远程，无人驾驶，随时待命

世界上的海洋确实是一片广阔的空间. When an ocean-going vessel like a deep-sea fishing trawler or a research craft runs into trouble hundreds of kilometres from shore, it can take many hours – even days – for meaningful help to arrive on the scene.

But what if an uncrewed rescue craft could be more or less permanently stationed on remote areas of the ocean, 随时准备应对紧急情况? Could it help save lives at sea and enable maritime nations to better meet their search and rescue obligations?

码头漫游可选载人高速救援船
 

This line of thinking recently inspired staff at Saab’s Docksta Shipyard to develop a concept for a new generation of rescue craft capable of being operated remotely and remaining at sea for weeks at a time. 被称为码头游荡者, 可以载人, 高速救援船(LHSRV), the proposed vessel could potentially travel at speeds in excess of 40 knots to maritime emergencies to provide a safe evacuation point for up to 20 survivors at a time.

The concept was recently unveiled to the shipping and rescue communities by Saab’s Emil Jonze at the World Maritime Rescue Congress and the Royal Institution of 海军 Architects 11th instalment of the Surveillance, 搜救船(SURV)会议在鹿特丹举行. Audiences heard that one potential application for the craft is in the oceans around 加拿大, where accidents frequently occur in cold waters more than 100 nautical miles from shore. The LHRSV has been developed in cooperation with John Dalziel and Ron Pelot from Dalhousie University, 哈利法克斯, 加拿大.

加强救援反应
 

The starting point for the development of the LHSRV’s concept was understanding the limitations of current rescue resources for remote ocean emergencies. 根据国际海上人命安全公约, national governments are required to operate and maintain search and rescue facilities within their designated rescue zones. 有船员的船只可以用于这样的救援, 但是在空间站上维护它们是很昂贵的, 相对缓慢，受恶劣天气影响. Fixed wing aircraft have limited time on station and rescue capabilities, 而直升机的航程有严格的限制, 现场时间和幸存者能力.

Robust design with features to enhance long range and withstand cold water

The proposed features of the LHSRV would allow it to overcome many of these challenges, and to work in cooperation with conventional search and rescue platforms. 长20米, the concept vessel’s hull would be based on Saab’s successful Docksta 20 Interceptor craft, 目前用于巡逻. 铝制结构, the LHSRV would feature a self-righting design to allow it to quickly recover from capsizes and to survive rough seas. A superstructure designed to minimise ice build-up would allow for operation in cold water environments, 比如北大西洋. 与此同时, a substantial battery system capable of being recharged by both a generator and photovoltaic cells would enable the craft to remain on station in the remote ocean for periods of between five and 20 weeks, 视情况而定. The range for rescue missions would be up to 300 nautical miles on top of loitering time, with the vessel able to travel 200 nautical miles or more to reach its station.

完全远程操作

The LHSRV would make use of cutting-edge autonomous and remote-operation technologies, 其中一些已经展示了十大正规博彩网站排名的执行者III测试艇. These would allow it to be controlled entirely remotely from a control room on land. 船上没有船员, the craft could achieve speeds in high seas that no equivalent crewed vessel could manage.

一次在事故或事件的现场, LHSRV可能有很多潜在的功能. Remote communications features would allow it to act as a communication hub and to interact with the crew of stricken vessels. A remotely operated man-overboard system would allow it to retrieve survivors al读y in the water and receive evacuees from sinking vessels. The LHSRV could then potentially convey survivors to shore or stay on the scene until other resources arrive.

The interior of the vessel includes an emergency helmsman seat to allow one person to manoeuvre and pilot the vessel. A range of life-support compartments would provide space for those who have been rescued. These spaces feature soft, rounded edges to avoid evacuees being injured in high seas.

While the initial application proposed by the Docksta team is within Canadian waters, many other nations are regularly called on to perform rescues in remote parts of the ocean. 这个概念可以在新西兰周围的水域使用, 澳大利亚, 丹麦, 冰岛, 以及挪威的斯瓦尔巴群岛.

The next step in the development of the LHSRV would be the construction of a prototype.
