Dynamic vs Static Risk Assessment

  • Static risk assessment:
  • Non-operational
  • Does not focus on one operation, but covers

many ship movements in an area

  • Focuses on a wide time period
  • Proactive – generally conducted during the

planning phase

  • Probabilistic
  • More ‘controllable’ parameters that can be

changed

  • Low certainty about information
  • High availability of time & resources
  • Outcomes directly effect dynamic risk

assessment conducted during an operation

  • Dynamic risk assessment:
  • Operational
  • Generally focuses on one single operation
  • Focuses on a specific time period during the
  • perational phase of a system
  • Reactive – usually conducted during an on-

going operation

  • More deterministic than probabilistic
  • Either the consequences of an event are known

and/or the probability of the event is 1 or 0

  • Less ‘controllable’ parameters
  • The few ‘controllable’ operational parameters

(e.g. ship speed, rudder angle) may be used to quantify the risk in a scenario

  • High level of certainty
  • Low availability of time & resources

Static Risk Assessment

  • Sophisticated NRA frameworks/models already exist (Mehdi & Schröder-Hinrichs 2016)
  • Significant literature on contact, collision, grounding models
  • E.g. of previous work includes NRA models for bridges, quays, oil platforms

Static Risk Assessment

  • Consequence model selection was partially based on literature review & surveys
  • Included a comprehensive review of 50+ contemporary damage assessment models
  • Presented at Intl. Conference on Ships & Offshore Structures (ICSOS) 2016

Dynamic Risk Assessment

  • Why: lack of communication between operational & non-
  • perational maritime users
  • Survey of 122 seafarers shows 104 are unaware of any NRA

studies around OREIs

  • Results of a typical NRA often ‘meaningless’ for seafarers
  • Exception: if a risk-control option is integrated as a result of the NRA

that influences maritime operations

  • What: dynamic risk model that can be integrated as a

decision support system

  • Based on ship manoeuvrability & hydrodynamics
  • Relates the probability of an accident to the safe manoeuvring area

available to a ship

  • Initially developed for maritime collision avoidance
  • Developed from the principles for ACAS/TCAS used in the

aviation industry

Dynamic Risk Decision Support System: Future Work

  • Several potential future

developments:

  • Incorporate drift envelope

calculations

  • Integration with AIS data (variant

already been demonstrated successfully by Nakano & Hasagawa in 2012)

  • Potential integration of

consequence assessment based

  • n ship speed & rudder angle at

time of collision, contact or grounding

  • Integration with KPIs?

Improving Input Data for Risk Assessment Processes

  • MaRiSa Simulator Lab:
  • DNV-GL certified, multiple simulators:
  • Desktop ship handling

– Basic navigational equipment as specified by SOLAS – Internal Communication – e.g. – engine room to bridge – External Communication – e.g. – VTS

  • Safety & Security Training

– Virtual-reality – Simulates on-board accidents

  • HECSALV

– Damage Stability simulator

  • Manoeuvring station

– Predictive ship manoeuvres

  • Engine room simulator
  • SenseFloor to track movement on bridge
