INDE 6332 ENGINEERING PROJECT MANAGEMENT Homework Project University of Houston Dept. of Industrial Engineering Houston, TX (713)

AGENDA l Project

PROJECT l A series of connected homework projects l Application of most of the concepts covered in class l You will be given time in class to coordinate project efforts l Each week your team will rotate project managers among the group members

PROJECT BACKGROUND l Conduct all the necessary project activities to build a one-off custom designed mid-sized cruising sailboat l Ultimately Determine n What type of sailboat project to undertake n Identify what components are needed n Identify what resources are needed n Determine the project plan including sequencing n Perform budget and cost estimation n Identify a means of monitoring the project progress n Etc. l Will need to use the Internet to perform project research

INITIAL PROJECT DESIGN DECISIONS l Size… l Rig design… l Hull material… l Hull design… l Propulsion… l Many other design decisions, but we have to draw the line somewhere

SIZE l Sailboats are measured by overall hull length and width (beam) l The longer the boat, the wider the beam l Every five feet, the effective volume doubles n Forty foot boats are actually twice as large as 35 foot boats l Popular sizes of these types of boats n 36, 38, 40, 42 l Bigger is more expensive to buy and cost more to maintain

RIG DESIGN l The rig consists of n The masts n The sails n Supporting wire stays l Designs in order of complexity n Sloop – 1 mast with one headsail and one mainsail n Cutter – 1 mast with two headsails and one mainsail n Ketch – 1st mast with one headsail and one mainsail, 2nd mast with mizzen sail l Flexibility under adverse conditions n Sloop < Cutter < ketch l Cost n Sloop < Cutter < Ketch

HULL MATERIAL l Fiberglass n Cheapest material and easiest to make n Blisters, but does not corrode n Easy to repair l Aluminum n Most costly material and most difficult to make n Does not blister, but can corrode n Difficult to repair l Steel n More costly material and more difficult to make n Heavy – can only build larger boats n Does not blister, but corrodes n Easy to repair

HULL DESIGN l Fin n Lighter weight n Lesser stability, more maneuverability n Poor protection against grounding l Modified Fin n Moderate weight n Intermediate stability and maneuverability n Some protection against grounding l Full Keel n Heaviest weight n Greater stability, less maneuverability n Most protection against grounding

HULL DESIGN FIN KEEL MODIFIED FIN AND SKEG FULL KEEL

PROPULSION l Most sailboats have diesel engines n Yanmar, Volvo, Perkins, Westerbeke, Vetus l HP n Appropriate for the boat size l Drive method n Shaft – more expensive to install cheaper to maintain n Sail drive – cheaper to install more expensive to maintain l Fuel tank size l Bigger diesel engines costs more and uses up more fuel
