The plant mobilised to complete the project included the Ocean Sampler landing barge and Drill Rig 10, a heliportable drill rig. These machines were ideally suited to the site conditions.

The Ocean Sampler is a landing barge with an effective anchoring system which uses a 4 point hydraulic system, ensuring minimal deviation from the hole location. On board is also a DGPS system to further support accurate hole positioning. The overall length of the vessel is 12 meters with a beam of 4.3 meters. For drilling

The overall length of the vessel is 12 meters with a beam of 4.3 meters. For drilling operations, there is an 800mm square moon pool and 39m2 of deck space, ample room for a small drill rig.

Hagstrom’s fleet of marine equipment can be mobilised anywhere in Australia and is serviced from its Canning Vale workshop.

PROJECT SCOPE

  • Two over-water geotechnical boreholes ranging from at least 5 meters into rock or 30 meters in depth. Their location was along the proposed jetty alignment, using PQ/HQ diamond drilling technique.
  • Two over-water geotechnical boreholes extending to depths of 20 meters, along the proposed William Street landing edge wall alignment, using PQ/HQ diamond drilling technique.
  • Two over-water geotechnical boreholes, extending to depths of 20 meters, along the proposed island edge wall alignment, using PQ/HQ diamond drilling technique.
  • SPT tests or U63 push tube in-situ testing to be conducted at 1.5 meter intervals, or when advised by engineers, in soil or low strength rock.

OUTCOMES

Our site investigation schedule was tailored to ensure minimal disruption to the marine activities on the swan river, including ferry activity and private boat traffic. All holes were completed on schedule and without incident.
