X-bow seismic vessel joins WesternGeco fleet
The first seismic vessel with an Ulstein X-bow, the WG Columbus, recently delivered to WesternGeco, has completed her maiden Atlantic crossing. Built at the Barreras shipyard in Vigo, Spain, the Ulstein SX 124 design vessel will dock in Miami in a few days for adjustments in the seismic track steering in the DP system with the seismic equipment deployed at sea. This is part of the preliminary testing prior to her first assignment in the Gulf of Mexico.
There was positive feedback from the trial run earlier this year. "The shipowner was indeed happy that the ship could maintain a speed of 15 knots in 55-knot winds and 3- to 4-meter waves," says Ulstein Design project manager Mikal Warholm. "Mick Richardson from WesternGeco reported that the ship sailed smoothly and steadily through rough weather."
In December 2007 WesternGeco's parent, Schlumberger, purchased Eastern Echo, which then had four seismic vessels of Ulstein Design under construction at the Barreras yard in Spain, and an additional two ULSTEIN SX124 vessels at Drydocks World in Dubai. The WG Columbus was completed first, to be followed by the others later this year. WesternGeco has its head office in Houston, Texas.
