Abstract

Exploration activities in general are carried out in remote areas of the planet like the middle of the jungle, in this sense the operation companies have to keep logistic bases where they store large quantities of flammable products (diesel, turbo and gasoline) in flexible containers (bladders) usually about 25,000 gallons capacity. These bladders store flammable and combustible liquids in temporary operations and are located in areas exposed to heavy rainfall, high solar radiation, environmentally sensitive, close to communities or archaeological zones. In case of fuel loss by a fire in the bladders, the replacement time is very high. The available area to place the bladders is also a limitation. In order to avoid the domino effect the bladders should be separated between each other.

Our case material of this paper is a logistic base which is located in the jungle of Peru, it is one hour forty five minutes by helicopter or two days by boat from the closer city, that base has the characteristic of temporary and its works like facility to the activities carried out in the exploration block; it needs to store 200,000 gallons of flammable fuel (diesel and turbo) to support exploration activities at an Exploration Block in the jungle of Peru twenty kilometers from Ecuador – Peru border. The products are stored in bladders of 25,000 gallons, in total there are 100,000 gallons of diesel and 100,000gls of turbo. The logistic base is located in an environmental sensitive area because it involves important waterways, primary and secondary forests, nearby communities, as well as a military base, which could be adversely affected in the event of an uncontrolled fire. The available area to place the bladders is limited which does not allow to distance them properly to avoid the domino effect. Also for environmental reasons and permits the 8 bladders must be located in the same pit.

In case of a "pool fire", it will be necessary to use large amounts of water and foam to smother it which, among other things, increases the risk of contamination of water resources near the area. It assed different alternatives to protect the pit, based on risk scenarios, the main issue to evaluate is the "pool fire", which can trigger a fire in all the bladders by the domino effect. To reduce risk, reduce investment in firefighting system and use the limited space available, it decided to investigate and define a passive protection system and the purchase of mobile firefighting systems, which can additionally be transferred to future projects.

The design of passive protection system must be able to protect the bladders in a case of fire in one bladder the other bladders must not get fire. On the other hand the firefighting system must extinguish the fire in less than 20 minutes and do not need a system of storage water.
