ROVAUSTRALIA-based Neptune Marine Services has added two work-class remotely operated vehicles to its UK-based fleet, bringing its total number of ROVs to 15.

The two fully refurbished 150 HP TMRV systems are both rated to 3,000 metres, come with a tether management system and provide Neptune with the capability to perform a broad range of ROV tasks including pipeline surveys, inspection repair and maintenance operations, drill support and heavy duty construction operations.

The acquisition, which Neptune said was for a seven figure sum, would allow the company to offer clients a more flexible and cost effective solution, Neptune UK ROV and survey general manager Scott Freeland said.

“Neptune currently undertakes a wide range of intervention and subsea survey activities on a global basis in the oil & gas and renewable sectors and these latest acquisitions will play an integral role in allowing the company to support our current and future clients and their operations.”

The first vehicle became available for works at the end of February, with the second vehicle scheduled for delivery mid-March.

The news came as Neptune’s Australia-based subsea stabilisation division announced it had completed the structural grouting of the Riser Support Structure (RSS) under contract to a subsidiary of McDermott for the INPEX-operated Ichthys LNG Project.

McDermott is the appointed main contractor for the subsea umbilicals, risers and flowlines engineering, procurement, construction and installation portion of the project.

A team of seven Neptune personnel, including two engineers, performed 24 hour operations to complete the works safely and on schedule – with works completed by January 2015.

Following completion of the RSS scope of work, Neptune completed the initial campaign of subsea grouting of the scour protection systems (SPS).

The SPS were designed, fabricated and installed to the subsea structures prior to installation.
