Subsea CT Scanning: Fully Understanding Flow Assurance Issues and Validating Pipeline Integrity
As subsea pipelines age over time, the challenges posed to oilfield professionals greatly increase. Pipeline integrity issues such as corrosion, pitting and metal loss defects can arise, which in turn can affect the future operational viability of the line. Similarly, deposition build up such as wax, asphaltene, sand, scale and sludge can occur within the line, potentially leading to full or partial blockages. This in turn can restrict oil production and ultimately defer revenue.
In this webinar, we will discuss how subsea CT scanning can allow oilfield professional to non-intrusively inspect and diagnose a variety of pipeline integrity flaws, as well as identify and characterise a wide range of flow assurance issues. Recent case examples from offshore campaigns in the Gulf of Mexico, North Sea and West Africa, will illustrate how real scan data can be used to inform critical decision making on pipeline life extension as well as remediation – all without stopping or interrupting production.
Tracerco's Jim Bramlett and Rob Hardy will also be available for a live question and answer session after the presentation.

Quick Release, Autonomous Subsea Valve Activator Development
Hydraulic tools specialist, Webtool, has developed an autonomous subsea resettable valve for installation and use with a charged hydraulic fluid store. Easily activated by a steel wire rope line, the valve activation system is designed for applications where autonomous operation is needed in the event of an emergency.
Constructed from stainless steel, the valve activator comprises a ball valve, spring detention cartridge set to the appropriate activation force needed to allow the valve to open, and valve activating lever that also functions as a removable rod arm. Charged with hydraulic fluid, when activated the rod arm rotates through 90 degrees causing the activator’s ball valve to rotate releasing stored hydraulic fluid, when fully open the rod arm is released. The valve activation device can be installed either left or right handed.
The valve activation device is subsea resettable. It features a paddle which is rotated by ROV to the closed position and the system recharged. The rod arm is then pushed back into position by ROV, ready for re-use.
The valve activation system has been successfully deployed on a number of IWOCS emergency disconnection systems. Here the valve is activated by the movement of the Lower Marine Riser Package (LMRP) drifting away from the Blowout Preventer (BOP) on a subsea well. The movement of the LMRP overcomes the resistance of the spring detention cartridge.
Swathe Services Takes Delivery of SBG Ekinox Navsight INS for Customer Demonstrations
Swathe Services has recently added the SBG Ekinox Navsight to their equipment demo pool. After extensive trials on manned and unmanned vessels operating under bridges, in harbours and offshore for Hydrographic applications the performance of the Ekinox Inertial Navigation System (INS) has been exceptional.
Its small compact subsea form factor and weight makes this system light and easy to install with portable sonar systems. It is ideal for shallow water applications and comes at an amazing price compared to competitive INS manufacturers.
James Williams, Managing Director at Swathe explained ‘Since we became the distributor for SBG Systems we have seen as steady increase in sales across all their product ranges selling into land, air, and marine industries. The Navsight solution has been specifically designed for Hydrographic applications and is symbiotic with all Sonars offering ethernet or RS232 connectivity. We now own a number of SBG sensors which we offer out to customers for trial and invite interested parties to contact us.’
