Video Safe at sea with satellites (AIS)

Found on YouTube. Created by "European Space Agency, ESA"

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills. The European Space Agency is once again at the forefront developing new technologies and satellites: to keep us safe at sea and to monitor the environment. Space makes a difference here on Earth and certainly at sea where there is no infrastructure.

Opinion Pilot Ladder - The Weakest Link in Marine Pilotage

by Capt. Santosha K Naya - published

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 How Ship Anchor Works? - Procedure For Anchoring a Ship at Sea

#Anchor #shipanchor #windlass
Anchoring is one of the very frequent operations onboard ships. A number of variables and external factors influence the duration and location of an anchoring operation. While the type of seabed is of utmost importance during anchoring, soft muddy grounds or clay bottoms are best preferred. It should be taken care that the anchoring bottom is free of power lines, submarine cables, pipelines or rocks.

Various methods on anchoring include consideration of direction and strength of wind, current and tidal stream. Often good local knowledge helps a mariner determine required manoeuvres and actions to be taken while anchoring.

This operations comes under the responsibility of deck officers. It involves the use of critical shipboard equipment and requires high level of situational awareness. The key responsibility of the deck officer at an anchor station is to use the anchoring machinery and available man power for carrying out the operation safely and efficiently in accordance with the master’s instructions.

In most of the cases, theoretical guidelines and bookish knowledge are helpful only to an extent. Situational awareness and spontaneity of the officers, and their instant decision making capability helps to carry out the operation fruitfully. A good knowledge of ship’s maneuverability and the limitation of the equipment involved will further help the officer to make such spontaneous decisions. The competency of the officer is decided upon his ability to consider the situation, command his crew and to assess the orders give by the Master, to carry out the operation safely and efficiently.

Opinion Scientific Fact: The ‘traditional’ understanding of the ship’s pivot point is wrong!

by Tim Cummins, Harbour Pilot, Portsmouth International Port - published

In fact, the pivot point that we “see” is a trick of the eye, it looks like the ship is rotating about this point but in fact it is elsewhere, a point that you cannot see.
