Article GPS (Part 1) - Structure, mode of operation, technical and physical fundamentals of GPS

by Capt. Gunter Schütze, Thailand/Germany - published on 30 January 2020

Of course, as a Nautical Specialist, I also deal with the international discussion on the advantages and disadvantages of satellite-based navigation, e-navigation and conventional terrestrial and astronomical navigation.

Article GPS (Part 2), physical and technical errors of GNSS - an error analysis

by Capt. Gunter Schütze, Thailand/Germany - published on 26 February 2020

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

Article GPS (Part 3) - Accidental interferences and intended Interferences by extern technical sytems

by Capt. Gunter Schütze, Thailand/Germany - published on 6 May 2020

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

Opinion Pilot Ladder - The Weakest Link in Marine Pilotage

by Capt. Santosha K. Nayak - published on 10 August 2020

Pilot transfer arrangement is a sensitive topic to be discussed among the pilot’s fraternity. Although ships are designed and operated with compliance to the SOLAS requirements in all respects including the pilot transfer arrangements, there has been numerous deficiencies observed related to pilot transfer arrangements. The small deficiencies from the part of ships cause life threatening accidents for pilots and sometimes to the ship staff themselves. There are many instances of defective ladder and complacency in proper rigging of ladders has been reported almost every day in different parts of the world. Many pilots lost their life, severely injured for life and face many minor to major accidents. The latest incident being the Capt. Timothy Murray of Sandy hooks Pilot.

Video Dynamic failure of pilot boats: Risk mitigation & management

published on 12 December 2020

Following a surf riding and broaching incident and subsequent collision by an experienced vessel operator, QinetiQ have been undertaking extensive investigations into the risk mitigation and safety management of pilotage operations. This presentation looks to discuss the risks presented during pilotage services, and provide a critical review of vessel design and service delivery approaches to understand the potential risk mitigations and management of pilot boat safety.

Article Risk analysis of collision accidents during underway STS berthing maneuver through integrating fault tree analysis (FTA) into Bayesian network (BN)

by Capt. Mustafa Sökükcü and Cenk Sakar - published on 3 May 2023

This research paper could be useful tool for marine pilots as well during the risk analysis of STS manoeuvrings. In light of the findings of the research, STS manoeuvres may be effectively planned in order to improve overall safety and avoid the unexpected incidents. On the other hand, there is a dearth of literature on STS operation. As a result, this work has a significant input on the current literature.

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).

Video Successful overtaking of another ship in a canal - Port Revel Shiphandling

published on 10 May 2020

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal should be conducted: come in close to the stern and then move away from the bow that will be sucked towards your...
