2 Hvad er udfordringerne? - Kampen om vand og land - Kan man bringe større skibe ind i eksisterende havne og derved øge godsmængden? - Vil et krav om at flytte gods fra land til skib betyde, at havnene skal håndtere nye/større skibstyper? - Skal vi have LNG terminaler i DK, og hvor skal de ligge? - Hvordan kan simulator studier bidrage til at kaste lys over disse områder?

3 Division for Maritime Industry (DMI) Facilities 9 Simulators: 3 Full Mission Simulators 1 Part Task Facility 1 Full Mission Tug Simulator 3 Tug Simulator Cubicles 1 DP simulator (Certified by NI) 2 Towing Tanks: 1 deep / 1 shallow 4 Wind Tunnels: high speed, boundary layer, wide, climatic

4 Benefits of Navigational Port Studies Increased safety Enhanced efficiency Financial savings (e.g. dredging, channel width, nav. marks) Larger ships into a specific port Bringing navigators, engineers, and authorities together, resulting in consensus

5 Optimised Port Layout through FORCE Technology investigations of: Channel and basin layout Breakwater layout and structures Navigational safety Berthing and mooring safety Down time predictions Dredging Environmental impacts Coastline changes

6 Phases in port development Feasibility Stage Design Stage Construction Stage Upgrading of Existing Port (FS) (DS) (CS) (UEP)

7 (Grid spacing 20 meter) Feasibility Stage Field investigations (measurements, surveying) Establishment of environmental baseline conditions ( tide, wave, current, and sediment transport) Assessment of preliminary port and channel layout 560 N m/s Speed, m/s Above Below (Grid spacing 20 meter) 03/01/01 18:40:00 F S DS CS UEP

8 Design Stage (I) Approach channel evaluation (one way - two way traffic, width, depth, turns) Harbour entrance evaluation (orientation and width) Turning basin evaluation (size, position) Navigational aids planning Dredging limits Tug requirements F S DS CS UEP

9 Design Stage (II) Berths evaluation/ downtime minimisation Risk of grounding (wave and manoeuvre induced motions, squat) Bridge crossing waterways (collision, grounding) Breakwater design F S DS CS UEP

10 Construction Stage Approach/departure conditions (safe and efficient passage of construction field) Tug capacity/strategy Ship motions under operation Environmental limit for operations Down time for operations Environmental impact minimisation F S DS CS UEP

11 Upgrade of Existing Port Larger vessels into existing ports: Approach/departure conditions Berthing manoeuvres Tug capacity/strategy Ship motions of moored vessels Controllability of vessels at limited water depth Risk of grounding, wave and manoeuvre induced motions, squat Environmental limits Risk assessment F S DS CS UEP

12 Previous Experiences Køge Havn Evaluation of enlargement of existing port Outcome: Safe operation during construction phase and for final lay-out Identification of operational limits for future larger vessels arriving to the new port Determination of placement and size of turning circles and AtoN Bring Navigators, Naval Architects and Port Designers into same room to obtain consensus

13 Previous Experiences new cruise terminal Copenhagen Evaluation of berthing of large cruise vessels and passing traffic Outcome: Testing of design and feasibility of berth Determination of weather limits Determination of width and placement of channel Determination of passing ship s speed and distance Determination of turning circle size and position and AtoN placement Bring Navigators and Port Designers into same room to obtain consensus

14 Previous Experiences Venice Lagoon, Italy Maneuvering simulations in present, intermediate and final layout of inlets into the Venice Lagoon Outcome: Approval of project/design by local pilots Safety issues identified in intermediate layout Evaluation of final layout

15 Previous Experiences Port of Pipavav, India Fast time simulation, grounding study of navigational channel Outcome: Recommendation on minimum required depth of navigational channel Guidelines minimising the risk of grounding for approach and departure Estimation of down time for navigational channel/port Inbound Outbound

16 Full Mission Tug Simulation

18 New 360 deg tug simulator

19 Example (I) Exxon Mobil / Aker Kvaerner Purpose Determination of optimal tug configuration in terms of size and type for offshore LNG terminal operations. Determination of optimal tug and ship handling strategies. Facilities A-bridge. Fully modelled ASD/VSP tug 2 x cubicles. 2 x Fully modelled ASD/VSP tugs D-bridge. Fully modelled LNG carriers Outcome Determination of optimal tug size and type and tug handling strategies for normal and emergency scenarios.

20 Example (II) Tow-out operation Blue curve is tugs grounding curve

21 New IALA Guideline on use of simulators IALA Guideline 1058 on use of simulators for design of waterways and planning of aids to navigation - Description of simulator tools - Fast time - Desk top - Part time - Full Mission - Full Mission Tug System - Traffic flow - The limitations of various simulation tools - Requirements for participants, simlator staff and documentation - Download from under Guidelines - PIANC Guideline often too conservative simulation can prove safety OK with less width
