Bahia Tres’s port and starboard photographs of 27 May 2009 supply the joint venture’s funnel. The flag reference derives from the funnel and company logo.
Bilbao’s Mureloil was a 60/40 joint venture with Naviera Murueta, with both partners managing it and its two vessels. The source also calls it Mureoil and dates formation to 2003. It provided bunkering services; one vessel was chartered to the European Maritime Safety Agency and the other to REPSOL for pollution response.
