Operation
[0075] In one exemplary embodiment, as shown in
[0076] In another exemplary embodiment, as shown in
[0077] The wing rotation actuators, may be controlled locally with controls located at the actuator, and/or with at least one remotely-located control panel located anywhere on the deck of barge 100 or in the wheel house or control room of barge 100.
[0078] Alternatively, in yet another exemplary embodiment, each wing may be urged directly by cables. The cables may be rope or steel cable or any other type of cable that has sufficient strength, flexibility, and durability for this purpose in a marine environment. In this example, at least one cable would pull each wing into the deployed position and while at least one other cable would pull in the opposite direction such that sufficient tension is maintained in all cables to maintain the position of each wing. Leverage may be required at the pivot, for example, in order to have sufficient leverage for the cable to react against. Each cable may be manipulated by hand by deck hands, and/or assisted with at least one tensioning device such as a power wench, windlass, or capstan, for example.
[0079] With at least one wing deployed as shown in
[0080] Each wing of barge 100 exists in one of two general modes of operation: a) deployed (wings positioned away from main section 102 as shown in the example of
[0081] The operational flexibility of barge 100 provides many configuration options that may be used depending on the circumstances that are encountered: [0082] a) As one of many examples, as shown in
[0091] Once barge 100 and vessel 200 are oriented next to each other in one of the configurations described above, for example, then the two watercrafts may be coupled together for the duration of the operations. Some examples follow: [0092] a) In one exemplary embodiment, the most common method is to couple with lines, which are cables or ropes commonly used for this purpose. Lines or ropes are used in combination with the usual cleats, chocks, bits, bollards, etc. so that the lines are in the proper orientation to substantially limit relative movement between the two watercrafts. Barge 100 has sufficient hardware (cleats, chocks, bits, bollards, etc.) located throughout main section 102 and each wing. The lines are typically pulled tight with sufficient tension manually and/or with the aid of a power windlass, power winch, power capstan, or similar. [0093] b) In another exemplary embodiment, as shown in
[0094] Fenders are used to create a soft interface between barge 100 and vessel 200. Fenders are required in each location where contact between barge 100 and vessel 200 is anticipated. Thus, fenders may line some or all of the outer edges of main section 102 and wing 110 and wing 120. The fendering system must a) maintain a suitable distance between barge 100 and vessel 200, b) provide a soft interface to prevent damage to painted metal surface of either watercraft, c) be durable enough to absorb the constant relative motion between the watercraft, and d) absorb the constant impact from the frequent shocks caused by relative motion between the watercraft, waves, swells, and/or wakes from other vessels. Optionally, the fendering system may also provide a counter force to the tension of the lines and/or prevent slack in the lines.
[0095] Following are some exemplary embodiments of fenders: [0096] a) In one exemplary embodiment, tires may be used as fenders, which are cheap and plentiful, but have limited utility. [0097] b) In another exemplary embodiment, D-shaped fenders made of a resilient, rubber-like material may be used as fenders. The inside of the D shape is filled with air and the rubber-like material is firm enough to roughly maintain the D shape. Note: P-shaped fenders could also be used. This type of fender is not capable of a large amount of relative motion. [0098] c) In another exemplary embodiment, large floating fenders, such as that produced under U.S. Pat. No. 3,063,400A by Yamaguchi Minoru and Kobayashi Takashi and assigned to Yokohama Rubber Co Ltd may be used. These types of fenders are commonly referred to in the marine industry as Yokohamas. This type of fender is helpful when there is a large gap between the vessels and there is a large amount of motion.
[0099] All the components of the coupling system work together to form a complementary system that provides safe and secure coupling between the two watercraft.
[0100] The above description is intended to enable the person skilled in the art to practice the invention. It is not intended to detail all of the possible modifications and variations that will become apparent to the skilled worker upon reading the description. It is intended, however, that all such modifications and variations be included within the scope of the invention that is seen in the above description and otherwise defined by the following claims.
CONCLUSION, RAMIFICATIONS, AND SCOPE
[0101] Accordingly, the reader will see that a servicing watercraft that may be safely and effectively secured to another watercraft. Thus, the reader will see that at least one embodiment provides the following advantages:
[0102] A servicing watercraft that utilizes a sufficiently thin auxiliary section that can be positioned away from the main section of the servicing watercraft such that only the thin auxiliary section is placed under the hazardous section of a serviced watercraft. Therefore, if cargo were to fall from the serviced watercraft, it would fall past the thin auxiliary section, splashing into the water instead of impacting the main section of the servicing watercraft. This eliminates the need for a spacer, thereby providing the following advantages: [0103] a) The main section of the servicing watercraft is positioned away from the danger of falling cargo, thereby increasing safety, and reducing the risk damage, injury, or death from falling cargo. [0104] b) Decreases the reach required for an arm that would otherwise have to span between the servicing watercraft and the serviced watercraft, thereby reducing cost of the arm and increasing the width of vessels that may be serviced by a distance equal to the width of the eliminated spacer. [0105] c) Eliminates the time and expense for a second watercraft or tugboat to transport a spacer to the servicing location. [0106] d) Eliminates the need to store said spacer in a separate location than the servicing watercraft, thereby reducing slip fees. [0107] e) Eliminates the expense of said spacer. [0108] f) Eliminates the need for an additional tugboat to position and manipulate said spacer barge into position, thereby saving time and operating costs. [0109] g) An auxiliary section can be positioned quickly, compared to a separate spacer barge, thereby reducing the amount of time necessary, thereby reducing operating costs and increasing revenue. [0110] h) Reduces the distance that the servicing watercraft intrudes into the water space of a narrow channel which could otherwise cause interference with other vessels that pass by.
[0111] At least one auxiliary section may be positioned so to increase the effective width of a servicing watercraft thus providing the following advantages: [0112] a) Reduction in the amount of rolling motion when the watercraft is exposed to swells, wakes, and waves, thus reducing the amount of relative motion between the servicing watercraft and the serviced watercraft, thereby increasing safety. [0113] b) Eliminating the need that the servicing watercraft be built with a fixed increased width, thus reducing the cost of said servicing watercraft.
[0114] At least one auxiliary section of a servicing watercraft may be positioned to decrease the effective width of the watercraft thus providing the following advantages: [0115] a) Eliminating the requirement for a fixed extra-wide watercraft thus reducing the drag when the watercraft moves through the water, thereby reducing fuel cost. [0116] b) Allowing the servicing watercraft to better navigate through narrow channels and waterways. [0117] c) Allowing other watercraft to pass when the servicing watercraft operates in narrow channels and waterways.
[0118] At least one auxiliary section may be positioned adjacent to a section of the hull on a serviced watercraft that is a vertical surface, whereby the auxiliary section supports the main section of a servicing watercraft, even in the case where the main section of the servicing watercraft is not in full contact with the hull of the serviced watercraft, thus providing the following advantages: [0119] a) Eliminating the need to use floating fenders on the non-vertical sections of the serviced watercraft. Floating fenders are inconvenient, are complicated, take up space on the deck, and are time-consuming. [0120] b) Eliminating the need to constantly adjust at least one floating fender when the serviced watercraft raises or lowers in the water due to cargo loading and offloading and/or changes in ballast. [0121] c) Maintaining secure coupling between the servicing watercraft and the serviced watercraft while the serviced watercraft raises or lowers in the water due to cargo loading and offloading and/or changes in ballast. [0122] d) Maximizing the area of contact with the available vertical surfaces on the hull of the serviced watercraft, thus providing a robust and secure coupling between the servicing watercraft and the serviced watercraft. [0123] e) The main section of the servicing watercraft may be positioned away from the sections of the serviced watercraft that handle cargo, thus reducing the risk of falling cargo impacting the servicing watercraft. The safest location is typically adjacent to the superstructure of the serviced watercraft. However, on some vessels, the hull adjacent to the superstructure may not be vertical. [0124] f) The main section of the servicing watercraft may be positioned in the optimum location, even where there is limited or no vertical hull surface, while being supported by the offset auxiliary section which continues to be secured to an adjacent vertical aspect of the hull of the serviced watercraft, thereby reducing the arm reach required, which enables servicing wider vessels and reduces the cost of the arm.
[0125] A servicing watercraft may be oriented perpendicular to a serviced watercraft so that an arm may originate near the edge of the servicing watercraft that is adjacent to the serviced watercraft thereby eliminating the additional reach that would have otherwise been required for the arm to reach over half the width of the servicing watercraft, thereby increasing the net reach of the arm and/or reducing the cost of the arm and increasing the number of vessels that may be serviced.
[0126] A system that enables a watercraft to couple to another watercraft in waters with large swells, wakes, or waves such as outside the harbor, outside the breakwater, or in an area inside the harbor that suffers from unusually large swells, wakes, or waves.
[0127] While the above detailed description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of one [or several] embodiment(s) thereof. Many other variations are possible. For example,
[0128] In an exemplary embodiment, as shown in
[0129] In another exemplary embodiment, a separate floating section could be implemented as an alternative to the pivoting wings such that the floating section is kept with the main barge section loosely via lines, rope, or cables. In the non-deployed mode, the floating element would be manipulated to one of the sides or lifted to a storage location of the servicing watercraft. In deployed mode, the floating section could be manipulated to left-front, center-front, or right front of the servicing watercraft and secured. The floating section could be secured with rope or cable or by means of a mechanical attachment. The floating section may also be comprised of separate elements that may be attached together as required.
[0130] In yet another exemplary embodiment, the floating sections could stow in an angle up to vertical instead of horizontally.
[0131] In yet another exemplary embodiment, pontoons and/or outriggers at the end of swinging arms could be used instead of floating sections.
[0132] In yet another exemplary embodiment, the auxiliary section (wing) does not necessarily have to be floating section. The section may be cantilevered from the main section and may or may not include at least one supporting buoyant device along the cantilevered section.
[0133] In yet another exemplary embodiment, the servicing watercraft may be positioned nose-in to the side of the serviced watercraft and secured with lines, that is, the servicing watercraft is perpendicular to the serviced watercraft. Although this configuration moves the main section of the servicing watercraft away from falling cargo, falling cargo could still impact the lines, which would still cause damage to the servicing watercraft and/or serviced watercraft. This configuration would also not reduce the rolling motion of the servicing watercraft.
[0134] In yet another exemplary embodiment, the servicing watercraft uses at least one crane to stow the auxiliary section(s) until needed. When the servicing watercraft and the serviced watercraft are about to be secured together, at least one crane moves the auxiliary section(s) from the stowage location to the operating location. The auxiliary section(s) are secured, as several of many possible examples, with lines, ropes, cables, and/or mechanical mechanisms.
