Cutting of Risers
Service Description
We deliver precision cutting services for FPSO risers, enabling safe disconnection and removal during decommissioning, or urgent intervention work. Our cutting operations are executed by certified divers using mechanical or hydraulic tools, supported by tailored lift and recovery procedures when required.
We help FPSOs manage riser removal scopes efficiently, safely, and with full control over the asset’s structural and environmental exposure.

Subsea Riser Cutting for FPSO Operations
Whether due to structural damage, replacement requirements, or end-of-field planning, FPSO operators often require the clean removal of riser systems below the waterline. SubseaPartner provides cutting and disconnection services for flexible risers, steel risers, and hybrid configurations.
We support:
- Riser cutting at fairlead, hang-off, or midline location
- Separation of damaged risers during emergency response
- Disconnection scopes during turret reconfigurations
- Decommissioning support for suspended or redundant risers
- Preparation for plug and abandonment (P&A) of connected wells
Our cutting tools and methods include:
- Cold cutting shears for flexible risers
- Hydraulic guillotine saws for steel pipe
- Abrasive diamond wire systems for precise subsea cuts
- Control over cutting angle, debris containment, and post-cut inspection
These operations are integrated with:
- Riser recovery or abandonment programs
- Flotation or ballast-assisted rigging plans
- Safety controls for splash zone and structural interface work
SubseaPartner ensures that cutting operations are planned in accordance with classification, environmental, and project-specific safety protocols. If your FPSO campaign involves riser removal, changeout, or clean-cut isolation, our subsea cutting services deliver safe, repeatable results offshore.
Operational Scenario
Real Results: Cutting of FPSO Riser Remnants to Allow Dry Docking.
Challenge
Flexible risers under FPSO turret cut by ROVat -30m required cutting flush with DBSC’s.
Solution
SubseaPartner executed diver-led cold cuts using custom built diamond wire cutting saw.
Outcome
All remnants successfully cut & recovered to flat top barge, FPSO dry docked without issue.
