Quick-acting Hatches Passage between spaces on DIFFERENT levels Most are water-tight boundariesCompartment Numbering: Compartment Numbering System used for ships built after 1949 4 main parts Deck Frame Compartment Use ex: 5 – 32 – 0 – E Deck Frame Compartment UseCompartment Numbering: Compartment Numbering Deck: Meaning: “Space is located on this deck” Upper levels are 01,02… successively from main Main deck is 1 Lower decks are 2,3,4… successively from mainCompartment Numbering: Compartment Numbering Frame: Meaning: “Forward boundary of compartment is on or immediately aft of this frame number” Sequential number given to transverse frames fore to aftCompartment Numbering: Compartment Numbering Compartment: Indicates position of compartment relative to centerline Centerline compartments are “0” Numbers follow in succession from centerline outboard Even numbers for Port side (2,4,6, …) Odd numbers for Starboard side (1,3,5, …) … 6 4 2 0 1 3 5 … Port Centerline StarboardCompartment Numbering: Compartment Numbering Use: Letter that designates primary use of the space Examples “A”: Supply & Storage “C”: Control (ship control or fire control) “E”: Engineering “F”: Fuel tank “L”: Living “M”: Ammunition “T”: Trunk “V”: Void “W”: Water tank Submarine Design: Submarine Design Hull (made of HY-80 or HY-90 steel) Watertight envelope designed to resist submergence pressure at CRUSH DEPTH Inner hull (pressure hull) Outer hull (non-pressure hull)Submarine Design: Submarine Design Structural Members Similar to surface ship but rounded for submarine hull shape and THICKER All levels have expansion joints (varying submergence pressures)Piping & Valve Numbering Systems: Piping & Valve Numbering Systems White Yellow Purple Dark Gray Light Gray/Tan Blue Light Blue Orange Steam Oil JP-5 HP Air LP Air Chillwater Feedwater Hydraulics Numbering system for valves similar to that for compartments (ie: MS-1, MS-2, etc.)Questions, Comments, Concerns?: Questions, Comments, Concerns?
