The present invention relates to transport containers, and more particularly to transport containers for intermediate bulk containers (IBC).
Transport containers, or IBC lifting frames, that are currently on the market do not allow IBCs containing dangerous goods, including liquids and granular materials, to be handled and lifted or carried on open seas or waters and also meet DNV 2.7-1 lifting standards. These transport containers are also not fully enclosed and thus do not fully protect IBCs from damage to the sides or top of the transport container.
Existing transport containers for IBCs do not meet the criteria specified by DNV-GL for certification of offshore containers intended for the transport of IBCs containing dangerous goods in offshore applications. These configurations potentially allow for a puncture to the sides and top of the IBC contained within them. Similarly, they do not protect the top gasket of the IBC from damage or entanglement with, for example a frame sling set.
As can be seen, there is a need for an improved transport container that enables customers to transport approved IBCs containing dangerous goods in an offshore environment, or to lift and transfer the IBCs, from an offshore service vessel to offshore locations in a manner which meets DNVGL-ST-E271, EN 12079:2006, IMO Circular MSC/Circ. 860, and API 2CCU Standards.
In one aspect of the present invention, a transport container for shipment of an intermediate bulk container (IBC) is disclosed. The transport container includes a lifting floor supporting an enclosed structure defining one or more bins within the transport container for containing the IBC. A left sidewall and a right sidewall are attached to the lifting floor. At least one movable wall is attached to one of the left sidewall and the right sidewall via a hinge for each of the one or more bins. The at least one movable wall is moveable between an open condition, permitting a lateral loading of the IBC within the one or more bins, and a closed condition, in which a side of the IBC is protected from a strike hazard when carried within the transport container. A plurality of clevis attachments are attached to a top end of the transport container. The plurality of clevis attachments are configured to carry the transport container in a suspended condition by a shipping sling. A moveable top lid is provided for each of the one or more bins defined within the transport frame. The top lid is movable between an open condition, permitting a top loading of the IBC within the one or more bins, and a closed condition in which a top end of the IBC is protected from a strike hazard within the transport container.
In some embodiments, the transport container also includes a track extending along a top edge each of the left sidewall and the right sidewall. A stop is defined at an end of the track. A pin protrudes from an intermediate position of a left and a right lateral edge of the top lid. The pin is carried within the track, and the top lid is configured to pivot to the open condition about the pin when the pin is positioned proximal to the stop.
In some embodiments, a latch assembly is attached to the at least one moveable wall, the latch assembly configured to secure the movable wall in a closed condition.
In other embodiments, a stabbing guide protrudes from an interior surface of the left sidewall, the right sidewall, the movable panel. The transport container may also include an alignment plate attached to an interior corner of each of the one or more bins. The alignment plate is configured to guide the IBC to a shipping position within the one or more bins.
In other embodiments, an interior dividing wall extends between adjacent bins of the one or more bins. In certain embodiments, the transport container may also include a ladder attached to at least one of the left sidewall and the right sidewall. A forklift pocket may be defined in a side edge of the lifting floor.
In other embodiments, a track extends along opposed lateral sides of the top end of the transport container. In this embodiment, the top lid includes a flexible panel that is carried within the track. A curved portion of the track is formed at the junction between the top end of the transport container and the sidewall of the transport container. The curved portion is configured to carry the flexible panel between the closed position and the open position. The track may have a length along the sidewall sufficient to carry the flexible panel.
In yet other embodiments, a plurality of parallel tracks extend along opposed sides of the top of the transport container. At least one of the top lids is carried within at least one of the plurality of parallel tracks, the at least one of the top lids is moveable within the at least one of the plurality of tracks between the open position and the closed position. A first top lid is configured to laterally slide within a first track so that it is positioned in one of a covered or a covering position relative to a second top lid that is carried within a second track.
In other aspects of the invention, a top closure for a transport container, is disclosed. The top closure includes a track defined along opposed lateral sides at a top end of the transport container. A top lid formed as a substantially flat plate that dimensioned to cover a bin opening at the top end of the transport container. A pin protrudes from a lateral edge of the top lid from an intermediate position of the lateral edge. The pin is received within the track and the top lid is movable along the track.
A stop may be included at an outer end of the track. When the pin is positioned proximal to the stop, the top lid is adapted to pivot about the pin to an open position. Preferably, the the pin is positioned proximal to a midpoint of the lateral edge.
