The project involved many technical, logistic, workplace on water and HSE (Health, Safety, Environmental) challenges. The work has to be done from the waterside utilizing a barge. All the equipment and materials had to be transported over water to the designated area. The traditional technology of water-jetting and impact hammers is not allowed in this vibration-sensitive area due to safety regulations for the local refinery.
The installation method with a Variable Moment Vibro Hammer was the appropriate solution. With the technical support of Dieseko Group engineers, Pertamina trusted their local contractor P.T. Bima Karya Kaloka, to carry out this renovation job.
