مهندس بترadopt the approach of providing simple, minimum facilities design and simplify process design;
minimise flammable and toxic inventories and the number of leak sources;
select more reliable equipment instead of using sparing
isolate spare or redundant equipment when not in use;
use high quality and reliable materials and equipment to minimise maintenance;
use one reliable instrument/equipment item instead of several less reliable ones;
pay particular attention to avoiding use of maintenance intensive equipment;
adopt a risk and reliability based maintenance strategy;
minimise maintenance visits in hazardous areas separating non-hazardous/hazardous equipment;
optimise equipment layouts with maximum use of natural ventilation;
segregate personnel from major hazards;
consider flow of personnel to and from worksite in relation to the major hazards;
replace hazardous materials and chemicals with less hazardous ones;
minimise the use of protective safety systems requiring high maintenance;
minimise number of ignition sources, such as fired heaters and hot surfaces.Platform Layout designed to minimize n° of people potentially involved in the running of the plant (POB = 10 operators), prevent escalation and allow escape and evacuation if necessary.
Main objectives of WELL-DESIGNED LAYOUT are:
minimizing possibility of hazardous accumulations of both liquids and gaseous hydrocarbon and providing for rapid removal of any accumulation which could occur;
minimizing ignition probability;
minimizing spread of flammable liquids/gases which may results in a hazardous event;
minimizing consequence of fire and explosions;
providing for adequate arrangement for escape and evacuation;
facilitating effective emergency response.
