The present disclosure concerns examples of portable containment structure for ship preservation.
BACKGROUNDShips are often subject to corrosive environments. Saltwater and proximity to saltwater spray create a reoccurring need for preservation efforts. Ships with flight decks often have particularly stringent needs for regular preservation due to safety of flight requirements and dangers caused by damaged or otherwise imperfect flight deck surfaces. In addition, the nature of flight deck operations, with recurring hits from helicopters during takeoff and landing, can cause damage to the decking material (often “nonskid” material). While these damaged portions can sometimes be superficial by themselves, they can lead to water intrusion to the metal substrate and increased corrosion at the damaged locations. After a prolonged period of flight operations in a saltwater environment, it is often necessary for flight decks to be completely stripped down to bare metal and refinished with new nonskid material.
Flight deck preservation and repair efforts can be time intensive and can often require near ideal environmental conditions. In regions where the weather does not support many consecutive days of clear dry conditions, it is often necessary to completely cover the flight deck in scaffolding or a similar structure and then wrap the structure a material such as plastic. This process is labor intensive and leads to delays in the repair efforts as the structure is constructed. Therefore, there exists a need for a structure which can be easily and quickly installed to expedite flight deck preservation activities.

Examples of the Disclosed TechnologyRepairing decks, such as flight decks on ships, can require near ideal environmental conditions. In some cases, the climate does not support these conditions, and it is desirable to cover the flight deck to allow control of the internal climate conditions while preservation is occurring. For example, a containment structure can cover the flight deck and prevent precipitation from hindering preservation efforts. Covering the flight deck during preservation work can also protect the work from airborne debris and/or contaminants and can help to ensure the quality of the preservation work is not degraded. In some examples, these airborne debris and/or contaminants can be created by parallel work being conducted in the shipyard or in nearby areas, such as debris from grit blasting or overspray from painting operations. Additionally, containment structures can provide environmental protections by helping to retain waste products created by preservation work on the flight deck within the containment device, which helps to keep the waste products from entering the surrounding environment. However, it can be time consuming and costly to erect these containment structures. In some cases, erecting containment structures can cost a shipyard days if not weeks of production time.
The current disclosure is directed to a containment structure which is partially or fully prebuilt and methods of coupling the containment structure to a ship. This can have the advantages of saving time and money. It can also improve the security of the containment structure, for example when faced with high winds. The containment structure described herein can reduce setup and breakdown times and provide schedule improvement by reducing setup time, in some instances from 2 weeks down to 1-2 days or less. In some examples, the containment structure described herein can further have the advantage of preinstalled explosion proof lighting and electrical systems. In some examples, the containment structures described herein can have the advantage of being less susceptible to wind and other environmental occurrences. In some examples, the portable containment structure described herein can withstand winds up of 100 mph or more.
In some examples, the containment structure can further comprise a vertical wall portion 120. In some examples, the vertical wall portion 120 can be configured to be positioned at the aft end of the flight deck 12. The vertical wall 120 can comprise one or more vertical supports 122 and one or more horizontal supports 124. A third side portion 126 can extend along the bottom of the vertical supports 122 and can comprise a first rail and as second rail similar to the first rail 113 and the second rail 115. The vertical wall portion 120 can be covered with a vertical cover 128.
In some examples, the cover 102 and/or the vertical cover 128 can comprise a continuous piece of material disposed over the one or more trusses 104, the one or more vertical supports 122, and the one or more horizontal supports 124. In some examples, the cover 102 and/or the vertical cover 128 can comprise a plurality of pieces of material coupled together. In some examples, the cover 102 and/or the vertical cover 128 can comprise a plastic film. In some examples, the cover and/or the vertical cover can comprise another material that is lightweight and provides protection against environmental conditions such as precipitation.
In some examples, the containment structure 100 may include additional features which may be useful, for example in a shipyard environment. In some examples, the containment structure 100 includes preinstalled electrical wiring and/or pneumatic hoses. In the example depicted in
The containment structure 100 can comprise one or more connectors 150 which can couple the containment structure 100 to the flight deck 12. In some examples, the connectors are distributed along the first side portion 112, second side portion 114, and/or the third side portion 126. In some examples, there is a connector 150 positioned the first end portion 106 of each truss 104. In some examples, there is a connector 150 positioned the second end portion 108 of each truss 104. The connectors 150 can provide lateral retaining forces, for example they can help prevent the containment structure 100 from slipping in the port to starboard directions and/or the forward to aft directions. In some examples, the connectors 150 disposed on the first side portion 112 and second side portion 114 can provide retention force in the port to starboard directions and the connectors disposed on the third side portion 126 can provide retention force in the forward to aft directions.
The containment structure 100 can also be coupled to the flight deck 12 by mechanisms in addition to the connectors 150. As depicted in
The cover 102 can include one or more skirt portions 116 which can be sized and shaped to selectively cover the aperture 118 between the cover 102 and/or the vertical cover 128 and the flight deck 12. In some examples, the aperture 118 can be the result of the connectors 150 having a height off the flight deck 12. When the user needs to access the area outboard of the portable containment structure 100, the skirt portion can be raised and the user can reach through the aperture 118. When the user does not need to access the area outboard of the portable cover, the skirt portions 116 can be lowered and secured in place such that the skirt portion 116 covers the aperture 118. In some examples, the height of the connectors 150 is in a range of 1 foot to 4 feet. In some examples, the height of the connectors 150 is between 1.5 feet and 3 feet. In one example, the height of the connectors 150 is 2 feet.
In some examples, portions of the connector element can remain coupled to the first rail 113 and second rail 115 of the containment structure 100 while it is being delivered or removed from the ship and other portions of the connector 150 can be installed once the containment structure 100 has been positioned on the flight deck 12. In some examples, the connectors 150 may be installed on the flight deck first and then the remainder of the containment structure 100 may be placed on the connectors 150.
The receiver portion 170 can be sized and shaped to receive and couple to one of the first side portion 112, the second side portion 114, and/or the third side portion 126. The receiver portion 170 can comprise one or more U-shaped receiver elements 154 which can have openings 157 into which the first rail 113 and/or the second rail 115 of the first side portion 112 or the second side portion 114 can fit. In some examples, the receiver portion 170 can further comprise one or more cross pieces which can provide structural support. In the depicted example, the receiver portion 170 comprises a single cross piece 155 which extends between the receiver elements 154. In the depicted example, the connector 150 comprises two receiver portions 154 which are configured to receive the first rail 113 and the second rail 115, as depicted in
The strut portion 172 may comprise one or more struts, which can extend vertically between the base portion 174 and the receiver portion 170. In the depicted example, the strut portion 172 comprises two struts 156 which are shaped in a V. In other words, the struts 156 are adjacent to one another where they are coupled to the base portion 174 and are offset from one another where they are coupled to the receiver portion 170. This can have the advantage of receiving the weight of the containment structure 100 and focusing the downward force on a central part of the base portion 152. In other examples, there may be different numbers of struts or the struts may be form different shapes. In some examples, there may be a single strut. In some examples, there may be two struts which extend parallel to one another, for example, straight up and down. In some examples, the struts may extend straight up and down and have a cross piece to form an H-shape. In some examples, the strut portion may be omitted all together and the receiver portion 170 may be coupled directly to the base portion 174.
The base portion 174 can comprise a base plate 152 and one or more coupling portions. The base plate may comprise a first side 192 (as depicted, the “upper side”) and a second side 194 (as depicted the “lower side”). The second side is configured to sit on top of the raised plate 16 on the edge of the flight deck 12. The base plate may be wide to allow the containment structure 100 to be used with flight decks of different sizes. In the depicted example, the base plate has a first width 176. In some examples, when the containment structure is placed on a ship with a larger flight deck, the raised plate 16 may be positioned on an outboard portion of the base plate 152. In some examples, when the containment structure is placed on a ship with a smaller flight deck, the raised plate 16 may be positioned on an inboard portion of the base plate 152. Having a wide base plate 152 on the connector 150 allows the same portable containment structure to be used with a variety of classes of ships with different sized flight decks.
The base portion 174 may further comprise one or more coupling elements. In the depicted example there is one coupling element which can be removably coupled to the base plate. In some examples, the coupling element may comprise one or more first coupling portions disposed on a first side 192 of the base plate and one or more second coupling portions disposed on a second side 194 of the base plate which are portions are configured to releasably couple the base plate to the ship. The coupling element may be narrower than the base plate 152, this allows the position of the coupling element to be adjusted along the width of the base plate. In the example depicted in
In use, the containment structure 100 can be delivered to a ship's flight deck, as described above, and the base plate 152 of the connector 150 can be positioned on the raised plate 16. Once the containment structure 100 is positioned in a predetermined position, the user can install the first coupling elements 165 and the second coupling elements 166. For example, the user can pass the second coupling elements 166 under the second side 194 of the base plate 152 such that they are parallel to the raised plate 16. Then the first coupling elements 165 can be positioned on the first side 192 of the base plate 152 and the bolts 163 can be passed through the through holes 162 and secured in place. The containment structure 100 can be further secured to the flight deck using straps 130 as described above.
The containment structure described above can have the advantages of saving time and money. The connectors can improve the security of the containment structure, reduce setup and breakdown times, and provide schedule improvement. In some examples, the containment structure described herein can further have the advantage of preinstalled explosion proof lighting and electrical systems.
