GUIDANCE OF DP OPERATOR MANUALS AND EMERGENCY RESPONSE ACTION: DP OPERATOR MANUALS AND EMERGENCY RESPONSE ACTIONS: – Manuals and Emergency response actions should be reviewed to assess whether response to unwanted thrust is addressed with an adequate level of detail in procedures to aid identification and response, including: Set up of screens and other user interfaces. Recognition of, and response required, to alarms and indicators. Immediate response and communication protocols to limit consequence of failure. Emphasis for immediate response explicitly stated. NOTEs: Identify and document (DP Operations Manual) the means by which unwanted thrust is detected by the DP control system and the means by which the DP operator is alerted to the situation (e.g. prediction errors, set point feedback error, thruster control warnings). Identify the optimum set up of graphic user interfaces (e.g. pages, windows of the DP control / vessel control systems) which will give the DP operator prompt and clear warning of unwanted thrust. Identify and document (in DP Operations Manual, Emergency Procedures Manual as appropriate) the actions to be taken by the DP Operator on recognizing unwanted thrust in order to prevent loss of position. Document (DP Operations Manual) the procedures in place to ensure that all DPOs are aware of the potential for unwanted thrust, the warnings and indications specific to that DP control system and thruster system, and the actions to be taken in the event of unwanted thrust (e.g. activate emergency-stop). TRAINING DRILLS AND EXERCISES Vessel specific training will be developed, provided and documented for personnel operating the DP and Thruster Control systems. Documented familiarization and demonstration of response at drills and exercise. to be demonstrated if requested - Responses to be timed. ‘Touch Drills’ NOTE: DPOs should actively participate in practical training (live drills and touch drills as appropriate) for such a scenario. Such training and familiarization should be recorded. ASOG IMPLEMENTATION ASOGs (or equivalent e.g. WSOG, WSOC, ASOP etc.) to have clear statements in title block addressing: Vulnerability. Set up of screens (and other GUI) for rapid recognition of unwanted thrust. Requirements for documented drills and exercises. Configuration section and Addendum to Check List to contain specific verbiage addressing the above.
