[0027] FIG. 3 shows one exemplary embodiment of PECW 100 positioned directly adjacent to a serviced vessel 200, which is the traditional location of an emissions control watercraft. PECW 100 comprises barge 102, purification system 600, tower 400 (option), arm 500, and exhaust pipe connector 510. Serviced vessel 200 may be an oceangoing vessel (OGV) or ship, comprising superstructure 210, funnel 230, and exhaust pipes 220.

OPERATION

[0044] In one exemplary embodiment, as shown in FIG. 2, the spud columns 700 are raised thereby allowing transport of positionable emissions control watercraft 100 (PECW 100) across the top of the body of water. PECW 100 may be transported by one or more tugboats, or PECW 100 may be self-propelled, for example. When a serviced vessel 200, such as an oceangoing vessel (OGV) for example, comes to berth and is sufficiently moored into position, then PECW 100 is moved to any desired location within reach of the exhaust pipes of OGV 200, but with a sufficient distance between OGV 200 and PECW 100. While the spuds are still retracted upwards, PECW 100 is moved to a location where if cargo were to fall from OGV 200, the cargo would miss PECW 100 and splash into the water between PECW 100 and OGV 200. Furthermore, if bunker operations are planned during the vessel call, then PECW 100 may be placed at a sufficient distance away from OGV 200 such that a bunker barge 250 may fit between PECW 100 and OGV 200, thereby allowing both bunker operations and emissions control operations to take place at the same time. Alternatively, PECW 100 positioned sufficiently fore or aft along the side of OGV 200, so that both PECW 100 and bunker barge 250 can service OGV 200 concurrently. Cargo operations may be temporarily halted in the section above PECW 100 during the interval when PECW 100 is temporarily positioned to allow bunker barge 250 to share the same general location next to OVG 200.

[0045] This exemplary embodiment discloses four spuds, although any number of spuds could be used, although only a minimum two spuds are required, each spud comprising spud column 700, spudwell 710, and spud drive 720. Spudwell 710 functions as a vertical guide sleeve for spud column 700. Spud column 700 may be raised or lowered by spud drive 720. Spud drive 720 may be either a mechanical or hydraulic winch and line system, for example. In this exemplary embodiment, a steel cable that is attached to the foot of spud column 700 and is retracted by a hydraulic winch such that the spud column is lifted through spudwell 710 thereby allowing PECW 100 to travel along the water. The hydraulic winch could also be electrically-powered. Anyone skilled in the art can select, size, and install spud systems that are appropriate for an emissions control watercraft.

[0046] In one exemplary embodiment, as shown in FIG. 1, the spud columns 700 are lowered to the seabed thereby anchoring positionable emissions control watercraft 100 (PECW 100) and fixing the location of PECW 100 at the desired location and at a sufficient distance from OGV 200. Lowering a spud is accomplished by releasing any brakes and reversing the direction of the winch to pay out the steel cable which attached to the foot of spud column 700. Gravity pulls spud column 700 to the extent that the winch leases a length of steel cable, for example.

[0047] In another exemplary embodiment, as shown in FIG. 4, the spud columns 700 are lowered to the seabed thereby anchoring positionable emissions control watercraft 100 (PECW 100) and fixing the location of PECW 100 at the desired location and at a sufficient distance from OGV 200. Once PECW 100 is anchored in location, then arm 500 can be manipulated to bring exhaust connector 510 to an exhaust pipe 220. After connecting the exhaust capture system to an exhaust pipe 220 of OGV 200, then exhaust is drawn through the exhaust capture system and purification system 600, thereby releasing purified exhaust gas to the atmosphere.

[0048] In yet another exemplary embodiment, as shown in FIG. 5, PECW 100 is anchored in a location sufficiently distant from OGV 200 and PECW 100 is already purifying exhaust from OGV 200. In this exemplary embodiment, a bunker barge 250 has sufficient access to OGV 200 to be placed in the gap between PECW 100 and OGV 200. Thus, bunker barge 250 positions itself adjacent to OGV 200 and couples itself to OGV 200 using mooring lines or equivalent. Once bunker barge 250 is secured, then bunkering or fueling operations may begin. In the meantime, emissions continue to be treated by PECW 100 without interruption. When bunker barge 250 has completed servicing OGV 200, then bunker barge 250 is free to uncouple from OGV 200 and go to its next destination. Bunker barges typically have a beam (width) of 40 to 60, so the space formed between PECW 100 and OGV 200 needs to be sufficiently wide to allow bunker barge 250 to fit in the gap. Furthermore, arm 500 must have sufficient reach to be able to reach the furthest exhaust pipe 220 on OGV 200. Alternatively, PECW 100 positioned sufficiently fore or aft along the side of OGV 200, so that both PECW 100 and bunker barge 250 can service OGV 200 concurrently. Cargo operations may be temporarily halted in the section above PECW 100 during the interval when PECW 100 is temporarily positioned to allow bunker barge 250 to share the same general location next to OVG 200. The servicing watercraft may be positioned end-to-end next to the OGV 200 because PECW 100 does not require mooring lines, thereby eliminating the problem of crossing mooring lines so that PECW 100 and bunker barge 250 can service both service OGV 200 concurrently.

[0049] 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

[0050] Accordingly, the reader will see that a positionable emissions control watercraft may be safely and effectively positioned near a serviced watercraft in an optimum orientation relative to a serviced watercraft that 1) reduces the likelihood of damage from falling cargo, 2) eliminates the need for a spacer or spacer barge, and 3) allows other service craft to access the serviced watercraft. Thus, the reader will see that at least one embodiment provides the following advantages:

[0051] A positionable emissions control watercraft that is positioned an optimum location that is sufficiently away from a serviced watercraft significantly reduces the risk of falling cargo from the serviced watercraft. Thus, if cargo were to fall from the serviced watercraft, it would fall in the space between the two watercraft, thereby splashing into the water instead of impacting the positionable emissions control watercraft.

[0052] A positionable emissions control watercraft eliminates the need for a spacer, thereby providing the following advantages: [0053] a) The positionable emissions control watercraft may be located away from the danger of falling cargo, thereby increasing safety, and reducing the risk damage, injury, or death from falling cargo. [0054] b) Eliminates the time and expense for a second watercraft or tugboat to transport a spacer to the servicing location. [0055] c) Eliminates the need to store said spacer in a separate location than the positionable emissions control servicing watercraft, thereby reducing slip fees. [0056] d) Eliminates the expense of said spacer. [0057] e) Eliminates the need for an additional tugboat to position and manipulate said spacer barge into position, thereby saving time and operating costs.

[0058] A positionable emissions control watercraft that may be positioned in an optimum location that so that it is not required to contact the hull of the serviced watercraft, either directly or indirectly using spacers, thus providing the following advantages: [0059] 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. [0060] 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. [0061] c) Maintaining a secure relative position between the positionable emissions control watercraft and the serviced watercraft while the serviced watercraft raises or lowers in the water due to cargo loading and offloading and changes in ballast. [0062] d) A positionable emissions control watercraft may be positioned away from the sections of the serviced watercraft that handle cargo, thus reducing the risk of falling cargo impacting the positionable emission control 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. [0063] e) The positionable emissions control watercraft may be positioned in the optimum location, even where there is limited or no vertical hull surface.

[0064] A positionable emissions control watercraft that may be placed in an optimum location that is sufficiently far from a serviced vessel such that another servicing watercraft, such as a bunker barge, can concurrently be moved between the positionable emissions control watercraft and the serviced vessel so both servicing watercraft can concurrently serve the same serviced vessel.

[0065] A positionable emissions control watercraft that may be placed in an optimum orientation that is sufficiently fore or aft along the serviced watercraft thereby allowing another servicing watercraft to operate concurrently with said positionable emissions control watercraft.

[0066] A positionable emissions control watercraft that may be placed in an optimum orientation that is nose-in to the side of the serviced watercraft and anchored with spuds, whereas the positionable emissions control watercraft is oriented perpendicular to the serviced watercraft, instead of the traditional alongside placement. Since the width of a servicing watercraft is typically roughly equivalent to the width of the superstructure on the serviced watercraft, this orientation allows the positionable emissions control watercraft to be placed directly adjacent to the servicing vessel's superstructure to avoid falling cargo.

[0067] A positionable emissions control watercraft that may be placed in an optimum location that is oriented in an explosion-safe location near a liquid-bulk carrier (e.g., tanker) which is otherwise not be possible with the traditional mooring line approach. In this case, the servicing watercraft may be positioned aft of an explosive zone while also not touching to avoid rubbing against the serviced vessel which may cause sparks due to the generation of static electricity.
