9. 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.

10. b. Forecastle • foremostpartoftheupperdeck • usuallyraisedabovethemaindeck

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

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

13. e. Upperhold / Lowerhold • spacesthatcontainthecargoes

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

15. g. Chainlocker • storagefor anchorchain

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

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

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

19. 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

20. k. Steeringmachinery • givesthe power for movingtherudder

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

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