Our submarine cable installation professionals are proficient in all phases of submarine cable-laying operations. Our project engineering, planning, and execution methods are based on extensive experience, best management practices, and proven techniques. In addition, Marconserv invests heavily in modern, state-of-the-art technology and equipment that surpass industry standards for safety, quality, and efficiency.

Marconserv specializes in dock structures ranging from dry and liquid bulk terminals to heavy-lift docks and cellular structures. Our expertise also includes the mooring and fleeting structures needed to maintain an efficient operation. Whether you are building a new dock or extending the life of an existing facility, we can provide a wide variety of services that will optimize the efficiency of your facility.

Since Marconserv began in the early 1900s we have been building deep foundation structures to support electrical towers, buildings, bridges, and more. This includes cellular structures, Open Cell速 structures, reinforced seawalls, and cofferdams. Whether this be from the water, or on land, we can create a customized approach for every project.

Dredging promotes efficiency as much as a well-functioning terminal does. Marconserv can provide both mechanical and hydraulic dredging options that will maintain the needed depths for efficient navigation. From mass removal to surgical dredging, we have the ability to right-size our operation for your project needs. This includes projects that may involve rapid dewatering and disposal in offsite locations.

We can provide several choices to help you understand the conditions of your structure below the waterline. These options include high quality dive inspections with experienced certified commercial divers, underwater acoustic imaging, and high-resolution multi-beam hydrographic surveys. Each one uses the latest technologies to collect data and create the detailed information that you need to monitor your structures.

Marconserv divers can place concrete, weld, cut, grout, dredge, and accomplish whatever else may be required to keep your structure in good condition. Using divers will eliminate the added cost of an expensive cofferdam structure, and can often truncate the project schedule. Our divers specialize in zero-visibility conditions and use state-of-the-art equipment to carry out quality repairs safely.

Marconserv's extensive bridge construction experience will insure your new structure is built to the highest quality, on time, and within budget. Whether it is a new structure, or the repair of an existing one, our ability to provide both above-water and below-water construction services can lead to additional cost-saving options.

Marconserv maintains a solid inventory of equipment for re-laying pipelines and is constantly upgrading. The key to efficient trenching operations lies in providing a well-designed nozzle skid with an effective deployment and recovery system and efficiently delivering large volumes of high-pressure water and air.

Large fleet of marine equipment is suited for all types of marine construction projects. From our barge mounted heavy pick cranes to our fleet of high-quality portable barges, work flats, john boats, amphibious dump trucks, and portable tow boats, we are equipped to address all of your marine support needs. Our vessels are USCG inspected and are operated by licensed pilots.
