ProLINE

What ProLINE does

ProLINE (ПроЛАЙН) is a Ukrainian ship design and engineering bureau established in February 2003 and headquartered in Mykolaiv, a historic shipbuilding center on the Black Sea. The company operates as a pure design house — it does not construct vessels — and instead produces engineering documentation and supervises construction at partner shipyards including Liman Shipyard (Mykolaiv) and Samus Shipbuilding and Shiprepair Plant (Russia). Its portfolio spans the MegaLine series of executive-class megayachts (MegaLine49/50/60/77, up to ~77m), the CatLine series of passenger catamarans (CatLine19 through CatLine82), the MotorLine and SpeedLine motor yacht and superyacht families, SailLine sailing yachts, WorkLine/Pilot technical fleet vessels, and the PowerLine40 light-alloy trimaran. Service scope covers the full project lifecycle: conceptual design, exterior and interior design, project documentation, classification society approval, and construction supervision, supported by 3D CAD/CAM modeling with hydrodynamic and structural analysis.

The bureau's revenue model is project-based professional services, charging design engineering, documentation, and supervision fees tied to individual vessel or series projects — pilot boat tenders priced at EUR 800,000-1,000,000 per vessel and pilot boat tender offers at UAH 76.29M (~EUR 2.38M) per vessel indicate project-level economics where design fees are a percentage of build cost. Reference projects include the 47m ice-class motor yacht Severina (Project OB47) delivered in 2009 for a Russian Arctic-operating private client, and the 48.4m service-traveling motor vessel Baiterek (Project ULBA) delivered in 2009 for Kazakhstan's OJSC Ulbinsky Metallurgical Plant. Customer mix spans government agencies (Ukrainian Seaport Administration), state-owned industrial corporates (Ulba Metallurgical Plant), HNW private buyers, and partner shipyards. The firm is privately held, has never raised external funding, and operates with 11-50 employees under director Leonid Dubrov, supported by Chief Designer Serhiy Miroshnyk and Chief Architect Oleg Prykhodko.

Strategic posture is one of niche specialization (shallow-draft and ice-class megayacht expertise, multi-jurisdiction classification society credentials from Russian Maritime Register, Russian River Register, Kazakhstan Shipping Register, and Register of Shipping of Ukraine) combined with active international repositioning via Hamburg (SMM 2022), Rotterdam (Europort 2023), and domestic Maritime Cluster of Ukraine participation. The client base has historically been concentrated in CIS markets — Russia and Kazakhstan in particular — creating material exposure to the geopolitical disruptions of 2014 and 2022 and driving the firm's recent push toward European clients and tourism/charter segments via the CatLine passenger catamaran line.
