SUBSEA TECHNOLOGY
OFFSHORE INSPECTION ADVANCES
Digital Edge Subsea, has been busy adapting to the changing environment of off shore inspection. The company has taken on additional developers and work on a number of collaborations with clients to experiment on the best way to collect data remotely. The work is focused on how to send the collected data onshore in the most eff ective way, which allows inspectors to remotely access off shore digital video recorders (DVRs) or even have the DVR onshore with the inspectors. One of the benefi ts of this is that there is a reduced number of operators on the vessel. Meanwhile, other team members

And it retains the logs and project history for review and continuation. The latest build of the DVR software adds the ability to merge existing projects from the same DVR, or projects recorded on multiple DVRs, to create a

form of a multi-screen workstation DVR. Again, it has the same capabilities as the 4U rack-mounted system but with three 17in integrated monitors. The screens fold out from the main unit to create a compact system capable of displaying sonar, ROV topside and DVR displays. ●

DEEPWATER HYDRATE DETECTION TOOL The tool uses the company’s ART
SC Subsea’s latest piece of equipment is a fi rst for acoustic deepwater hydrate detection. The ART vPush provides effi cient,
cost-eff ective hydrate detection at a level that has not been previously available. The ART vPush was designed with speed of inspection as a priority without compromising detection capability and sizing accuracy.
technology on a moving platform to rapidly assess pipeline contents over complete pipe runs. Data is collected in real time and processed with several algorithms to monitor signals from the far end side of the pipeline that detect if hydrate is present. Typically deployed via ROV manipulator, it can also be fi tted directly onto an ROV and has a depth rating of 3,000m. Common
applications include detection of hydrate in subsea pipelines and wall thickness measurements on pipelines. The ART vPush
was developed to meet the specifi c needs of a major

operator. TSC Subsea collaborated with DOF Subsea Norway to complete the project for the operator in Angola, West Africa. Tasked with locating a hydrate in
the pipe, the team deployed the ART vPush, which scanned 12km of 8in 3LPP-coated water injection line in just 33 hours at 1,300m. The hydrate plug was found and scanned for exact measurements. “In addition to benefi ting from the
effi cient and fast hydrate detection and sizing tool, the operator has also achieved additional cost savings in terms of dredging requirements,” says Jonathan Bancroft at TSC Subsea. “The smart design of the ART vPush means that only minimal dredging is required,” he adds. ●
