Thousands of miles across the open ocean can seem like the easy part of a ship's journey. The real challenge begins when a massive vessel reaches the final few dozen miles, where open water gives way to narrow channels, strict traffic controls, powerful tugboats, and enormous locks. Nowhere is this more apparent than at the Panama Canal, where ships must be carefully guided through a complex system designed to move them between two oceans. So how can the last few miles of a journey become...
Research on hydrodynamic interaction indicates that if the speed of the ship near a bank is too high, the rudder may be less able to cope with the forces induced and control will be lost. The Nautical Institute highlights this in its latest Mars Report, in which an LPG carrier hit a barge being towed by a tugboat as a result of hydrodynamic forces.
May is Maritime Month at the Port of San Diego and we are proud to highlight some of our hardworking men and women of the Working Waterfront. Meet Captain Lyle Donovan, a San Diego Bay pilot with the San Diego Bay Pilots Association. His work consists of guiding ships in and out of San Diego Bay in a safe and efficient manner. A typical day includes guiding a 650-foot car carrying vessel or a 950-foot cruise ship into San Diego Bay. This entails boarding the vessels by climbing up a ladder,...
