Kongsberg Maritime has secured a contract from Consórcio Marenova to design and supply integrated systems for four methanol/ethanol-ready handy-size product tankers to be operated by Petrobras Transporte S.A. (Transpetro).
The vessels will be constructed in Brazil under the Consórcio Marenova partnership, which brings together Ecovix in Rio Grande and MacLaren in Niterói. The contract value exceeds NOK 300 million.
Under the agreement, Kongsberg Maritime will provide the complete NVC 615 PT vessel design along with a suite of integrated systems. The scope includes propulsion solutions featuring Promas and controllable pitch propellers, deck machinery, tank gauging systems, and navigation and automation platforms such as K-Bridge, K-Chief, K-Gauge and K-Load.
Each tanker will measure 150.6 metres in length overall, with a breadth of 23.4 metres, a design draught of 8.2 metres and a deadweight of approximately 15,600 dwt. The design is part of Kongsberg Maritime’s NVC family of merchant vessel concepts, which are configured for fuel flexibility, including methanol and ethanol readiness.
Representatives of Consórcio Marenova, Robson Passos and Alexandre Kloh, said:
“This contract with Kongsberg Maritime underscores our shared vision for innovation, sustainability, and industrial strength. By combining Ecovix’s scale and offshore heritage with MacLaren’s long standing naval experience, MareNova is perfectly positioned to deliver these state-of-the-art, future-fuel-ready tankers for Petrobras/Transpetro — while helping drive the renaissance of shipbuilding in Brazil.”
Ronny Pål Kvalsvik, Vice President Sales – Ship Design at Kongsberg Maritime, said:
“This project demonstrates how our NVC design platform and integrated technology can help shipowners meet operational and environmental goals. We are proud to support Transpetro in renewing its fleet with vessels that are ready for the future.”
Per Egil Vedlog, Chief Designer at Kongsberg Maritime, added:
“Our designs reflect decades of development and collaboration with the industry. These tankers will deliver efficiency and flexibility, including methanol/ethanol readiness, to meet changing market demands.”
Kongsberg Maritime has operated in Brazil since 2009, with facilities in Niterói supporting offshore and shipbuilding projects. The company has invested in local infrastructure including a workshop with 100-tonne lifting capacity, automation and control laboratories, and certified training facilities.
