REFRESH Decision Support Tool - video presentation

REFRESH 3rd workshop - February 27th 2015, Monaco

posted 12 May 2015, 01:27 by Giorgio Leone   [ updated 12 May 2015, 01:35 ]

The final workshop in Monaco took place at V.Delta premises on 27th of February. Information about the programme and possibility to attend the workshop online was delivered to a number of companies. It was finally attended by representatives of project partners, V.Ships officers and, through Webex, representatives of other maritime companies, such as Vicus and Ghenova (both engineering companies), Aimen (Research Centre), Balina Group (supplier specialized on propulsion), STX (shipbuilder) or SeaEurope (the European Ships and Maritime Equipment Association).
Presentations consisted on concept proposed workflow for future applications of REFRESH project investigated approach.
Such workflow covers all steps from receipt of plans and arrangements, through energy audit and on-board systems modelling till necessary simulations to assess financial viability of the identified energy saving solution(s).

A set of specific case studies focusing on the vessel types taken into consideration during the project (Bulk Carrier, Tanker, Containership, ROPAX) were introduced. It included the application of the DST to one of the ROPAX vessels made available by one operator partner in the project.

Particular attention was paid to the REFRESH Decision Support Tool (DST) developed during the project, like in the two previous workshops. The testing results after using energy models and actual live data from vessels were also introduced and discussed by the attendants, both live and online.
After the presentations, a discussion followed, quite interesting in view of the future potential massive application of energy modelling approach for energy performance assessment and improvement.

Attendants agreed on the fact that there is an obvious drawback, constituted by the amount and the reliability of the required operational data to be used for set up and benchmarking of the simulations.
One of the conclusions was that such in deep analysis (dynamic energy models built component by component) seem to be feasible for existing vessels only when looking into specific systems where low energy performance was already identified (i.e. either by direct ship-owner experience based feedback or energy audit finding or even a first less detailed energy modelling based analysis). Thus, based on the project experience, the DEM full application to ships looks more promising on new-builds. This applies particularly to new ships built in Europe, thanks to the more complex average vessel type and also to the presence of shipyards already familiar with monitoring and advisory systems (e.g. Meyer Turku, within REFRESH Consortium), which are mainly developed in Europe (e.g. one of the leaders in the business sector is ENIRAM, again part of REFRESH Consortium) .
Back to existing vessels application, it was agreed that the challenge is not anymore to be able to model, simulate and advise properly on room for savings based on proper energy performance related data; now the real challenge is to take such a work to low budget, poorly equipped, very simple ships, which are still today the majority of all the vessels sailing.
Thus, in such background, in view of improving operational efficiency and also properly identifying and also financially assessing retrofit solutions, it is suggested to use REFRESH project tools and results to develop and offer to the shipping market a step by step advisory product. But this product will require proper data input, hence investment on on-board measuring tools. Such cost could be afforded only based on room for savings previously identified through a simplified analysis, adapted to the available level of information and targeting to identify where the deficiencies are and only roughly calculate possible savings. The following step, endowed with further detailed models, should be then implemented based on the previous promising results (see picture below).

NAVALIA 2014 - REFRESH project 2nd workshop

posted 12 May 2015, 01:11 by Giorgio Leone

The Refresh workshop in Vigo was implemented during the 3-day Navalia maritime fair and exhibition (http://www.navalia.es/en/), (May 20th to 22nd) which was attended by some thousands people from all over the world. The workshop was hosted by the AuxnavaliaPlus Project (led by GAIN and co-funded by the Interreg Programme-Atlantic Area) in their stand in the exhibition, and announced to all visitors through their activity programme.
In addition to the workshop, information about the project was permanently offered to visitors at the stand. The project info presented consisted on updated versions of the presentations delivered at MIBE and in front of a different audience, as the exhibition was mainly visited by managers, operators and other representatives of the whole maritime supply chain industry
Special relevance was given to the advances made in the Decision Support Tool specification.

MIBE 2013 - REFRESH project 1st workshop

posted 12 May 2015, 01:02 by Giorgio Leone   [ updated 12 May 2015, 01:07 ]

Held on November 27th 2013, the event took place during the Maritime and Innovation Brokerage Event (MIBE 2013), and was attended by more than 100 people. Both, MIBE and the project workshop, were organized and hosted by GAIN in Santiago de Compostela (Spain).
REFRESH dedicated session (http://www.maritimebrokerageevent2013.org/?page_id=1417) addressed the aspects of vessel retrofitting that are essential for improving the energy efficiency on-board.

During the Santiago workshop, the developments of initial stages of the project were detailed, starting from the energy audits conducted on-board 6 ships in order to identify energy performance related deficiencies and applicable solutions, called Energy Saving Potentials (ESPs), and to collect useful data for the vessels’ energy models preparation.

Particular attention was paid to demonstrating of the energy models, as they constitute the basis for optimization, monitoring and decision support developments. As an example of the application of the energy models, a reliable model for simulating the discharging procedure of an AFRAMAX tanker was presented and discussed. Developed on the basis of the experience and numerous real data provided by a tanker operator, the model is capable of simulating discharging procedures, allows estimating various parameters related to the procedure and enables realistic optimization of discharging operations.
