Leap Second Addition - What it means to you

Leap Second Addition - What it means to you blog article image

 

A leap second is simply, an additional second that is added to Coordinated Universal Time (UTC) every so often to ensure that the atomic clock is synchronized with the Earth's rotation. Since introduced in 1972, there have been 25 leap seconds added and the next one is due to be added at midnight on 30th June 2015.

The prediction is that these will become more frequent in the future as periodic variations caused by atmospheric winds and the tidal interaction of the Earth and the Moon causes a secular slowing down of the Earth’s rotation.

How could this affect you and your MOB solution?

The non-adjustment of an AIS transmitter could mean the signal from your AIS PLB / MSLD is not picked up, resulting in a man overboard being lost and significantly increasing the chance of a fatality.

If the signal is picked up, there is then still a chance that the location of the man overboard can be wrong by up to 500m, a significant distance when searching the ocean for an MOB.

With the added significance of the leap second adjustment, Annual Service & Recertification is imperative in order to ensure all life saving equipment is fit for use and maintained to the highest operational standards.

From 31st June 2015 all sMRT AIS alerting units that come back for Annual Service & Recertification will have the leap second adjustment added in order to avoid the risk of location errors and the signal not being picked up.

MRT is a responsible manufacturer and provider to some of the worlds biggest offshore companies and do not take any risks when it comes to the safety of the men and women that work in the most hazardous marine conditions.
