    全球目光的焦點: 長範輪明天(8/28)01:00過蘇伊士運河

    長範輪: It’s carrying capacity is 23992 TEU and her current draught is reported to be 16 meters. Her length overall (LOA) is 399.9 meters and her width is 61.53 meters.

    與長賜輪之比較:
    船舶內部的硬體:一樣長,更寬61.53/59,更深16/15.7(船底UKC更少),較長賜輪可多裝2604TEU.再加上船艏部份為了創紀錄而在第一BAY更寬而造成的”寬楦”,在在都使得長範輪水下部分之”方塊係數(Block coefficient)較長賜輪更形”豐滿”,相對的也更難操縱!

    外部過運河的環境:沒有改變與改進,希望沒有沙塵暴

    1. 像這種全球最大型貨櫃船要過運河,或是進出港口,依照台灣引水組織的慣例,都是由各港引水公會挑選資深領港,或由公會主任親自引領(這樣才不會像長賜輪兩位運河領港在駕駛台上發生”意見不合”而爭吵的現象);
    2. 要知道長範輪的海試(Sea Trial)是在寬廣的深水區中進行,實際上在航道,港口,尤其是運河中的操縱性,會因為當時當地的吃水/水深比,船寬/航道寬之比例不同而會有不同之反應,全賴領港之臨場反應.
    3. 針對”長賜輪”因指向性不穩定,而採取”加俥加舵”至使得船速有13節而發生淺水效應,岸吸+岸推效應遽增的惡性循環,終至觸岸擱淺.要基於學理與經驗,預先防範,(寧可信其有),

    在關鍵性環節(指向性不穩定)沒有針對性的解決方案之前,一切交給阿拉!
    人類的勇敢再次挑戰物理性的極限,讓我們集氣共同祝福長範順利過河.

    長賜輪在蘇伊士運河擱淺後,綜合外電報導的省思:極限邊緣的船舶操縱,科學與安全之間給”人的反應”留下多少”餘裕空間?

    航行員都知道:在有限水域中的船舶操縱與大洋中的船舶操縱有極大的差別,也因此而產生一些”異常反應”的專有名詞,譬如:淺水效應,岸吸/岸推,船體下坐(Squat),狗頭嗅地(Dog smelling),單俥右旋船在淺水區倒俥時之船頭可能向左,主要的原因都是來自船舶四周的海水,來不及湧入去填補船艉所造成之空穴.

    也因為這個緣故,Suez Canal當局對過河船隻有一些船寬,吃水,速度上的限制.基於經濟上的考慮,可以想像這些限制都是在”水工模型”下最大化的尺度界線.(越大的船過河費越貴),然而這些都是理想環境下的科學論證,實際上船舶操縱者的精神狀態,駕駛台的氣氛環境,外界視線,無線電之干擾,Marlboro菸未如預期,住艙走廊上”波斯市場”的氛圍….都在影響著”駕駛台資源管理(BRM)”,而使得船舶之實際Performance遊走在”紅線”邊緣,更糟的是一但越過紅線(Point of non-return),情況就越來越糟,猶如在山脊上騎腳踏車.

    這次的重大意外,在檢討”船舶因素”之外,蘇伊士運河當局也應該重新考慮”紅線邊緣的緩衝區”是否應適度放寬,以因應船舶無止境的大型化,因應極端氣候下的異常天氣,因應新世代船員之特性,另外也可考慮在駕駛台放一箱Marlboro,讓有需要的人看自己包包大小量力自取,畢竟比起全球供應鏈上的損失,這都是微不足道的”潤滑油”.不是嗎?

    The Suez Canal Authority occasionally brings out updated tables of width and acceptable draft for ships. Currently the permissible limits for suezmax ships are 20.1 m (66 ft) of draught with the beam no wider than 50 m (164.0 ft), or 12.2 m (40 ft) of draught with maximum allowed beam of 77.5 m (254 ft). Due to their design and size, a large number of ports around the world can accommodate suezmax vessels.
    17,65 56,96
    , a new set is being built for vessels as large as 366 meters in length, 49 meters in beam and 15.2 meters in draft at tropical frvessel.
    That would have surpassed the speed limit of about 7.6 knots (8.7 miles an hour) to 8.6 knots that is listed as the maximum speed vessels are “allowed to transit” through the canal, according to the Suez authority’s rules of navigation handbook posted on its website. Captains interviewed for this story said it can pay to increase the speed in the face of a strong wind to maneuver the ship better.
    “Speeding up to a certain point is effective,” said Chris Gillard, who was captain of a 300-meter container ship that crossed the Suez monthly for nearly a decade until 2019. “More than that and it becomes counter effective because the bow will get sucked down deep into the water. Then, adding too much power does nothing but exacerbate the problem.”
    “You might find yourself positioning the ship in one direction, and you’re actually moving in another direction,” said Kinsey. “There’s a very fine line between having enough speed to maneuver and not having too much speed that the air and hydrodynamics become unstable. Any deviation can get real bad real quick because it’s so tight.”

    The accident will be a missed opportunity if the industry doesn’t adapt, he said. “There will be vessels larger than this one that will be going through the Suez,” he said. “The next incident will be worse.”

    • The Ever Given's speed was 13.5 knots before it ran aground, The Japan Times reported.
    •
    • Bloomberg reported the Suez Canal speed limit was between 7.6 knots and 8.6 knots.
    The Ever Given didn't have a tugboat escort through the canal, according to Bloomberg. The two ships immediately ahead of it reportedly had escorts, although such escorts were not required.

    才剛花了六個小時開車進入南非，一到營地馬上就換上泳衣划船去👙 Orange River 是南非與納米比亞的天然邊界，不過寬度窄到如果要游泳跨國絕對沒問題🏊 七月的河水超級冷，每划一次槳就打在腿上，讓人起雞皮疙瘩...😨 沒想到居然一次要划七公里才能回到營地！兩個小時我們全部的人不停的划，當晚幾位年紀年長的人就開始腰痛...😰

    我本來很偷懶都讓 York一個人使力，但後來看到太陽快下山🌅 昨天因為營地沒熱水所以沒洗，如果今天又搶不到熱水洗澡我一定會瘋掉！於是最後一公里我超級努力地划💪 當時我真的是超有毅力，嘴裡一直念著“我要熱水澡”😝 話說外國人的划船怎麼不悠哉... 七公里很累欸...😰 #南非 #戶外活動 #八女四男搶熱水戰

    Just spent six hours bus ride into South Africa, as soon as we hit the campsite it's off to canoeing time🚣 Orange River is the nature boarder between Namibia and South Africa, but parts of the river were so narrow people can just easily swim across🏊 I couldn't believe that we had to canoe 7 kilometers back to the campsite⛺️ All I had in mind was that I had to make it to the hot showers before anyone else💪 Due to the recent draught the water was quite calm, made it a nice scenic ride...
