人少，不敢自称老大，总体跟船体都是船舶专业出身。我身边人都认为船体是老大，总体倒是经常需要协调解决，船体机电通风电缆管道抢地盘占位置，新船型开发，总布置搞设计还是很有趣的。

不在于人多少，从来都是布置先定，结构再跟进
新船型开发主要都是总体布置稳性和轮机的任务，结构一般就做个中剖面，再就是从结构强度方向跟总布置的舱室分布提提意见，也就这样了

你在说气话，说反话吗？为啥你会这样想呢？不管是船厂的质检还是船东船级社现场验船师，应该是水平很高的，是称职的，要不然凭啥去检查别人的工作？不懂装懂挑不出来毛病的验船师更受船厂欢迎，真正有水平的验船师敢于放水敢于较真提意见，滥竽充数的闭着眼睛签字验收的大有人在。以前验船师都是设计公司和船厂技术部门高手跳槽去做验船师的，现在刚毕业的学生直接去做验船师的确有问题。自己没做过设计凭啥审别人的图纸？没做过设计，凭啥做验船师检查别人？但是你应该相信验船师里有高手，只是你没碰上，碰上了让船厂和设计公司头疼。我曾经是验船师，自我感觉还不错，现在已经不是验船师了，还是怀念那个年代。有部老电影挺不错的，《二十年后再相会》，讲的就是船厂，船级社，船检局，船东之间的爱恨情仇。感兴趣的看一看吧。
还是讨论问题吧，都跑题扯远了。
