Port of Hastings Marine Geotechnical Investigation

Contracted by WorleyParsons Hagstrom Drilling successfully supported a marine geotechnical investigation at the Port of Hastings in Victoria, approximately seventy five kilometres south east of Melbourne, for the Port of Hastings Development Authority (PoHDA).

Commencing late 2013 and operating through until mid 2014, the project entailed the use of two jack up barges – Sealift 1 and Sealift 3, each mounted with UDR 100 Drilling Rigs – to perform the works.  
One of the barges also was configured with a skid based CPT unit which is able to be quickly interchanged with the drill rig to complete cone penetration testing.    

The scope of the project required marine borehole drilling and CPT activities within the Port Area, North Arm, the Western Channel and the Anchorage.

The scope of work completed was 

  • 277m Cone Penetration Tests (CPT) testing at 21 separate locations to depths between 0.54m and 37.04m below seabed. 
  • 2032m drilling at 94 separate borehole locations to depths between 4.4m and 55.0m below seabed, including boreholes in intertidal zones.
In situ shear strength measurements using a down-hole shear vane where also completed.

With significant distances to be covered due to the locations of the boreholes, the use of jet boats for personnel transfers meant minimal impact on the effective working hours as a result of travel to and from the jack up barges. 

Ground information was successfully retrieved and processed and operational logistics was tightly managed so as not to impact port vessel movements.

Hagstrom Drilling take pride in their ability to continually provide a quality service safely.
