“…Furthermore, it is reported in [15] that a shovel can have 15 % regeneration during each operation cycle in average. While an accurate estimation of the regenerative braking energy for a seafloor vehicle is out of scope of this paper, according to [16], the regenerative braking energy of a thruster in water is half of its value in air. It can be concluded that in pressurized subsea environment, the regeneration energy would be even less than that.…”

The main goal of this paper is to give a framework for designing the power distribution system for seafloor mining vehicles operating in deep and ultra-deep waters. As the starting point prior to the design, the tethered seafloor mining vehicles are compared with their counterparts in the terrestrial mines and the well-developed remotely operated vehicles. Then, various power distribution alternatives are studied and compared taking into account the main design criteria such as efficiency and size of components. Although the major loads of these vehicles are AC motor loads for drilling, pumping and locomotion, it is concluded that the DC distribution, both in topside and subsea sections, is the best option. Typical values for efficiency and volume grades (normalized values) for the major components in the distribution system have been considered in the calculations.

“…The distribution systems mounted on ROVs are either AC or DC and the transmission voltage is usually MFAC (400-800 Hz) [16][17][18][19] or DC [20]. In [19], AC, DC and MFAC distribution system has been compared for a 100 kVA ROV with a 10 km long cable and their advantageous and disadvantages have been listed.…”

“…Some of these are: to minimize the size of the cable, maximize power transfer to the ROV, minimize system cost, minimize ROV weight and maintaining a high level of electrical power quality. Of course, many of these design requirements are not independent of each other so optimizing one can minimize the other [9], [10]. From the perspective of protection and cable lifetime, over voltage (OV) and over current (OC) conditions pose the greatest threat to the cable and system lifetime [11].…”

In the past decade, the significant improvements in high speed, high voltage transistor technology enabled the design of more sophisticated sub sea electrical power transmission systems. This is the case of the power-electronics-based single wire DC and high frequency AC transmission systems that appeared as alternatives to the traditional three phase transmission systems. Although such advanced alternatives have been employed on a scenario basis, no thorough study comparing these different options has been carried out. This paper aims to examine 50/60Hz AC, DC and high frequency AC electrical transmission systems regarding their technical and financial advantages and drawbacks, through steady-state and transient analysis of a 10 km, 100kVA ROV.

Purpose -Proposing a fuzzy multi-criteria decision making (MCDM) algorithm that is able to incorporate the heterogeneousness effect of DM group into the decision process, in order to determine the best remotely operated vehicle (ROV) design alternative to manufacture and developing a practical decision aid tool based on this algorithm. The paper aims to discuss these issues. Design/methodology/approach -An algorithm utilizes fuzzy AHP Buckley's approach for modeling heterogeneousness of the DM group, fuzzy AHP Chang's extent analysis to calculate the priority values of criteria and Chen's fuzzy TOPSIS for ranking the alternatives and finally group working technique for initiation issues is developed. MATLAB is used to implement the algorithm and generate a decision aid tool. Real life application and sensitivity analysis is performed by the help of generated tool. Literature and background explanations are also provided. Findings -A MCDM algorithm that incorporates the heterogeneousness effect of the DM group into the decision process is introduced. Sensitivity analysis suggested the independence of the final result from DM group and criteria set. A practical decision aid tool is generated for ROV manufacturing companies. Practical implications -A computerized MCDM aid tool that incorporates heterogeneousness of the DM group into the decision process is generated. Tool let ROV manufacturing companies to evaluate ROV design alternatives with respect to qualitative and quantitative criteria and determine proper choice. Originality/value -Determination of the proper ROV design alternative to manufacture gap within the literature filled with an algorithm that provides more reliable results due to its incorporation the heterogeneousness of the DM group into the decision process characteristic. A practical decision aid tool is generated.
