Video Operation of POD Ships - Discussion on Efficiency comparing Conventional and IN-OUT POD strategy
published on 8 June 2022
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...
Article Origins of the IMPA pilot mark
by Kevin Vallance deep sea pilot and author - published on 24 October 2019
There are many things in both our everyday and professional lives which we take for granted and never question the origins of, an example of this might be the IMPA recommended ‘pilot mark or pilot line’, which is sometimes seen on the side of vessels indicating where a vessels freeboard exceeds 9 metres.
Video What is the impact of lateral resistance on a ship's turning circle??
published on 3 September 2020
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).
Article A review of the ship’s pivot point: Science, Maths and Observation’ Where is the centre of a ship’s rotation?
by Tim Cummins, Harbour Pilot, Portsmouth International Port - published on 17 July 2020
This my attempt to do just that. This is a summary of all scientific papers and articles that I could find about the ship’s pivot point. I have added links to any videos associated with the publications and have also included any useful diagrams or equations that the authors published to help explain their research.
Article British Ports Association Eyeing up Autonomous shipping possibilities
published on 26 August 2020
The British Ports Association has launched a new initiative looking at the implications of autonomous shipping for UK ports, including a call for evidence from interested parties. Maritime Autonomous Surface Ships (MASS) involves the automation of vessel and onboard processes which could alter how ports and ships interface with each other. The BPA which represents the majority of UK port activity including 85% of the shipping movements in and out of the country, is keen to explore what the future developments of shipping will mean for the sector.
Video Safety with HamiltonJet (Waterjet)
published on 1 July 2020
Waterjets are the safest choice for Pilot Boat applications. Our waterjets are engineered with safety in mind, precise steering control and efficient manoeuvrability result in effective and quick reaction to a man-overboard situation, and with no exposed propeller, waterjets provide ultimate safety around people in the water.
