With the fast development of telecommunication technology, the Internet service upon ships has also raised significant notice in the maritime industry. Similar to the fundamental functions of communication on land, the support of Internet service is also crucial to navigation at sea. The Internet services on ships benefits not only ship management, but also the crew on the ship. This article will delve the reasons for this propensity of wide Internet service application in maritime industry.
For ship management
One safe and successful ship navigation usually requires multiple teams to build efficient cooperation together. One of the most important reason for Internet access on ship would be real-time transmission of navigating information, such as precise routing and weather information. In today’s marine industry, especially for commercial ships, not only the seafarers need to locate themselves at sea, but the ground supporting team also need to determine where they are with astonishing detail. And broadband Internet access makes this possible today.
According to Mærsk Mc-Kinney Møller Center, there are over 100,000 commercial vessels over the world consuming around 300 million tons of fuel every year. Nowadays, zero-carbon shipping has become a propensity in the maritime industry. As reported by Mckinsey, the full decarbonization of the maritime industry is expected to achieve by 2050. In order to achieve this ambitious goal, shipping companies are urged to set up systems for daily monitoring, reporting and verification (MRV) of emissions for individual ships, which requires consistent Internet connectivity at sea. With the support of Internet service, the real-time fuel consumption and emission information can be transmitted to the ground team and they could respond instantly.
Last but not least, consistent Internet connectivity could also help to bolster security against pirates and other threats. With the support of surveillance cameras together with Internet access, law enforcement or naval agencies can keep updates with any robust information about a potential pirate threat: size, sophistication, and weaponry. The surveillance systems are able to transmit footage to related team on shore to respond with suggestions through Internet communications.
For the crew on the ship
In addition to efficient ship management, offering Internet service for the crew on ship is also important. First, the Internet helps with crew medicine issues. There are usually only seamen on ship during its navigation and seldom with physicians. The Internet connectivity enables physicians on the ground to do some telemedicine help and provide some remote medical suggestions for seamen on board. In addition, as the navigation trip usually takes a long time of weeks or even months, online entertainment is crucial to a growing number of seamen. With the support of broadband Internet service, they are able to keep abreast with current affairs and sporting events, manage finances, keep in touch with family and friends on social media platforms and many others. This helps to enrich their sea life a lot.
DITEL maritime antennas
In order to provide consistent Internet connectivity for vessels at sea, DITEL has develops various models for different applications. One of our most popular VSAT model is V81. This model has been installed in many different countries and provide satisfying performance. With its 3-axis stabilized platform and auto tracking system, our V81 is able to offer exceptional value and superior RF performance, ensuring easy operation on board as well as access to remote support whenever it needs. This model especially suits for large vessels, such as commercial vessel and wind installation vessel. It supports remote control by PC and mobile, video monitoring, broadband, video conference, VoIP and other network applications.
