Integrated Ship Design

Today ISD lab starts the TUGA (Escort Tug Gas Propelled) project, founded by Regione Autonoma Friuli Venezia Giulia within the POR-FESR 2014-2020 framework. The ISD lab will develop the project in collaboratin with two partners: Maarine Engineering Services S.r.l and Engys S.r.l.

The escort tugs operates in restricted waters, providing help to other ships. During escort operations, the tugs not only provide towing but contribute to the maneuvering capability of the assisted ship. Recent IMO rules fixed a road-map to lower the emissions of pollutants. In this framework, it is expected that all the ships operating in ports will be fitted with devices to lower the emissions or, alternatively, with a gas-fueled propulsion system. The adoption of LNG as fuel guarantees no SOx emissins and a remarkable reduction of NOx, CO2 and particulates emissions. In recent years, LNG propulsion systems have been already adopted on several types of vessels. However, such a technology was not widely applied on small crafts due to a reduced availability of small gas engines and due to the spaces required by gas containment system onboard. These matters drive to the need to study new technologies for onboard containment system as well as to develop a new optimized arrangements and hull forms. TUGA project has the aim to develop a new safe and reliable escort tug design, propelled by LNG. The escort capability will be assessed for heavy weather through CFD (computational Fluid Dynamics) simulations validated with experimental model tests. A model will be develop to extend the results to other hull forms helping to move towards a new generation of safer and eco-friendly escort tugs.

On July 26, 2018 the Integrated Ship Design laboratory (ISDlab), of the Naval Engineering section of the Department of Engineering and Architecture of the University of Trieste, together with the Cantiere Alto Adriatico Custom and Friulinossidabili, both partners of the ZELAG project (Zero Emission navigation LAguna di Grado), presented the results achieved with the project to a large audience at the Laguna Palace Hotel in Grado. The ZELAG research and development project, co-funded by the European Regional Development Fund, is part of the Maritime Technologies (POR FESR 2014-2020).

The presentation of the results was opened by the MareFVG Maritime Cluster Chairman, Claudio Kovatsch, who congratulated with the entire partnership for the idea and the development of the entire research project; he hopes the production of many other electric powered boats in the near future. Afterwards there were the greeting speach of the mayor of Grado, Dario Raugna, and the councilor for tourism of Aquileia, Alviano Scarel. The technical report was presented by the main players of the project: Alberto Marinò, Carlo Nasso, Francesco Mauro and Ubaldo la Monaca (for the University of Trieste), Odilo Simonit (for Cantiere Alto Adriatico Custom), Paolo de Clara and Chiara Bettuzzi (for Friulinossidabili). The speakers described in detail all the key features of the project starting from the initial objectives and demonstrating their achievement through the results of sea trials carried out with the prototype boat.

ZELAG proposes an eco-sustainable boat for the public transport of people through the inland waters of the Grado lagoon. A wooden prototype with hybrid-electric propulsion was built to guarantee a high reduction in radiated noise and pollutants emissions. The hull shapes have been studied to minimize wave pattern in order to safeguard the lagoon ecosystem. The boat purpose is to provide tourist transport services between the municipalities of Grado (GO) and Aquileia (UD), fullyintegrated within the regional slow-mobility network. During design phases, due attention was paid to the removal of architectural barriers, guaranteeing the boat usability even for passengers with reduced mobility.

Luciana Grimani, representative of the Higher Education and Research Service of the Regione Autonoma Friuli Venezia Giulia, closed the presentation, highlighting her full satisfaction concerning the fruitful synergy between the academic world and the business world.

At the end, all the participants were able to visit the boat docked on the quay facing the event hall, and assist to a brief maneuverability test.

Today, March 8th, the new “Integrated Ship Design Lab” was inaugurated as result of the agreement between the Department of Engineering and Architecture (DIA) of the University of Trieste, Fincantieri and Intergraph Italia, part of Hexagon group. It is a multidisciplinary space unique in Italy. Fincantieri donated 12 last generation workstations and Intergraph just as many licences of Smart Marine 3D software. The Laboratory will be used for research activities concerning instruments and methods for integrated ship design, for activities involving third parties (relationship with partner companies and training of specialists), and educational purposes, providing to marine engineering students of the University of Trieste the knowledge of the most innovative technologies for ship design and the training for the usage of the associated IT systems. The improved skills of the students will grant a competitive advantage for the industries where they will be employed.

The Integrated ship design is a new methodology able to take into account all the requirements and constraints since from the early stages of design process. This approach assures developing a final product functioning, technologically adequate, and economically effective. In this contest, all the fields of naval architecture and marine engineering are involved together with several other disciplines. They have to be combined in order to obtain the best possible synthesis. This interdisciplinary approach stimulates the collaboration of many excellences from the local academic institutions and it is leading to new interesting collaborations. In the last years, many research groups have been studying new approaches on marine plants, structures and hydrodynamics. This knowledge will be deepened with the help of the new instruments of ISD Lab leading to the definition of new methodologies and procedures to improve the design of even better ships while saving time and reducing the costs.

ISD Lab is involved in summer modules dedicated to high school students, in order to help them in make the proper decision about their future. Alberto Marinò and Vittorio Bucci are holding a course titled: "How a ship is born: from the idea to the building". The main objective of the module is to make students understand how and how many activities should be coordinated and carried out to reach the physical realization of a ship. In fact, the ship is a complex machine, requiring high reliability and safety, as well as functional performance that may vary depending on operational requirements. Therefore, it is necessary to conceive of a synthesis result that involves different disciplines, which must interact synergistically and effectively.

This message will be transmitted by illustrating, with the help of virtual reality and 3D representations, examples of naval vessels (cruise ships, cargo ships, military ships, submarines, yachts, sailboats etc.) which are characterized by different service requirements.

The main arguments of the course are: the evolution of vessels, the external appearence of the ship, the internal arrangement, the ship design process, the shipbuilding process.

Vittorio Bucci and Ubaldo la Monaca take part to iTec 2017 conference in chicago to present the paper "Early-Stage Design of Integrated Power and Energy Systems for naval vessels electrification: advanced modeling using CSI". ITEC is focused on components, systems, standards, and grid interface technologies, related to efficient power conversion for all types of electrified transportation forelectric, hybrid electric, and plug-in hybrid electric vehicles (EVs, HEVs, and PHEVs) aswell as heavy-duty, rail, off-road vehicles, airplanes and ships.

The paper is the result of a collaboration of two laboratories of the university of Trieste ISD Lab and EPGC Lab with the Italian Navy devoted to develop the new certification standards for navy electric plants. Inedde, the naval vessels electrification is one of the most important issues to be tackled, because not only it allows a more efficient operation, but also is considered a technological game changer. Indeed, electrification offers improved operational benefits and enables mission systems continuous upgrade. Several technologies can be used, each presenting different impact on ship performance. Thus, instruments to analyze and compare different designs must be used already during early-stage design, allowing an aware and reasoned selection. In this paper, a Computer System Integrator (CSI) software is presented and an application example is given, about the electrification of a naval logistic support ship.
