Definitions
- the present invention relates to a security system on an installation in connection with hot work operation in a habitat, which results in heat generation, such as flames, sparks and the like, and where an overpressure of air is set up inside the habitat to prevent ingress of
- inflammable gases or combustible dust comprising systems for supply of electricity and overpressure air to the inside of the habitat, and also an alarm that can warn of irregularities and the like
- the safety system comprises at least one fan unit for providing air and said overpressure in the habitat and a number of detectors which can register parameters such as gases and pressure conditions adjacent to and/or inside the habitat, and where the security system is arranged to shut down
- a habitat means the same as a closed chamber, a utility tent, a house or the like where the object can be
- habitats are constructed from flame retardant cloth or aluminium or tin plates, adapted for the particular application case.
- the habitat can have a large number of different shapes, according to the specific objects of application. In the following, the tern habitat will be used for such closed room/chamber only.
- Habitats are used in conditions where it is forbidden to use open fire or carry out work that leads to a danger of fire or explosions, such as heat generation, sparks and the like from welding, grinding, cutting and/or
- sandblasting For example, typical tasks are when metal parts or pipes are to be welded together. This is particularly the case for offshore and onshore oil and gas installations where drilling for hydrocarbons is carried out and/or crude oil is produced.
- the at least one fan unit is placed outside the habitat and comprises a gas detector in the air intake of a fan, and a control device connected to the gas detector, arranged for shutting off supply of electricity to the heat generating equipment in the habitat and to release a water sprinkler system in the habitat, upon detection of inflammable gases or loss of overpressure.
- the fan unit can comprise or be connected to a fail safe gas controller arranged to control the at least one gas detector and to shut down the system in case of
- the water sprinkler system can be placed in or adjacent to a door, air lock or inlet sluice of the habitat, and arranged to provide a water curtain in the habitat.
- a water supply, an air supply and a power supply from the installation, and at least one alarm, at least one line for power to the equipment inside the habitat, and a line connected to a pressure gauge, is connected to the fan unit.
- a pressure measuring gauge which transmits a signal to a "control device” when it registers a pressure that is lower than a given value (necessary overpressure) . The electricity supply to the welding equipment and the like is then simultaneously shut off.
- Detector that sends a signal to the "control device” at detection of abnormal levels of gases, in particular inflammable gases.
- the habitat can be supplied with air from the compressed air system of the platform itself, or air driven fan or fan working on electricity.
- the habitat is set under overpressure in order to keep dangerous gases, vapour or dust out of the habitat.
- the system according to the invention can, as mentioned, be operated both with its own internal fan system for the generation of the overpressure air, or can utilise the installations own compressor system.
- FIG. 1 shows schematically an example of the security- system according to the invention.
- the habitat can, in a known way, comprise an inlet sluice or air lock.
- the sluice comprises
- the habitat is shown with reference number 10.
- the habitat 10 forms as mentioned a closed space to isolate the carrying out of heat generating tasks.
- a line 28 for compressed air connects the habitat 10 to a fan unit 12.
- the line can additionally supply compressed air from the installations own compressed air system, to maintain an inner overpressure in the habitat 10 at a given level in relation to the surroundings.
- a water supply 34 to the fan unit 12, it is further connected a water supply 34, an air supply 30 and a power supply 32, from for example the installation.
- Additional and optionally gas detectors 20 can be used, which can be placed outside or inside the habitat 10. These detectors can be connected via a line 20a to the fan unit 12, and used as previously known.
- an alarm 22 can be connected to the habitat 10 via a line 22a, and of course a line 24a connected to a power inlet 24 for supply of power to the equipment inside the habitat, and a line 26a connected to a pressure gauge 26.
- the fan unit 12 further comprises a fan 18 equipped with a gas detector 14 in or arranged adjacent to the air intake of the fan 18.
- the fan unit 12 also comprises a control device 16, which is arranged to control all the lines connected to the fan unit 12. Upon detection of inflammable gases by the gas detector 14, the control device 16 is arranged to shut down the power line 24a to the equipment in the habitat 10, and to activate the alarm 22 to emit a sound and/or light signal.
- the control device 16 is further arranged to open a valve 38 for releasing a water sprinkler system 36 in the habitat, where the water sprinkler system 36 can be placed anywhere in the habitat and/or it can be placed in or adjacent to a door or inlet " sluice of the habitat 10, and which is arranged to provide a water curtain in a certain area of the habitat.
- the water curtain will thus "kill” inflammable gas or dust that is combustible, and prevent ingress of said gas or dust in the habitat 10.
- the pressure gauge 26 Upon registration of loss of overpressure by the pressure gauge 26, the same actions will be effectuated.
- the water sprinkler system can for instance be of a type called Deluge fire sprinkler system, or any other suitable sprinkler system, and can be automatically released as disclosed previously or it can be released manually.
- the fan unit 12 can comprise or be connected to a fail safe gas controller arranged to control the at least one gas detector 14 and to shut down the system in case of irregularities.
- the fail safe gas controller can be implemented in the control device 16.
- the possibility of connecting together the systems shall be mentioned so that the installation' s own control system can monitor all the habitat functions, and then shut off the electricity supply when something abnormal arises in the habitat itself.
- the connection can, for example, be such that when faults occur in the -installation that result in special security measures being initiated, then the system also disconnects all electricity supply to the instruments and equipment that are running inside the habitat.
- the invention will find use in offshore and onshore oil installations, in refineries, within the chemical industry and at other plants where it is necessary with habitat solutions when heat generating tasks are to be carried out .
