It is attached. The permeable boarding / exiting floor 36 facilitates passage of seawater such as waves, suppresses deterioration of the follow-up performance of the buoy V smoothly following changes in the sea surface, and reduces the impact of waves.

接舷デッキ部３２Ａ前面に、点検船Ｓの船首部（接舷部）Ｓｔが接舷される接舷用防舷材３８が配置されている。接舷用防舷材３８は、左右両側に配置された側防舷材３８Ｌ，３８Ｒと、中央位置に配置された中防舷材３８Ｃからなり、側防舷材３８Ｌ，３８Ｒおよび中防舷材３８Ｃは、透水状乗降床３６から下方に伸び下端が喫水線の上方近傍に位置し、点検船Ｓの船首部Ｓｔがその中央部分に当接するように構成されている。また中防舷材３８Ｃは透水状乗降床３６が上限となるが、左右の側防舷材３８Ｌ，３８Ｒは、透水状乗降床３６からさらに上方に伸び、設置海域の波浪条件に対応して点検船Ｓの船首部Ｓｔの動揺範囲を越える高さ（たとえば透水状乗降床３６から上下方向にそれぞれ１ｍ、全高が２ｍ）に形成されている。また前記側防舷材３８Ｌ，３８Ｒおよび中防舷材３８Ｃは、前面が円弧状のかまぼこ形断面に形成され、断面中央に長さ方向に沿って円形の貫通穴が形成されている。   On the front surface of the contact deck portion 32A, a contact prevention fender 38 to which the bow portion (contact portion) St of the inspection ship S is contacted is disposed. The armor fenders 38 include side fenders 38L and 38R arranged on the left and right sides, and a medium fender 38C arranged at the center, and the side fenders 38L and 38R and the middle fenders. 38C is configured to extend downward from the permeable boarding floor 36 so that the lower end is located in the vicinity of the upper part of the water line, and the bow St of the inspection ship S abuts on the central part thereof. In addition, the permeable boarding floor 36 has an upper limit for the middle proofing material 38C, but the left and right side proofing materials 38L and 38R extend further upward from the permeable boarding floor 36 and are inspected according to the wave conditions of the installation sea area. It is formed at a height (for example, 1 m in the vertical direction from the permeable boarding floor 36 and the total height is 2 m) exceeding the range of shaking of the bow St of the ship S. Further, the side fenders 38L and 38R and the middle fender 38C have a front surface formed in an arc-shaped kamaboko-shaped cross section, and a circular through hole is formed along the length direction at the center of the cross section.

図１０に示すように、透水状乗降床３６の前縁部には、左右の側防舷材３８Ｌ，３８Ｒがそれぞれ前面に取り付けられたＴ字形断面の左右の側柱材３４Ｌ，３４Ｒと、中央部に配置されて中防舷材３８Ｃが前面に取り付けられたＴ字形断面中柱材３４Ｃとが配置されている。前記左右の側柱材３４Ｌ，３４Ｒおよび中柱材３４Ｃは、浮体１１の外周板１１ａに取り付けられた複数のロッド支持材３５Ａが平面視および側面視でトラス状に連結されて支持されている。さらに左右の側柱材３４Ｌ，３４Ｒの上部と浮体１１の甲板部３１との間に傾斜支持材３５Ｂが連結されて支持されている。これら左右の側柱材３４Ｌ，３４Ｒの上端部には、昇降用把手３４ａがそれぞれ取り付けられ、また左右の側柱材３４Ｌ，３４Ｒ間には開閉用チェーン４０が着脱自在に取り付けられている。さらに左右の側柱材３４Ｌ，３４Ｒの周方向の外側で防衝デッキ部３２Ｂとの境界部に係船柱３７がそれぞれ突設配置されている。   As shown in FIG. 10, at the front edge of the permeable boarding floor 36, left and right side column members 34L, 34R with T-shaped cross-sections attached to the front, respectively, left and right side fenders 38L, 38R, A T-shaped cross-section middle column member 34C, which is disposed at the front portion and has an inner fender 38C attached to the front surface, is disposed. The left and right side column members 34L and 34R and the middle column member 34C are supported by a plurality of rod support members 35A attached to the outer peripheral plate 11a of the floating body 11 connected in a truss shape in a plan view and a side view. Further, an inclined support member 35B is connected and supported between the upper portions of the left and right side column members 34L and 34R and the deck portion 31 of the floating body 11. Lifting handles 34a are respectively attached to the upper ends of the left and right side column members 34L and 34R, and an opening / closing chain 40 is detachably attached between the left and right side column members 34L and 34R. Further, mooring pillars 37 are provided in a projecting manner at the boundary between the left and right side column members 34L and 34R in the circumferential direction and the collision prevention deck portion 32B.

防衝デッキ部３２Ｂは、図１１に示すように、浮体１１の甲板部３１外周の前記内枠材３９ｉと、内枠材３９ｉの外周に一定間隔をあけて配置された円弧状の外縁材４１との間に、エキスパンドメタルからなる網状材が張り付けられて海水が通過可能な作業床（以下、透水状作業床という）４２が水平に取り付けられ、透水状作業床４２とすることにより、波浪などの海水の通過が容易となり、ブイＶが海面の変動にスムーズに追従する追従性能の劣化が抑制され、また波浪の衝撃を軽減させている。また前記外縁材４１は、内枠材３９ｉとの間に連結された水平支持材４３Ａと、外周板１１ａの下方部との間に連結された傾斜支持材４３Ｂとにより、平面視および側面視でトラス状に連結されて支持されている。さらに防衝デッキ部３２Ｂの外縁材４１の外周面に沿って防衝用防舷材４４が取り付けられ、また外縁材４１に沿って安全柵４５が立設配置されている。   As shown in FIG. 11, the anti-impact deck portion 32B includes the inner frame member 39i on the outer periphery of the deck portion 31 of the floating body 11 and an arc-shaped outer edge member 41 arranged at a predetermined interval on the outer periphery of the inner frame member 39i. A work floor (hereinafter referred to as a permeable work floor) 42 through which a net-like material made of expanded metal is attached and allows seawater to pass therethrough is horizontally attached. The passage of seawater becomes easier, the deterioration of the follow-up performance of the buoy V smoothly following the sea surface fluctuation is suppressed, and the impact of waves is reduced. Further, the outer edge member 41 has a horizontal support member 43A connected to the inner frame member 39i and an inclined support member 43B connected to the lower part of the outer peripheral plate 11a in a plan view and a side view. Connected and supported in a truss shape. Further, a fouling-proof fender 44 is attached along the outer peripheral surface of the outer edge member 41 of the shock-proof deck 32B, and a safety fence 45 is erected along the outer edge member 41.

さらに、防衝デッキ部３２Ｂの中間位置で接舷デッキ部３２Ａに対して９０°隔てた位置に、安全柵４５を削除して出入口４７が形成され、出入口４７から垂直梯子４６がそれぞれ垂下されている。４８は出入口４７に着脱自在に取り付けられた開閉チェーンである。   Furthermore, an entrance 47 is formed by removing the safety fence 45 at an intermediate position of the impact-preventing deck 32B and at a position 90 ° away from the contact deck 32A, and the vertical ladder 46 is suspended from the entrance 47, respectively. Yes. An open / close chain 48 is detachably attached to the entrance / exit 47.

次に上記構成の観測用ブイＶに作業員が乗り移る手順を図１３を参照して説明する。
図１３（ａ）に仮想線で示すように、点検船ＳとブイＶとの相対位置の変化を確認しながら、たとえば潮流の下流側から上流側に向かって点検船Ｓを前進させて船首部ＳｔをブイＶに接近させる。この時、ブイＶに設けられた方向制御板１２ｂにより回転方位が保持され、潮流の上流側および下流側に接舷デッキ部３２Ａがそれぞれ位置しているので、点検船Ｓを潮流の上流側または下流側から接近させることで、船首部Ｓｔと接舷デッキ部３２Ａとを容易かつ精度よく接舷することができる。 Next, a procedure for transferring an operator to the observation buoy V having the above configuration will be described with reference to FIG.
As shown by the phantom line in FIG. 13 (a), while confirming the change in the relative position between the inspection ship S and the buoy V, for example, the inspection ship S is advanced from the downstream side to the upstream side of the tidal current, so that the bow portion Bring St closer to buoy V. At this time, the rotation direction is maintained by the direction control plate 12b provided in the buoy V, and the contact deck portions 32A are positioned on the upstream side and the downstream side of the tidal current, respectively. By approaching from the downstream side, the bow portion St and the contacting deck portion 32A can be easily and accurately contacted.

図１３（ａ）（ｂ）に示すように、接舷前または接舷後、点検船Ｓから一対の仮係船索Ｒを左右の係船柱３７にそれぞれ連結し、船首部Ｓｔを接舷デッキ部３２Ａの側防舷材３８Ｌ，３８Ｒおよび中防舷材３８Ｃに当接させた状態で仮係船される。この時、船首部Ｓｔの床部は、接舷デッキ部３２Ａの透水状乗降床３６より下方の接舷用防舷材３８の下部で中間部位に当接されている。そして波浪の状態から船首部Ｓｔの床面が透水状乗降床３６と同位置から少し上位になる時を見計らって開閉チェーン４０を開け、作業員と機材とを透水状乗降床３６から甲板部３１上に移動させる。さらに仮係船索Ｒを係船柱３７から外して点検船Ｓを後退させ、ブイＶから離して待機させる。作業員や機材を撤収する場合には、接舷および乗り移り時と同じ手順で作業すればよい。   As shown in FIGS. 13 (a) and 13 (b), before or after berthing, a pair of temporary mooring lines R are connected to the left and right mooring pillars 37 from the inspection ship S, and the bow part St is connected to the butt deck part. The ship is temporarily moored while being in contact with the 32A side fenders 38L, 38R and the middle fender 38C. At this time, the floor portion of the bow portion St is brought into contact with the intermediate portion at the lower portion of the fendering material 38 below the permeable boarding floor 36 of the fettering deck portion 32A. Then, when the floor surface of the bow St is slightly higher from the same position as the permeable boarding / unloading floor 36 from the state of waves, the opening / closing chain 40 is opened, and workers and equipment are connected from the permeable boarding / unloading floor 36 to the deck 31. Move up. Further, the temporary mooring rope R is removed from the mooring column 37, the inspection ship S is moved backward, and it is separated from the buoy V and waits. When removing workers and equipment, work in the same way as when contacting and transferring.

点検船ＳのブイＶへの接舷は、波浪が安定した時期のみに実施されるわけではなく、荒天状態の場合にも多くメンテナンスを必要とする。荒天状態では点検船ＳおよびブイＶが大きく動揺し、図１３（ｃ）に示すように、波の谷部では、船首部Ｓｔの当接位置が側防舷材３８Ｌ，３８Ｒおよび中防舷材３８Ｃの下端部まで下がり、また波の山部では、図１３（ｄ）に示すように、船首部Ｓｔの当接位置が側防舷材３８Ｌ，３８Ｒの透水状乗降床３６より上位に上がる。このように波の山部では、従来では、船首部Ｓｔが浮体１１の甲板部３１に乗り上げてしまうおそれがあったが、本発明では、接舷デッキ部３２Ａの左右両側に配置された側防舷材３８Ｌ，３８Ｒが、透水状乗降床３６から上方に十分な高さを持って立設されることから、船首部Ｓｔが透水状乗降床３６側に迫り出して浮体１１の甲板部３１にまで乗り上げるのを確実に防止することができ、これにより作業員の安全を確保することができる。   The inspection ship S is not only engaged with the buoy V when the waves are stable, and requires a lot of maintenance even in a stormy state. In the stormy weather, the inspection ship S and the buoy V are greatly shaken, and as shown in FIG. 13C, the contact position of the bow St is the side fenders 38L and 38R and the middle fenders at the wave valley. As shown in FIG. 13 (d), the abutting position of the bow St rises above the permeable boarding floor 36 of the side fenders 38L and 38R. As described above, in the hills of the waves, conventionally, there is a risk that the bow portion St may ride on the deck portion 31 of the floating body 11, but in the present invention, the side guards disposed on the left and right sides of the contact deck portion 32A. Since the anchors 38L and 38R are erected with a sufficient height above the permeable boarding floor 36, the bow portion St protrudes toward the permeable boarding floor 36 side and reaches the deck portion 31 of the floating body 11. It is possible to reliably prevent the vehicle from climbing up, thereby ensuring the safety of the worker.
