Handling of rig anchors is one of the most demanding and dangerous tasks performed in the marine service industry. Bourbon Offshore Norway AA, Ulstein and handling equipment supplier ODIM have developed a new and safer solution to handling and retrieving anchors, which removes personnel from hazardous areas.
The most hazardous operation takes place when the heavy anchor is weighed and has to be dragged over the stern and onto the deck. Enormous forces are involved and if a cable breaks, serious injuries may easily occur. In the new system, the anchor is brought onto deck in a controlled manner using the hinged stern ramp fitted with twin rollers. When the anchor reaches the top of the ramp, it is tilted forward and parked flush with the deck causing the anchor to come in right over the deck without having to be dragged over the deck edge.
