Article World's first methanol-powered pilot boat launched
published on 14 December 2021
The Swedish Maritime Administration is launching the world's first fully methanol-powered pilot boat today, It is one of the ministry's existing pilot boats, which has now been converted to test the new propellant. The work is part of the Swedish Maritime Administration's transition to a fossil-free fleet.

Video Tug Girding
published on 30 November 2020
Between 2005 and 2018, the TSB received reports of 26 girding situations resulting in 21 capsizings. Girding occurs when a vessel is pulled broadside by a towline force and is unable to manoeuver out of this position. The TSB created this video to illustrate the factors leading to girding and the recovery methods.
The TSB would like to thank Ledcor Resources and Transportation Inc. for use of simulator training images in the girding video. We would also like to acknowledge the U.S....
Video Spiral-Test -Manoeuvre for detailed identification of Yaw Stability using Samples of Cruise Ship
published on 29 September 2021
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.
Article Watch out for hydrodynamic effects when manoeuvring your ship in restricted waterways
by SWZ|Maritime - published on 14 October 2021
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.
