What does NSTM CH 631 focus on?

NSTM CH 631 primarily focuses on the preservation of ships. This chapter provides detailed guidance on the maintenance and protection of both the structural and functional aspects of a ship to ensure its longevity and operational effectiveness. It covers various topics related to surface preparation, coating application, and the preservation methods crucial for preventing corrosion and wear, which are fundamental to maintaining the integrity and safety of naval vessels.

While preservation of ship decks is a component of overall ship preservation, the key emphasis of NSTM CH 631 encompasses a broader range of preservation practices beyond just decks. Equipment maintenance schedules are important but are typically addressed in other documentation, as are fuel conservation techniques, which fall outside the primary scope of NSTM CH 631. This underscores why the preservation of ships as a whole is the correct context for this chapter.
