Assessment Context

Contemporary ship operations face a converging set of safety and risk challenges that include increased reliance on dynamic positioning systems, persistent risk exposure in tanker operations, more frequent and severe extreme weather events, and the rapid uptake of alternative marine fuels driven by decarbonisation pressures. Flag states, classification societies, operators and charterers are under growing scrutiny to demonstrate that safety management systems and risk controls are robust, evidence based and aligned with recognised methodologies such as Formal Safety Assessment and structured qualitative or quantitative risk analysis. This assessment requires you to integrate these dimensions into a coherent and practice oriented risk analysis for a clearly defined operational scenario.

Assessment Task

Task Description

Prepare a 3,000–4,000 word risk analysis report that critically evaluates safety risks in a specified offshore or deep sea operation involving:

• Dynamic positioning operations

• Oil or chemical tanker risk exposure

• Extreme weather and environmental conditions

• The introduction or planned introduction of at least one alternative marine fuel, such as LNG, methanol, ammonia, hydrogen or biofuels

You must select one integrated operational scenario that credibly combines these elements. Suitable examples include:

• A DP shuttle tanker loading from an offshore FPSO in a harsh environment region

• A DP capable tanker conducting ship to ship transfer in a monsoon or cyclone prone area

• A product or chemical tanker bunkering alternative fuels at an exposed offshore or coastal terminal with DP support craft

• An offshore support vessel using alternative fuel while providing DP assistance to tanker operations near subsea infrastructure

Core Requirements

Your report must address the following elements in a structured and logically ordered manner.

i. Operational scenario definition

• Description of the vessel or vessels, cargo or fuel, operating location, environmental conditions and operational profile

• Summary of the applicable regulatory and guidance framework, such as IMO DP guidance, SOLAS, MARPOL, the ISM Code, ISGOTT, IMCA DP guidance and alternative fuel safety guidelines

ii. Hazard identification

• Identification of major hazards relating to DP system integrity, tanker operations, extreme weather exposure and the selected alternative fuel or fuels

• Use of an appropriate structure, such as a systems based breakdown or an operation based task analysis

iii. Risk analysis and evaluation

• Assessment of likelihood and consequence for the most significant hazards using a clearly presented risk matrix or other justified method

• Consideration of loss of position, collision or allision, cargo or fuel release, fire or explosion, personnel injury or fatality, and environmental damage

vi. Alternative fuels risk perspective

• Comparison of key risk characteristics of the selected alternative fuel or fuels with conventional marine fuels, including flash point, toxicity, dispersion behaviour and credible release scenarios

• Explanation of how alternative fuel adoption modifies the overall risk profile of the operation

vii. Risk reduction recommendations

• Proposal of prioritised and justified risk control options using the ALARP principle and, where appropriate, Formal Safety Assessment style reasoning

• Coverage of technical design, operational limits and procedures, training and human factors, and organisational governance

viii. Reflection on method and limitations

• Brief reflection on the strengths and limitations of the chosen risk analysis approach, including data availability and uncertainty

A DP shuttle tanker operating in a subarctic offshore field faces a clustered set of hazards that arise from interactions between position keeping systems, metocean extremes and hydrocarbon transfer operations rather than from a single technical failure. Loss of position events often originate in combinations of power system degradation, reduced position reference integrity and delayed human response to alarms, which may escalate rapidly when wind, wave and icing conditions push the vessel beyond its safe operating envelope. Where alternative fuels such as LNG or methanol are used, bunkering and fuel containment introduce additional low probability but high consequence scenarios that must be considered alongside DP and cargo transfer risks. A structured hazard identification process that links DP control loops, cargo systems, alternative fuel arrangements and weather limits enables operators to identify escalation pathways and apply targeted technical and procedural controls.

Guidance on qualitative risk assessment for alternative fuelled ships emphasises that many safety failures emerge from weak integration between technical systems and operational decision making rather than from design deficiencies alone. In DP supported tanker operations, this means that risk controls must align vessel capability, crew competence and real time operational limits in a coherent manner. Establishing clear decision thresholds for weather limits, fuel handling and DP degradation modes improves consistency in risk acceptance and supports defensible ALARP decisions across complex operations (Maritime Technologies Forum, 2021).
