    Providing the best possible support to commissioning engineers is critical for efficient execution of commissioning and on-time delivery of a shipbuilding project. This paper contributes to current research on the digitization of maritime commissioning and builds on existing approaches to a digital twin. Based on an analysis of the execution process, this paper presents a human-centric digital assistance system that is designed to provide the commissioning engineers with an improved information supply and to increase situational awareness in the complex and error-prone ETO process. In addition, the system can be connected to the ship automation system via OPC UA to display, check, and document sensor values directly in the assistance system. Problems and rework items can be documented context-sensitively and with little effort and fed back into the digital twin. The automated documentation and continuous enrichment of the digital twin help reduce effort, make the commissioning process more transparent, and progress indications more resilient. The prototype implementation at three shipyards promises improvements in productivity and quality.

    Efficient commissioning is essential in maritime one-off production to be able to hand over a ship to the customer in the desired quality and at the agreed time. The large number of scheduling and technical constraints and the high process uncertainties are a major challenge for the planning and control of commissioning. This paper works out the specific requirements of maritime commissioning and derives a suitable planning and control logic. This logic is implemented into a digital assistant and is divided into a planning module and a control module. The planning module is the focus of this paper and determines a suitable plan sequence of commissioning tasks and sets their plan dates. The control module will use this plan data and will provide support during commissioning based on the current progress in releasing, sequencing and assigning the commissioning tasks. The goal is to improve the quality and productivity of the planning and control of commissioning at the shipyards and thereby to support the overall coordination of the commissioning process. The developed assistant is part of a modular assistance system that also consists of an authoring and an execution assistant.
