In the unforgiving environment of offshore oil and gas, a single compromised component can shut down operations worth millions. For FPSO vessels processing oil from subsea reservoirs, swivel stacks are this critical link.
When vessel operating costs run €100,000-800,000 per day, component failure isn't just expensive – it's catastrophic.
The nightmare scenario: A swivel stack fails during operation, forcing complete shutdown of an FPSO and costing millions in lost production.
We’ve witnessed the cascading problems that haunt procurement professionals:
Finding engineers who truly understand the complex interplay of high pressure, corrosive fluids, and constant movement in swivel stack design
Sourcing specialized forged components that can withstand sour service conditions while meeting strict industry certifications
Managing multiple suppliers across forging, machining, cladding, and testing – with potential finger-pointing when issues arise
Ensuring every component meets stringent safety and environmental regulations for offshore applications
Balancing thorough quality control against the pressure of installation schedules and vessel availability
When your swivel stack must handle aggressive sour service conditions, standard materials won’t suffice. We ensure proper selection of duplex and super duplex materials with appropriate cladding to prevent catastrophic failure in corrosive environments.
Navigating the complex requirements of maritime certifications across multiple components requires specialized knowledge. We coordinate inspection schedules with certification bodies like Lloyd’s, DNV, ABS, and Bureau Veritas to prevent compliance issues from derailing your timeline.
Swivel stacks must connect perfectly with both subsea equipment and vessel systems. We ensure precise coordination of critical dimensions and connection specifications to prevent costly rework during installation.
Insufficient testing protocols can hide problems until it’s too late. Our comprehensive approach ensures thorough validation at every stage – from material certification to final assembly testing.
Most suppliers have never seen the inside of a forge, let alone coordinated complex swivel stack projects. Our team managed a dedicated division with six specialists focused exclusively on swivel stack projects for leading companies in this specific industry.
Through our network of specialized producers, we deliver comprehensive swivel stack solutions:
High-integrity forged components forming the critical pressure-containing elements
Specialty steels, duplex, and super duplex alloys precisely matched to your operating environment
Expert application of corrosion-resistant overlay materials where standard materials alone won’t suffice
Coordination of heat treatment, machining, and final assembly to ensure perfect integration
Swivel stacks represent one of the most demanding applications in offshore oil and gas:
Having managed these critical projects for decades, we understand the exacting standards required for success.
Maintaining perfect sealing under constant pressure fluctuations
Withstanding aggressive fluids that would rapidly destroy standard materials
Enabling constant movement while maintaining perfect sealing
Components must perform flawlessly for decades in hostile environments
The consequences of component failure extend far beyond replacement costs
