Oceaneering wins two OTC 2015 Spotlight on New Technology Awards

Houston-based Oceaneering International, Inc. was presented with two Spotlight on New Technology Awards for its Deepwater Pile Dredge (DWPD) and Magna Subsea Inspection System (Magna Scan) products at the 2015 Offshore Technology Conference (OTC).

According to Oceaneering, the awards honor innovative technologies based on broad appeal to the industry, proven capabilities through full-scale application or successful prototype testing, and significant impact with benefits beyond existing technologies.

Oceaneering exhibits on this year’s OTC, with new technological solutions. One of two innovations the company is being awarded for is DWPD which is an electrically-driven system with pumps that provide water jetting and suction to excavate piles at any depth. Another one is Magna Scan, which is a screening inspection tool that assesses the mechanical integrity of assets at a high rate of speed without disrupting production.

DWPD

The company says that that this tool is controlled topside from a dedicated control van. The DWPD is guided into a pile by an ROV, which also operates manual valves to control the water jetting. The jetting provides a 360° pattern to fluidize the soil inside the pile, and then suction pumps remove the soil from the pile. Markings on the dredge are used to ensure proper depth is achieved and that the critical internal features of the pile are successfully cleared of debris.

With the DWPD, equipment and infrastructures can be properly installed. The advanced tool helps support subsea assets by removing soil and transporting it in a controlled manner to a discharge site.

Magna Scan

Prior to the development of the Magna Scan, conventional UT methods have been the primary inspection technique optimized by the industry for online assets, the company says.

It is further explained that the Magna Scan only requires clean surface access from the top portion of subsea assets. The advanced system is ROV-deployable, inspects volumetrically 360° around the pipe, and provides real-time data of the wall condition within a single deployment.

Providing the way the Magna Scan works, the company says it identifies localized defects and general wall loss by optimizing ultrasonic techniques including lamb and shear horizontal guided wave capabilities. Oceaneering also claims that by combining automated scanner the Sea Turtle with proprietary ultrasonic sensors, the system is capable of detecting internal and external damage mechanism including corrosion, isolated pitting, cracking and other potential anomalies. According to the company, this system assists in preventing any disasters that may be caused by damage mechanisms in subsea piping resulting in the release of product into the environment.
