There was a gentle slope of about 1 m \/ 20 m distance parallel to the closest ridge, which was about 20 to 30 m away (the other ridges were quite far off).\u00a0 The entire deployment operation took around 3 hours from the time that the first loads were delivered by the helicopter, until the last loads were hauled back onboard using the ship\u2019s crane.<\/p>\r\n<p>Photo Credits for this page:
