PT. Imbema Pacific Indonesia, has over 30 year experience in advising and implementing anti-corrosion measurements for steel jetty piles. 

Corrosion rates in the tropical on-/offshore environment are extremely high. Based on a study by the University of Surabaya, without any protection, the steel wallthickness of an unprotected jetty pile in Indonesia will on average reduce0.02-0.20 mm/year on the sea bottom, 0.05-0.07 mm/year on the top of the pile, but even 1.5-1.75 mm/year in the splash zone. 

Note: This average reduction of the steel wallthickness is an accumulation of corrosion from the outside as well as from the inside of the steel piles.

When investigating quite a lot of jetties all over this country, we find that many jetties are not constructed with corrosion protection in mind. It seems that the owners fully trust their consultants and builders on their word and they should point out the importance of the protection of steel. 

Many previously built jetties have already suffered heavy corrosion damage due to poor workmanship in the field of corrosion protection and lack of professional maintenance. (examples of unprotected jetty piles)


To avoid thickness reduction of the steel wall of the piles we offer the following“all in one” protection systems for new and existing jetty piles:


  1. Splash zone protection Systems for protection of the Splash Zone of the piles
  2. Advanced Cathodic Protection of the piles (e.g. Transformation Rectifier Units–TRU’s and Anodes)
  3. Internal Corrosion protection of the piles (e.g. Denso Inhibitors)
  4. Pile Cap protection of the piles (e.g. Splash zone protection Systems)


As PT. Imbema Pacific Indonesia we recommend the following steps for implementing corrosion management for steel jetty piles:

New Jetties:

1. Team up with Consultants / Owner to design the right system
2. Product selection/production
3. Application

Existing Jetties:

1. Survey and report/budget analysis
2. Product selection/production
3. Technical adjustment existing jetties
4. Application

Survey on existing Jetties

For existing jetty piles we can conduct a survey – at cost - by our experienced engineers to do a comprehensive analysis of the installation at your site and advise you what needs to be done to extend the lifetime of the jetty piles in case the current protection is not adequate. Read more about Survey on Jetties  .....

Preventive Maintenance

Corrosion prevention systems on a Jetty should be inspected on regular basis; e.g.  Splash zone protection Jetty Systems should be inspected every six months on mechanical damage by debris or third parties. If damage is observed repair has to take place in accordance manufacturers instructions.(Examples of preventive maintenance jetty piles Splash zone protection Series)
