Every ship transporting goods to, from or through the Arctic wants to find the fastest and safest way through or around the ice. Even service ice breakers save considerable amounts of time and fuel when they choose an easy path through the ice opposed to a straight path.

Pilot recruitment has traditionally been based on seniority, and extensive sea experience. However, a more modern approach, hiring younger, motivated candidates with structured training, offers an alternative path with compelling advantages.

This movie shows how to create the Characteristic Diagram for Wind effect on ships and limits of steerability under strong wind. It uses the previous demos made with the SAMMON Planning Software on turning tendency of ships on straight track and in turning motion.

Matthias Meyer was head of the Bremerhaven port pilots, nautical expert and lecturer at maritime schools. In front of our camera, he voices what has long been a topic of discussion in shipping circles: that the 400-meter container ships have simply become too big for the narrow shipping channels of the Weser and Elbe. In his view, a serious accident is only a matter of time. We take a look at how the district is dealing with these giants and what politicians, BUND and shipowners have to say...

In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...

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...

How do marine pilots work? Example: Bringing a bulkcarrier alongside to „Hansaport“ in Hamburg. Here the tugboats „Prompt“, „Resolute“ and „Bulldog“ are involved. The master has to rely on the pilot. One reason is, that he can‘t know how to deal with these tugs. A maneuver like this is only safe, when the pilot has a lot of practical experience. A master who is doing a maneuver like this only about once or twice a month and each time with tugs he doesn’t know in areas he hasn’t been to...

The Australian company Hart Marine specialises in building pilot and patrol boats of the highest quality.This is not surprising, as the owner's father, Mal Hart, was a harbour master and therefore very familiar with the requirements of a pilot boat.

Video AIS Track by Nolan Dragon - www.MarineTraffic.com What had happened: Container ship APL MEXICO CITY broke off her mooring at Doel, Antwerp, in the afternoon Dec 9, drifted across harbor and contacted DP World pier crane. Crane collapsed and was totally destroyed. No injures reported. Cause of the accident (according to the report from FEBIMA): "The allision of the mv APL MEXICO CITY with a gantry crane at the Port of Antwerp on 9 December 2019 stemmed from exceptional meteorological...
