DEVICE AND METHOD FOR STEERING SEISMIC VESSEL |
| 摘要 |
System and method for steering a vessel during a marine acquisition campaign. The method includes obtaining a pre-plot track of a steered point, wherein the steered point is associated with an equipment spread towed by the vessel; calculating an offset between a past position of the vessel and a current position of the steered point; and steering the vessel along a vessel track, wherein the vessel track is calculated by shifting the pre-plot track of the steered point with at least a cross-line component of the offset. |
