Innovative Corrosion Control for the World’s Offshore Infrastructure

Founded in 1986, Deepwater is a full-service offshore corrosion control company, supplying the oil and gas industry with expertise in cathodic protection and asset integrity management. Using our own proprietary product designs, Deepwater has always focused on innovative methods and new products to improve lagging industry standards. The result is a much more reliable and cost-effective approach to corrosion prevention offshore. From zinc and aluminium sacrificial anodes to full-engineered impressed current cathodic protection systems, Deepwater provides design, manufacturing, consulting, delivery, and installation supervision to all of the world’s main market areas. A




A. Neptune Spar, Gulf of Mexico In August / September 2009, Deepwater retrofitted the cathodic protection system on the Neptune Spar. The original cathodic protection system on the hull was approximately 300 sacrificial aluminum anodes. At the request of the operator, DCSI designed, supplied and commissioned a retrofit impressed current CP system (ICCP). B. “Arnold” and “Oyster” Fields, Gulf of Mexico In February 2008, Deepwater performed anode retrofits on 2 subsea development systems in 73 hours. These deep water installations, located in water depths ranging from 775 to 1,750 feet. The installation was accomplished utilizing a DP-equipped ROV Support Vessel equipped with two ROVs. The assets protected were: 4 flowlines, 4 well trees, 2 flowline manifolds, and 2 umbilical termination units. C. Forties Field Flowlines, North Sea In October 2007, Deepwater performed the first phase of a complete cathodic protection retrofit for Apache’s Forties field, in the North Sea. Assets to be protected by “phase 1” consisted of the in-field pipelines, linking the 4 original Forties platforms (Alpha, Bravo, Charlie, and Delta). A detailed design was performed in order to calculate the optimum number of sleds and the correct sled spacing, and suitable subsea locations were selected for equipment installation to minimize the installation time. D. Offshore Wind Turbines, Irish Sea In June 2005, Deepwater supplied and supervised the installation of seven (7) Vaulted Seawater Envelope (VSE) anode arrays on wind turbine monopiles in the Irish Sea. Each monopile was retrofitted with one VSE and one transformer rectifier. These monopiles are located in 8 m -10 m water depths. The VSE anode system is the only shallow water cathodic protection system of its kind, minimizing the risk of snagging by fishing activities while maintaining a uniform circuit resistance when the system silts over.

Cathodic Protection Design & Engineering

An introduction Deepwater designs and manufactures cathodic protection systems for offshore and marine assets, specializing in the development of innovative retrofit technology for aging assets in need of life extension.

Cathodic protection design services and corrosion consulting from NACE certified experts. Deepwater Corrosion Services began in 1986 as an offshore corrosion inspection company. Since then, our focus has shifted toward designing and manufacturing solutions to the many corrosion problems we discovered offshore, namely failing cathodic protection systems. We have a large staff of NACE certified corrosion engineers, experienced in all aspects of cathodic protection science. By encouraging them over the years to put their efforts into innovative new methods and products, we have a built suite of proven, reliable cathodic protection system designs that have served to protect new and aging infrastructure assets all over the world. By perfecting a few innovative designs, Deepwater is bringing the science of cathodic protection up to speed with the developments in today’s cutting edge energy market.

Over the last 20 years, our cathodic protection systems have been designed to provide a more efficient and affordable alternative to traditionally installed anode systems. While conventional sacrificial anode systems are still the most efficient solution for certain new projects, aging infrastructure and new types of offshore assets (FPSO’s, deep water fields) require the cathodic protection designer to be open to new ideas and methodologies in order to streamline installation and reduce overall project costs. Looking Forward: Life extension for aging assets In 2009, Deepwater retrofitted sacrificial and impressed current cathodic protection on 124 structures in the Gulf of Mexico alone. As the rest of the world’s subsea pipelines, FPSO’s, wind turbines and traditional jacket structures (platforms) become mature, operators must consider the smartest and safest way to keep them protected. Recognizing installation as the most significant cost in an anode replacement project, our products and installation methods reduce the time required to retrofit CP to an existing asset significantly, while providing a lengthy new life of up to 25 additional years.

A Wealth of Experience Though we specialize in retrofitting aging cathodic protection on most types of offshore assets, we also provide a full range of corrosion consulting services for unique cathodic protection problems. We have an extensive resume of failure analysis and diagnostic consulting services, as well as traditional cathodic protection design and evaluation. Over the years we have seen and corrected almost every type of cathodic protection design error or other corrosion mishap there is. If your corrosion problem is more specific or more baffling, we can find the solution.

Polatrak® Monitoring Systems

Cathodic Protection Probes

Deepwater manufactures an entire range of instruments and readouts designed to allow operators to monitor all aspects of corrosion control on any type of asset. Permanent monitoring systems provide a constant, reliable stream of information about an asset’s corrosion control systems. Traditional corrosion surveys are costly and time-consuming to organize, especially when problems occur outside of the normal inspection cycle. With permanent monitoring, asset integrity managers can feel confident about the cathodic protection systems they have in place and about knowing when an anode system must be replaced. A monitoring system comprises two main components:

Deepwater’s Polatrak brand of corrosion testing probes are recognized as the industry standard for accuracy and dependability in the offshore market. Unlike other cathodic protection testing equipment, all Polatrak probes are designed with dual elements, for real-time calibration and increased accuracy.

Fixed Instruments The DR-2 (dual reference electrode) and V-String (zinc electrode) are our standard electrodes for collecting cathodic protection potentials. For a more comprehensive portrait of the CP system, the DR-2 CD provides both potential readings and current density data, allowing the operator to monitor polarization.

CP Gun (for Divers) The CP Gun is the most user-friendly, diver-held cathodic protection probe on the market, outperforming all other bathycorrometer type devices in accuracy and convenience. Longer battery life and ultra-bright LED displays make the CP Gun the most user-friendly diver-held CP probe available.

Readouts Monitoring instruments are usually hard wired to the surface, where any number of different monitoring panels or data recorders can interpret the data. Deepwater has also developed a subsea readout call the SunStation, which requires no outside power source or interface with the surface. This new technology has allowed monitoring to go into deepwater fields and other previously inaccessible areas.

Deep C Meter Readout The Deep C Meter is the premier ROV cathodic protection survey system for use in deep water, designed for rugged service on a work-class ROV. With 316 SS pressure housing and a fully articulating mount, this system can go to work out-of-the-box on cathodic protection survey.

ROV II Probe The ROV II is the world’s best selling general purpose tip contact cathodic protection probe. It easily interfaces with the ROV, but can also be held by divers, serving as either a tip-contact or proximity-style probe.

Risk Based Corrosion Inspection Services

An introduction Corrosion at pipe supports is one of the leading causes of process piping failures. Beam supports and pipe saddles create crevices, where water is trapped and held in constant contact with the pipe surface. Once corrosion is initiated, it then undercuts the paint film, moving away from the crevice and causing rapid wall loss. If these conditions are not addressed, entire sections of pipe can fail to the point that they require replacement. Deepwater developed the I-Rod brand of pipe supports specifically to combat crevice corrosion and ensure a long, safe life for pipelines by eliminating the crevice between the pipe and the support. I-Rod brand pipe supports have been in service since 1989, when the first new structure specified I-Rod by name.

For over 20 years, Deepwater has been leading the way in offshore corrosion inspection. From our very first topside corrosion inspection job over 20 years ago, Deepwater has always maintained that reliable inspection data is the crucial first step toward an effective corrosion control program.

Nu-Bolt Designed by corrosion engineers, the Nu-Bolt assembly combines the half round I-Rod support with a modified pipe U-Bolt (pictured). Nu-Bolts provide reliable, long term service for process piping in the severe operating environments associated with offshore oil and gas production and coastal process facilities. I-Clip I-Clip is an individual pipe support clip installed on the inside diameter of a pipe saddle. The clips themselves are mechanically held in place, allowing them to be retrofitted easily along existing pipe runs. New Grinnell and cradle-style supports can also be easily fitted with I-Clip systems.

Topside Level 1 Inspection Deepwater began doing platform inspections in 1988, the very year the MMS required “Level 1” was born. Since then we have focused on continually improving the value of our inspection services. The basic format for most Level 1 surveys in the Gulf of Mexico was developed by Deepwater, now often imitated but seldom improved. Our multi-point, risk-based inspection procedure and reporting ensure that operators spend inspection dollars wisely, keeping costs low and staff safety a top priority. Subsea Level 2,3 Inspection Deepwater has been heavily involved in Level II – IV surveys for over 15 years, and we have rigorously maintained our certifications as training and inspection requirements have changed. Deepwater is a pioneer of “true” underwater cathodic protection surveys, developing a number of survey techniques to give a true representation of conditions, rather than a report that simply satisfies a code. In-Service Inspection Plans Deepwater coauthored the ISIP for one of the first floating production facilities in the Gulf of Mexico. The ISIP originated as a means to reconcile the US Coast Guard requirement to conduct a dry docking at two year intervals; it has expanded to satisfy the USCG and MMS requirements.
