The Risk Assessor Software (risk@assessor) is a structured risk assessment program for ship’s operation covering operational, accident, security and environmental risks with a unified approach. RAP considers risk assessment as an endless procedure utilizing business learning mechanisms based on industry and company previous experiences.
An integration approach of hazardous processes risk estimation with evaluation of hazardous events consequences is provided to support Risk Assessor to estimate risks with accuracy (according to the Code of Safe Working Practices for Merchant Seamen published by MCA, which is based on BS 8800 standard) and Risk Manager to implement plan of actions to reduce the consequences or the probability of occurrence (Risk management definition BS 4778).
RAP combines risk assessment with hazardous events analysis based on the following model:
A. Definitions and relationships
the source or a situation with a potential for harm in terms of human injury or damage to property, damage to environment or a combination of these.
Hazard & (lack of control | control failure)
Hazardous event & consequences
Any eventual activity defined as operational :company controlled (procedural, emergency, ad hoc) scenarios externally initiated: security vulnerability aspect having environmental impacts (operational or built-in)
The relation between risk assessment and accident analysis is based on hazard the elementary unit of risk theory according to the formula
SRA Hazard <=> Cause in accident analysis
Another one-to-one link that may be established is
SRA <=> Particular accident event
B. Functional specifications
Shipboard operations (procedurals, emergency or ad-hoc ships-controlled processes), possible non-controlled threats (scenarios) and aspects concerning environment are objects with risks. Risks must be identified and classified systematically before any risk assessment in order to support risk management. A hierarchical tree structure risk identifiers library must be implemented according to company’s risk management policy.
Any assessed operation may have more impacts regarding human health, security vulnerability, ship operations, or environmental contamination and consequently more than one risk assessments.
The following functional specifications and relationships are supported:
Any operation may have more than one a types and risk assessments utilizing the corresponding risk matrix table
Any operation assessment type evaluates the risk for one or more hazards
Assessment types may be classified to subtypes
Any operation may linked with general controls, references and attachments
Any accident may be linked to one operation
Hazards, controls and causes are classified asRisk may be assessed for more than assessors
PF (personal factors),
JF (Job factors),
UC (Unsafe conditions),
UA (Unsafe acts), and
R: Root (plan, compliance, Standard).
Risk assessment history must be recorded.
C. System ready for use
Danaos@ssessor is ready for use providing a standard operations library as well as a detailed libraries for hazards (=causes) per type. Hereafter with minor changes (if required) the system may be immediately alive.
D. Risk assessment, Events, Risk management
The consequences of any hazardous event (accident, incident) in terms of its consequences are quantified. The related operation risk assessment may be reevaluated. Additional control may be suggested and risk assessment attributes (consequences, frequency) should be reviewed.
E. The system structure
In the following diagram, the internal structure of the system is presented. The architecture enables the link between the assessments and the accident that was occurred and therefore supports the risk management.
F. Presentation level
Risk assessments are consolidated and presented in a content form. A typical presentation with filtering capabilities is shown above. For example the percentage of operations assessed as substantial by a given assessor or all assessors’ and many other answers satisfying criteria combination will be provided. For support risk management a frequency and severity statistical report per hazard is provided.
