Hazard Identification & Risk Assessment

The process for identifying hazards, analysing and treating risks is identified in the diagram. The steps in the risk assessment process are identified as;

  • Selection of competent persons
  • Hazard Identification
  • Analysis of the risk
  • Evaluation of Raw Risk
  • Treat the Risk
  • Evaluation of Residual Risk

The 5 x 5 Risk Matrix

Measuring Risk

The objective of the risk assessment is to decide if the risk for a particular hazard is acceptable or not for people, environment and assets. The Matrix is used to quantify the risk. Unacceptable risks shall be eliminated or reduced to as low as reasonably practicable (ALARP).

This is the Magseis Risk Assessment Matrix which is used to quantify risk within the organisation

FRM-HSE-001-Risk Assessment Matrix


The Hierarchy of Risk Controls

Risk Control

Magseis work to reduce Risk to ALARP

  • For each hazard, define controls to reduce the risk to an acceptable level using the hierarchy of controls
  • Assign a designated person for the implementation of controls
  • If the risk is quantified as HIGH then the operation must not proceed. Control measures must be implemented or the operation halted permanently
  • If the risk is quantified as MEDIUM then operation may proceed. Consideration of further control measures may be necessary to reduce the risk ALARP. Manage for continuous improvement
  • If the risk is quantified as LOW then the operation can proceed. Risk control measures are sufficient. Manage for continuous improvement
  • Risk assess all proposed controls to ensure that new hazards are not introduced
  • Re-assess the risk when all controls are in place.
  • The risk remaining when all controls are in place is the residual risk.

Hierarchy of controls


Eliminate the hazard

remove it from the workplace


Substitute the hazard

substitute a substance, method or material to reduce the risk or the hazard.


Isolate or enclose the hazard


separate the hazard from the workplace/worker, e.g.

Chemical store room kept locked except to an authorised person Lock out procedures on faulty equipment.

Appropriate guarding for machinery.


Use engineering solutions

modify existing machinery or plant or purchase different machinery or plant


Administrative Procedures


develop work methods to reduce the conditions of risk, e.g.

Written Safe Work Procedures

Job rotation to restrict hours worked on difficult jobs

Staff trained in the correct operating procedures.



Use Personal Protective Equipment (PPE)


this should only be used as a last resort to deal with the hazard, where the hazard cannot be removed or reduced by any other means, e.g.:-

Handling of chemicals – gloves, safety glasses, aprons.

Protecting eyes from flying particles.

Protecting feet – safety boots.


Conducting HAZIDs & Risk Assessments

Conducting Hazard Identification and Risk Assessments

Routine Operational Risk


The team shall consist of a minimum of 2 appropriate operational field and shore based operational personnel

Project Risk Assessment

The team leader shall be the Vessel Manager/Project Manager.

The team shall consist of the leader and at least 2 appropriate project or operational personnel

Stand Alone Risk Assessments

The team shall consist of a minimum of 2 appropriate operational field/ shore based operational personnel

The hazard identification and risk assessment team shall consist of competent members of staff under the direction of an assigned competent person. The line manager shall assess the level of competency required and decide if external specialists are needed to complement the team.

HAZID Instructions\tips

Hazard Identification (HAZID)

Input to the HAZID

The Context

Identify Hazards

The following input should be used during the hazard identification process:

  • Magseis and Industry past incident/accident records to see what happened and whether the incident/accident could reoccur
  • Employees consulted to find out what they consider are safety issues
  • The work areas or work sites should be subject to inspection to identify hazards
  • Equipment manufacturer’s instructions, Material Safety Data Sheets, and maintenance records are reviewed to ensure that controls are suitable and sufficient

Consider the workplace and / or activity being assessed by identifying:

  • location, work processes, practices, activities and tasks that will be analysed in the risk management process and the steps involved;
  • the people involved in carrying out those work processes and in what capacity;
  • whether the people involved are sufficiently competent / skilled / experienced:
  • what items or plant and / or tool are used.

Use the brainstorming technique, and follow the step-by-step process below:

  1. Clearly define the scope of the HAZID (the equipment, area, operations included) and systematically group the work activities. For each work activity identify potential hazards. Give a short description of the hazard and when it is present. Use the “what-if” method of questioning.
  2. For each hazard, identify consequences and escalation factors if the hazard is realised into an incident. Ask your self “What could happen?” to identify associated consequences and “Why did it happen?” to identify escalation factors.
  3. Give references to documentation that are relevant for the work activity. This includes internal procedures and work instructions as well as external guidelines, standards and legislations.

Risk Assessment Tips

Risk Assessment

The team shall make a risk assessment for each hazard identified to determine:


  • the likelihood of those consequences arising
  • the severity of the consequences.
  • the nature of possible consequences
  • effectiveness of existing control measures
  • whether additional control measures are required


Emphasis shall be given to risks that present the highest severity. Risks that could generate catastrophic consequences, albeit infrequently, shall be given higher priority than those risks that create only small losses.


Hazard documentation headings





Task Risk Assessments (TRA)


The objective of the TRA is to identify hazards and define control measures to reduce or eliminate the risk for routine and non-routine detailed work activities.

  • Non routine activities for which a safe system of work does not exist require a TRA to be completed before the activity starts.


  • Routine work activities have documented safe systems of work (procedure/work instruction). There is a TRA for each procedure/instruction breaking the activity down into steps, defining the hazards and controls required for each job step.


A TRA is not required if a task is low risk. For some low risk tasks, an individual’s competency, skills, training and experience are sufficient that a formal recorded risk assessment is not required each time the task is performed. Examples are walking up and down stairs or taking a reading from unrestricted areas of a plant. In all cases, the individual must consider the associated hazard and be aware of change.


The TRA’s shall be used as the basis for the toolbox talk prior to the task starting.



The TRA Team


The team TRA team shall consist of all personnel involved in the task, under the direction of an assigned competent person.


The line manager shall assess the level of competency required based upon the complexity of the task and the level of risk likely to be present, and decide if external specialists are needed to complement or lead the team.



The TRA Process


1. Break the task down into a sequence of job steps

2. Identify Potential Hazards associated with each step and their effects

3. Use the Risk Assessment Matrix to quantify the risk

4. For each control assign a responsible person


The TRA Approval Process


  • TRAs associated with routine tasks documented by procedures and work instructions shall initially be approved onboard by the department head or Party Manager, and forwarded to the owner of the procedure/instruction they are connected to (normally the respective technical department manager ashore), who is responsible for final review and publishing.
  • TRAs associated with non routine tasks that are carried out on board the vessel shall be approved by the department head or Party Manager.




It is necessary to manage the change process as both permanent and temporary changes to equipment, processes, materials and/or people may have significant implications on the quality, health, safety or environmental impacts of a task or operation.


Management of change is a process intended to

  • Assure no unintended hazards are introduced
  • Assure risks are properly evaluated & minimized
  • Keep associated information current

instructions and risk assessments,

Technical information, training, mechanical integrity,

Project plans

  • Be completed before changes are implemented







The Management of Change (MOC) Process


The process follows the below steps;


  1. Identification of a change
  3. Assessment of the risk (quality, health, safety and environmental)
  5. Proposal of new controls to ensure the potential cannot be realised
  7. Approval of the change and controls by a manager at least 1 level above
  9. Implementation of the change and controls
  11. Review and monitoring


When is a MOC Required?


Not all changes require the full formal Management of Change process, but all changes must be evaluated for the new risk following the proposed change (ie a risk assessment). The formality of that risk assessment should be proportional to the level of potential risk.


Changes that require a formal Management of Change are;

  • Personnel
  • Experience/competence
  • Equipment
  • Materials or substances
  • Processes
  • Procedures
  • Work environment
  • Law, legislation or other applicable requirement



  • Any use of the FRC for personnel transfers


If in doubt about what level of MOC management is required, ask your line manager!


Management of Change Examples


  1. Change the type of rope used in a routine operation.


No; However a risk assessment should be completed to ensure the new type of rope will not introduce a new hazard (i.e. recoil if it snaps)


2. New Captain is coming onboard


Yes; he is a personnel change and responsible for the QHSE for the Maritime crew


3. Part of the robot system is not working properly a it is necessary to do one section by hand


No; A task risk assessment and instruction will be in place for manual tasks. Just a tool box talk to ensure that all involved are aware what parts of the process are being done manually



4. Example














How to complete an MOC


Assessment of the risk


Assessment of the quality, health, safety or environmental impacts of that change must be performed.


For significant change this shall be done through a formal risk assessment process using INS-HSE-001 Hazard Identification Risk Assessment and control.




Proposal of new controls


The assessment of risk phase will identify whether the risk is acceptable, or whether new controls must be implemented.


New controls shall be defined and persons responsible for their implementation agreed such that the residual risk is acceptable.




Approval of the change and controls


Once the risk assessment is complete, the proposer shall complete FRM-HSE-015 Management of Change Approval Form.



Completed MOC form


The completed form shall be reviewed and recorded in Insite. The change is approved by the relevant approving manager.


The approving manager signs to state that he/she believes the operation is safe to go ahead with the proposed controls in place, and that all quality, health, safety and environmental risks are controlled to an acceptable level.

Level of Change

Approval Authority

Temporary change in operations or personnel at the local site which can be controlled by minor alterations to work practices and when there is no significant increase in risk to personnel, equipment or the environment.

Department manager (for a vessel, Party Manager and Master)


Temporary or permanent change in operations or personnel where there could be an increase in risk to personnel, equipment or the environment.

Manager 1 level up from the department manager (for a vessel, Vessel Manager)

Temporary or permanent change in operations or personnel where there could be significant increase in risk to personnel, equipment or the environment.



Implementation and monitoring of MOC


Implementation of the change and controls

  • The proposer of the change shall oversee its implementation. This will often start with a toolbox talk to ensure that all personnel involved in the change and personnel who will be affected by the change are informed.


  • Before the operation continues with the change implemented, the manager approving the change shall confirm that all mitigation measures are in place

Review and monitoring

  • The proposer of the change shall monitor the progress of the change and the effectiveness of the controls.


  • For temporary changes the approving manager shall verify that the change has reverted within the time frame specified in the management of change form.
  • At the end of the activity or task, changes shall be reviewed with feedback into updates of the safe systems of work.
