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?

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.

Welaptega: First Class Mooring Inspectors

When it comes to mooring inspections of offshore floating production installations, Welaptega is at the top of its class. This is the result of more than 20 years of experience performing inspections and assessments in every corner of the globe as well as a relentless commitment to continuous improvement of its knowledge base, execution, and R&D. Many of the inspections performed by Welaptega are carried out to meet the requirements of various classifications societies such as Lloyd's Register and DNV-GL.

Risk Assessment in All Walks of Life

When assessing risk of an operation, the UK Oil and Gas considers both the consequences of failure and the probability of failure. Each plays a crucial role in determining the attention that should be paid in preventative action. Consequence of failure is the outcome of a possible hazard (What happens if…) where the probability considers how likely it is that something will go awry (How likely is this to happen?).

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.

Testing SAMIR Update

SAMIR (Semi-Autonomous Mooring Inspection Robot) testing is continuing with excellent results so far; we are getting the system ready for the offshore trial scheduled later this year.

Mooring Integrity Management: What to Monitor, How to Inspect, When to Analyze?

Mooring systems are designed to last for long periods of time (generally 10 to 30 years) in extremely challenging environments. Between tropical cyclones, accelerated corrosion, and constant fatigue loads...

Severe Weather Hits North Sea Production Units

A pair of severe winter storms battered UK and Norwegian North Sea assets over the last week, with winds up to 160kmh and waves of 10-12m. One storm, Nina, is considered be the strongest storm to hit Norway in 20 years.

Mooring System Reliability in the North Sea

A study performed by DNV GL has shed light on how strength capacity of Mobile Offshore Drilling Unit (MODU) mooring systems relates to overall mooring system reliability; in short, it doesn’t. Comparing failure rates from installations operating on the UK Continental Shelf (UKCS) to those operating on the Norwegian Continental Shelf (NCS), there is little change in the rate of single-line and multi-line failure despite increased strength requirements for NCS units.

What is mooring failure?

The primary objective of a mooring system is to maintain vessel position to protect the risers and prevent collision with nearby infrastructure. So at what point is a mooring system considered to have failed: single line failure, two line failure, or at the point of collision or riser failure?
