Laytime and demurrage: where small owners lose money
A review of where laytime and demurrage claims lose value: notice of readiness, statement of facts, exceptions, calculation errors and time bars.
Founder of Yugen Zetta
Builds software for maritime operations from Mersin. Spent four years in Shanghai and works in Turkish, English and Mandarin.
Ege Baykal is an entrepreneur based in Mersin. He graduated from Tarsus American College in 2019 and lived in Shanghai from 2022 to 2026, studying the Chinese Language Program at Fudan University and then the Business Chinese Language Program at East China Normal University.
Alongside his studies he worked the trade itself: he built supplier contacts for companies at trade fairs and brokered deals, sold copper and aluminium to cable factories in Türkiye, and found manufacturers for foreign investors and e-commerce sellers. He checked and reported on suppliers' reliability and joined pre-shipment checks on the ground.
Today he is building Yugen Zetta: software that lets small and mid-sized owners and operators on voyage charter follow their demurrage from charter party to collection, with fleet, certificate and fuel records in the same place. He runs both the business and the technical side of the product himself.
Music is part of his life too. In high school he sang lead on the TAC Echo'17 stage at Tarsus American College and went on with the band Boş Kemikler, leaving before his move to China. His song "Çık Karşıma" is on Spotify. In Türkiye he has also independently produced concerts with well-known artists.
Demurrage and operations software for owners and operators on voyage charter: AI reads the charter party and the SOF, the operator checks and approves; laytime is calculated to the CP terms, invoices and collections are tracked, and a warning comes before the time bar runs out. Fleet, certificate and fuel records live in the same system. 2026 pilot period, Mersin. As founder he runs both the business and the technical side of the product.
