Description

本発明は本船から水面上に下降された救命艇を本船に設置されている巻揚げ機により水面から本船上に回収し、本船上に格納するに際し、巻揚げ機から伸長されたロープ先端のサスペンションリンクを、救命艇の船首および船尾に設置された離脱フックに掛止してサスペンションリンクと離脱フックを連結の後、巻揚げ機の作動により救命艇を水面から巻揚げて本船上に回収する方法に係り、特に、多少のうねりの中でも、サスペンションリンクを離脱フックに復旧する作業を容易にし、かつ、救命艇の巻き揚げ中、サスペンションリンクと離脱フックの連結が外れることがなく、例え誤操作により一斉離脱装置が作動しても外れず、救命艇の落下を防止する救命艇の回収方法に関する。   In the present invention, a lifeboat lowered from the ship to the surface of the water is recovered from the surface of the ship by a hoisting machine installed on the ship, and stored on the ship, the suspension at the tip of the rope extended from the hoisting machine. A method of lifting the lifeboat from the water surface and collecting it on the ship by operating the hoisting machine after the link is hooked to the release hooks installed at the bow and stern of the lifeboat and the suspension link and the release hook are connected. In particular, it is easy to restore the suspension link to the release hook, even during slight undulations, and the suspension link and the release hook are not disconnected during the lifeboat hoisting. The present invention relates to a lifeboat recovery method that prevents a lifeboat from falling even if a detachment device is operated.

船舶には本船上に救命艇を搭載することが義務づけられている。そして、これら救命艇は船舶上に搭載するすべての救命艇について、SOLAS国際条約(International Convention for the safety of Life at Sea)第III章第19規則3、3、3の規定により、進水および操船を少なくとも三ケ月に一回実施することが義務づけられている。つまり、最低三ケ月に一回は救命艇を進水し、その後、救命艇を本船に回収する作業を実施しなければならないのである。   Ships are required to carry lifeboats on board. These lifeboats shall be launched and maneuvered in accordance with the provisions of SOLAS International Convention for the Safety of Life at Sea, Chapter III, Rule 19, 3, 3 for all lifeboats on board. Must be carried out at least once every three months. In other words, it is necessary to launch a lifeboat at least once every three months and then carry out the work of collecting the lifeboat on the ship.

しかし、救命艇は一般に退船時に使用することを目的としているため、離脱操作のみが重視され、本船に回収する際の「安全性」や「作業性」が軽んじられているように思われる。   However, lifeboats are generally intended to be used when leaving the ship, so only the detachment operation is emphasized, and it seems that “safety” and “workability” when recovering to the ship are considered light. It is.

事実、救命艇を回収する際の事故(死亡事故を含む)が世界中で多発しており、国際海事機関(IMO:International Maritime Organization)においても、設計設備小委員会(DE:Ship Design and Equipment)の場で当該事故防止のための対策が議論されている。   In fact, there are many accidents (including fatal accidents) when collecting lifeboats around the world, and the International Maritime Organization (IMO) also has a Design Equipment Sub-Committee (DE). ), Measures to prevent the accident are discussed.

本船から海上等の水面上に下降された救命艇を本船に設置されている巻揚げ機により水面から本船上に回収、格納する方法として、従来、巻揚げ機から伸長されたロープ先端のサスペンションリンクを、救命艇の船首および船尾に設置された離脱フックに、乗組員が
救命艇の外に出て手作業で掛止復旧し、サスペンションフックと離脱フックを連結していた。
As a method of collecting and storing a lifeboat lowered from the ship on the surface of the sea such as the sea from the surface of the ship by a hoist installed on the ship, the suspension link at the end of the rope extended from the hoist is conventionally used. The crew went out of the lifeboat and recovered by hand to the release hooks installed at the bow and stern of the lifeboat, and the suspension hook and the release hook were connected.

しかし、このような乗組員の救命艇外での作業は非常に危険であり、特に大きなうねりの中では復旧作業が困難を極める。しかも、従来の方法では乗組員の誤操作や点検整備不良等により、巻き上げ中に解放されるはずのない離脱フックが解放されて救命艇の落下事故を起こす。   However, it is extremely dangerous for the crew members to work outside the lifeboat, and it is extremely difficult to perform restoration work especially in a large swell. In addition, in the conventional method, the release hook that cannot be released during the hoisting is released due to an erroneous operation of the crew or poor maintenance, causing a lifeboat to fall.

回収時に発生している人身事故の多くは救命艇外での作業や、救命艇の巻き揚げ中に離脱フックが解放されて救命艇が落下することで発生している。特に後者の場合は乗組員の誤操作、点検整備不良等により、巻き揚げ中に解放されるはずのない離脱フックが解放されることが原因である。
なし
Many of the personal accidents that occurred during the recovery occurred when the lifeboat was dropped because the release hook was released while the lifeboat was being lifted or when the lifeboat was being rolled up. In the latter case in particular, it is caused by the release of a release hook that should not be released during the hoisting due to the crew's misoperation, poor inspection and maintenance.
None

そこで、本発明が解決しようとする課題は本船の巻揚げ機から伸長されたロープ先端のサスペンションリンクを、救命艇の船首および船尾に設置された離脱フックに掛止して復旧し、サスペンションリンクと離脱フックを連結の後、巻揚げ機の作動により救命艇を水面から巻揚げて本船上の回収するに当り、多少のうねりの中でも、サスペンションリンクを離脱フックに復旧する作業を容易にし、かつ、救命艇の巻き上げ中、サスペンションリンクと離脱フックの連結が外れることがなく、たとえ誤操作により一斉離脱装置が作動しても外れず、救命艇の落下を防止する救命艇の回収方法を提供することにある。   Therefore, the problem to be solved by the present invention is to recover the suspension link at the tip of the rope extended from the ship's hoisting machine by hooking it on the release hooks installed at the bow and stern of the lifeboat. After connecting the release hook, when lifting the lifeboat from the water surface by the operation of the hoisting machine and collecting it on the ship, it is easy to restore the suspension link to the release hook, even in some undulations, and To provide a method for recovering a lifeboat that prevents the lifeboat from falling, even when the lifeboat is rolled up, so that the connection between the suspension link and the release hook does not come off, even if the simultaneous release device is operated by mistake. is there.

上述の課題を解決するため、本発明によれば、水面上の救命艇を本船に設置された巻揚げ機により水面から本船上に回収するに際し、巻揚げ機から伸長したロープ先端のサスペンションリンクを、救命艇の船首尾に設けられた離脱フックに掛止してサスペンションリンクと離脱フックを連結の後、巻揚げ機により救命艇を水面から巻揚げて本船上に回収する方法において、サスペンションリンクを巻揚げ機の操作により救命艇上の近くに下降させるとともに、離脱フックの先端にワイヤを繋ぎ、この繋がれたワイヤをサスペンションリンクに通した後、デッキに穿設された穴に通してワイヤを艇内に引き込み、次いで、艇内でワイヤを緊張してサスペンションリンクを離脱フックに掛止することを特徴とする。   In order to solve the above-described problems, according to the present invention, when a lifeboat on the surface of the water is recovered from the surface of the ship to the ship by a hoist installed on the ship, the suspension link at the tip of the rope extending from the hoist is provided. In the method of lifting the lifeboat from the surface of the water and collecting it on the ship using a hoisting machine, the suspension link is hooked on the release hook provided at the tail of the lifeboat and connected to the suspension link. The hoist is operated to lower it near the lifeboat, and a wire is connected to the tip of the release hook. After passing the connected wire through the suspension link, the wire is passed through the hole drilled in the deck. The suspension link is hooked on the release hook by pulling the boat into the boat and then tensioning the wire in the boat.

本発明はワイヤを離脱フック先端に取りつけ、艇内からこのワイヤを操作することにより、サスペンションリンクを離脱フックに自動的に復旧し、復旧の作業が容易化される。   In the present invention, by attaching the wire to the tip of the release hook and operating this wire from within the boat, the suspension link is automatically restored to the release hook, and the restoration work is facilitated.

さらに、本発明は救命艇の巻き揚げ中、ワイヤを艇内で緊張して固定することにより、サスペンションリンクと離脱フックの連結が外れることがなく、たとえ誤操作により一斉離脱装置が作動しても外れず、救命艇の落下を防止する。   Furthermore, according to the present invention, while the lifeboat is being rolled up, the wire is tensioned and fixed in the boat so that the suspension link and the release hook are not disconnected. The lifeboat is prevented from falling.

以下、本発明を添付図面を用いて具体的に詳述する。   Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

救命艇1は図1に示されるように、本船2に設備された巻揚げ機3のアーム4に懸吊されて本船2内に格納されている。この救命艇1を水面5上に降下させるには、まず、乗組員およびその他客員等がハシゴ9を登って救命艇1に乗り込んだ後、図1に示されるように、アーム5を、支点6を軸にしてストッパー7が本船2の甲板8に接触するまで回動し、救命艇1を本船2外の水面5上に振り出す。   As shown in FIG. 1, the lifeboat 1 is suspended in an arm 4 of a hoisting machine 3 installed in the ship 2 and stored in the ship 2. In order to lower the lifeboat 1 onto the water surface 5, first, a crew member and other passengers climb the ladder 9 and board the lifeboat 1, and then, as shown in FIG. Rotating until the stopper 7 comes into contact with the deck 8 of the ship 2, the lifeboat 1 is swung out on the water surface 5 outside the ship 2.

次いで、図2に示されるように、巻き取り装置10を稼動してロープ11を、滑車12、12・・12を介して伸長し、救命艇1を水面5上に降下する。救命艇1が水面5上に着水後、乗組員はサスペンションリンク13を艇1から離して救命艇1の水面5への降下(進水)が完了する。   Next, as shown in FIG. 2, the winding device 10 is operated to extend the rope 11 through the pulleys 12, 12... 12, and the lifeboat 1 is lowered onto the water surface 5. After the lifeboat 1 has landed on the water surface 5, the crew member releases the suspension link 13 from the boat 1 and the descent (launch) of the lifeboat 1 to the water surface 5 is completed.

さらに、救命艇1を水面5から本船2上に回収格納するには、図3に示されるように、まず、サスペンションリンク13を救命艇1上の近くまで、特に、救命艇1の船首および船尾(いずれも15)に設置された離脱フック16上の近くまで下降させる。図3中、14はハッチ、17は離脱フック16のつめである。   Furthermore, in order to collect and store the lifeboat 1 from the water surface 5 onto the main ship 2, first, as shown in FIG. 3, the suspension link 13 is brought close to the lifeboat 1, especially the bow and stern of the lifeboat 1. (Each 15 is lowered to the vicinity of the disengagement hook 16 installed at 15). In FIG. 3, 14 is a hatch, and 17 is a claw of the release hook 16.

さらに、図4に示されるように、ハッチ14を開けて乗組員が離脱フック16の先端にワイヤ18を繋ぐとともに、図5に示されるように、離脱フック16の先端に繋がれたワイヤ18の先端をサスペンションリンク13に通し、次いで、図6に示されるように、ワイヤ18の先端18aをデッキ19に穿設された穴20に通してワイヤ18を艇1内に引き込む。ワイヤ18は例えば、ポリエチレン系ロープであってもよく、強靭なワイヤであれば材質は問わない。   Further, as shown in FIG. 4, the hatch 14 is opened and the crew member connects the wire 18 to the tip of the release hook 16, and the wire 18 connected to the tip of the release hook 16 as shown in FIG. 5. The tip is passed through the suspension link 13, and then, as shown in FIG. 6, the tip 18 a of the wire 18 is passed through the hole 20 formed in the deck 19 and the wire 18 is drawn into the boat 1. For example, the wire 18 may be a polyethylene rope, and any material can be used as long as it is a strong wire.

さらに、図7、図8、図9、図10に示されるように、ハッチ14を閉じた後、艇1内に引き込まれたワイヤ18を乗組員が艇1内でクリート21に巻きつけて引っ張り、サスペンションリンク13を離脱フック16のつめ17に接触するまで下降させる。このとき、図11に示されるように、サスペンションリンク13はつめ17を押し開いて自動的に離脱フック16に掛止される。ワイヤ18は張った状態でクリート21に巻きつけて固定される。なお、離脱フック16の先端には図12に示されるように、ワイヤ18の繋がれたシャックル22を取り付けることもできる。   Further, as shown in FIGS. 7, 8, 9, and 10, after the hatch 14 is closed, the crew member winds the wire 18 drawn into the boat 1 around the cleat 21 in the boat 1 and pulls it. The suspension link 13 is lowered until it comes into contact with the pawl 17 of the release hook 16. At this time, as shown in FIG. 11, the suspension link 13 pushes and opens the pawl 17 and is automatically hooked on the release hook 16. The wire 18 is wound and fixed around the cleat 21 in a stretched state. As shown in FIG. 12, a shackle 22 connected with a wire 18 can be attached to the tip of the release hook 16.

本発明は離脱フックに繋がれたワイヤを艇内で操作してサスペンションフックを離脱フックに自動的に復旧するため、復旧作業が安全で、かつ容易化され、さらに、ワイヤを艇内で緊張して固定することにより、サスペンションフックと離脱フックの連結が外れることがなく、例え、誤操作により一斉離脱装置が作動しても外れず、救命艇の巻き揚げ中に落下事故が起こらない。   In the present invention, the suspension hook is automatically restored to the release hook by operating the wire connected to the release hook in the boat, so that the restoration work is safe and easy, and the wire is tensioned in the boat. By fixing the suspension hook and the release hook, the connection between the suspension hook and the release hook will not be disengaged. For example, even if the simultaneous release device is operated due to an erroneous operation, it will not come off, and a fall accident will not occur while the lifeboat is being rolled up.

本発明は上述のように、水面上の救命艇をサスペンションフックに復旧し、巻き揚げて本船上に回収格納するに際し、復旧作業が安全かつ容易化されるのみならず、サスペンションフックと離脱フックの連結が外れることがなく、例え、誤操作により一斉離脱装置が作動しても外れず、このため巻き揚げ中の落下事故が起こらず、救命艇を使用する船舶業界において利用可能性が高い。   As described above, when the lifeboat on the surface of the water is restored to the suspension hook, and is recovered and stored on the ship, the present invention not only makes the restoration work safe and easy, but also the suspension hook and the release hook. There is no disconnection, and even if the simultaneous disconnection device is operated due to an erroneous operation, it does not come off, so that it does not cause a fall accident during hoisting, and is highly available in the marine industry using lifeboats.
