by Capt.Alpertunga Anıker - published on 24 November 2022
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.
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.

GNSS interference has become a growing challenge in the Baltic Sea, affecting maritime navigation, aviation, and critical infrastructure. While numerous datasets and services, such as gpsjam.org, spoofing.skai-data-services.com, and flightradar24, report high-altitude GNSS interference based on ADS-B data, there is a significant lack of studies focusing on ground-level interference.
Article New app: Pilot´s Tug Assist Tool PTAT - Bollard Pull Calculation for Marine Pilots
by Capt. M. Baykal Yaylai - published on 19 February 2020
Required tug power and number of tugs needed in variable conditions of wind, current and waves isin most cases an assessment made by pilots based on their professional experience. However, assessments will raise questions by lawyers if something goes wrong. They will use tools to calculate what really is needed with respect to tug power and number of tugs. They have furthermore the advantage of time.
