The four most effective jetty pile protection techniques for offshore construction

The wharf is a critical component of the marine transportation system, serving all maritime travel, trade, and development activities. The wharf structure is exposed to considerable impacts from the corrosive environment, erosion caused by waves, and microorganisms when in operation. The primary priority is investigating and implementing solutions to protect and maintain the wharf structure. This content will present four anti-corrosion solutions for wharves that are highly regarded and provide the most efficient performance nowadays.

Why is jetty pile protection required to prevent corrosion?

Corrosion is a common problem that occurs in all seaside wharf projects. There will undoubtedly be severe consequences if proper and timely wharf coating measures are not implemented. What is the cause of this issue, and how to protect the wharf?

Significant corrosion causes for construction when jetty pile protection is not established 

Because the wharf is positioned on the sea, it is constantly subjected to the direct impact of sea surface water, which progressively causes corrosion. The humid tropical environment, rainfall, and plenty of sunshine and rain in Vietnam also influence the wharf. The temperature is higher in the summer and evaporates quickly, but some rains wet the system. When the weather changes to the rainy season, the humidity rises, increasing the ability of ions to flow through the protective concrete layers, causing the concrete layer to expand as well as cause cracks and speed.

Furthermore, the structure of the concrete layers always has the air passages in the capillaries, which is the component most significantly influenced by external circumstances. When the concrete layer is deeply penetrated and there are no quality jetty pile protection solutions available, the wharf’s corrosion rate increases.

the role of jetty pile protection for construction

Why do we need to set up the jetty pile protection for marine constructions?

Based on the study about the causes of wharf damage in the preceding section, it is critical to research to install jetty pile protection for the wharf to get the higher anti-corrosion ability. Because a well-constructed and well-maintained wharf system to ensure the operation is the first prerequisite for developing the waterway transport system and boosting the country’s economy. Develop and build canal infrastructure to allow seamless and timely transportation of products both at home and abroad. Furthermore, anti-corrosion can extend the service life of the wharf and keep it functioning at a higher frequency for a more extended period.

Furthermore, constructing and installing the suitable jetty pile protection benefits economic development and saves the lives of those who work in maritime wharf areas by reducing tragic accidents to a minimum while working at sea.

4 optimal solutions of jetty pile protection, bring the highest efficiency to marine works

To provide the most appropriate solutions for anti-corrosion wharf construction, it is necessary to study and evaluate carefully the current situation. The four solutions listed below have been considered and can protect the wharf from outside influences.

1. Protect the bridge with an anti-corrosion layer

Anti-corrosion coating is also known as a method of jetty pile wrapping for industrial and oil and gas construction piers, including FBE (Fusion Bonded Epoxy) pier wrapping, 3LPE (Three Layer Polyethylene Coating) pier wrapping, and 3LPP (Three Layer Polypropylene Coating) abutment wrap.

2. Wrap anti-corrosion pillars by the reinforced concrete method

The reinforced concrete cover helps the pipeline resist Archimedes’ thrust stably, which is put on the seabed and protects the channel from mechanical impact. The unique thing about this method of jetty pile protection is the concrete layer is wrapped outside the anti-corrosion or insulation layer without affecting these layers.

3. Wrap the jetty with PU Foam and MLPP

The technology uses PU Foam to improve anti-corrosion and heat insulation for pipes up to 150 degrees Celsius. For MLPP, this technology assumes the function of insulation up to 150 degrees Celsius and achieves 3000 m depth. The combination of PU Foam with MLPP is widely applied to insulation for oil and gas projects at sea.

4. Wrap the wharf with the Bend and Fitting method

Bend and Fitting are used to perform anti-corrosion through “3LPE/3LPP Modified” coating technology. This method increases the heat resistance and good anti-corrosion for the wharf in inclement weather. Moreover, this jetty pile wrapping solution is one of the latest wharf coating technologies implemented through the Series 200 RAM system by highly qualified engineers at VIVABLAST.

The Series 200 RAM system protects jetty structures from corrosion by minimizing highly aggressive wear caused by weathering and microbiological impacts. Moreover, RAM Series 200 prevents corrosion in treated areas when eliminating oxygen and water from the substrate surface, extending the life of buildings up to 27 years. With the specific utilities provided by RAM Series 200, this system is regarded as an excellent option for any project, assisting in protecting the wharf from corrosive and hostile natural agents such as tides and large waves.

4 optimal solutions of jetty pile protection

The process of applying jetty pile protection provided by VIVABLAST’s team

Using wharf covers for projects is very important, so the process of installing jetty pile protection also required detailed steps. It must be performed directly by people with extensive experience, understanding all the characteristics of the project. At VIVABLAST, the process is completed by the following four steps.

  • Step 1: Clean the surface according to SSPC SP2, SSPC SP3 standard, or high-pressure water cleaning technology to remove the damaged structure and organisms
  • Step 2: Apply RAM Underwater Primer to the surface to be protected. If the surface field has heavily corroded holes, it needs to be made by RAM MASTIC
  • Step 3: Wrap the RAM Marine Tape to protect the metal surface by overlapping layers of 55%
  • Step 4: Wrap HDPE sheet (2mm) outside with protection by external forces.

The duration of jetty pile wrapping for VIVABLAST wharf projects is always faster than prior methods such as anti-corrosion spray coating. The efficiency is higher because all steps are performed by certified specialists who are also RAM Series 200 underwater construction talents.

VIVABLAST is now one of the leading services providers in terms of jetty pile protection, based on the knowledge gained from many projects. VIVABLAST is delighted to be the leading wharf construction company in the world.
