Our office is comprised of five high-skilled employees, naval architects, marine engineers, surveyors and electrical engineer, many of whom with worldwide professional experience??????.  We undertake projects of any scale, from .


Situated in the heart of Piraeus, the centre of naval activity of Greece, Petychaki  Technical Company has been long involved greatly in designing and building innovative vessel prototypes. Our company’s history dates back to 1985 when our “one-man design studio” was first founded; the same studio that has now grown and risen into prominence in the fields of naval architecture and marine engineering. Novel approaches and solutions, passion for detail-oriented craftsmanship and ceaseless pursuit of new challenges, are all traits that distinguish our projects ranging from past to present and from the present to the promising future.


Nikolaos Petychakis was the man who dreamt of creating a new type of vessel for his country, Greece. Inspired by the greek archipelagoes, he quickly grasped the necessity of new and original ideas; an inspiration that made him design the double-ended ferry prototype. The first double-ended ferry, named “Salaminia”, was constructed in 1998 in a Greek shipyard. Our office provided all designs, did all the research and followed up all works closely because of the vessel’s original and innovative design. The construction of “Salaminia” was followed by another 28 double-ended ferries, all of which were built under our supervision. However, Petychaki Technical Office would provide many more services, not limited to the above activities. Our company is in full alignment with the market’s needs and transitions and having as our priority our customers’ satisfaction, we have also conducted studies and created numerous designs for Ro-Ro passenger vessels, cruise vessels, sail cruise vessels, sail catamarans, catamaran ferries, tug boats, fishing boats and tankers.
