The Impacts of GNSS Interference on Maritime Safety Report is a special report by the Royal Institute of Navigation (RIN) Maritime GNSS Interference Working Group revealing the impacts of GNSS Interference in the Maritime sector. Survey data was compiled from over 100 sector experts and 300 vessel Captains, supported by interviews with dozens of people involved in the operations and supply chain of vessels that regularly encounter GNSS interference.

GNSS interference refers to anything that disrupts a ship’s satellite-based positioning signals usually caused by: Jamming: blocking or overwhelming the satellite signals with noise so the receiver can’t get a position at all; or spoofing: feeding the receiver false satellite signals so it reports a wrong position that looks legitimate.

Boiler tubes play a critical role in both heat transfer and in maintaining the pressure integrity of marine boilers. When leaks occur, careful evaluation is required to prevent secondary damage.

And DNV has shared guidance on class acceptance criteria, including the assessment of repair feasibility and the follow-up of plug repairs on defective boiler tubes.

Boiler tubes are often exposed to high temperatures, corrosive environments and fluctuating operating conditions, making them susceptible to various forms of degradation. In case of leaks, plugging is often used as a rapid method to restore boiler integrity. Continue reading “DNV guidance on boiler tube plugging class requirements”
