Deepwater Mooring Systems Go Deeper
 

With offshore production moving to increasingly deeper waters, the ease and speed of mooring installation has become critical. First Subsea is committed to offering operators and installation contractors mooring systems developed specifically to overcome these deepwater mooring challenges.
 

 Fibre Rope Connector

Working with leading mooring systems company, Offspring International Ltd, First Subsea has jointly developed the next generation of subsea mooring connector – the LankoFirst fibre rope connector. The connector is designed specifically for deepwater projects. Lighter, less complex and, as a result, delivering higher performance than existing systems, LankoFirst will revolutionise the ease with which deepwater fibre mooring lines are connected and deployed offshore. The LankoFirst range includes rope-rope, rope-wire and rope-chain connectors. 
 

Quality Driven
 
As an ISO 9001 registered company, quality management, adherence to international standards and innovation in research and development are an essential part of the motivating force underpinning First Subsea's products and services.
 

World Class Metals Forging Research
 

First Subsea is undertaking the industry's first investigation into mooring systems forging in collaboration with the University of Sheffield's world class Institute for Microstructural and Mechanical Process Engineering (IMMPETUS).
 

The outcome from the First Subsea two-year research project will be a greater understanding of the metals forging process enabling better characterisation of the micro structure of forged metals, with respect to Charpy toughness values and the design and integrity of ball and taper connectors.
 

The project will also equip First Subsea with the ability to characterise and optimise the forged materials used in a ball and taper subsea connector and assist naval architects and engineers when specifying their mooring connection systems.
