According to Christ (2014), ROVs in this classification are generally limited to seawater depths of less than 300 m due to the weight of the power delivery components and one atmosphere pressure housings, which imposes limitations upon the vehicle size. According to Teague (2017), historically, submarine exploration has been restricted to companies or organizations with considerable funds and resources. A ROV is not intended to be a replacement for diver investigations, but could serve as a substitute if divers are not available or diver safety is in question (NOAA, 2017), which is relevant in underwater blasting, due to the risks involving the use of explosives. [...]a methodology using low-cost observation ROVs has been developed to improve rock dredging to channel deepening, as shown in the methodology flowchart given in Figure 2. Approximately 6.5 million tons of cargo are transported annually through the waterway, mainly soy and corn, as well as sand, gravel, sugar cane, fertilizer, charcoal and other agricultural products (Moreira, 2016).
