Seismic research ship Oceanic Sirius

Seismic research vessel with a towing force of 140t during seismic operations. Ideally suited to acquisition of large 3D, 4D or high-resolution projects, utilizing a streamer configuration of up 16 streamers separated by 100 m or more. The 20 streamer winches are each capable of spooling 9 kilometres of streamers. Classifications: DnV1A1, E0, NAUT-OSV(A), OPP-F, CleanDesign, ICE-C, COMF-V(3)C(3), COMF-C(3), HELDK-SH, RP Ulstein Verft delivered the vessel on 3 October 2011 to Oceanic Seismic Vessels - a company owned by Eidesvik Offshore and the seismic operator CGG Veritas. She is a sister vessel to Oceanic Vega, delivered in 2010. On the occasion of the sister vessel's naming, Jan Fredrik Meling, CEO at Eidesvik Offshore, stated: "She meets strict environmental standards. Equipped with state-of-the-art technology, the ship reduces harmful atmospheric emissions and prevents oil discharge through the double hull construction. We are very satisfied with the X-BOW® vessel Viking Poseidon previously delivered by Ulstein. The ship operates smoothly with minimal vibrations and movements. This grants optimal vessel comfort, which is very important for the working conditions of our seafarers." Carrying an ICE-C classification, the Oceanic Sirius can operate in cold waters. The vessel is designed to stay permanently at sea, with five-year docking intervals, and complies with the redundant propulsion notation from DNV. There are enough engines and generator sets to conduct maintenance at sea, and refuelling is carried out by dedicated support vessels.
