Transport capacity and service speed of ships have increased exponentially over the last decades. The consequence of this trend is increased loading on the cargo. Under pressure of market economy, the state of the art in technical know-how has been overtaken by day to day practice. Containers, cars, trucks and other cargo are being transported in heavy seas and high winds without the knowledge of the actual lashing loads. Every year tens of thousands of containers, cars and trucks are lost or damaged at sea. Besides the economical damage, lost containers often remain afloat for weeks, making it dangerous objects to collide on. Addressing the problem is a difficult matter since safety aspects and economic efficiency as well as the different parties involved have conflicting interests.
