Marine Engineering


Marine Engineering Consultancy & Support

Add decades of experience to your project. Our marine engineering consultancy service is a valuable aid to any underwater construction, inspection, or repair project, at any stage. Midco's highly skilled dive teams have extensive experience providing engineering support during the planning stages, ongoing construction, structural inspection, and repair.


Our marine engineering consultants are available for the early planning stages of diving related projects. We can assist with all stages of the planning process. We're available to guide our clients in meeting safety compliance and requirements of various government agencies, such as the Occupational Safety and Health Administration (OSHA), MSHA, the U.S. Army Corps of Engineers, and the U.S. Department of Energy.

Site Eval & Building Specs

With a survey of the intended build site, Midco can review, propose, and make recommendations for improvements to be made before construction begins. From conceptual development and detailed engineering analysis, to making recommendations, constructability reviews, and cost evaluations, we can help you move fluidly through the planning process and on to construction.

Hazard Analysis

If you want it done right, you better know what you're up against. You need an accurate projection of all hazards associated with the intended engineering project. Our team will conduct a thorough analysis of the site and uncover any and all dangerous elements to be considered before the project begins.

Dive Plans

Our underwater engineer support can provide a predetermined dive plan to ensure the success and safety of the phase of construction taking place beneath the surface of the water. A comprehensive dive plan will detail the processes undertaken by the commercial dive team and put your mind at ease about this portion of your project.

Ongoing Inspection

Midco’s fully certified and insured dive teams perform inspections of underwater and marine construction projects to provide quality assurance and as-built verification during all phases of work, including the ongoing construction phase. As consultants, we offer support throughout the duration of the engineering project, from conceptualization to completion.


At every step of the way, Midco collects detailed documentation of the team’s findings in order to ensure our clients and other contractors have the most accurate and timely information. Our documentation is a comprehensive collection of underwater photography, underwater video, written documents, and reports.


Because we work in such extreme conditions, certifications are just the start. We start with the best of the best, and if we're not diving, we're drilling, retraining, and recertifying.


Commercial diving requires a special skill set: tradesmen who welcome the added challenge of working underwater, in some of the most demanding conditions on the planet. After nearly twenty years, we have what it takes to assemble the right team for your job.


Midco is the leading commercial diving operation in the United States because we go in where few others would. Our commitment to safety, process, and protocol gets the job done. In such harsh and challenging environments, experience makes all the difference.


At Midco Diving & Marine Services, we take on the toughest underwater conditions you can imagine. After nearly twenty years of commercial diving experience from underwater construction to municipal water tank repair – we’ve gone in where few others would even think. Highly contaminated water, confined work spaces, radiation, zero visibility, and high-altitude operations are all fair game. Whatever you’ve got in mind, we welcome the challenge.
