Chapman Marine's Mission: Safeguarding Critical Infrastructure Below the Surface
Chapman Marine specializes in underwater inspections of critical infrastructure such as dams, power plants, and raw water intakes. Their primary goal is to identify and address issues before they escalate, ensuring the safety and reliability of these structures. Prior to incorporating ROVs, the company primarily relied on dive teams to gather critical information about underwater conditions. Now, they bring their Deep Trekker DTG3 and PIVOT ROVs to every job.
Enhancing Safety and Efficiency in Underwater Inspections: The Role of ROVs at Chapman Marine Inc.
Chapman Marine Inc., one of Texas’ trusted commercial dive and underwater construction companies, has revolutionized the field of underwater inspections by incorporating Remotely Operated Vehicles (ROVs) into their routine operations. In this case study, we will explore how Chapman Marine utilizes ROVs to enhance safety and efficiency during pre-job, routine, and emergency inspections. By doing so, they have not only reduced costs but also improved the quality of deliverables and safety for their team and customers.
The Challenge of Underwater Inspections
Philip Wolfe, General Manager at Chapman Marine, highlighted a recurring challenge in their operations: "We get the information that there's a problem down there, we know we've got an issue, but we don't know what it is."
Often, their team receives limited information about underwater issues, making it difficult to assess risks accurately. This lack of clarity poses a significant safety hazard for divers. Ultimately, the ROVs are much faster, safer, and easier to deploy than a diver.
The Solution: Leveraging ROVs for Comprehensive Underwater Inspections

A Closer Look Before the Dive: ROVs Enhancing Safety in Pre-Job Inspections
Before diving into the water, the team uses the limited information received from the customer to develop an initial understanding of the situation. This helps them gauge the safety risks involved.
“We use the ROVs to develop an understanding before we put divers in, to help us understand the safety risk before getting in the water,” Wolfe explains.
Streamlining Routine Inspections: ROVs' Efficiency in Action
ROVs are deployed for routine inspections, especially in confined spaces or areas requiring penetration. These inspections are completed in a fraction of the time it would take a dive crew, saving both time and resources.
“In some circumstances,” says Wolfe, “we use the ROV as the primary solution for certain inspections in areas where there's confined space or where we have to go into pipes or something like that, where it would take an entire day and a large crew to load out just to do the inspection, and we can do it in a few hours with the ROV and get the information that we need.”
Responding Swiftly to Emergencies: ROVs in Critical Situations
In emergency situations where immediate action is required, ROVs provide essential situational awareness. It’s dangerous to put divers into a situation where hazards aren’t entirely identified. Divers can be exposed to unknown dangers, making ROVs invaluable in understanding the situation better.
“We won't know all the safety issues. The ROVS help to develop the situation and we're often able to back off the urgency a little bit to say, ‘Here's the video. Here's what we understand. This is what we see is going on’. Then we pass that off to engineers, and make some recommendations so that they can develop that situation. So that's helpful for us and we're able to satisfy that gap in understanding in an emergency that often happens. It makes owners very uncomfortable, not knowing what's going on, and they want it fixed yesterday. So, it gives us some time to develop a better plan and then get out there and get after it.”
ROVs vs. Tripod Mounted Sonar: A Paradigm Shift in Underwater Inspections
Wolfe explained their preference for ROVs over a tripod mounted sonar (the current standard in the Gulf of Mexico for the oil industry that's used offshore when mapping and inspecting underwater assets), emphasizing the quick access ROVs offered to inspection sites. Tripod mounted sonar systems, while capable of producing high-quality images, required additional equipment and were less versatile.
“So, that was why we went with the ROV versus just a tripod mounted sonar, because of its very quick access to the site, where the tripod mounted sonar requires additional equipment to get there because it's not mounted to anything. It's a tripod, you need a boat and crew, you drop it down, and it sits on the bottom. You get a beautiful picture, but to get that beautiful picture, you have to have all that other stuff, and you have to have access to that point,” Wolfe illustrated.
“The limitations of a tripod mounted sonar is that it's not attached to an ROV, that it's not a two-man crew, and you have to have a boat. If you want GPS, you have to have that receiver attached to a boat. You have to do all this setup, which any GPS is going to require. I can't take a tripod mounted sonar with two guys and go 400 feet away from the shoreline when there's an issue on an intake or a dam or something. We need to have a place to launch, and all of these things that require additional equipment - which we have, but, It takes longer, it's more expensive, and a lot of times we just don't have direct access to the water - unless you're bringing ladders or you're doing a heck of a lot of work to get down there. If you're gonna do all that work, you might as well put a diver in the water.”
ROVs in Action: Unveiling the Triad of Safety, Efficiency, and Quality
Chapman Marine has experienced numerous benefits since incorporating ROVs into their operations:
Safeguarding Lives and Insights: How ROVs Prioritize Safety
ROVs significantly reduce the risks associated with underwater inspections. Divers are no longer exposed to unidentified hazards, ensuring the overall safety of the team. “Anytime a diver enters without visibility, they are exposed to a risk that they don’t need to be if we run an ROV.”
ROVs: The Turbocharged Engines of Inspection Efficiency
Routine inspections that once took a full day to mobilize and deploy now require just a few hours with an ROV pilot, resulting in substantial time and cost savings.
Delivering Clarity: ROVs and High-Quality Customer Communication
ROVs provide high-quality video footage that can be shared directly with customers. This not only improves situational awareness but also allows customers to identify issues firsthand. “Visualization is the most important part of analysis,” explains Wolfe.
Comprehensive Reporting: The Cornerstone of Effective Inspections
After every inspection, whether performed by ROVs or divers, Chapman Marine produces comprehensive reports with videos, pictures, and descriptions of the work performed, and issues recommendations.
“When you're looking at the reports that we're putting together, what is good to decision makers, you're talking about the highest echelon of whatever organization that we're working for, and sending them a link to a video. They're not watching the video. They want a one to two page report that has a picture with a description. When you look at the executive level of making decisions on a project that we're working on, that's the type of report that we put together. It needs to be simple and very clear: ‘Here is what it looks like. Here's what your problem is.’ It is very helpful that the ROVs make producing reports very easy.”
A New Era of Collaboration: ROVs Enhancing Customer Engagement
Chapman Marine recognizes the importance of involving their customers throughout the inspection process. By utilizing ROVs, they can have their customer's eyes directly on live ROV surveys, aiding in issue identification. This customer-centric approach improves communication and helps solve problems more effectively. Previously, they had divers entering low visibility environments with regular cameras, or describing the situation for post inspection with hand drawings.
“The customer knows the original problem better than the divers. With an ROV video, we can have their eyes directly on the live ROV survey and can better identify issues rather than relying on diver descriptions. With ROVs we can get there fast, get the information, and get it in front of more eyes, quicker, to better solve the problem.”
Deep Trekker: The Game-Changer in Underwater Inspections
transforming their approach to safety, efficiency, and customer satisfaction. ROVs have become indispensable tools that not only reduce costs but also enhance the quality of deliverables and the overall safety of their team. As Philip Wolfe succinctly puts it, "It's all about how to tell the customer what is happening," and ROVs have become their most valuable means of communication in the underwater inspection field.
When asked what he likes most about utilizing the Deep Trekker ROVs:
“Previous ROVs we have used required a lot of set up and programming that we just don’t have time for. With a Deep Trekker, I can plug it in and it’s ready to go, you do all the updates, and I can give it to somebody, give them some training, and then they can go out and execute.”
It's not a science project every time we try to pass it off to somebody.
So that's really what I'm looking for. I don't need a project. I've got enough projects. I just need something where I can take this and put it in the water now. I understand it takes work, there's a little bit of work, like building a report takes work, but there's different levels of work and there's a threshold at which I'm willing to go up to. But once it surpasses that threshold, it's just too much for us because it's too time consuming," explains Wolfe.
When asked why he stays with Deep Trekker:
“So, I will tell you, customer service for me is big. We're willing to pay a little bit more to have customer service because, in the end, that means saving time and money for us when we run into an issue - and that goes across everything that we do, whether we're buying a new engine for our boats, or whatever it is. We changed manufacturers for all the motors on our boats because there wasn't service for them. They're great motors, but no service doesn't help us. That's important, and I do like the updates. Deep Trekker just adds some additional capability to the ROV that you already have, to increase the functionality of the system. It’s awesome.”
