What I'm looking for

I’m seeking a Chief Engineer position where I can lead engine-room operations, ensure safe and efficient vessel performance, and apply my STCW certifications and experience with propulsion, machinery, and tanker-related procedures.

I’m a Bulgarian marine engineer focused on safe, reliable operation of ship propulsion and machinery. With a Marine Vessels Eng Diploma, I’ve served in engine-room roles for many years, progressing from 2/E to C/E while working across multiple vessel types.

I bring hands-on expertise in main and auxiliary machinery operation (including electronic and electric propulsion) and strong STCW-aligned safety capability, including advanced fire fighting, survival craft, medical first aid, and bridge/engine teamwork (SSO/SDSD/SSA). I’m also trained for tanker operations (oil/chem), environmental awareness, DP, ARPA, and high-voltage system safe operation and maintenance.
