The average lifespan of a ship is 25-30 years. After this span, the ship may become too expensive to operate, but most importantly, to become unseaworthy putting human safety at risk. So, have you ever wondered what happens to a ship when it is too old to sail?

After the 9/11 attacks that changed the world, IMO requires every ship above 500 GT sailing the world’s oceans to have a Ship Security Alert System (SSAS) to enhance security. Have you ever wondered what this system is and how it works?
