A digital twin is a asset that simulates the behaviours of physical counterpart. Digital ship literature identifies concept already being applied to specialised problems, but no clear guide exists for creating broader interdisciplinary twins. Relevant dimensions product data modelling and previous attempts at standardizing elucidate requirements effective in context. Such are placed perspective implementation encompasses challenges directions future development services, networks, software....

The case study applies standards-based experiment involved a scale model ship equipped with dynamic positioning system under artificial waves. prototype illustrated capability mirroring controlling model's position in real-time, predicting motion responses across...

A core aspect of temporal complexity in the design non-transport vessels is uncertainty related to future market and contract opportunities, corresponding changeability that should be incorporated into ship meet this uncertainty. The development an appropriate specification for a new represents strategic decision owners as part fleet renewal or expansion programme, with high financial risk long time horizon typically 20-30 years. This type one out several aspects handled process. In paper we...

The digital twin concept describes a comprehensive model used to monitor and simulate an existing asset in nearly real-time. In maritime context, twins do not yet have wide selection of standards support interoperability among systems, undermining users’ ability create cohesive that combines multiple software suites. This study proposes open framework for organizing ship sensor data twins. is based on principles product management, allowing use taxonomies suitable across stages the lifecycle...

This paper describes how application of Machine Learning (ML) in Product Lifecycle Management (PLM) system results reducing time engineering change order (ECO), i.e., implementation the design change’s effects, and thus, improving responsiveness manufacturing system. A current challenge PLM is long duration process from when a component product’s changed until reflected operation which consumed. proposes that supervised ML, using classification method basic neural network algorithm, on 3D...

Hydrodynamic simulation of marine structures is a complex and time-consuming task that requires large, refined models to accurately estimate the behavior ships. During conceptual phase, therefore, these estimations may be more efficient if done with mix surrogate simplified simulations. We believe AI web environment can contribute providing precise answer fast solution, especially when design domain narrowed properly estimated. This paper shows an attempt in this direction, describing...

This article approaches the complexity aspects of conceptual ship design from a systems engineering point view. We introduce issue by defining term in engineering, placing task as complex system problem and creating analogies between generic ship. Five main are presented, linking challenges phase to each aspects. The structural aspect is related arrangement interrelationship physical objects behavioral derives form-function mapping. external circumstances which subjected approached through...

A core aspect of assessing the environmental footprint ships during conceptual design phase is estimation total air emission vessel life cycle. This process must take into account not only an appropriate propulsion system and controls but also uncertainty related to changes in mission, such as future market conditions, new regulations, contract opportunities.

This paper discusses how Product Life-cycle Management (PLM) tools can benefit the ship design process. Primarily, concept of PLM applied to will be decomposed in six key elements: database, modeling and simulation tools, value chain processes, product hierarchy management, management project management. Some these elements rely heavily on use Virtual Prototyping achieved. The next step applies concepts chain. done through development a simplified scenario, where it is discussed vessel...

This paper proposes a modular approach as technique to enhance Virtual Prototype (VP) in conceptual ship design. The methodology preliminary division, which is made according the systems functionality. modules obtained from division are analyzed relation how they interact among themselves (compatibility) well relevant for efficient performance of mission (performance). An entity model virtually assembled and evaluated, feeding an application that able simulate all possible module’s...

The concept of unmanned ships capable being controlled remotely is now beyond the idea and will start a revolution in maritime industry. In this context, remote ship operations refer to processes controlling vessels from distance such that operators obtain information sensors. Thus, assessment improvement human interactions can enhance overall performance operations. However, there are unknown (i) human-human (ii) human-machine relationships operations, which increase complexity therefore...

Parametric structural design is a promising alternative for hull design, capable of combining weight reduction, material efficiency and safety.

Understanding which elements are important when perceiving the goodness of a ship is crucial. Traditional driving factors, such as cost and value for money, have been augmented by additional ones, environmental issues increasing risks associated with rapidly changing commercial regulatory environment. In this paper, we propose ways these new to be incorporated in perception robust ship. We use complex systems engineering theory classify five aspects: structural, behavioural, contextual,...
