The PelaStar TLP
PelaStar’s tendon system, hydrodynamic design, and mass distribution provide the most stable floating platform on the market to maximize power production and reduce wear and tear on the offshore turbines in deepwater. In addition, PelaStar’s five-arm configuration provides unmatched redundancy—our TLP design can lose an entire tendon or anchor in a storm and stay stable and on station.
PelaStar leverages simplicity to reduce environmental footprint and minimize maintenance costs and complexity. Ready for tomorrow’s 15MW+ turbines, PelaStar streamlines installation with multiple deployment options and modular components that create local content benefits.
- Best-in-Class platform stability:
- Maximizes power production
- Reduces turbine wear and tear
- Improves O&M accessibility
- Lightweight structure reduces CAPEX
- Inherent tendon redundancy unlike any other platform
- Compact footprint maximizes ocean
- Flexible deployment methods
- Regional supply chains, modularized design
Our modular design approach considers all phases of construction and installation. We optimize for marine logistics, port handling, assembly speed, and load out. Multiple deployment methods provide flexibility to developers to alleviate the variety of constraints across projects and geographies.
Many other platforms use complex solutions, like active ballast systems, to compensate for excessive motions. Our philosophy is to minimize the complexity of what is left in the water. Our deep draft central column and minimal motions maximize accessibility and allow for use of existing vessels, equipment, and procedures.
Many floating wind energy platform designs suffer from being anchored with complicated mooring systems spread widely across the seabed. While this approach has been proven in the oil and gas industry for individual platforms, it doesn’t transfer well to utility-scale offshore wind farms. This is because:
- Soft mooring systems result in large turbine motions, degrading power production while increasing wear and tear on the turbines, making it more costly to keep turbines spinning.
- Their large footprints underutilize the seabed lease area, limiting the amount of power a wind farm can generate.
- Their mooring lines are disruptive to fishing and marine mammals; impacts which make it more costly for developers to permit their sites.
The PelaStar tension-leg platform avoids the pitfalls of a more traditional platform designs with vertical tendons that are fit tightly underneath each platform.
- Minimal seabed footprint allows developers to maximize the power density installed in deep-water wind farms.
- Tendons are vertically rigid, which reduces turbine motion, increasing power production and system reliability.
- Simple, robust design provides the most stable floating platform on the market to maximize power production and reduce wear and tear on the turbine.
