What You Need To Know About Underwater Construction

by Erik Evans

If you're interested in working in the underwater construction industry or are curious about the field, there are a few things you should know. Here is everything you need to know about underwater construction.

What is underwater construction?

Underwater construction is any type of construction that takes place underwater. This can include anything from building bridges and piers to constructing dams and levees. In order to do this type of work, in addition to construction experience, you need to be a certified diver and have experience working in difficult and dangerous conditions.

Underwater construction is a niche field. There aren't many companies that specialize in this type of work.

What types of projects does underwater construction involve?

Underwater construction projects can involve a variety of different things, including:

  • Building dams, bridges, and other structures
  • Repairing existing underwater structures
  • Inspecting and maintaining underwater pipelines
  • Constructing offshore platforms and rigs
  • Building artificial reefs

Additionally, underwater construction workers may also be involved in salvage operations or environmental cleanup efforts.

What challenges does underwater construction present?

Each project will come with its own unique set of challenges that need to be overcome in order to complete the work successfully. For example, when constructing a new dam, the construction team will need to account for the immense pressure that the water will exert on the structure. This can be a very difficult task, and if not done correctly, can lead to catastrophic failures. Similarly, when repairing an underwater pipeline, the construction team will need to make sure that the repairs are properly sealed so that water does not leak through and cause further damage.

In addition to the challenges posed by the work itself, the construction diving team also has to contend with the difficult and dangerous working conditions. They must wear heavy diving gear in order to be able to breathe underwater, and this gear can make it difficult to move around and perform the necessary construction tasks. Additionally, the workers are constantly at risk of getting hurt or even killed if something goes wrong while they are working underwater.

Because of the challenges involved, it is important that construction teams work closely with experienced and qualified diving contractors in order to ensure that the work is completed safely and correctly.

What are some common underwater construction techniques?

There are a variety of different techniques that can be used for underwater construction, depending on the project. Some common techniques include:

  • Dredging. This is a technique that is often used to clear debris or sediment from the construction site.
  • Piling. This is a technique that is used to drive piles into the seafloor in order to provide support for the structure being built.
  • Welding. This is a technique that is used to join together metal components. It is often used to construct offshore rigs and platforms.
  • Concreting. This is a technique that is used to pour concrete into forms in order to create the desired structure.

Additionally, there are a number of specialized techniques that may be used for specific projects. For example, when constructing an artificial reef, the construction diving team may use a technique called bio-rock accretion to encourage the growth of coral on the reef.

Underwater construction is challenging and dangerous but can be completed safely and successfully with the help of professional construction diving contractors.
