Dual FPSO installation of driven and suction pile mooring systems offshore China

A strategic and creative approach to drive efficiency

We took a strategic and adaptable approach to maximise operational efficiency and minimise offshore exposure. We engineered compact mooring chain storage on barges to save quayside space. We also developed a detailed methodology for handling and subsea deployment of the 500kJ Menck hammer in deepwater. 

Our team optimised pile transfer operations directly from barge to installation vessel and designed customised installation aids to safeguard weather windows and streamline operations. 

By leveraging our global workforce and strong regional networks, we mobilised 23 skilled personnel from nine countries, working alongside local agents to navigate shifting travel and visa requirements without delay. Our partnership-led approach meant integrating closely with the client’s China office to ensure transparent, real-time communication and seamless interfaces with the operator and subcontractors. 

Throughout, we remained focused on collaborative problem-solving, proactive risk management and reliable, consistent delivery in an uncertain and rapidly evolving situation. 

Innovations in action

Technical requirements included tight installation tolerances and large mooring components – 156 mm chains, 256 mm polyester ropes and associated connectors, so we employed key technologies including high-capacity Menck pile-driving hammers, Acteon-engineered installation aids, and offshore-optimised chain bundling methods.  

The result

Through our creative and adaptable approach, one campaign was completed safely within the revised timeline, and the other was achieved ahead of schedule. By delivering across multiple scopes, we simplified the process for the client, mitigated risk and ensured a streamlined and successful project outcome.
