TSC Subsea masters the art of deepwater hydrate detection TSC Subsea has announced its latest piece of equipment in acoustic deepwater hydrate detection. The ART ® vPush, provides efficient, cost effective hydrate detection. The ART vPush was developed to meet the specific needs of a major operator. TSC Subsea collaborated with DOF Subsea Norway AS to complete the project for the operator in Angola, West Africa. “In addition to benefiting from the most efficient and fastest hydrate detection and sizing tool on the market, the operator also achieved additional cost savings in terms of dredging requirements,” said Jonathan Bancroft, TSC Subsea global sales director. “The smart design of the ART vPush means that only minimal dredging is required.” Tasked with locating a hydrate in the pipe, the team deployed the ART ® vPush which scanned 12km of 8" 3LPP coated water injection line in just 33 hours at 1,300m. The hydrate plug was found and scanned for exact measurements. Designed and developed by TSC Subsea’s UK team, working closely with the company’s Norwegian acoustic scientists, the ART vPush was designed with speed of inspection as a priority without compromising detection capability and sizing accuracy.

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, which detect if hydrate is present. Typically deployed via ROV manipulator, it can also be fitted directly onto an ROV and has a depth rating of 3,000m. The high-speed data collection minimises ROV and vessel time. Common applications include detection of hydrate in subsea pipelines and wall thickness measurements on subsea pipeline. TSC Subsea www.tscsubsea.com Genebre highlights its pressure reducer valve with piston Valve and accessory company Genebre offers a pressure reducing valve piston, Redux-GE, which sits within its hydrosanitary line. The Redux-GE pressure reducer valve reduces and stabilises fluid pressure based on a pre-set value. The use of this hydraulic device is necessary when fluid pressure of a facility can overcome maximum admissible pressure of other devices that form the facility. The piston reducer is suitable for systems for hydraulic supply, either outside or inside of buildings, where net pressure does not reach values above 25 bar. The structure of the inner piston ensures rigidity, strength and high control accuracy, due to these at compensation. The sealing O-ring assures a low static friction coefficient, ensuring wear resistance and reducing maintenance. The main use is for installation of conditioning, sanitary, irrigation, compressed air distribution against fire and water distribution in buildings. The pressure reducing must be installed respecting the arrow direction engraved on the body. It is necessary to install a filter at the beginning of installation to get a long and good working life. The user needs to consider periodic maintenance of the filters (mesh could need a replacement). Use valves just to let maintenance operations of pressure reducer. The pressure reducer has been pre-set at three bar of outlet pressure. If is necessary to modify it you can: check that the hydraulic circuit is completely full and close all devices; remove the plastic cap from the top that is inserted by pressure; to reduce the outlet pressure, slotted screw must be unthreaded (rotating counter clockwise); to increase the outlet pressure, the slotted screw must be threaded (rotating clockwise). In order to simplify this operation, connect a pressure gauge replacing the plastic lateral cap, which indicates outlet pressure. Genebre www.genebre.es
