Factors Influencing the Economic Feasibility of Unmanned Ships

The research effort into unmanned and autonomous ships has increased significantly over the last decade. Although not all required technology is currently commercially available, consensus is that from a technical standpoint, unmanned shipping is possible. The next question is: is it economically feasible to operate an unmanned ship. The...

A task-based analysis of the economic viability of low-manned and unmanned cargo ship concepts

While successful trials for autonomously navigating ships have been conducted, commercially available unmanned cargo ships are currently unavailable. However, there are many solutions available that will allow for low-manned ship concepts long before fully unmanned ships are possible. There are many drivers for low-manned and unmanned...

Cross-Correlated Contrast Source Inversion

In this paper, we improved the performance of the contrast source inversion (CSI) method by incorporating a so-called cross-correlated cost functional, which interrelates the state error and the data error in the measurement domain. The proposed method is referred to as the cross-correlated CSI. It enables better robustness and higher inversion...
