Abstract
A system for anchoring of a tanker near an offshore production unit (1) which is anchored by means of a number of anchor lines (2, 14) and associated anchors, and from which a tanker (3) in use of the system is supplied with oil or gas. The system comprises a first and a second pair of bottom-anchored buoys (13 resp. 15) located before or behind the production unit (1), as seen in the prevailing weather direction (W), and at a chosen distance from the production unit (1). The buoys (13) of the first pair are located closer to the production unit (1) than the buoys (15) of the second pair, and the buoys (13 resp. 15) of each pair has a chosen mutual distance transversely to said weather direction (W), so that a tanker (3) may be moored in the region between the buoys (13, 15) with the fore-and-aft direction essentially coinciding with said weather direction (W). The system further comprises a collision barrier (22) extending between the buoys (13) of the first buoy pair and being connected thereto, to prevent a collision between the tanker (3) and the production unit (1).
