Overview
Optimized designs
Baker Hughes offers a wide range of tensioner systems, from conventional pull-up tensioners typically seen on tension leg platforms (TLPs), to long-stroke, in-line ram tensioners traditionally used on spar platforms. We optimize our designs on a project-by-project basis to meet your specific requirements with the most compact, cost-effective solution.
Conventional TLP tensioners
- Compensate for angular offset between vessel and riser
- Compact systems for shorter strokes to save on deck spacing
- Cylinders replaceable during operation
- Configurable cassette frame for lower centralizer during drilling operations
- Large opening through cassette frame for passing tieback connectors
- Composite accumulator bottle for weight savings up to 80% over alternative designs
Ram-style tensioners
- All operations above lower deck
- Full piston area used to develop tension, resulting in higher capacities
- 80% reduction in fluid volume, leaving more volume for gas and resulting in low-stiffness systems
- All components, including accumulators (if needed), can be mounted in a single well bay
- High-pressure seals are all internal. Seals that interface with exposed seal surfaces are for low pressure annulus containment only
- System internally reacts to bending moments if a cylinder loses pressure
- Allow for use of short, untapered tension joint
