    The present Invention concerns a five protested steel structure and removable panels for four proteofiori of a steel structures. The panes are Intended for covering steel structures such as tubular elements, girders, tanks, flanges, valves, columns, panels, walls etc. in particular for offshore installations, process plants, vessels, or anywhere metal structures are used in ah environment where tire protection is an issue. in fires in or dose to carry steel structures, it is of considerable importance that the structures are sufficiently protected to maintain the furictionaltty and ability to carry load. The steel sfriiciures may be of any shape, for instance cylindrical, square, shaped as girders, oolurrins or walls.
    Fires that occur: in instance hydrocarbon jaMUcing: or processing installations may threaten the structural integrity of the carrying steel structures fgirdersfeoiymrss} of the installation. Failure © for a load carrying steel structure © for an installation may lead to significant damage to both personnel and equipment and may result in canslderable pollution,
    Accordingly, it; has been proposed to provide such installations with some sort of passive heat insulation, seeking, reducing the. thermal release on the structure of the event: of a fire, Wtert such fire insulation Is tested, resistanoe against jets and hydrocarbon fires, fite and explosion loads should also be documented.
    There are various requirements and standards for passive © fire and explosion protection of steel structures throughout the world. In most cases a load carrying steel structure should be able to resist both jet and hydrocarbon fires from 80 to 120 minutes without the radiated temperature exceeding 400 eG. The steel structures should in most cases also be able to withstand an explosion pressure of up to 0.3 bar. : A: Flame temperature during Jet m hydrocarbon tires may exceed: way beyond 1300¾.
    Examples of such standards include Nomok Standard S - D01N and E-004, UL Standard Fire resistance Rating ANSI ill. 263 and ÅN81 / UL $ 170, The solution © of the present invention meets these standards.
    Current .passive fire protesting solutions require load restraint. sleet structures usually include expandable / tintdéteseenf, fire insolating epoxy substances or content based light weight concrete. These substances are sprayed directly onto the atruclum to. be proteeted.
    This solution has some obvious disadvantages. Chisel and chisel. hammer must normally be used to remove the fire protecting substance from the structure. Tools (for instance angle grinder) that heat the fire insolafing substance should not be used as toMte hydrocyanic acid gases may develop. Inspection of welding zones, corrosion damage, corrosion protective coatings or any repair work or modifications is difficult when the protected structure is coated directly onto the surface,
    Fire insulation epoxy substances are very difficult to apply In places with high humidity. Cement based light concrete is primarily used in these conditions. Light concrete that can be sprayed, however, is more impervious and absorbs humidity that contributes to corrosion. Furthermore, concrete has a tendency to deteriorate In time where the fire protecting properties are reduced, A problem when using epoxy based substances is that high temperature is required.during application, and: that the equipment used is not suitable for use in oil and gas installation duo to the fire and explosion hazards. Substantially all the passive fire protection on oil and gas insfaffaiiohs is applied manually «. There are also significant problems with fire insulating epoxy substances in terms of B8E. Hazardous gases are released during application and in the period when the epoxy safe, This typically leads, to epoxy allergy with: the personnel, thus preventing any further work with © poxy. It is an object of the present invention to provide a solotphone that meets the required standards, that does not promote corrosion, that does not absorb humidity, that has a reasonable weight, that allows inspection of the structure to be protected, that is easy to produce, that can be adapted to fee used oh å multitude of structures and that can be used under @ 1! Relevant climatic conditions, Fuitherniore, It is an: object to provide a solution with a life span of 25 years without substantial maintenance, if is also a purpose of the present inveniion to provide a system that can be installed without having to shut down the structure to be protected (eg an offshore piatfermTfer application. Furthermore, a purpose is to provide a system that can be installed 'in spite of an explosion hazard environment. The solution should also satisfy all relevant requirements for HSB within the relevant sectors such as withfn the oil and gas industry.
    An important feature of the invention is that instead of applying fit © passive fir® protection directly onto the structure to be proteot®cl, prefabricated fire proteoting panels are installed onto the structure to be protected while. maintaining suitable, conditions related to ventilate, temperature® and humidity. The solution of the present. .Invention includes panels that are easy to remove for easy inspection of for instance welding, zones, cheoh for corrosion, cracks, deformation and corrosion protecting coatings. The removable: panels may also be adapted for a; multitude of uses and as they are easy to remove, attachment of various equipment, repair operations spirit: modifications Is tedlitated,
    The panels can be installed in environments exposed to fire and explosion hazards without requiring explosion protected equipment
    The epoxy layer used in tie panels according to. the invention will typically begin to expand when exposed to temperatures of more than 20CFC. The layer typically expands tsTiva times the Initial thickness when exposed to jet and hydrocarbon: fims * It is this expanded epoxy layer that: provides the thermal irssulafim during fire. There should always be distance between the protective panels and the structure to allow for this expansion. Tilø necessary distance will, dearly depend on the thickness of the expanding layer. The fire protection requirements, the thickness of the material to be protected and the time the material to be protected must protect Its integrity and decisive factors for determining the thickness of the epoxy layer.
    The panels have very low thermally insulating properties before they are exposed to heat, this is favorable as Ideally the panels have the same temperature® on the inside and outside Id prevent condensation on the structure to prevent corrosion.
    The panel joints should generally be open, but will be sealed when the panels begin to expand at higher temperatures.
    The panes may for Instance b® designed to withstand jet fires {gas fire) of 3SG: k / Wra® of heat flux, suggesting temperatures considerably exceeding 130 {PC,> The: panels have been tested for hydrocarbon fires with radiation heat of 11Q0 ° G.
