What does it take to be a Mooring Inspection Expert?

With minimal training, almost anyone can use a caliper to take a measurement or watch a ROV monitor and claim to have inspected a mooring system. But how can you be sure of the accuracy of these measurements? Was the chain cleaned properly? Was the tool placed correctly and in the appropriate location?

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.

Offshore Safety: A First-level Priority for Third-party Contractors

As third party contractors, Welaptega has a unique and important role to play in supporting offshore safety initiatives. Because we work with such a wide variety of jurisdictions, clients, ROV operators and vessels, we have a unique perspective on safety matters.

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.

Welaptega Data Collection System Upgrade

/
Mooring system integrity verification requires the acquisition and collation of a number of diverse data sets from inspection tools including subsea and in-air systems. We collect a wide variety of data offshore from subsea ROV-based measurement systems, sensor packages and cameras.

“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).

Gaining insights: Diver ops

If you’ve seen the picture of the unidentified bright red deep-water angler fish from an earlier blog you will appreciate that the world of Welaptega is a lot more than just moorings, wellheads and pipelines. It often involves meeting the denizens of the deep in their habitats, far from the realm of National Geographic scuba divers and their hand held cameras.
