Boskalis & DEME complete Glory Holes for Husky’s White Rose Field

The Dynamic Positioned Fall Pipe Vessel Seahorse has just completed two Glory Holes, at a depth of 120 metres below the water surface, designed for protection of sub-sea wells from iceberg scour in the Labrador Current, 350 km off the Newfoundland coast. This is the first time a contractor has succeeded in excavating glory holes at this northern latitude and at such a depth. An innovative underwater grab and drag system was used for executing this “world first”.
