Project Oleg Strashnov

Croonwolter&dros Marine & Offshore was the electrical system integrator and installation contractor for this new build project at IHC Merwede. The Oleg Strashnov is a vessel with high-end technology. Building a vessel of this kind requires technological knowhow and experience in building such a complex vessel. Seaway Heavy Lifting ordered this vessel from IHC Merwede to meet a growing demand for larger offshore projects, and larger vessels with higher capacity for heavy lift operations. Furthermore, numerous operations around the world take place in deeper water, requiring the vessel to be able to transit at higher speeds. The vessel combines excellent quality with properties that allow her to perform demanding offshore operations. Croonwolter&Dros was responsible for the turn-key electrical installation, including electric propulsion. For this innovative heavy lifting vessel of Seaway Heavy Lifting, built at IHC Merwede/Krimpen Shipyard, we developed a diesel-electric propulsion concept, featuring a redundant energy generation and propulsion system.


Croon managed, engineered, integrated, installed and commissioned the
following systems:

  •  Main generators and propulsion motors
  •  New 6.6 kV, 440V and 230V switchboards, emergency switchboards and frequency drives
  •  Dynamic positioning and vessel management
  •  Ballast control system
  •  Cabling for complete electrical installation
