Rhino Becomes exclusive licensee for arch profile blastwalls and stainless steel explosion relief panels for emerging technologies – May 2019

The technology owned by Inoventech Ltd and extensively used in Europe, Azerbaijan, Far East and Australia has seen further development and is now exclusively licensed to Rhino Systems Ltd on a worldwide basis. Rhino systems Ltd is able to manufacture products and supply prefabricated units to customers worldwide. This follows on from the partnering agreement signed last year with Rapp Bomek that permits both companies to provide offshore doors and blast wall/escape tunnel solutions.

Blastwalls

The patented arch profile tackles the problem of the onset of local buckling that hitherto has limited the capacity for ductile bending of large corrugated profiles. It is available for design blast pressures up to 4 bar and spans to 13m. Typical allowable ductility ratio of 3 significantly reduces required static strength for specified dynamic blast resistance and reduces profile thickness and support reactions.

The way this is achieved is shown Figure 1 which illustrates the progressive development of the concept over time. Double sided arch profiles are also available.

The use of thinner material makes the use of austenitic and high strength duplex stainless steel economic. Not only does this improve the longevity of safety critical blastwalls in corrosive marine environments but the higher temperature resistance enables temperatures up to 1100C to be withstood without the need for passive fire protection.

It ensures competition with carbon steel bulkhead walls which, due to their load-bearing function, are limited to temperature rise of 450-550C,  thereby requiring the use of PFP. This is illustrated in Figure 2, produced by UK steel construction Institute (Fire and Blast Information Group).

Figure 2 why arch profile blastwalls have higher temperature resistance than bulkhead walls.

The arch profile walls are roughly half the overall depth of equivalent bulkhead walls due to absence of main vertical beams. This has space saving advantages for platform equipment layouts.

Compliant supports are part of the supplied walls and are particularly easy to incorporate into topsides structures and can be installed later in the build process, allowing extended blast design optimisation.

In project terms main blastwalls are supplied as part of a package which includes cladding walls, which are usually stainless steel and are also offered by Rhino Systems Ltd.

Explosion Relief Panels and walls

Explosion relief panels are offered for various applications:

  • Gas compressor buildings.
  • Hydrogen fuel cell charging stations and nuclear power plant.
  • Engine room protection for LNG and hydrogen powered ships.
  • Blast mitigation for enclosures in arctic areas.

ERPs can be supplied in prefabricated cassette form or in kit form like conventional wall and roof cladding in lengths up to 6m. Cassette form has integral beams capable of spanning up to 6m and kit form has beams for spanning between normal C section purlins but with integral lateral stabilisers for the purlins.

The opening principal of the proprietary ERP of 1100mm width is shown in Figure 3. Other widths are available.

Figure 3 showing opening principal for Rhino Systems hinged explosion relief cassettes.

Hinged ERP’s are more effective in relieving explosion pressures than conventional cladding as they open up wall area for venting earlier in the explosion process. This is demonstrated by FABIG Technical Note 2, “Explosion Mitigations Systems” Ch. 5.

The ERP’s have the added advantage that harmful projectiles are avoided, thereby limiting damage spread and injury risk in explosions and has been demonstrated in tests.

Figure 4 shows the cassette based system shown in Fig 3 for use on hydrogen refuelling stations, destined for use on converted ISO containers or bespoke higher strength module options (which incidentally can be supplied by Rhino Systems complete with doors). The explosion relief panels cover the whole roof and are delivered as a single large cassette which incorporates roof beams to provide simple structural replacement for the conventional corrugated roof which is removed.

For emerging green energy solutions the high speed relief roofs for very reactive hydrogen have been developed for ISO containers. The designs are currently under evaluation by GexCon in Norway based on the international HySEA project. These high speed panels reduce peak pressures in the protected modules, compared to conventional ERPs.

Figure 5a and 5b show cassette form ERPs certified for use in a gas compressor station (external and internal view) these units have additional requirements for fire protection and sound reduction, as sometimes required for buildings located near communities. They have external beams with downward projecting flanges which provide extra assurance against projectiles and protection of ice build-up from freezing rain.

ERPs have been subject to full scale explosion tests at GexCon’s test site in Norway.

For LNG or H2 gas powered ships (Figure 5c), ERPs relieve into void spaces which communicate to external shipside mounted ERPs located above uppermost watertight deck (also Rhino supply).

Announcing Project Bicornis – August 2017

bollard 1

bollard 2

As part of Rhino’s strategic growth plan over the last 12 months, efforts have not surprisingly been focused on improving and expanding the range of high performance doors that we can supply – achieved through a combination of internally funded product development and also strategic partnering agreements. In addition to this, Rhino has over the last 12 months been pursuing development of a new product that will place Rhino as a more complete physical security provider by offering perimeter and pedestrian protection systems. This is known internally as Project Bicornis.

The company’s new product are Anti-ram retractable security bollards:

Automated security bollards of this type are installed in public areas outside “soft targets” where there is threat of HGV vehicles ramming the buildings with explosives or more directly where members of the public are the target. Anti-Ram bollards block vehicular access without inhibiting pedestrian traffic flow. Monitored and centralised control of these bollards is also required to facilitate vehicular access for emergency services.

PAS68 is the latest Publicly Available Specification for vehicle security barriers and when designs are complete, Rhino will apply for accreditation to this standard. PAS68 has become the UK’s standard and the security industry’s benchmark for HVM (Hostile Vehicle Mitigation) equipment, and is the specification against which perimeter security equipment is tested as part of the ongoing research to prevent VBIED (Vehicle Born Improvised Explosive Device) attacks.

The recent recruitment of our new Chief Engineer Dr Chris Norris will allow Rhino to accelerate development of this safety critical new product, where it hoped that prototype testing will commence inside the next 6 months.

Further details to follow.

Successful Relocation

factory

Rhino are pleased to announce the successful completion of the relocation of all office and manufacturing based activities in Port Talbot to new, larger and more efficient facilities based very close to original location.

These new facilities provide us initially with a 20% increase in shop floor manufacturing area and this will increase to a 70% increase inside the next 12 – 18 months. Even this relatively modest 20% increase in area, coupled with a vastly improved manufacturing process flow layout (facilitated by two overhead gantry cranes, each of 7.5Te capacity) means that we now have the capacity to produce up to 4x as many doors compared to the original factory.

The new site also benefits from greatly improved office facilities that provide ample meeting/conference rooms, a video conferencing suite and plenty of space for expansion as the company grows.

Commenting on the recent move, Managing Director Stuart Lawrence said “The relocation of Rhino Doors to larger, more efficient premises is long overdue and we are delighted to be here. Not only have we removed the historical production capacity bottleneck that we used to suffer but we have also created for ourselves sufficient additional capacity to meet the demands of future projects, in line with our product development expansion plan”.
