“…The effects of remote pilotage on safety have not yet been studied intensively. However, based on a few published studies, remote pilotage is expected to have benefits in addition to the improvement of the pilots' work safety [4], [5]. These include, among others, improved navigation safety, improved pilot utilization rate and reduced costs of pilotage support services [4].…”

Starting from a short study on pilotage transfers in terms of safety and sustainability as a motivation, this paper will draft trust requirements from pilots and navigators to remote based systems, before the capabilities of Extended Reality (XR) for these requirements are highlighted. This is followed by outlining the technical approach used within Sea4Value Fairway (S4VF) project and Remote Pilotage – Operational, innovative and Manageable Alternatives for Navigation routines (RePO MAN). The technical implementation within the context of the the use case method is explained and a consolidation of these use cases within the framework of RePO MAN and the possibility of adaptation in further field tests up to implementation is considered. Finally, limitations and deficits of remote pilot concepts will be outlined using the example of RePO MAN merged with the results of the S4VF project.

“…Maritime stakeholders are exploring the viability of operational transformation using increased automation and digitalisation. One of them is the Remote pilotage operation (RPO), which is currently at the development stage in Europe in several countries (Hadley and Pourzanjani, 2003;Lahtinen et al, 2020;Salonen et al, 2020). In addition to identification and risk analysis techniques.…”

“…Furthermore, it is demonstrated how the remote pilotage risk model can support pilots and pilotage companies in real-time decision-making by estimating the likelihood of losses in case of a single fault or failure. the potential cost reduction (Danish Maritime Authority, 2014), RPO may improve maritime safety by reducing human errors and risks related to pilot embarkation and disembarkation (Lahtinen et al, 2020). However, the increased automation and digitalisation can propagate unrecognised risks due to software flaws, design flaws, and ineffective communication and condition monitoring during pilotage (…”

“…Tugboats serve a range of berthing, salvage and ice-breaking shipping operations (see Figure 1) [1]. Yet, accidents that involve tugboat operations in confined waters and fairways are broadly associated with wrong decision making [2,3]. A review of accidents reported in the Baltic Sea area during the past two decades [4,5] reveals that poor communication during tug operations and the lack of pilotage assistance are the major causes of accidents between 1997 and 2011 [6].…”

This paper introduces a RANS CFD methodology for the evaluation of tugboat dynamics during pushing operations. Two- and three- dimensional methods that respectively utilize “Dynamic Fluid Body Interactions - (DFBI)” and “Tug Force Equilibrium kinematics-(TFE)” are assessed and compared with the aim to better understand the influence of fluid modelling on ship dynamics. For the DFBI method, an unsteady RANS solver comprising of a dynamic fluid body interaction module and a contact mechanics coupling algorithm are used to predict the forces between a tugboat and an assisted ship. For the TFE method, a steady RANS method is applied and contact actions are calculated as a sum of the hydrodynamic forces on the hull and the propeller. Whereas DFBI accounts for the time variation of the contact forces, the TFE is more rapid and could be used to derive operational decision support criteria. To demonstrate the latter the TFE method is used to derive the pushing forces based on a set of 16 numerical simulations. It is concluded that irrespective of the model used the tugboat speed and orientation may amplify the pushing forces. This effect could be prominent, especially at slow speeds for which the sway force acts in opposite direction to the tug.
