Oceaneering Supports Client with Long-Term FPSO Maintenance Plan

1 The Challenge

The client needed a thorough maintenance management system for its floating production storage and offloading (FPSO) vessel offshore Brazil.

The FPSO is tasked with all primary processing of fluids produced by wells connected to the field’s three platforms and is a critical asset. A locally based team was responsible for developing an adequate solution that aligned the FPSO’s maintenance system with the customer’s existing maintenance philosophy.

2 The Oceaneering Plan

The project’s initial contract ran from 2014 to 2017 and covered 70,000 functional locations.

The scope included:

  • Reviewing technical documentation (P&IDs, maintenance manuals, single line diagrams, and wiring diagrams)
  • Generating a technical hierarchy of the plant functional locations
  • Detailing the mechanical dependencies for mechanical isolation of equipment
  • Implementing a risk-based maintenance strategy following NORSOK Z-008
  • Establishing a criticality classification for all functional locations in the installation
  • Defining preventive maintenance routines and task assignments
  • Outlining maintenance tasks to be performed in each work order
  • Completing a compliance review of maintenance plans according to health, safety and environment national and international standards and regulations (NBRs, NR-10, NR-13, NR-37, NORMAN 01, NORMAN 05, ILO, ASME, SOLAS and DNV).

In addition to delivering the Risk, Reliability, and Maintenance scope, our Fabric Maintenance (FM) and Management team used our proprietary SOLV software to provide surface maintenance solutions for the FPSO.

Oceaneering experts established an approach in line with the client’s FM philosophy that included identifying various administrative units across the FPSO’s 211,286 m² of coated surfaces. This included classifying surface condition based on NACE parameters.

3 Continued Support

Based on the successful delivery of the first three-year contract, the client selected Oceaneering to deliver continuous support for the maintenance management of the installation.

As part of the extension of the contract, the team has been tasked with:

  • Ensuring continuous improvement of maintenance routines, considering methodologies such as Plan Do Check Act (PDCA)
  • Defining and implementing the maintenance strategy (technical hierarchy, criticality assessment, maintenance routines) for new equipment installed on the FPSO
  • Defining and implementing corrective strategies and spare parts allocation using a computerized maintenance management system (CMMS)
  • Delivering the FPSO’s first long-term plan (January 2019 to December 2023) focusing on the evaluation of coated surfaces and describing the systematics for execution of surface maintenance.

Oceaneering participated in the client’s 2020 high activity period (HAP). Our team oversaw the pipe painting scope using SOLV prioritization to identify assets needing the most urgent attention.

We are currently developing the FPSO’s 2023-2026 long-term plan including the condition update of the installation which will include a 39-day offshore campaign that will enable a total surface inspection of 225.023 m².

4 Results

As a result of the initial three-year contract, the client was able to benefit from both a significant reduction in planned maintenance and an impressive return on investment (ROI).

By implementing standardization across operations and modifying maintenance routines, they were able to achieve a 50% reduction in planned maintenance. It is estimated that the savings provided to the operator reached the 10 million USD mark annually. Oceaneering was able to help the customer reshape their maintenance approach using a multidisciplinary team of professionals based in Brazil and Norway.

Continued Client Support

Oceaneering continues to support the client with a local team of mechanical, electric, automation, and material engineers. This ensures that the operator is compliant with national regulations and is able to demonstrate this compliance during audits. By enlisting Oceaneering to provide ongoing maintenance services, the client can:

Maintain the standardization of the maintenance strategy

Verify requirements and remain compliant with standards and regulations

Standardize the work hours attributed to equal activities

Ensure continuous improvement of the maintenance strategy

Safely and strategically reduce planned maintenance

Ensure the quality of documentation used and generated for maintenance activities

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.
