This paper presents the underlying method of a proposed digital twin for proactive production planning. We derived the method based on a requirements analysis considering the challenges in maritime production. Using real-time production feedback data, alternative production scenarios are identified to prevent disruptions and delays in manufacturing and assembly. As part of the ProProS research project, the method is implemented and validated through the development of the digital twin, which offers a platform for the realization of further use cases to be diffused into industrial applications.

The methodology presented in this work considers an impact’s available kinetic energy as balanced by the ice crushing energy as well as the structural deformation energy. The algorithm re-calculates the kinetic energy iteratively by subtracting the energy lost to structural deformation and ice crushing at specified time-intervals. The updated kinetic energy is then used to determine the current impact speed, which controls the indentation rate of ice on the structure. The result is a contactless ice load model which is intrinsically coupled to structural deformation. Accounting for structural deformation energy is important for overload of Polar Class ships, as well as any ice impact for non-ice class ships.

The author has previously investigated production of hull structure in steel, aluminum and titanium with application to a large, fast naval sealift trimaran and monohull. Reduced lightship weight, of which hull structure is generally the most significant component, will accommodate a greater payload or allow for a smaller vessel for the same purpose. The results of those studies are applied herein to a wide range of commercial vessels with hull material of steel, aluminum, titanium as well as FRP and ferro-cement. Consideration is given to identifying the most advantageous hull material. The variables considered are years of service, payload, fuel consumption, maintenance, vessel size and cost. The results are presented on the basis of a measure of merit as a function of these characteristics.

The speed/power performance of a ship is nowadays not only a contractual, but also a statutory requirement. Thus, it is essential to know the true speed/power performance of the ship, as verified by conducting sea trials before the delivery. Presently, relevant guidelines of the International Maritime Organisation (IMO) include two alternatives for the verification of the speed/power performance of a ship in relation to the calculation of a ship’s Energy Efficiency Design Index (EEDI), namely, the ITTC Recommended Procedure 7.5-04-01-01.1 Speed and Power Trials: 2017 and the ISO 15016:2015 procedure, while noting that ITTC recently revised its recommended procedure and the same is underway for the ISO 15016. In this paper, we will re-analyze the sea trial results of a series of tanker sisterships tested under different conditions, by applying the newly updated ITTC procedure to assess the actual speed-power performance of the ships. In particular, the influence of applying alternative methods in analyzing the sea trial results and the effect of environmental conditions on the achieved speed performance are investigated. The results are very important for many stakeholders of the maritime industry, especially for designers in developing new EEDI compliant ships, for shipbuilders and for shipping companies in planning their new buildings and retro-fittings in view of the implementation time frame of EEDI/EEXI.

Quiescent Period Prediction (QPP) purpose is to provide ship motion conditions and motion predictions with sufficient forecasted time to launch, recover, and complete other motion sensitive tasks regardless of the seaway. QPP operates within a federated architecture system containing measurement instruments such as a Wave Radar system used to map remote sea surfaces several hundred meters in advance of the ship. This enables the computation of future wave forces acting on the vessel. This article describes the development of the QPP System concentrating on test procedures, timely seaway mapping and ship motion characteristics to complete specific motion sensitive task.

Underwater noise is a growing concern for commercial vessels. As an example, efforts are already underway to reduce underwater noise and related impacts to Southern Resident Killer Whales (Orcas) in the Pacific Northwest. Groups like Transport Canada, Maritime Blue, Port of Vancouver, and others are investigating appropriate noise limits for vessels and strategies for ensuring noise levels are reduced. With this, there is a strong desire to identify treatments that can reduce underwater noise on existing vessels. Numerous “menu-style” lists of potential treatments have been compiled, but deciding which treatment to use is not trivial. Underwater noise reductions generally cannot be achieved through selection of a single treatment from a catalog. Rather than selecting treatments from a list, stakeholders should look to reduce underwater noise by choosing the right design approach. This approach would ideally be applied during design and construction phases, though post-construction design approaches can also be applied for existing vessels.

This paper addresses some of the wider issues in the design process for complex vessels with regards in particular to the design of naval ships and submarines. The presentation is given from the perspective of a British naval constructor, who spent the second half of his career teaching and researching into the design of complex vessels. This is presented to SNAME drawing on parallels with US Navy design practice from the author’s personal involvement in the design history of many of the designs that were built for the Royal Navy. A large number of the author’s publications have not been exposed directly to a SNAME audience so this paper compares and contrasts UK practice with that revealed particularly in the publications of the former Technical Director NAVSEA –Robert Keane – and his several co-authors. The paper’s title is deliberately contrived in its alliteration commencing with a phrase taken from an early critique of systems engineering by an eminent British naval constructor, querying whether systems engineering could provide the philosophical basis for modern naval ship design (NSD). The third “B” is considered to be a key technical characteristic in designing such complex systems, that of achieving a balanced design. In this regard the paper questions why the other major stakeholders in NSD, including collaborating engineers other than naval architects, seem to have such difficulty in appreciating the nature of ship design, particularly in the crucial early stages when most critical design decisions are made. The author draws upon a major paper published in 2018 in the RINA Transactions together with its written discussion by Robert Keane among others. A major point made in that paper is that not all designs follow the same process – in fact every new design is different and therefore the applicability of any process needs to be challenged. However, the intent of the current paper is to go beyond the largely technical argument of the 2018 paper by addressing the wider “fuzzy” half of ship design, in particular regarding the environment in which such “sophisticated” design is undertaken. Furthermore the consequences for the resulting vessels from such a constrained and often fraught process and professional practice are relevant to achieving the final complex design entity. The paper concludes by considering essential design engineering demands can be balanced with the pragmatic necessities of the design practice driven by the imperatives of the wider design environment and engineering practice. This consideration draws on not just the many and varied naval vessel projects the author has been involved in but also the subsequent research activities in the last two decades at University College London, where the UK naval constructors are trained in ship and submarine design.

The preliminary design phase of a ship acquisition program offers an overwhelming number of possible design configurations of which only a small number can be thoroughly developed by an experienced design team. This creates serious program risks, particularly when designing a ship that is fundamentally different from prior ships, such as an unmanned vessel. Set-based design offers a solution to this problem by separating functional disciplines into discrete sets that can be efficiently analyzed in parallel with one another. However, this process is still typically performed by teams of subject matter experts (SMEs) who are expensive to utilize and are potentially biased by past experiences or conventional thought patterns. The Serco Maritime Engineering Operations team has developed a new suite of software tools which attempts to improve upon a set-based design process by automating the generation of design points within each functional set. This software may be utilized in the first stage of any ship design program to provide the design team a high-level overview of the available design space by generating a large quantity of design seeds which can then be used as starting points for SMEs to develop ship concepts using conventional means for detailed trade studies and exploration.

The pattern of seaborne trade and goods transportation is changing and ships need to adapt to changes of customer and market requirements, cargo volumes, and new legislation for the safety of ships and nowadays, even more, to the strict regulatory requirements for the protection of the environment. Responding to the urgent needs for substantial reduction of GHG (Green House gas) emissions from marine operations in line with the ambitious targets set by the International Maritime Organisation and the European Commission, a series of research and development works were initiated in the maritime sector for the ships designed and built today and be operating in the next decades to meet future environmental requirements. Responding to these needs, the recently completed Horizon 2020 European Research project – HOLISHIP – Holistic Optimisation of Ship Design and Operation for Life Cycle (2016-2020) has developed suitable tools and software platforms, as necessary for the creation of innovative design solutions meeting the set low emission strategic objectives. The present paper is presenting the HOLISHIP, multi-objective optimisation approach to green shipping and demonstrates a subset of its functionality by two green design RoPAX case studies.
