Challenge

Exceeding clients’ expectations by providing a cutting-edge INO15 by T.EN™ concept.

Technip Energies rises to the challenge of delivering a winning INO15 by T.EN™ product, meeting clients’ expectations for CAPEX and OPEX.

Our approach involves meticulous cost and weight optimization, coupled with streamlined simplification and standardization, to enable efficient serial production.

Through close collaboration with industry professionals via workshops and exchanges, we acquired valuable knowledge about manufacturing processes, enabling us to customize the product and enhance mass production efficiency. Each design change is thoughtfully evaluated to ensure cost reductions without introducing unforeseen expenses in the value chain.

By selecting Technip Energies as your reliable partner, you will encounter an entirely tailored solution that exceeds expectations and maximizes cost-effectiveness.

Technologies

Joining forces with Inocean team to build the INO15 by T.EN™ concept. 

The INO15 is built on the INO12 by T.EN™ concept (12MW), initially developed by our subsidiary Inocean in 2021. Recognized for its excellence, the concept received Basic Design Approval from DNV and Approval in Principle from BV.

The INO concept represents a three-column semi-submersible foundation meticulously designed to withstand diverse environmental conditions worldwide. This foundation embodies efficiency and resilience with its DNA rooted in lean design principles.

As part of the INO15 by T.EN™ program, we leveraged our in-house simulation tools to thoroughly analyze the dynamics between the floating platform and its integrated turbine. This comprehensive evaluation ensures optimal performance and seamless operation.

Also, T.EN actively engaged in discussions with various fabrication yards to gain insights into their manufacturing processes. This collaborative effort aimed to identify pain points and costly operations, ultimately streamlining the INO15 by T.EN™ design. Implementing these solutions paves the way towards mass production, delivering an efficient and cost-effective solution.

Finding a cost-effective design suitable for mass production.

The INO15 by T.EN™ has been meticulously engineered by T.EN teams as an assembly of several simple blocks, all sharing identical dimensions and making it highly adaptable for efficient serial production. Also, the design of the floater itself has undergone significant simplification, resulting in a more streamlined and optimized structure.

In transitioning from INO12 to INO15, Technip Energies successfully achieved a noteworthy weight reduction of approximately 10% by strategically eliminating diagonal bracings and an upper beam. This breakthrough enhancement translates into substantial cost savings throughout the fabrication process of the floaters.

With its standardized and cost-competitive design, INO15 by T.EN™ stands out as an exceptional solution tailored for FOW industrials. Its streamlined construction mitigates risks and ensures fast implementation, enabling businesses to embrace the ongoing energy transition.

By choosing INO15 by T.EN™ as your preferred option, you can experience a truly customized and state-of-the-art solution that surpasses expectations and maximizes cost efficiency, empowering you to stay at the forefront of the evolving energy landscape.

Results

The INO15 by T.EN™ product has undergone extensive optimization, reaching an exceptional level of maturity equivalent to FEED (Front-End Engineering Design).

It has successfully achieved the expected fatigue life duration, playing a crucial role in reducing risks associated with ongoing FOW projects.

With its industry-leading capabilities, INO15 by T.EN™ became the standard technical choice in pre-FEED evaluations and was selected as the technology for the world’s first FEED of a large commercial wind farm in South Korea. This achievement showcases the trust and confidence placed in INO15 by T.EN™ as the leading solution driving the advancement of FOW technologies.

By embracing INO15 by T.EN™, you gain access to a highly optimized and mature product and position yourself at the forefront of industry advancements.
