The company STIV Engineering Ltd. (abreviaion Stain Test Instruments Varna) has been founded in 1990 right after the political changes in Easter Europe by engineers from BULGARIAN SHIP HYDRODINAMICS CENTER. The main activity of the firm is development and implementation of systems with highest level of automation especially in shipbuilding and marine sector.

Main item in the activity list in the beginning is patented full automation system, purposed for mooring and auxiliary winches, regulating the wire rope force intensity as well. This product was successfully implemented on more than 20 vessels built in Varna Shipyard Ltd. (present Bulyard SI Ltd.), for international ship owners. During the years, the activity list is being expanded beyond the margins of marine engineering and included weight control and industry automation in the area of civil engineering.
STIV Engineering Ltd. repeatedly participated in different projects with BSHC (BULGARIAN SHIP HYDRODINAMICS CENTER) such as dyno-stands for Azimuth thruster propellers and different fluid measuring automation systems. Other good relations were created with the Technical University of Varna (Naval Architecture Department), in the area of developing systems for fluid resistance measurement of the vessel’s hull.

Since the middle of 2016, a separate unit has been founded, exclusively for marine projects under the name STIV Marine Division. This unit main activity to develop and produce marine water makers for yachts and small size vessels.

Over the years, the company has established itself as a reliable producer and partner, always strongly following the motto “Give your heart, mind, and soul into even the smallest engineering challenge”.
