Marine & Harbour

Description

Galvanic (sacrificial) anodes have historically been used to protect harbor structures such as jetties, lock doors, and sheet piles, as well as steel hulls from ships and ballast tanks against marine corrosion.

Many marine architects still rely on experience and rules of thumb and are not able to guarantee a corrosion-free service life, resulting in high operational and maintenance costs and reduced lifetime expectancy.

Elsyca engineering simulation technology quantifies the corrosion issues and enables the engineer to make informed design decisions. The number and location of the galvanic anodes is determined upfront leaving no margin for error. Even state-of-the-art impressed current CP systems now find in many cases acceptance where simulation shows the substantial cost and performance benefits over galvanic anodes.

Elsyca can help with:

  • optimum selection of the type of CP system (sacrificial vs. impressed current), supported by cost-benefit analyses;
  • support and advice in determining the CP design substantiated by objective simulation results;
  • supply of the required materials, incl. online remote monitoring;
  • inspection of installed system performance, incl. reporting;
  • evaluating CP performance of existing systems by on-site measurements;
  • for military vessels, Elsyca's technology can also quantify the electric and magnetic fields caused by the vessel's CP system (CRM and UEP).
