Bow thruster effect on ship's headway 1

When the bow thruster has been in operation for a while, pilots often notice that the ship not only turns but also gains speed. But why is this? Opinion by Capt. Hugues Cauvier.

This video has been recut and edited by the creator Hugues Cauvier. Previously there were three episodes, which have now been combined into one.

Welcome to Point Hope Shipyard in Victoria, British Columbia, Canada. In this video, I follow the float off of the Pacific Navigator, a hardworking pilot boat that serves the Port of Victoria and Ogden Point. We watch as the vessel is pulled along the marine railway, rotated on the turntable, and positioned onto the cradle. Once secured, the cradle lowers to float-off depth, and the Pacific Navigator fires up her engines for a short harbour spin before returning to duty. Some segments,...

Blog: https://www.merrimacins.com/understanding-and-preventing-tug-barge-risks/ Understanding and Preventing Tug & Barge Risks The maritime industry relies on tugboats and barges for a wide range of applications. Tugs are used to pilot vessels into and out of ports, while barges are used to transport bulk materials. The relationship between tugs and barges is critical, as most barges are not self-propelled and must rely on the skilled operation of a tug or tugs for propulsion. At Merrimac...

The Arctic magnetic pole does not move anymore. It runs, faster and faster. In recent years, even faster than expected. Therefore, geo-researchers have now had an unscheduled change to their world model and adjust their calculations, so that navigation with compass and other navigation aids such as a Pilot Plug, used by pilots around the world, continue to work.

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

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...

Ever Forward Freed What's Going on With Shipping? April 17, 2022 In this episode, Sal Mercogliano - former merchant mariner and maritime historian at Campbell University - discusses the successful ungrounding of MV Ever Forward from its location outside of Baltimore and its movement to an anchorage off Annapolis. This video will be followed by another with detailed photos and videos once they can be compiled. #EverForward #Cheasapeake #Evergreen #container #containership #logistics...
