Offshore facilities generators

In the ease of an offshore facility, electrical power is generally ge ated on site by engine- or turbine-driven generator sets using natural or diesel as fuel. Most installations are designed to handle the total e tri. 1 even if one generator is out of service. To minimize the siz st quipment, some facilities have a system to automatically f... 

In any plant there are certain obvious hazards, for example, fire hazard in shale shaker area of offshore facility or generator are hydrogen cooled generators in power plants. HAZID is not meant to identify such kinds of hazards only. There needs to be some realty and lateral thinking power while carrying out the study. Also there always exist certain chances of a hazard in a complex event, on account of a series of activities. In the study this can be revealed. These characteristics shall include but are not limited to the following ... 

In 1986 when the oil price crashed to 10 a barrel, operators began to look very hard at the requirements for offshore developments and novel slimline, reduced facilities platforms began to be considered. The reduced capital outlay and early production start up capability, coupled with the added flexibility, ensured that all companies now consider subsea systems as an important field development technique. Although the interest and investment in subsea systems increased dramatically, subsea systems still had to compete with the new generation of platforms, which were becoming lighter and cheaper. 

Cyclones (hurricanes/typhoons) develop over warm bodies of water and create high winds and thunderstorms. Many offshore oil and gas facilities, particularly in the Gulf of Mexico, are vulnerable to the effects of cyclones. Tropical storms and tropical depressions have the same causes as cyclones but generally do not generate such high winds—although they can create considerable rainfall. 

Offshore structures are relatively self-sufficient they provide electrical generators, water desalinators, sleeping facilities, communication stations, and modern amenities. Production platforms are connected by pipelines or floating storage units to onshore operations. Key process elements of oil and gas recovery include wellhead, production manifold, production separator, water injection pumps, gas compressors, glycol process to dry gas, oil and gas export metering, and main oil-line pumps. 

Offshore production platforms and drilling rigs are generally arranged into Safe and Hazardous Areas. The two areas should be separated from one another and may have physical barriers between them. The Safe Area will include accommodations, the control room, UPS (uninterruptible power supply), emergency power generation equipment, and nonhazardous platform utilities such as water and compressed air. The Hazardous Area contains the flare, derricks, gas compression, hydrocarbon separation, the wellhead, and drilling facilities.
