Kerwin, PE  \nHow To Read Shipbuilding Drawings (Part 2) A SunCam online continuing education course  \n442.pdf  \nAs stated in Part 1 of “How To Read Shipbuilding Drawings”, ship design generally proceeds in three phases: Preliminary Design, Contract Design, and Construction Detail Design. Part 1 dealt with the Preliminary drawings; these show a minimum of detail, but enough to show the feasibility of the ship to meet the client’s requirements as a concept.  \nThe Contract phase of design is a combination of refinement of the Preliminary drawings, compromise in many areas to make everything work together, and addition of further details. It isan extensive set of plans and calculation when compared to the Preliminary stage of design. Naval Architecture has been called “The World’s Greatest Compromise” because of the myriad of things in a ship that compete for space, function, accessibility, cost, and efficiency of operation. In fact, successful Naval Architecture is a bit like conducting a symphony-the experienced Conductor makes beautiful music out of the many competing instruments; the inexperienced Conductor gets noise rather than music and often blows his or her budget when half-way through the project. The author has been called in to make music out of the owner’s self-led noisy project many times, usually with success. It is just amazing how many successful business owners that are inexperienced in marine design think that making a successful ship is simpler than designing a house or creating the unrelated business that made them wealthy.  \nThe purpose of the Contract design phase is threefold: to produce a set of drawings for the ship that harmoniously work together, to make a suitable information package for a shipyard to develop an accurate price quote from, and to produce the drawings that show that the design meets Classification Society and/or Coast Guard or Flag State requirements if the vessel is to be regulated as such. In the case of the latter, each of these entities publish books of regulations and/or design guides that must be followed in order to meet a minimum standard of design and construction that they will put their stamp of approval on. For the Classification Societies, they certify the insurable risk that is undertaken by the insurance companies; The Coast Guard or Flag State requirements (which a Coast Guard may be the enforcer of) are mostly concerned with the inspection, safety and manning aspects of the vessel, and quite often defer the inspection of structure and systems to the Classification Societies on newly constructed vessels.  \nGlossary-more extensive than Part 1:  \n• Aft-the direction toward the back end of the ship. Aft is an abbreviation for “after” and the two are used interchangeably in nautical terminology.  \n• Aft Perpendicular (AP)-Generally where the rudder stock is located no matter ifa structural frame is there or not. In the wooden ships of the past, this was where the rudder was hung on the ship, and it is also where ships in countries other than the U.S. often began the erection of the frames.  \n• Azipod-a propulsion thruster, often in a nozzle, that can rotate 360 degrees, thus precluding the need for a rudder. They are either electrically or mechanically powered.  \n• Amidships or Midships-the halfway point of the length of the Design Waterline (DWL) .  \n 442.pdf How To Read Shipbuilding Drawings (Part 2)  \nA SunCam online continuing education course  \n• Ballast-solid weights and/or liquid weight carried as extra weight in the bottom of the hull to improve the stability and trim of a vessel.  \n• Beam-the transverse structural member that supports a deck.  \n• Bilge-the lower edge and bottom of the hull. On the inside of the hull where there is not a tank, condensation and oily water may collect here.
