Purpose

This work analyses autonomous ships' specific needs of external and environmental information in restricted pilotage waters. Harbour pilots use conventional well-tested techniques when piloting the manned vessel. In this work, the authors propose technological solutions to be installed or adapted in ports to feed the autonomous ships' systems with the information considered relevant by pilots.

Design/methodology/approach

To investigate what pilots consider relevant, the authors submitted a questionnaire to the pilotage of Paranaguá Port. Then the authors presented a case study including the critical areas for the navigation of ships.

Findings

These technological solutions aim to allow vessels reaching critical areas in a position, a time, a speed and a course that compensates the external forces and/or avoid high-risk situations. The authors have proposed technological solutions considering those already available in the ports, particularly in Paranaguá and Antonina in Brazil.

Originality/value

There is little published data on navigation of ships in pilotage waters. So far, there has been little discussion on autonomous ships in restricted waters.

港口在受限水域的自主船舶技术

目的

这项工作分析了自主船舶在受限引航水域对外部和环境信息的具体需求。港口领航员在驾驶载人船只时使用经过充分测试的传统技术。在这项工作中，作者提出了在港口安装或调整的技术解决方案，以向自主船舶系统提供飞行员认为相关的信息。

设计/方法/方法

为了调查飞行员认为相关的内容，作者向巴拉那瓜港的引航提交了一份调查问卷。然后，作者提出了一个案例研究，包括船舶航行的关键区域。

发现

这些技术解决方案旨在使船舶能够以补偿外力和/或避免高风险情况的位置、时间、速度和路线到达关键区域。考虑到港口已有的技术解决方案，特别是在巴西的巴拉那瓜和安东尼纳，作者提出了技术解决方案。

原创性/价值

很少有关于船舶在引航水域航行的公开数据。到目前为止，关于限制水域自主船舶的讨论很少。
