How AIS Works - Operation of AIS

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

OHB subsidiary LuxSpace’s satellite for global ship monitoring has reached its target orbit.

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.

Blog: https://www.merrimacins.com/understanding-and-preventing-tug-barge-risks/ Understanding and Preventing Tug & Barge Risks The maritime industry relies on tugboats and barges for a wide range of applications. Tugs are used to pilot vessels into and out of ports, while barges are used to transport bulk materials. The relationship between tugs and barges is critical, as most barges are not self-propelled and must rely on the skilled operation of a tug or tugs for propulsion. At Merrimac...

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.

Going down the accommodation ladder with neither lifevest nor safety line must have been based on similar, past, successful operations, which may have never been challenged on board. This ‘slippage’ in safety is a pernicious and common phenomenon.

Delta Launch Services, the operating company for the Associated Branch pilots on the SW Pass of the Mississippi, has taken delivery of a new pilot boat from Gladding-Hearn Shipbuilding, Duclos Corporation. This is the sixth St. John’s Class launch built for the Delta pilots by the Somerset, Mass. shipyard.
