Polish Research on Saturation Diving and its Implementation. Part IV. Modernisation of the AF-2 Diving System

This part of the article presents the process of renovation and technical modernisation undertaken in the first decade of the 20th century in order to repair the system after it was leased to RANA, to secure PETOBALTIC’s investment and, most importantly, to adapt it to the requirements of classification societies and improve the safety and comfort of divers. The work was carried out in several stages and, as a result, the system is operating successfully to the present day. The investor was PETROBALTIC, while the main contractor and author of the modernisation was the Underwater Works Technology Department of the Polish Naval Academy.
