2.3.14 Requirements for cold starting arrangements of floating offshore installations shall be especially determined depending on project specific assessment of the safety hazards involved. 2.3.15 The performance and capacity of auxiliary systems shall be adapted to the needs of the machinery installations served. 2.4 Failure effects 2.4.1 In the event of failure, components and systems shall enter the least hazardous of the possible failure states with regard to machinery, personnel and environment. 2.4.2 The probability that failure in a component causes damage or failure to other components, shall be acceptably low. 2.4.3 Failure of one component in a system arranged as part of the designed redundancy shall not lead to failure or damage to backup or parallel components or systems. 2.5 Component design 2.5.1 Where no specific requirements are given in these standards regarding dimensioning and choice of materials, generally recognised standards and engineering principles shall be applied. 2.5.2 If acceptable accuracy cannot be obtained by strength calculations, special tests for the determination of the strength of the design may be required. 2.5.3 When it is of essential significance for the safety of the unit or installation that the function of a component is maintained as long as possible in the event of fire, materials with high heat resistance shall be used. 2.5.4 Materials with low heat resistance shall not be used in components where fire may cause outflow of flammable or health hazardous fluids, flooding of any watertight compartment or destruction of watertight integrity. Guidance note: Materials with high heat resistance are materials having a melting point greater than 925°C. Materials with low heat resistance are all other materials. Deviations from the above requirement will be subject to special considerations. ---e-n-d---o-f---g-u-i-d-a-n-c-e---n-o-t-e--- 3 Personnel protection Machinery, boilers and associated piping systems shall be so installed and protected as to reduce to a minimum any danger to persons onboard, due regard being paid to moving parts, hot surfaces and other hazards.
