This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...
Using pictures and sketches, this video finally explains the difference between gross tonnage (GRT) and net tonnage (NRT); the ship spaces that are included/excluded in their calculation; and the importance of these terms to ship owners.
Contents of this video will benefit mariners preparing for exams (written and oral examinations).
The pilot plays a crucial role in the safe navigation of the vessel to her destination. Expert in the local waters, a Pilot is imperative to the Bridge Team. Berthing/un-berthing, anchoring, transiting narrow channels etc. are very specialized operations and require expertise of a very objective manner that results in efficient planning, monitoring and execution of safe passage. When a ship needs to enter or leave a harbor, marine pilots are sent aboard via a small pilot boat to safely...
he safety of pilot boarding and disembarkation is a major headache for the shipping industry. Every year, many pilots are injured or died due to old (worn-out) or improperly rigged pilot ladder facilities, and/or the process of placing the pilot ladder results in injuries to the crew, notes Capt.Zhao Qingwei, Marine Safety Manager at DASIN SHIPPING PTE LTD.
