Hallin Launches its Own Remote Operated Vehicle

2008.02.07 - Technology

Hallin Marine announces it has designed, built, tested and successfully demonstrated its own Remote Operated Vehicle (ROV).
The C-ROV (pronounced Sea Rov), was designed and built by Hallin staff at the Company’s Singapore manufacturing facility and fulfilled a brief to create a technically advanced, low cost 100HP, free-swimming, work class machine.
The C-ROV will operate in depths to 1,000mtr and can be fitted with a range of specialist sensors and tooling to carry out wellhead intervention, drill support and survey work.
It will complement Hallin’s existing fleet of heavier duty, tethered, deeper operating construction and work class ROVs and the company’s range of smaller, inspection class ROVs.
The Company has an immediate in-house operational requirement for all initial production units, in line with existing demand for its ROV services. In the future the Company may consider building C-ROVs for other subsea operators.
The AIM quoted provider of subsea solutions to the oil and gas industry has expanded the size of its Singapore manufacturing facility by 50 per cent to cope with the sustained high level of demand for its in-house designed and built saturation diving systems and the C-ROVs.
To facilitate this expansion, the Company has signed a lease on a factory unit adjacent to its existing building at the Loyang Offshore Supply Centre.
The Hallin board has decided it is appropriate, given the current and projected sales values and scale of the Company’s manufacturing, to form a standalone Manufacturing Division.
This is the Company’s third division (the others are the operations East Division and West Division) and, like the other divisions, it is to be headed by its own managing director, Andrew Threlfall.
