NEPTUNE Marine Services’ subsea stabilisation division has snagged its second subcontract for Ichthys liquefied natural gas project, off the coast of Darwin.
The contract was handed out by McDermott Australia, which is the main contractor for the subsea umbilicals, risers and flowlines engineering, procurement, construction and installation portion of the project.
The value of the contract wasn’t disclosed.
The initial subcontract included the design and fabrication of specialist scour protection systems and the secondary scope entails the grouting of the riser support structure (RSS) and grouting of the SPS.
Neptune’s in-house engineering team in Perth provided the engineering design of the scour protection systems and the fabrication is managed at Neptune’s facilities in Asia.
Delivery of the scour protection systems is expected to start in the third quarter of 2014, with third-party installation of the offshore structures to begin the following quarter.
Neptune will perform the associated grouting once the systems are fully installed.
Neptune said the scopes followed its delivery of concrete mattresses for the Ichthys project earlier this year by Neptune’s Subsea Stabilisation division.
“Following the completion of multiple scopes of work for another key client by other Neptune divisions, our Geomatics and ROV businesses also performed the pre-lay survey and array installation for McDermott in 2014,” Neptune chief executive Robin King said.
