Ns345 W6D2 Ship Interactions and Bank Effects

Drydocking or undocking is always a difficult task, particularly with a “dead” vessel (no power/propulsion) and the wind blowing on the ship's side.

Currently, several means of transport are undergoing an accelerated development towards automation and automated movements. This development will also impact future ship handling with tugs. A glimpse into the future of tug boat operation.

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.

To monitor the vessel’s progress, the pilot had set up his portable pilotage unit (PPU). He had connected the rate-of-turn generator to the vessel’s pilot plug and had set a variable range marker on the radar with a radius of 0.5 nm.

On the occasion of the Maritime Safety Week (July 4-10), UK MAIB’s inspector Bill Evans refers to the issue of unsafe pilot ladders, a concern that has been regularly voiced by the industry.

At the A&R shipyard in Germany, the successful principle of SWATH boats was further developed in 2013: The SWASH principle allows sea-going, smaller and more economical boats.

The pilot leaps to his boat accompanied by claps and exclamations of; "Bravo!".
