What Is Marine Construction?

Marine Construction Near Me is anything built along a body of water, such as bulkheads and seawalls. These structures help prevent damage to land located near the shore.

Marine Construction

Contractors who work primarily on ocean marine jobs understand the unique risks and need for customized ocean marine insurance coverage. But other contractors may not realize that even a small job with a marine component creates risk exposure and needs custom coverage.

Building platforms are a common construction method used in marine projects such as wind turbines, bridges, and marine buildings. These platforms are typically manufactured onshore before being shipped to the installation site in the open sea. This solution simplifies the process and enables people to work more easily in the open ocean. It also reduces the number of transportation steps needed for the materials and equipment.

Marine concrete structures need to be particularly robust in order to withstand the action of the sea and the forces that are exerted on them. Examples include wharves, piers, and breakwaters. Other structures that require a high level of robustness are wave-deflecting or energy-dissipating structures, coastal protection structures, lighthouses, and offshore oil rigs.

The most important aspect of the construction of these structures is the design phase. The use of computer-aided design (CAD) programs allows engineers to create and test their designs before starting construction, resulting in a more efficient process and saving time and money. These CAD programs can also be used to visualize how the structure will look once it’s completed.

In addition to using CAD software, engineers in the marine construction industry should ensure that their structures are designed and constructed in accordance with all relevant regulations and industry standards. This will help them avoid structural collapse and other safety risks on the job. Additionally, they should use appropriate tools, carry out regular inspections, and provide proper training for their workers.

Moreover, it is vital to report all incidents in the marine construction industry to ensure that they are properly investigated and resolved. This can help employers improve safety procedures, address workers’ compensation claims, and identify underlying issues. In addition, it can increase trust and communication between workers and employers.

In order to make a 3D visualization system work, it needs to be equipped with advanced hardware components and positioning systems. For example, a harbor dredging project may require a GNSS heading bundle, pitch and roll sensors, and a commercial-grade Wi-Fi connection. This information is continuously fed into the software, allowing it to show the current state of the project in real-time.

Underwater Structures

Marine structures include docks, bridges and tunnels that run underneath bodies of water. These massive, capital-intensive feats of engineering must withstand significant weather events and complex forces. They must also faithfully serve their function for decades or more.

Building underwater poses unique challenges, since many tools and materials work better when above water and dry. Marine construction workers use specialized methods and equipment to overcome these difficulties.

Builders often construct modular pieces of a structure offsite and transport them to the final site on barges. They then lower the piece into the sea or river using weights to keep it in place. This method reduces build time and allows builders to pump water out of the finished structure if necessary.

In some cases, builders construct temporary enclosures called cofferdams to allow them to work under the water. These enclosures prevent the water from flowing back into the construction site during the building process, and they keep marine life away from the area. Engineers build cofferdams from a variety of materials, such as welded steel, rocks or dirt. They sometimes fill the spaces between a cofferdam and the final structure with concrete or sand.

Piles, which look like long columns, provide a sturdy foundation for marine construction. They can be driven into the ocean floor with a powerful hammer, creating a strong and stable base for structures below the water’s surface or on the bottom of the seabed. They are used to create underwater and overwater foundations, wharves, oil platforms, bridge piers and even fully submerged buildings. Construction workers built the New York’s Tappan Zee Bridge with steel cofferdams.

Divers also repair and maintain underwater structures, such as dams, power stations, submarine bases, bridges, shipyards and retaining walls. In addition, they make repairs to sewage pipes, manholes, docks and pipelines. They may also sandblast and paint marine vessels to make them look good as they are repaired.

Some engineers have dreams of building cities under the ocean, such as a spiral that could generate its own energy and house 5,000 people, as well as withstand natural disasters like earthquakes and tsunamis. These futuristic, fantasy-like structures would require a huge investment, but they might not be too far off.


While bridges might seem like a simple construction, when building on water, there are many more considerations. Anytime something is built in the water, it needs to be designed to withstand constant water pressure and abrasion. Additionally, marine environments are corrosive and require corrosion-resistant materials. When building a bridge, the team needs to take all of these factors into account to ensure that it will last.

Marine construction often involves the use of structures located on or around bodies of water to facilitate commercial operations and protect surrounding shorelines. Commonly used structures include wharves, docks, piers, bulkheads, seawalls and revetments. These structures are important for facilitating maritime activities, protecting coastal areas and managing soil movement.

Another common aspect of marine construction is the use of bridges to connect islands or provide access to the mainland. These bridges can be used for pedestrian traffic, cargo or even vehicles.

Marine bridges are often specialized to meet specific requirements of the project. For example, they might be made from precast concrete to be strong and durable, or from wood to blend with the natural environment. They may also be constructed to accommodate a wide variety of vessel sizes and shapes.

Like all bridges, marine ones need maintenance and repairs over time. However, the nature of their location in the water means that this maintenance will need to be performed more frequently than a similar structure on dry land. This increased frequency of maintenance can cause a greater impact on the ecosystem as a whole.

Whether the bridge is being constructed over a river, ocean or wetlands, a professional construction company will carefully assess the environment to determine the best materials and design for the structure. This will help ensure that the bridge can be maintained and rehabilitated over the long term without causing too much disturbance to the natural habitat.

When working on a marine construction project, it is critical to have the proper insurance coverage in place. Contractors should contact a reputable insurance agency that specializes in this area of construction to get more information about the available options and how to proceed with getting coverage for their next project.


Marine docks offer access to watercrafts and a safe place for swimmers to enter the water. They also add value to a waterfront property and create a pleasing visual. Unlike shorelines, which can be rocky or sandy, marine docks are built to be sturdy and stable. Their design requires specialized knowledge and consideration to ensure they are well-built and will stand up to heavy use and harsh weather conditions.

Choosing the right dock depends on your particular circumstances and budget. Marine construction professionals can help you select the right dock for your needs. They can also help you choose a location that will accommodate your needs and comply with local regulations. They can also recommend the best materials for your dock to ensure it withstands strong winds, turbulent waters, and wear and tear.

Depending on your location and requirements, you may want to consider a fixed or a floating dock. A fixed dock is attached to the seabed through pilings and can withstand heavy loads, massive storms, and tidal currents. However, it can be more costly to build than a floating dock.

A floating dock, on the other hand, is a raft-like structure that floats on top of the water. This type of marine construction is becoming increasingly popular due to its convenience and environmental benefits. It is less expensive to install than a fixed dock and can withstand wind and rough water. It is usually shaped like a rectangle to provide maximum berthing space. Moreover, it can be designed in various shapes to accommodate different types of vessels.

The regular movement of boats to and from the dock can lead to the introduction of pollutants into the water. These can include fuel, paint, and other chemicals that are toxic to marine life. They can also disturb bottom-dwelling organisms and disrupt natural processes. The use of environmentally friendly boat cleaning products and observing no-wake zones can reduce these effects. Some docks can also be designed with grated decking to allow more light to reach photosynthetic species below.

Marine environments are among the most delicate and complex ecosystems on earth. Each component, from the largest whale to the smallest microbe, plays a crucial role in the health of the ecosystem. Marine docks are essential for shipping and recreation, but they should be designed to minimize their impact on the environment.
