The McPherson Buoy was refurbished in preparation for the arrival of the response barge. The buoy refurbishment was done from the anchor-handling and supply boat Endurance. The anchor system was picked up with grapnels and brought up on deck for inspection and repairs. Once inspected and repaired, the system was lowered back into the water, the anchors were stretched to original position and the position of the main buoy was checked.
