  7. a. Upperdeck or maindeck • The principal deck of a vessel; in some ships the highest deck of the hull, usually but not always the weather deck; in sailing warships often a deck under the upper deck.

  8. b. Forecastle • foremostpartoftheupperdeck • usuallyraisedabovethemaindeck

  9. c. Tweendeck • spacebetweendecks – intermediatedeck • dividesthevesselinto separate holds

  10. d. Tanktop • insidebottomofthevessel • the plating forming the inner bottom of a ship hull

  11. e. Upperhold / Lowerhold • spacesthatcontainthecargoes

  12. f. Peak tank • foremostandaftermostspacesofthevessel • serve as storagespaces for ballastwater • capableofabsorbingpartoftheimpactforcesthat are releasedincaseof a collision

  13. g. Chainlocker • storagefor anchorchain

  14. h. Bosun’s locker • = Boatswain’s locker • serves as storage for ropes, paintanddunnage

  15. i. Collisionbulkheads • foremost major watertightbulkhead • preventthevesselfromfloodingincaseofcollisionwithanothervessel • fireproof

  16. j. Engineroom • = machineryspace • watertightcompartment • situatedovertheafterpeaktank • housesthemainandauxiliarymachinery

  17. j. Engineroom • on a large percentage of vesselsengine room is located near the bottom, and at the aft • usually comprises few compartments - this design maximizes the cargo carrying capacity of the vessel and situates the prime mover close to the propeller, minimizing equipment cost and problems posed from long shaft lines

  18. k. Steeringmachinery • givesthe power for movingtherudder

  19. l. Doublebottom • providesstrengthandstoragespace for fuel, lubricating oil, freshwater, salt (ballast) waterandpotablewater

  20. m. Cofferdams • emptyspaces / longitudinalandtransverseseparationsbetweentanks • preventleakingofliquidsfrom one doublebottom tank intoanother

  21. n. Superstructure • accommodation for thecrewandpassengers • messroom, galley, pantry
