HELSINKI, Finland – Wärtsilä is to supply the design and propulsors/positioning system for two new flexible pipe laying vessels (PLVs) contracted for a long-term charter off Brazil for Petrobras.

Daewoo Shipbuilding & Marine Engineering (DSME) shipyard will build the vessels in South Korea. The owner and operator is a joint venture between Technip and Odebrecht Óleo & Gás (OOG).
