Risk Management Made Easy

Purpose and objectives of this presentation:• To introduce the BowTieXP methodology and software

Introduction

HistoryThe exact origin of the bow tie methodology is unknown. The first scientific reference (that we are aware of) was in a publication of the University of Queensland, Australia in 1979.The Bow tie methodology matured in the early nineties when the Royal Dutch/Shell Group developed the technique as a result of the Piper Alpha disaster.Because of its background Bow ties have been traditionally associated with ‘major hazard’ risk analysis, often a bow tie file is referred to as a ‘safety case’

Introduction

Risk Evaluation and ManagementThere are many descriptions of risk management processes, but they all can be simplified into the following four underlying steps:

Introduction

Are people, environment or assets exposed to potential harm?What could go wrong?

What are the causes and consequences?How likely is it?How bad will it be?What is the risk?

Can the causes be eliminated?Is there a better way?How can it be prevented?How effective are the controls?

IDENTIFY

ASSESS

CONTROL

RECOVERCan the potential consequences be limited?What recovery measures are needed?Are recovery capabilities suitable and sufficient?

Introduction

Hazards are part of normal business

Unwanted Consequences

Consequences are the result of losing control

Bow tie characteristics

Increasingly popular• Both commercial and governmental organisations accept the BowtieXP

methodology as their standard for risk management• The number of risk managers using BowTieXP increases day by day• Consultancies worldwide offer BowTieXP related training and services• Regulators are enabled to audit effectively

Why is it called bowtie?

BowTie Method Explained

BowTieXP Explained

HazardThe potential to cause harm, including ill health and injury, damage to property, products or the environment, production losses or increased liabilities.

Top EventThe ‘release’ of the hazard. The initial consequence. What happens when control is lost.

Some examples of Hazards:• Driving vehicle• Stored materials• Working at height• Money transfers• Electrical systems

• Crowding• Working at night• Moving machinery• Construction work• System maintenance

Some examples of Top Events:• Loss of Containment• Structural Failure• Dropped Object• Loss of Control• Electrical Shock

• Falls to Same Level• Falls to Lower Level• Oxygen Deficiency• Loss of Separation• Contact

BowTieXP Explained

ThreatA possible cause that will potentially release a hazard and produce a Top Event.Some threats / potential causes

BowTieXP Explained

• Thermal - high temperature• Chemical – corrosion• Biological

• Bacteria• Marine growth

• Electrical - high voltage• Environmental Condition

• poor visibility• Flooding

• Human Factor - incompetence

BowTieXP Explained

ConsequenceAn event or chain of events that potentially results from the release of a hazard.Some examples of Consequences:• Reputational damage• Financial damage• Property damage• Production loss• Injuries / fatalities• Distressed personnel• Unemployment• Complaints

BowTieXP Explained

Threats and consequences need to be controlled

Control of Threats – Threat BarriersA protective measure put in place to prevent threats from releasing a hazard. Can be engineered / hardware or actions carried out by people.

Threat Barriers

BowTieXP Explained

Recovery Preparedness for Each ConsequenceAll technical, operational and organisational measures that limit the chain of consequences arising from a top event.

Some examples of Recovery Preparedness Measures:• Systems to Detect and Abate Incidents

• gas, fire & smoke alarms, ESD, deluge• Systems Intended to Protect the Safeguards

• fire & blast walls, protective coatings, drain systems• Operational Systems Intended for Emergency Management

• contingency plans, training, drills, clean up, restoration, medical treatment• Compensative measures

• re-stock fish, financial compensation

BowTieXP Explained

Threat barriers and recovery measures control the release of the hazard or reduce/prevent the

consequences

Escalation FactorsConditions that lead to increased risk by defeating or overriding barriers or recovery preparedness measures.

Escalation Factors, some examples:• Environmental Variations

• Extreme weather & tidal conditions• Loss of Services

• Hydraulics, electric power

BowTieXP Explained

Escalation Factor ControlsControls put in place to manage conditions that lead to increased risk due to loss of barriers or loss of recovery preparedness measures.
