For 170 years, the San Francisco Bar Pilots have been navigating the world’s largest ships through some of North America’s most difficult waterways. These state and federally-licensed master mariners are highly-specialized ship captains who rely on navigational experience, ship-handling skills, and local knowledge to transport more than $1.2 billion in goods to and from 200 Bay Area ports, docks, and berths every day. This critical service protects more than 1,000 miles of fragile coastline...
This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.
I decided to show the typical happenings when a saltwater freighter arrives Duluth. Most of the time they go to anchor and wait for the Elevator dock. The Pilot Boat brings out the Great Lakes Pilot to sail the ship into the port and to the dock. This vessel arrived early Sunday morning, went to anchor until mid afternoon. They are loading grain at the CHS Elevator in Superor.
Among the few marine professions that purse a man's technical skills and value very high, maritime piloting perhaps is in a class of its own. In this career, the pilot is entrusted to maneuver vessels through some of the most challenging and congested waterways while ensuring seamless integration between shipboard operations and port infrastructure.
