**SBRCD Project**Operations Simulation**Simulation Description**• This simulation activity requires two class periods • Students work in groups of 4 • Each session can be completed within one class period (55 min.) • Students learn about the various departments by building a paper container ship.**Operation Simulation Schedule**Day 1: Shipyard Operations Day 2: Design Calculations**Day 1**Day 2**Material Flow**Information Flow Production Layout Plasma Cutting Bending Machine Supplier Welding**Day 1: Activities**• Instruction manual is provided to guide students in constructing the ship • Three departments are involved in this simulation (excluding the Supplier) Teacher serves as the Supplier • Plasma Cutting Shop cuts the plates • Plate Shop bends the plates to form hull modules • Welding & Final Assembly Shop assembles the ship modules**Starboard**Stern Bow Port Bow : Front part of the ship Stern : Rear part of the ship Starboard : Right side of the ship Port : Left side of the ship Ship Terminology**Activity Involved in the Plasma Cutting Shop**• Receives steel plates from the supplier • Cuts the plates along the solid line • Sends the parts to the Plate Shop • All the parts are numbered in the order in which they have to be sent to the next department.**Bow Deck Plate – Cut Part**Stern Deck Plate – Cut Part**Activity Involved in the Plate Shop**• Receives steel plates from the Plasma cutting shop • Bends the parts along the dotted lines using the instructions given in the instruction sheet • Sends the parts to the welding shop**Bow – Bent Part**Bow Deck Plate – Bent Part**Mid – Hull Deck Plate – Bent Part**Mid – Hull – Bent Part**Bulk Head – Bent Part**Stern – Bent Part**Super Structure – Bent Part**Stern Deck Plate – Bent Part**Activity Involved in the Welding Shop**• Receives steel plates from the Plate shop • Welds the plates along the length of the joints and then assembles the parts • All the parts are joined to build the final assembly**Day – 2: Design Calculations**In the first set of calculations the students are required: • To calculate the weight of the ship • To calculate the draft of the ship • To calculate the kinetic energy of the ship *The formulae and instructions for calculations are given to the students***A**t Q 1. Calculation of Weight of the Water Displaced by the ship Step 1: Area of the Plates Step 2: Volume = Area*thickness where A = Area and t = thickness Step 3: Total Weight = Weight of the ship + Weight of the containers • Weight of the ship = Sum of weight of each steel part • Weight of the containers(1500 TEU containers)(Weight of 1 TEU container=24 tons)**Q 3. Calculation of Kinetic Energy of Ship**KE = ½ * m * v2 We know, 1kg = 9.8 N 1 Ton = 9800 N Weight = m * g Therefore, m = weight/g where g = 9.8m/s2**A1**A1=A3 A4 A4=A6 A2 A2 A5 A5 Area Calculations - Bow Area of Bow= A1+ A2+ A3+ A4+ A5+ A6 = __________sq. mm = ___________sq. m**Calculation of Weight of the Ship**Hull Plate thickness: 5cm and Deck Plate thickness: 2.5cm**Calculation of Weight of Water Displaced by the Ship**Sum of weight of each part = _____________ kg = __________ tons Weight of steel used is approximately 50% of the weight of ship Therefore, the weight of the Ship = ___________ tons Weight of 1 TEU container = 24 tons Weight of 1500 TEU containers = ________________ tons Therefore, weight of water displaced by the ship = Weight of the Ship + Weight of the Containers = ___________________ tons**Q 2. Calculation of Draft of the Ship - Sample**For example: The draft for the corresponding weight of water displaced (shown by the arrow) is 17.5 m**Calculation of K.E of the Ship**KE = ½ * m * v2 Cruising speed = 26 knots (1 knot = .514 m/s) V = ___________ m/s We know, 1kg = 9.8 N, 1 Ton = 9,800 N So, 48,684 tons = _____________ N Weight = m * g (g= 9.8 m/s) m = _______________ kg KE = _________________ J**Assessment**Shipyard Operations Simulation will be assessed based on the following quality characteristics • Cutting on the solid lines • Cutting the corners and intersections properly • Gluing the joints properly • Hull alignment • Bends are straight and creased**Wrap-up**• Make sure all the items are put back in the kit box while returning it to the teacher. • Please clean the working area.
