Which NSTM chapter covers fuel systems?

The correct choice is that Chapter 541 of the Naval Ship’s Technical Manual (NSTM) deals specifically with fuel systems. This chapter provides detailed standards and protocols for the operation, maintenance, and safety of fuel systems onboard naval vessels. It is essential for personnel involved in handling, transferring, and managing fuel, as it ensures compliance with technical requirements and safe practices.

In broader terms, fuel systems are critical for the operation of a ship, as they supply the necessary energy for various systems, including propulsion and auxiliary operations. Understanding the guidelines in Chapter 541 is crucial for maintaining operational readiness and ensuring safety while managing fuel systems. The other chapters mentioned do not focus on fuel systems; rather, they cover related but different aspects of naval operations and other systems, which is why they are not the correct answers.
