What should the initial survey of equipment class 2 and 3 DP vessels include?

The initial survey of equipment for class 2 and 3 DP vessels should indeed include a complete survey of the DP system and FMEA (Failure Mode and Effects Analysis) proving trials. This is essential because both class 2 and class 3 DP systems require a higher level of reliability and operational integrity due to their reliance on automated systems for maintaining position during various maritime operations.

Conducting a survey of the DP system is critical, as it ensures that the dynamic positioning system is functioning as designed and meets the necessary standards. Additionally, FMEA proving trials are important because they assess how the DP system performs under various fault scenarios, verifying that the system can handle potential failures without loss of position or control. Through these assessments, operators gain confidence in the DP system's resilience and safety, which is particularly vital for operations in challenging environments or where high stakes are involved.

Assessing crew competence, inspecting on-deck equipment, and documenting previous failures are also important aspects of DP vessel operations but do not encompass the comprehensive evaluation of the DP system itself which is crucial for the initial survey of such high-class vessels. Focusing on the DP system and its failure modes directly targets the vessel's operational capabilities and risk management, aligning with the stringent safety and performance requirements mandated
