The Ship Design Consulting Services, by ROMV & Associates, provides scientific and economic feasibility evaluations of ideas and proposals to solve problems onboard and out, ranging from the analysis to the development of solutions for vessels and other marine & riverine installations. For each situation, ROMV Ship Consulting Service covers the research to identify new applications for existing engineering system and develop innovative solutions to bring to market. Depending on a customer's needs, ROMV Ship Design & Consulting can provide these services as integral elements of the design process or as independent studies. Scientific & Consulting expertise of the group includes:
Shaft Consulting Services
Shaft Calculations is offered by the group and asses the clients in the appropiate techniques used are reach the goals and purposes commonly pursued while aligning shafts in vertical and horizontal plane at ships under construction or in course of repair. The services produce data to control alignment parameters for every stage of the alignment procedure as existing technical standards require.
Composites Consulting Services
Laminated Composites Analysis is offered by the group and asses the clients according to classical laminated plate theory. Input consists of ply material properties, material strengths, ply fiber orientation and stacking sequence, mechanical loads and/or strains, and temperature and moisture loads. Output consists of apparent laminate material properties, ply stiffness and compliance matrices, laminate "ABD" matrices, laminate loads and mid-plane strains, ply stresses and strains in global and material axes, and load factors for ply failure based on Maximum Stress, Maximum Strain, Tsai-Hill, Hoffman, and Tsai-Wu failure theories. A micromechanics report calculation is also included for estimating lamina properties for given fiber and matrix properties.
Structural Analysis Consulting Services
The Complete Ship Structural Design Process is offered by the group using FEA softwares, assesing the clients in projects where various materials are present either in new or existing structures and despite of the nature of loads.
Seakeeping Analysis Consulting Services
Seakeeping analysis is important in assessing the performance of floating structure in waves. To perform Seakeeping calculations, the wave characteristics as well as the response of the vessel are needed. The analysis normally requires reliable computer programs to calculate response amplitude operator (RAO) and accurate seaway representation. For seaway representation, theoretical spectra can be used but it is more preferable to use the measured spectra which can be obtained through full scale measurement. On the other hand theoretical spectra can be used for comparison. This consulting service offers a full-scale measurement of wave and vessel motions using data adquisition technology with boat motion monitoring system. This system is basically composed of a set of accelerometers, gyroscopes and wind sensors to be processed and analyzed using seakeeping formulations. Finally, the main analysis of the results obtained is in the form of spectral analysis of wave and vessel motions, from them the RAO can be obtained, which is the key to all Seakeeping decisions.
Engine Performance Analysis Services
The performance of the boat is the result of a complex interaction of all three aspects of the installation; the engine, the hull, and the propeller. Proper component sizing is very important to the life and performance of the entire propulsion system. There are tolerances in several aspects of the propulsion system, and in worst-case conditions the result can be short life and/or unsatisfactory performance because for instance the engine power may be expected to vary due to manufacturing tolerance by as much as 3% when it is new on either side of its rated or 100% power, or up to 40% when it is reconstructed on lower side of its rated. In the propeller case, the power absorption may be as much as 5% higher, or lower than originally expected when it is new or worst when it has already many operation hours. All these situations may point many operators to choose to operate at reduced throttle settings while cruising to reach its rated speed (rpm) when the boat is ready for sea but the engine life and economy have not the best results. The Engine Performance Analysis Service includes the evaluation of the fuel rate performance of a Marine Propulsion Engine, to the original factory performance specifications for that specific engine. This comparison is made for the entire operating range of the engine, and if the fuel rate data from the analysis test is within the acceptable range for load and performance specifications, it is an indication that the engine is operating correctly, and the propulsion system was sized satisfactorily. If, however, the actual fuel rate curve falls outside the acceptable range for load and performance specifications, adjustments and/or repairs for the fuel system may be necessary, or a further check may be needed for the hull, rudder, propeller, etc.
Dredging Consulting Services
From the very beginnings of civilization, people, equipment materials and commodities have been transported by water. Ongoing technological developments and the need to improve cost effectiveness have resulted in larger, more efficient ships. This, in turn, has resulted in the need to enlarge or deepen many of our rivers and canals, our “aquatic highways”, in order to provide adequate access Dredging for Navigation to ports and harbours, Dredging for construction, reclamation & mining, Dredging for the environment, Dredging for material management alternatives and Dredging for sustainable crowding relocation. For all these situation, ROMV Dredging Consulting Services offer the whole package to fulfill each requirement.
Marine Engineering Consulting Services
The various duties of the Marine Engineering Services relate to the operation of the ship in a safe, reliable, efficient and economic manner. The main propulsion machinery installed will influence the machinery layout and determine the equipment and auxiliaries installed. This will further determine the operational and maintenance requirements for the ship and thus the knowledge required and the duties to be performed by the crew and by the marine engineer also. As ships are larger and complex vehicles which must be self-sustaining in their environment for long periods with a high degree of reliability, this service cover the various systems which propel and operate the ship assessing all decisions in configuration layout, equipment calculation & selection, training & trials, maintenance and so on. More specifically, this means the machinery required for propulsion, steering, anchoring and ship securing, cargo handling, air conditioning, power generation and its distribution.
Other Consulting Services
An open group of engineers & masters of sciences working continuously on concept explorations, synthesis models, design of experiments, CFD testing and varied calculations covering the whole ship work breakdown structure. In some cases the group carry out own models and computational tools, in other cases adopt the software requested by the clients, but always to fulfil the requirements and deliver the final product in a better way. Also, a complete risk and decision analysis service is offered by the group to help clients answer questions as know the chances of making a project success in their next venture, Or which of many decision options is most likely to yield the best payoff? How about the best sequential drilling strategy? Or how much to invest in various projects in order to maximize the return on your project portfolio. Armed with that kind of information, you could take a lot of guesswork out of big decisions and plan strategies with confidence. As consulting services the group also has structured ship/yacht production process and maintenance process based on various activities as superintendent/ship/tenders planning system to easily browse through the jobs within the conversion/new construction/existing projects. This service needs the participation of ROMV professionals as consulting men to reach high productivity goals. Finally, the group has appropriated process specifically designed to assist operators safety departments with the requirements under ISM for health & Safety, providing total management of your ISM system when it is requested via LAN/WAN networks between office/shore and the vessel. This will greatly reduce the administrative headache with keeping your fleets ISM documentation up to date. A single export from an office system can be imported by your entire fleet.
