Description

The present invention relates to a mobile training unit, particularly but not exclusively based on an ISO ‘40 foot’ cargo container and able to provide training in relation to confined/enclosed spaces, working at height, fall potential and rescue situations.
Training of operatives to work in particular situations such as confined spaces, heights, and the like, can be carried out at dedicated training centres. However, such training facilities generally only provide one sort of training, and are usually provided by costly third party vendors within their own premises. Furthermore, there is the additional cost of bringing personnel to each and every type of facility required. Such costs increase where training is related to water-based, sea or off-shore situations, especially training in relation to working on sea-going vessels and off-shore facilities like oil rigs and platforms.
U.S. Pat. No. 7,244,123 B1 shows a self-contained training device for simulated personnel entry, exit and rescue in confined space scenarios. The training device features an enclosed tank mounted on a truck trailer. However, the training device of U.S. Pat. No. 7,244,123 B1 is only based on (and fixed to) a truck trailer, with facilities designed for confined space scenarios only.
It is an object of the present invention to provide an improved multi-purpose mobile training unit.
Thus, according to one aspect of the present invention, there is provided a mobile training unit comprising a transportable cargo container having a transport position and at least one training position, the cargo container comprising:
(a) at least one confined working compartment wholly or substantially within the cargo container dimensions;
(b) at least one cargo container wall portion movable between a closed transport position and an open training position;
(c) at least one door for entry into and exit from the cargo container; and
(d) a tower movable between a transport position within the cargo container dimensions, and a training position extending beyond the cargo container.
The mobile training unit of the present invention in its transport position provides a very convenient unit for easy transportation to different locations where training is necessary or desired. This mobile training unit can at least supply facilities to provide training in relation to confined/enclosed spaces, working at height, fall potential and rescue situations
The cargo container could have a multitude or plurality of training positions. The or each training position could be based on static and/or dedicated areas in the cargo container, and/or the movement of one or more portions of the mobile training unit and/or one or more portions of the cargo container between a transport position and one or more training positions. This can include movement of one or more portions of a surface of the cargo container, such as one or more portions of any side walls. This can also include movement of one or more portions of the mobile training unit within the cargo container, including but not limited to the tower and/or one or more other additional apparatus of the mobile training units such as guard rails and the like, as well as the movement of one or more internal surfaces such as internal dividers, walls, partitions, etc.

The mobile training unit may comprise one or more further apparatus or devices or attachments movable between a transport position and one or more training positions, and be able, singularly or in combination with one or more other embodiments described herein, to provide one or more further training scenarios. Such further apparatus, devices or attachments may be separable from the cargo container between the transport position and the training position(s), and/or extend from the cargo container or a portion thereof to increase the similarity of the training scenario with the real working locations.
In another embodiment of the present invention, all equipment, apparatus, devices and/or other facilities or functions of the mobile training unit can be locatable within the cargo container dimensions for transportation thereof. In this way, the cargo container, especially when it is a regular shape such as a 40 ft (12.2 m) ISO container, is as efficiently transportable as existing 40 ft (12.2 m) ISO containers used for transportation of goods.
The present invention encompasses all combinations of various embodiments or aspects of the invention described herein. It is understood that any and all embodiments of the present invention may be taken in conjunction with any other embodiment to described additional embodiments of the present invention. Furthermore, any elements of an embodiment may be combined with any and all other elements of any of the embodiments to describe additional embodiments.

An embodiment of the present invention will now be described by example only, and with reference to the accompanying drawings in which:

FIG. 1 comprises a series of six views of a mobile training unit in a transport position according to one embodiment of the present invention;

FIG. 2 comprises a series of six similar views of the mobile training unit of FIG. 1 in a first possible training position;

FIG. 3 is a perspective view of the mobile training unit of FIG. 1;

FIG. 4 is a perspective view of the mobile training unit of FIG. 1 with the addition of removable guard rails, taken from storage within the cargo container during transportation to the training positions shown;

FIG. 5 is a perspective view of the mobile training unit of FIG. 1, showing two moveable wall portions in training positions to provide a working platform; and FIG. 6 is a perspective view of the mobile training unit of FIG. 1 showing the tower in its vertical training position.

The mobile training unit of the present invention can provide an economical and mobile unit that is reliable, durable, and flexible enough to provide both working at height, advanced rescue, and confined space training.
The mobile training unit is easy and convenient to use, and its mobility means it can be deployed to various locations. The mobile training unit can therefore bring the training to the user or client, rather than the client to the training thus significantly saving man-hours, and as a result of this, the unit provides a more cost effective solution to training that also reduces the impact on personnel utilisation and leave time.
The mobile training unit is able to supply a safe and controlled environment for providing trainees with the knowledge and skills required to work safely at height, and/or in and around confined and enclosed spaces. With input from experienced instructors, the unit can be designed or adapted to accurately replicate or duplicate the challenges and problems found around many types of workplaces and workplace situations whilst working at height or in confined/enclosed spaces. This includes but is not limited to those work situations found on sea-going vessels.
The mobile training unit can incorporate performance based learning techniques. Constant instructor supervision can allow mistakes by users to be immediately corrected when necessary. The training unit and the exercises that it facilitates can be standardised to achieve a high level of effectiveness. Standardisation means the training can be consistent. This provides continuity for personnel and teams when working in or on differing or different workplace situations and sites.
The mobile training unit is preferably housed within and fabricated around an ISO standard 40 ft (12.2 m) container. The use of a cargo container as the base structure can greatly reduce the cost of providing such a training unit, as such containers are readily available and can possibly be purchased and then modified. Efficiencies that come with established manufacturing procedures result in cargo containers being relatively inexpensive. The mobile training unit preferably abides by all necessary specifications for Shipping and Road Transportation.
The mobile training unit preferably has one or more of the following criteria:

Mobility Such a training unit should be completely mobile, meaning training can be done at any site, eliminating the need for trainees to travel. Housing the training unit in an ISO standard-type container allows easy and convenient transportation by sea and road.
Realism Such a training unit should be able to carefully replicate many of the problems encountered regularly by workers and rescuers in confined spaces and when working at height.
Safety Such a unit should provide a safe and controllable learning environment that allows constant instructor supervision where trainee mistakes can be immediately detected and corrected. This can include multiple access and egress points for quick rescue.
Professionalism Such a training unit should to provide all the necessary equipment for trainees to be trained, tested and certified to the necessary levels of professional competence.
Cost Such a unit should seriously reduce the costs of training by removing the need for travel. Although training is on site it remains out with critical paths, so there is no disruption to operations. Training may be scheduled to work around employee availability and shift schedules.
Efficiency Training and the unit should be designed to optimise the number of trainees taking part at any one time, i.e. the possibility of simultaneous working at height, and advanced rescue training.
Independence Set-up of such a unit from the transported container should happen with minimum input from equipment that is not part of the container unit. This reduces the need for crane time, forklifts, and other machinery.

Referring to the drawings, FIG. 1 shows left, end, right, left iso, top and right iso views of a mobile training unit in a transport position, according to one embodiment of the present invention. The mobile training unit 2 comprises a cargo container 4 having the dimensions of an ISO 40 ft (12.2 m) cargo container, being based on and/or adapted from a known ISO 40 ft cargo container design.
The cargo container 4 has a cuboid shape having two elongate sidewalls 6, 8, a top 10, a base (not shown) and two end portions 12, which together form a securable enclosure for easy transportation. Each end portion 12 has two doors 13.
Each sidewall 6, 8 comprises an upper wall portion 14 and a lower wall portion 16. Each lower wall portion 16 includes three man holes 18 spaced therealong.
The top 10 shows an arrangement for the division of at least the upper space within the cargo container 4 into three portions, comprising a first area that could define a first confined working compartment 20 having a first hatchway 22, a second area that could define a second confined working compartment 24 at the opposite end of the cargo container 4 to the first compartment 20, and having a second hatchway 26, and a middle portion 28 further described hereinafter.
FIG. 1 shows the cargo container 4 in its transport or transportable position or set-up. The regular shape of this set-up means that transportation is made easy, be it on the back of a lorry, trailer or on a rail-carriage for land transportation, as well as easily transportable on a seagoing vessel, in the same manner as conventional ISO 40 ft (12.2 m) containers.
FIG. 2 shows the same left, end, right, left iso, top and right iso views of the cargo container 4 shown in FIG. 1, now in a first training position. In this first training position, the upper wall portions 14 of the two longitudinal side walls 6, 8 have been moved from their transport position as shown in FIG. 1 (being in alignment with the lower wall portions 18 of the sidewalls 6, 8 so as to form flat sidewall surfaces), to perpendicular raised open training positions 30, being parallel with the top 10, and wholly or substantially in alignment with the top 10, so as to form overall a raised platform area 32 that spans across the top of the cargo container 4. Any suitable means of adjustment, such as one or more hydraulic rams (not shown), for example two rams per upper wall portion 14, can be used to provide movement of the upper wall portions 14 in this way.
The raised platform area 32 creates a training scenario realistic to sea-going vessels. The raised platform area 32 also provides shade under the open training positions 30 of the upper wall portions 14, which could be useful when the mobile training unit 2 is located in warmer climates.
Confined/enclosed space training in the mobile training unit 2 can be provided in a 1 m high area 34 along at least part of, optionally along substantially or all of, the bottom of the cargo container 4 in line with the lower wall portions 16 of the side walls 6,8. This confined space area 34 may also be connected to and/or utilise a 6′×8′×8′6″ (1.8 m×2.4 m×2.6 m) section in the cargo container 4 for vertical confined space training.
The confined space area 34 may extend across the entire width of the container's floor, and have within it features and obstacles to provide confined working training as herein described above. This area 34 can provide a horizontal element of the confined space training. This can involve users, trainees or other personnel travelling from one end of the container 4 to the other while overcoming obstacles. Obstacles encountered in this area 34 can include vessel hatch entry, horizontal passageways, right angle obstacles and internal baffles.
A vertical element of confined space training can be provided by the use of a split level 6′×8′×8′6″ (1.8 m×2.4 m×2.6 m) area, for example in the first confined compartment 20 at one end of the container 4. This first compartment 20 can include two levels with offset vessel hatchways 22 leading to a platform on top of the container 4. The platform can provide a location for situating a portable tripod (not shown) for performing vertical rescues.
Moveable and replaceable features, such as moveable/replaceable walls and drop down hatches can bring variation to the training scenarios. For example, wall panels in different sizes and dimensions can be provided so that the interior of the container 4 may be configured or partitioned into a multitude of spaces, compartments, rooms or areas of different sizes and shapes to assist in training.
Access to the confined space area 34 may be possible from multiple locations, such as through a 6′×4′×8′6″ (1.8 m×1.2 m×2.6 m) storage area, the vessel hatch entries 22, 26, and/or through the double doors 13 located at each end 12 of the container 12, or optionally just at the split level vertical confined space.
Ventilation to the confined space area 34 can be provided by man holes 18, windows, or other viewing ports, and/or access doors in the sidewalls 6, 8, and/or sections of grillage across the upper surface or top 10. The ports and hatches, etc. may be selectively opened to provide the desired amount of ventilation.
In addition to viewing windows, one or more ventilation hatches could be provided in the or an upper surface of the container.
FIG. 3 shows a perspective view of a mobile training unit 2 being a cargo container 4 as shown in the left iso view of FIG. 1.
FIG. 4 shows an option of providing one or more guide rails, such as two sets of guide rails 40, from a storage location within the cargo container 4 to be located on the sides of the cargo container 4, preferably extending around three sides of each upper wall portion 14 of each sidewall 6, 8 in a transverse direction as shown in FIG. 4.
FIG. 5 shows a perspective view of the upper wall portions 14 of the sidewalls 6, 8 in their open training positions 30 as shown in FIG. 2, in combination with the guide rails 40 therearound. This provides a raised platform area with guide rail safety.
FIG. 6 shows the cargo container having a tower 44, movable from a transport position within the cargo container dimensions, as shown in FIGS. 1-5, to a training position as shown in FIG. 6 extending beyond the cargo container 4. The tower 44 is attached to a panel 46, which can equate to the middle portion 28 of the top 10 of the container 4 as shown in FIG. 1.
Any suitable means of adjustment, such as one or hydraulic rams, permit movement of the tower 44 from its stored transport position to its vertical training position. Such hydraulic rams or the like can be positioned in the available space of a 6′ storage and power compartments.
The tower 44 provides for the working at height training. The moveable tower section can be 12 ft (3.7 m) in height, and when combined with the existing 8 ft container height, provides a 20 ft (6.6 m) overall height. The width of the tower 44 can be 5 ft (1.5 m), and length 4 ft (1.2 m), so that the tower 44 can fit within the overall container dimensions of a known ISO 40 ft (12.2 m) container.
The tower's structure can be constructed of 40 mm×40 mm box steel, which provides adequate strength and size for training routines.
Incorporated in the tower 44 is an internal ladder to provide access to a platform 48 situated on top of the tower 44 via a hatchway in the platform flooring. This internal ladder can be located on the inside of the tower's aft face, being the panel 46.
A backscratcher ladder 50 or ladder with safety-cage is mounted on the outside of the tower's side to run the full length of the tower 44. A removable/extendable ladder portion can be added to the backscratcher ladder 50 or ladder with safety-cage to extend it to a lower platform within the container 4. The platform 48 situated on top of the tower 44 is accessible from the backscratcher ladder 50 or ladder with safety-cage through a secure gate (not shown).
Located on top of the tower 44 could also be a removable davit for inertia reel and emergency evacuation.
The tower 44 and its environs provide training in relation to working at height situations.
Various modifications and variations to the described embodiments of the invention will be apparent to those skilled in the art without departing from the scope of the invention as defined herein. Although the invention has been described in connection with specific preferred embodiments it should be understood that the invention as defined herein should not be unduly limited to such specific embodiments.
