Oceaneering Uses CRWOCS for Tree Installation in North Sea Successful operations kick-off larger RWOCS campaign

1 Project Overview

In early 2020, Oceaneering was contracted to supply and operate its Compact ROV Workover Control System (CRWOCS) to support the installation of vertical Xmas trees (XT) for a major E&P company.

Due to the project site in the North Sea, the CRWOCS was an ideal solution to address space limitations while maintaining exceptional functionality and reliability. While the customer had various options to address their workover and completions needs, they ultimately chose Oceaneering based on our long track record in completing these work scopes in the North Sea. Since 2012, Oceaneering has successfully supported XT operations in the region, completing 26 mobilizations of the same technology to complete over 54 XT installation and plugging and abandonment projects.

2 Our Solution

The CRWOCS boasts high functionality while being nimble enough to work within the confines of the subsea infrastructure.

The customer also required a system capable of being deployed from both a rig and a vessel as both methods were scheduled to be used during the installation operations. With reduced footprint, expedited mobilization, and the ability to reduce personnel on board, the CRWOCS provided the ideal solution.

3 Excecution Plan

In order to support the successful installation of the first vertical tree, the Oceaneering team completed configuration of the system and system integration testing in Bergen, Norway, one week before offshore operations commenced.

The CRWOCS was deployed from Oceaneering’s facility in Stavanger, Norway. The system was installed onto an Oceaneering Magnum® work class ROV and successfully supported the installation activities over the course of less than two days. While the ROV was piloted by rig-based personnel, all technical support was delivered from onshore locations. Additionally, high bandwidth data communications enabled the customer to view real-time operations from their location.

4 Results

The CRWOCS delivered flexibility, adaptiveness, and responsiveness for the client’s operations.

The Oceaneering team was able to effectively and efficiently configure the skid to meet the project requirements and execute the project work scope in advance of the targeted completion date.

Providing the customer with real-time project monitoring added an extra level of reassurance of the status of operations while using the CRWOCS. This successful campaign marks the kick-off of a project work scope that is scheduled to stretch into mid-2021.

Company page Since our founding in the early 1960s, Oceaneering has expanded and grown globally to service several industries such as the offshore energy industry, defense, entertainment, material handling, aerospace, science, and renewable energy industries. In 1964, Mike Hughes and Johnny Johnson formed a Gulf of Mexico diving company called World Wide Divers. The company grew in response to increasing demand for their services and in 1969 merged with two other diving companies to form Oceaneering International, Inc. To solve the toughest challenges, we do things differently, creatively, and smarter. As your trusted partner, our unmatched experience and truly innovative portfolio of technologies and solutions give us the flexibility to adapt and evolve, regardless of market conditions. Our mission is to solve the unsolvable. We thrive by creating industry-changing technically creative solutions for the most complex operational challenges under water, on land, and in space. Our five core values establish a common culture and demonstrate what is most important for us as a company. Since the beginning, the company has transformed from a small regional diving company into a global provider of engineered products and services. Today, we develop products and services for use throughout the lifecycle of an offshore oilfield, from drilling to decommissioning. We operate the world's premier fleet of work class ROVs. Additionally, we are a leader in offshore oilfield maintenance services, umbilicals, subsea hardware, and tooling. We also serve the aerospace, defense, and theme park industries. Underpinning everything we do, safety is not only the foundation of our core values, but it is vital to our unmatched performance record and company culture. The industries we serve are as diverse as they are complex. Whether we are engineering deepwater umbilicals or developing robotics for aerospace applications, the safety and health of our employees, vendors, and customers is an integral part of our day-to-day business. If we are working, then our responsibility is to be working safely. Since our inception in 1964, we have placed a high value on employee safety—from diving services and subsea inspection to vessel-based installation operations. We have and will continue to evolve not only our health, safety, and environmental (HSE) processes, but those of the industries in which we work. Although we have been fatality-free since 1999, our HSE journey goes beyond statistics. As our portfolio of services has grown, we have continued to prioritize and advance our approach to HSE.
