is a control system based on SIL certified PLC, used for the boilers and heaters burner management.

The principal purposes of BMS are:
• To protect against startup when unsafe conditions exist.
• To protect against unsafe operating conditions and admission of improper quantities of fuel to the furnace.
• To provide the operator with status information.
• To initiate a safe operating condition or shutdown procedure if an unsafe condition exists.

An effective BMS should provide everything to monitor, control, diagnose, and maintain the various aspects of fuel burning equipment, including the ability to initiate a safe operating condition or shutdown procedure if an unsafe condition exists.

A number of major standards currently or previously played a significant role in determining the safety requirements of a BMS, including NFPA 85, NFPA 86, NFPA 87, OSHA 29 (CFR 1910.119), FM 7605, ISA S84.01, IEC61508, and IEC 61511.
Of these, the most influential have been those from the
National Fire Protection Agency (NFPA).

SIL certified PLC, is a countermeasure crucial in any hazardous plants such as oil and gas plants and nuclear plants.

They are used to protect human, industrial plant, and the
environment in case of the process going beyond the allowed control margins.

As the name suggests, these systems are not intended for controlling the process itself but rather protection.

Process control is performed by means of process control systems (PCS) and is interlocked by the safety systems so that immediate actions are taken should the process control systems fail.

is designed to protect the plant people and facilities from hazardous conditions, and is a part of the safety and control systems covering the overall plant control and monitoring requirements.

A Fire and Gas detection system is continuously monitoring all areas for abnormal conditions.

The F&G System can detect hazardous events, initiate timely actions, and alert personnel in order to minimise the consequences of a critical event.

The F&G System shall achieve these objectives by:
• Detecting at an early stage, the presence of flammable gas
• Detecting at an early stage, the liquid spill (LPG and LNG)
• Detecting incipient fire and the presence of fire
• Providing automatic and/or facilities for manual activation of the fire protection system as required
• Initiating environmental changes to keep liquids below their flash point
• Initiating signals, both audible and visible as required, to warn of the detected hazards
• Initiating automatic shutdown of equipment and ventilation if 2 out of 2 or 2 out of 3 detectors are triggered
• Initiating the exhausting system
Actuating the automatic fire fighting systems.

an important safety consideration in the process industry is the prevention of loss of containment due to vessel or pipeline overpressure situations.

Loss of containment can have catastrophic effect to human life and the environment and also have a negative economic impact, due to production loss and maintenance costs.

Conventional design of pressure relief or safety valves are used as a primary mean of pressure protection on most applications.

However, with increased flow rate potentials into existing infrastructure, applications where pressure relief devices are impractical and increased environmental constraints, the use of HIPPS High Integrity pressure System) is widely becoming accepted as the ultimate protection system.

HIPPS is an independent Safety Instrumented reliable system that is designed with higher system integrity, according with established ANSI/ISA and IEC standards, than process shutdown and emergency shutdown systems.

The SIS standard are performance-based with the Safety Integrity Level SIL as the primary performance measurement.

The SIL represents the necessary risk reduction, as recognized in a user’s risk reduction analysis.

Each SIL level corresponds with a tolerable probability of failure on demand PFD) to all HIPPS devices from sensor through the logic solver and final elements.

In most cases, it is not acceptable for the HIPPS to trip and stop the plant operation due a single failure.

To increase the availability of the system redundant architecture can be designed.
