The Engineering Operational Sequencing System (EOSS) sets policies and procedures for the safe operation of a ship’s engineering plant, boat drills, rescue, etc.

Emergency Bills - Provide and organize prescribed procedures and assign responsibilities for controlling the effects of a major emergency or disaster suffered by the ship, such as man overboard, assist another ship when dead in the water, crash on the flight deck, or collision at sea.

Special Bills - Assign responsibility for and promulgate procedures for defense against sneak/swimmer attack, evacuating civilians, prisoners of war, troop lifts, etc.

Shipboard Procedures - Provide for standard routines for in port and at sea evolutions, such as UNREP, VERTREP, etc.

Ship's Regulations - Created to supplement and amplify those regulations contained in the SORM. The Chief of Naval Operations (CNO) sets the guidelines.
