Preskriptiva lösningar för fiberarmerad polymerkompositer i handelsfartyg : En Litteraturstudie
In todays possibilities in using alternative material designs in the construction of ships there is a need for prescriptive regulations. Therefore this thesis was initiated to develop a draft on a part of a prescriptive regulation for Fiber Reinforced Polymers (FRP) on SOLAS – ships and to design simple but general regulations to avoid extensive Regulation – 17 analyses when making novel constructions.In “Safety of Life at Sea” (SOLAS) ships, all load bearing structures and A-class divisions must be constructed in steel or equivalent materials. With support of “Regulation – 17” an alternative material configuration can be approved if a risk assessment demonstrates that an equivalent safety is present. However a “Regulation 17 – analysis” tends to be quite extensive and is generally infeasible, therefore a smaller selective regulation is needed in each ships construction.The development of these new regulations was initiated by a literature study. Knowledge gained from this study paired with conclusions and experiences from earlier research studies and Regulation – 17 analyses were used to develop a draft for new regulations.In commercial ships, SOLAS class structural interchanges can be noted as follows: “A ” class divisions can be replaced by Fire Resisting Divisions – 60 minutes, further addressed as FRD – 60, if consisting of Fiber Reinforced Polymer structures with thermal insulation comparable to the “A” – class.“B” class divisions and lower requirements can be replaced by FRD – 30 minutes, further addressed as FRD – 30, if consisting of Fiber Reinforced Polymer structures with thermal insulation comparable to the “B” - class.At points of Joint between FRP constructions and Steel constructions the thermal conductivity must be analyzed so that a loss of time in fire resistance does not occur, due to the thermal conductivity of steel. These standards shall be to the satisfaction of the Administrations.Commercial passenger ships constructed mainly by Fiber Reinforced Polymers shall not have a traveling route ...
