Seismic vessels Oceanic Sirius and Oceanic Vega complete tandem drydocking at Damen Shiprepair Amsterdam

Sister-ships Oceanic Sirius and Oceanic Vega have completed a round-the-clock, 10-day maintenance programme at DAMEN Shiprepair Amsterdam (DSAm), the company said in a press release. For eight of those days the two 106-metre vessels were in the yard’s 250-metre drydock no.4 in a tandem arrangement, to maximise the efficient use of resources. The twin SX120 type seismic research vessels are state-of-the-art and owned by CGG Eidesvik Ship Management AS, a joint venture between Eidesvik Offshore and CGG. The builder was Ulstein Verft in Norway.

The primary reason for their visit to DSAm was to have a series of repairs and upgrades as well as their hulls cleaned and repainted. The repairs and upgrades included maintenance on the propeller nozzles of both vessels and, by tenting the area around the propellers, DSAm was able to undertake the work without interrupting or delaying the paintworks. This helped minimise valuable time spent at the yard. The two vessels departed DSAm on the 4th November.

The works were overseen by CGG Eidesvik Ship Management AS, a longstanding DAMEN client, on the basis that, when it comes to safety, quality and working hard around the clock, there is a high degree of consensus between CGG and Damen. Comments from the CGG Eidesvik team included: “The crew and staff members from Oceanic Vega and Oceanic Sirius were pleased with the mutual cooperation and impressed by the quick response on several repair items related to the seismic equipment on board. The safety level and culture were also up to both parties’ expectations and standards.”

Tjeerd Schulting, managing director of DSAm, added: “When riding a tandem, one is steering and one is working the pedals. Only excellent team work will bring you quickly and safely over the finishing line.”
