Hydratight, a joint integrity specialist, and Connector Subsea Solutions, a deepwater pipeline specialists, have partnered to design the subsea Riser Cleaning and Inspection Tool (RCIT).
“The RCIT can be deployed either near to or onto the riser where it will traverse into position,” said James Rowley, Hydratight’s global subsea market development manager. “The cleaning heads will then remove all excessive sea growth as the RCIT travels along the riser or pipeline. There is no need for ROV or diver intervention, which reduces risk, and the operation can be performed with the support of the most basic of vessels.
“As the riser is cleaned, a concurrent inspection can be performed. Such an inspection clearly provides assurance of continued system integrity. Should damage be discovered, the size, depth, location and severity can be recorded. Once the cleaning and inspection is complete, should there be requirements for repair or maintenance then we can support this.”
The first field units have operated successfully offshore Brazil within the last 12 months.
Rowley will present his paper on remote riser cleaning and inspection at the Subsea Expo 2016 on 4 February as part of the integrity management conference session.
