Upon losing power, how long until a 13-man duty section is required?

When considering the requirements for watchstanding and duty sections after a loss of power, it’s essential to understand the operational protocols that ensure the safety and functionality of the vessel in such situations. In this context, a 13-man duty section is typically necessary after a certain time frame to ensure that sufficient personnel are available to manage critical operations and respond to any emergencies that may arise following a power loss.

The correct time frame in this scenario is 4 hours. This period allows sufficient time for the initial contingency response to stabilize the situation and assess the need for additional personnel. If power restoration does not occur within this 4-hour window, then a broader duty section becomes essential to maintain operational readiness and ensure all critical functions are effectively managed.

Additionally, anticipating the need for a larger duty section reflects the understanding that prolonged periods without power can complicate operations, necessitating a more robust team to handle potential challenges, including navigation, communication, and safety protocols.
