Subsea Rust Proofing

Cor-Pro Systems provides high quality subsea rust proofing in Houston, Texas and areas near the Gulf Coast.

One of the major industries that face corrosion problems every day are those in the oil and gas refineries.

Structures, machineries, and equipment submerged beneath the seaboards are at a higher risk of undergoing corrosion process because of its constant exposure to saltwater and humidity.

In recent years, subsea rust proofing Houston gained attention because of the rapid shift of the growing oil and gas industry to sea water technology and energy.

From 1859 to sometime in 1965, oil and gas industries were largely based in “dusty” lands or brown waters and during that time, major structures were in the Middle East Deserts, San Joaquin Valley, Permian Basin, Jungles of Indonesia, and Boardwalks of Southern California, to name but a few.

As the industry started growing at an unprecedented rate, these industries turned to the technology of the sea water where the main building tools included pipeline technology, subsea well systems, and floating rigs.

As expected, the exploration became deeper and deeper into the seas; corrosion became much more difficult to control.

As technology advances, subsea rust proofing becomes essential because steel begins to corrode the day it is cast.

Cor-Pro knows that corrosion is a problem that needs immediate attention because as the corrosion progresses, stability and integrity of subsea equipment deteriorates.

Cor-Pro, together with its NACE-certified and highly competent personnel, ensures that all of their services are superior and complies with international standards.

This follows the company’s goal of identifying the cause of corrosion and the effective ways of eliminating it.

What Is Subsea Roof Proofing Houston?

Subsea rust proofing involves the application of rust-inhibiting measures onto metal surfaces submerged in sea water.

Through the use of anti-rust methods such as surface finishing products as an additional layer of protection, subsea rust proofing stops corrosive agents from reaching the metal surface.  When effectively done, the corrosion process will no longer ensue.

Subsea rust proofing, unlike galvanic treatments, cannot provide permanent coating. Rust proofing has a certain life span that necessitates the need to undergo maintenance periodically to prevent corrosion.

Basic Principles Of Subsea Roof Proofing Houston

Subsea rust proofing is a necessity due to its high likelihood of corrosion.  Subsea equipment are in constant exposure to areas with high salinity and have a corrosivity category and risk of C5-M very high (marine) and have a low-carbon steel thickness loss of >80 to 200 (µm).

To achieve the maximal subsea rust proofing, the following basic principles must be thoroughly applied:

Surface Preparation

This is the first step of treating a steel substrate before applying any coating and is generally accepted as the most important factor that determines the success of the corrosion protection method.

The coating performance depends on its ability to properly adhere to the substrate material.  Initial surface condition varies in the degree of initial rusting.

Though, a good number of preparation methods are available today, the most reliable method for thorough cleaning of rusted surfaces is abrasive blast cleaning.  The standard grade of cleanliness to follow BS EN ISO 8501-1 includes:

  • Sa 1 – light blast cleaning
  • Sa 2 – thorough blast cleaning
  • Sa 2 ½ – very thorough blast cleaning
  • Sa 3 – blast cleaning to visually clean steel

Application of Subsea Rust Proofing

The overall success of subsea rust proofing starts with a well-prepared specification.  Draft of specifications must be by someone with the technical expertise to properly identify the requirement and the corresponding method that is practical and achievable.

Some of the important specifications are:

  • Metal dressing to eliminate projections, sharp edges, and steel contamination
  • Surface preparation method and required standard
  • Allowable interval between surface preparation and priming or metal coating
  • Type of coating to use with its corresponding standards
  • Method of application to use
  • Number of coats required and its relevant coat interval
  • Wet and dry film thickness of each coat
  • Application conditions (shop or in site) including consideration of temperature and humidity
  • Rectification methods for damages, if any

Inspection and Quality Control

To ensure that the subsea rust proofing is optimal, quality control through inspection is mandatory.  Its goal is to countercheck that the application met the specifications.

Inspection of the procedures, processes, and materials required for the subsea rust proofing is vital, as an error in even one method can significantly reduce the maintenance interval.

With Cor-Pro and its dedicated team of corrosion experts and personnel, clients will get nothing but the best subsea rust proofing Houston, as each step is properly monitored.
