How Stabilisers Reduce A Ship's Roll

This video explains the impact of lateral resistance on the turning circle of a vessel using animations. The video explains the term lateral resistance, shows an example of its impact on the turning circle and its associated aspects (advance, transfer, tactical diameter and drift angle).
Contents of this video will benefit mariners preparing for exams (written and oral examinations).

The COVID-19 pandemic has brought unprecedented challenges to the maritime supply chain and called for accelerated adoption of digital technologies in various aspects of maritime operations, including the area of maritime education and training (MET).

The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

Hardest part of getting on board of a ship is climbing up on a maximum height of pilot ladder as 9m. Vessel on that video is a 27kdwt bulk carrier in ballast condition bound for İstanbul strait northbound passage.

Over the past two years, RightShip has reviewed more than 21,000 PSC inspections, assessed over 2,500 incidents, and inspected over 4,600 vessels. This is in addition to the reviewing a large number of SIRE reports as part of the vetting process. Despite the industry’s efforts and campaigns to educate, we have observed an upward trend in deficiencies and non-conformities involving pilot ladders and arrangements. The data gathered from RightShip Inspections indicates that the pilot ladder...

According to many training experts, including Malcom Gladwell, from his book Outliers: Story of Success, 10.000 hours is the point in which a standard professional acquires the qualities necessary to perform any work with master skill.

Surely, the new invention also reduced the amount of time and hands (manpower) previously required to perform such a task. Now those idling "extra hands" could dedicate the "extra time" that was made available, to take care of other issues important for the community.

Does the growth of ships ever have limits? Perhaps less in shipbuilding than in the handling of the ships during piloting.
