This issue includes articles related to the problems of transportation safety (chemical cargo carriers, LNG transportation), the latest research in the field of design and operation of marine machinery (including condition assessment of mud pumps for drillships, design of submersible autonomous vehicles and advances in maritime measuring techniques), as well as state-of-the-art solutions for maritime communication, navigation data processing and maritime positioning systems for vessels (Automatic Identification Systems, radar systems, and the Global Navigation Satellite System). We have also included a particularly interesting article entitled “On navigation as a scientific discipline” which summarizes the existing achievements in the field of navigation and describes the potential to classify navigation as an independent scientific discipline.
