Engineering and experience are at the heart of all our subsea designs. Our engineering specialists support projects throughout the energy lifecycle evolution from concept development to project sanction and beyond.
Our teams have the skills to define and deliver the right field architecture solutions to enhance value in the field development process, bringing together the right disciplines to define and optimise the subsea system.
With our broad experience and ability to collaborate effectively within multidiscipline teams we are able to find the right field architecture solutions that are optimised at the system and sub-system level.

Our flowlines team is highly experienced in the design and analysis of rigid pipelines including reeled, S-lay and J-Lay installation modes for corrosion coated, wet insulated, internally lined and Pipe-in-Pipe systems.
In addition, we perform installation and in-place analysis assessments of flexible flowlines. Our fit-for-purpose and optimised flowline designs are developed by the team keeping in mind the operational requirements, in-place design, pipe mills, delivery schedules and installation vessel requirements, identifying and reducing project execution risks whilst meeting design and operational requirements.
We have a full range of riser designs inhouse and one of the broadest portfolios of delivered solutions in the industry.

Our pipeline products form an integral component of the field development plan and can enable optimisations in topside design as well as subsea.
Extensive portfolio of high performance and cost-effective flowline systems to enable optimal field architecture. We focus on enabling the reliable and economic flow of well streams from the reservoir to the receiving facility over increasing distances without costly host modifications.
We have one of the largest portfolios of deepwater riser systems in the world. Subsea 7 provides deepwater and ultra-deepwater riser technology best suited to the field characteristics including extreme water depths, harsh environments, host constraints or hydrocarbon composition.

Subsea 7 provide fully-integrated solutions, engineering services and enabling technologies that protect the integrity and optimise the performance of subsea infrastructure throughout life of field.
Our field-proven track record spans over 40 years and through our combined expertise and ingenuity, we are at the forefront of innovation and change in order to provide sustainable operations and greater efficiencies to clients.
We offer a unique range of skills, services, products, assets and enabling technologies to deliver tangible benefits to our clients.

Subsea 7 is a global leader in offshore energy construction projects, operating in all water depths and conditions. Subsea 7 installation experts have delivered many world firsts, reducing the cost of field developments, improving predictability and enabling the world’s most complex projects.
Subsea 7 covers engineering, procurement, construction and installation (EPCI) of subsea umbilicals, risers and flowlines (SURF) and associated subsea architecture, providing safe, on-schedule and cost-efficient installations by world-class vessels and teams.

Subsea 7’s pipelay fleet is capable of delivering solutions in both shallow and ultra-deepwater using the most technically and cost-effective installation methods from reel-lay to S-lay, J-lay and Towed Pipeline Bundles.
Our repair and maintenance capability is led by highly experienced project teams. From planned routine interventions to emergency pipeline repair systems, we provide the products and services to ensure production assurance.
We have an established and proven track record in the delivery of custom large-scale Emergency Pipeline Repair Solutions for repairing 32”, 42” and 44” pipelines.
For over 3 decades we have ensured that our clients’ infrastructure is repaired and back on-line with minimal downtime and at optimised cost.

Umbilical services; hydraulic, electrical and fibre optic testing

Since the 1970’s, our engineers have been at the forefront of technology development, shaping the global subsea industry, taking it deeper and farther. Today, we’re making it more economical. By designing integrated subsea systems with cost reduction in mind, we have streamlined engineering, manufacturing, installation, life of field services and project execution for a better subsea future.

Subsea processing systems have been increasingly valued by operators to enhance field economics by maximizing recovery, increasing production and reducing costs. We are the forerunner in delivering subsea processing solutions having successfully installed systems in a broad range of brownfield and greenfield applications worldwide, which has enabled our clients to overcome the challenges of accessing difficult reserves.

Strong portfolio
Our broad portfolio extends into separation, pumping and compression to deliver complete solutions to maximize production and lower costs per barrel. Our processing equipment performs in water depths up to 2,500 meters (8,200 feet), in temperatures to 350F and pressures to 15,000 psi.
