As a consequence of recent IMO regulations, shipowners are requested to improve energy efficiency of their ships’ operation with regard to various factors that drive fuel consumption and emissions. The German navigation system manufacturer Raytheon Anschütz addresses these requirements with their newly developed autopilot series NP 5000. As one of the first customers, the US-based Overseas Shipholding Group (OSG) has contracted Raytheon Anschütz for retrofitting existing autopilot systems on their fleet of oil tankers with the newly developed Anschütz NautoPilot 5300.
