September 2018 Project and Technology Update

Thanks to an increased focus on efficiency and a continued commitment to reliability and meaningful data, Welaptega has ridden the wave of change brought on by the recent industry downturn and further solidified its position as the industry leader in in-situ mooring inspections. After a busy Summer 2018 that saw us inspection more than ten mooring systems of permanently-moored floating assets, we wanted to take a moment to let you know what we’ve been up to.

Mooring System Design Considerations

/
A permanently moored Floating Production Unit has a complex mooring system with many constraints. A wide variety of factors must be considered to try to predict the future and account for degradation of the system.

High Standards For the High-Performing Energy Industry

Our work with the pan-industry FPSO (Floating Production, Storage and Offloading) Forum has been focused on mooring integrity and the management of mooring systems. A decade ago, we were a founding member of the FPSO committee that worked toward setting guidelines related to mooring: since then, these guidelines have been adopted by UK Oil and Gas, and is being applied around the world by operators.

Chain Measurement Methods: Pros and Cons

/
Chain wears, corrodes, and degrades. It is designed to deteriorate and intended to have an end of service life. But how do we track this? What methods are out there and what are the pros and cons of each? Understanding the current condition and deterioration rate of the entire mooring system is vital for cost-effective and safe operation of any floating asset - today we look at five different methods for measuring and inspecting one of the most common components of a mooring system, chain.

“Rusticles” Spotted in Deepwater Mooring System in West Africa

/
Welaptega has observed possible “Rusticles” at a depth of approximately 1000m in a mooring system in West Africa. The term “Rusticle” was first coined to describe the unique corrosion formations observed on the wreck of the Titanic after 95 years at the bottom of the Atlantic (Brenda J Little, Jason S Lee, Microbiologically Influenced Corrosion).
