APPENDIX C QUESTIONNAIRE TO PILOTS' ORGANI ZATIONS * 1. Name of pilot organization 2. What waterways and ports are served by your organization? 3. What are the various channel sizes (depth/width) encountered along this route? What are the types and sizes of vessels transiting these channels? 5. What major commodities are carried by these vessels? 6. Are the channels adequate for the maneuvering requirements of the vessels you pilot through them? 7. What vessels present the greatest problems in maneuvering and control? 8. What areas pose navigational difficulties in the entrances, channels, and harbor turning basins of your pilotage route? 9. In the areas described above, what major factors contribute to controllability and maneuvering problems (e.g., channel constriction, shoaling or underkeel clearance, high winds, strong currents)? 4. What practices have pilots agreed to among themselves to compensate for the deficiencies in channel design (one-way traffic, restricted passing/overtaking in bends and turns, etc.) 11. Would deepening or widening entrance channels, river or approach channels, and turning basins improve ship maneuverability and control? *Distributed, collected, and analyzed by the Technical Panel on Ports, Harbors, and Navigational Channels, Study of National Dredging Issues. 149 ~ ?
150 12. What specific areas should be deepened and/or widened to improve vessel maneuverability and control in your pilotage area? 13. Do your pilots consider the navigation aids in your area adequate or in need of improvement? 14. Would improved navigational aids substitute for improvements in channel depth, width, or design? What other methods are used in your pilotage area to compensate for inadequate channels (e.g., use of tugboats, high-water transit, transit with or against current)? 16. What is the maximum draft of vessels calling at your ports? 17. What underkeel clearance is recommended for transiting your channels? 18. What is the type of bottom in areas of critical underkeel clearance (sand, rock, variable)? 19. How was the recommended underkeel clearance established? 20. What traffic control systems (other than those operated by government agencies) have been established to compensate for deficiencies in the navigational channels of your area? - 21. How often is maintenance dredging performed in your channels? 22. Do your pilots consider the maintenance dredging schedule adequate for the channels along your pilotage route? 23. Generally, what is your assessment of the adequacy of your waterways for the traffic and conditions experienced by your pilots and what solutions would you recommend for improvement?
