Oceaneering Supports Australian P&A Campaign with Bespoke Tooling and Hardware Bespoke solutions designed and delivered within compressed timeframe

1 Project Overview

In early 2021, Oceaneering assisted with the permanent plug and abandonment (P&A) of two wells located approximately 120 miles offshore Northwest Australia. The field consisted of two-off deviated gas wells drilled at a water depth of approximately 135 m.

As part of the P&A operations, the existing horizontal X-mas tree (HXT) control interfaces needed to be removed via a recovery tool and were replaced with a subsea control interface skid to provide hydraulic control of HXT lines and valves using production and installation hydraulic flying leads (HFLs). The HXTs and associated subsea hardware were covered extensively in marine growth requiring the engineering and manufacture of custom control skids, marine growth acid cleaning shrouds, flying leads, and marine growth removal tools.

2 Our Solution

Project scheduling was particularly challenging due to a compressed design-to-delivery timeline. Our Australian-based team met the extensive design requirements by leveraging Oceaneering’s global design engineering pool to ensure around-the-clock progress across time zones.

As required, the project had operational support and increased its resource capacity by using Oceaneering’s design hubs in Stavanger, Norway; Houston, Texas; Morgan City, Louisiana; Aberdeen, Scotland; Rio de Janeiro, Brazil; and Chandigarh, India.

The complex design requirements were navigated through early engagement with the client, generation of design concepts, and production of detailed engineering drawings, and documentation to capture client feedback.

The team was required to complete the procurement, fabrication and machining, assembly and testing of the required equipment within a short timeframe. The team executed the project with detailed project and resource planning, exemplar supply chain management, and the provision of 24-hour operational support.

3 Excecution Plan

The full duration of the project from request for quotation (RFQ) to the offshore campaign spanned from May 2020 to March 2021.

The purchase order for the project was issued in September 2020, initiating the engineering and design phase (September-December 2020). Procurement and assembly activities were completed from November 2020 through January 2021 and the hardware underwent testing in January and February. The equipment was mobilized to site in February 2021 and the offshore campaign was executed in March 2021.

4 Results

By leveraging its extensive experience in the design and build of subsea structures and subsea control systems, the Oceaneering team successfully and safely completed and delivered all services and equipment to the client within the agreed timeframe.

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.
