Question
Site Information Located in a developing country and 100% owned by a major UK company listed on the London Stock Exchange with operations mainly in Western Europe, but has a global presence. The tank farm was built about 15 years ago by a small US operator and the current operator is a UK company who bought the assets and have operated it for the last two years with well-trained people from the local region. The country's HSE regulatory system is minimal: regulations tend to be prescriptive and mainly focused on occupational safety. The regulator is under resourced The tank farm stores a range of refined products: aviation fuel, gasoline for motor vehicles and fuel oil (diesel for vehicles and generators) There are 10 tanks each 18 m high x 15 m diameter. The tanks are bunded in pairs. Generally each tank is used to store a specific product but that can change depending on demand The tank farm has two shifts with 3 people on the night shift and 12 people on the day shift The tank farm is the only source of fuel products for a high value mining operation which is about 20 km away and located in a dense swampy forest. The tank farm products are exported using road tankers. The fuel is also used for local communities that support the mine. The mine is state owned and a critical source of income for the country ssumptions A number of assumptions will need to be made. Factors to consider: No fire and explosion or dispersion modelling has carried out. Where did the ignition take place? In general the ignition point will be the origin for the highest explosion over pressure which then dissipates with distance. If ignition occurs in the process plant then potentially it could have created equipment failures and secondary leaks; a typical worst case escalation However if the ignition occurred at the tank farm then we can assume that a . scenario overpressure occurred at the process plant. However, this would imply that the overpressure at the tank area is >200 mbar which would certainly cause collapse of some of the tanks and substantial loss of containment The control room is exposed to 200 mbar overpressure. We can assume this is within the elastic structural response range of the building and occupants are not injured. Other buildings may not be designed so well, and occupants in those buildings could be injured. No information is given about fire and gas detection, fire water, hazardous drainage systems or casualty treatment rooms. We can assume that these are not in place. However, because it is in a tropical rain forest it will have a storm water drainage which most likely drains into the river.
Explanation / Answer
A) Emergency incident
The ignition point will be the origin for the highest explosion over pressure which then dissipates with distances.
potential risks
Equipment failures and secondary leaks due to ignition occures at process plant .
Collapse of some of the tanks and substantial loss of containment due to overpressure of the tank area is greater then 200mbal.
B)Mitigation barriers
The control room is expected to 200 mbar overpresssure .The elastic structural response range of the building and occupants are not injured .
C)Pontential Threat
No fire and gas detection equipment is placed .
No hazardous drainage systems, treatments rooms.
D A muster point is a designated place or an area where all employees passengers or a large crowd assemble in case of an emergency in an installation ,building ,public place or a watercraft .It is also know as an emergency assembly point(EAP).
Ramsar wetlant presences neat to watercraft river ,so it could be the Emergency assemble Point(EAP).
2)Warehouse and workshop changed neat to watercraft river to be act as (EAP).
