After completing an in-depth supplier exercise, involving a desktop assessment, we are very pleased to gain SEQual approval. SEQual is an energy industry portal, that was developed in 2021 to support procurement practices.  Although it’s in its infancy, it is already highly regarded by peers, and is fast becoming the ‘go-to’ for procurement for many large players, providing a quality assurance that suppliers are “ready” for deployment, and saving procurement teams time in accessing various documentation individually.

We are proud to have robust management systems in place, which have been designed using specific principles and frameworks to help us meet and exceed various industry standards. These systems played a role in securing the SEQual registration, as well as the many other certificates and accreditations that we hold, including the following:

  • ISO 9001:2015
  • ISO 14001:2015
  • ISO 45001:2018
  • Achilles FPAL

As many in the industry will know, a huge amount of work, time, and effort is required to obtain each one of these certificates.  The output is a few certificates, but the outcome is far greater – the processes and frameworks that these accreditations help us test and challenge makes for a stronger, and more efficient organisation, which we benefit from, but also our clients benefit too.   It’s important to us, as a team, to keep investing in our systems for the greater good.

Callum Methven and Andrew Mosley, AS Mosley

We are extremely proud to have won an award from the Federation of Small Businesses (FSB) for Business & Product Innovation.

AS Mosley picked up the prestigious award yesterday (8th March) at the Voco Grand Hotel in Glasgow at a glitzy ceremony hosted by the FSB.

The award was given in recognition of developing WellScreen, and AS Mosley's involvement in Digital Twin technology.

WellScreen is a unique screening analysis tool that allows operators in the oil & gas industry to rapidly screen a number of wells at any one time. The tool tests for wellhead fatigue, and highlights wells needing more detailed analysis. The Digital Twin work was in collaboration with University of Strathclyde and Fugro, where we developed a methodology for a Digital Twin for Floating Offshore Wind Turbines.

Attending the event on behalf of AS Mosley, was Callum Methven (pictured), Principal Analysis Engineer, Andrew Mosley (pictured), Director, Eileen Cooper, Marketing Consultant of Limetree, and her husband, Andrew Cooper of Andrew Cooper Golf.

Andrew Mosley, Director at AS Mosley said: “This is fantastic news! We’re delighted to be recognised for the our innovative WellScreen tool, as well as our digital twin work.  WellScreen has taken over five years to get it to where it is today and it’s having a huge impact on our industry and literally saving operators hundreds of thousands of pounds. We are grateful to our clients, for giving us the inspiration and motivation to develop WellScreen. Thanks also goes to our Digital Twin partners and, of course, our staff and dedicated team of expert engineers, who have made this success possible.”

AS Mosley will go on to represent Scotland in the UK Final on 18th May 2023.

Case Study: Subsea Conductor Running in Strong Currents

AS Mosley was recently commissioned to determine safe operating sea state limits for a complex drilling operation, using a 30”conductor, deep (1200m) in the Norwegian Sea.

Undertaking a VIV assessment, strength assessment, and an irregular wave fatigue assessment, allowed us to advise the client to limit the sea state to 4m, which would ensure neither the HWDP nor conductor would exceed their allowable bending stress. This gave them the confidence they needed to proceed, knowing their boundaries and ensuring a safe operation.

Read the full case study here.

What is Vortex Induced Vibration and how can it be identified?

VIV analysis - turbulent flow

Vortex Induced Vibration (VIV) is motion created by the interaction of a fluid flow and a cylindrical profile perpendicular to it.

VIV is an important source of fatigue damage of riser systems and subsea equipment, which are constantly in contact with changing flows of seawater.

When the boundary layer separates from the cylinder and creates an asymmetric vortex, the pressure differences create motion transverse to the flow. As the body moves, the vortex and its pressure change again, feeding back to create further motion. When this happens quickly enough, it becomes vibration of the cylinder.

What is Riser VIV?

The flow of seawater around a subsea riser can create vortices resulting in VIV.  This is important because the vibration can be shed downstream and cause in line, or more damaging cross-flow vibrations, to be created, affecting more equipment.

Where is VIV a problem?

Because of the way VIV is caused, the faster the flow of water, the more likely it is to occur. As a result, deep water locations with a typically high current, such as the Gulf of Mexico or West of Shetland, are more prone to problems with VIV.

What is Riser VIV?

What can be done?

The risk of VIV is generally assessed by as part of a Global Riser Analysis, however, it can be investigated as a separate study.

AS Mosley recommends an initial screening. This will highlight if there is a problem and if so, a full assessment can be carried out along with recommendations to overcome VIV and/or maximise fatigue life.
Shear7 is the industry standard tool for investigating the presence of VIV and the consequential fatigue damage.

A linearised modification of the OrcaFlex or Flexcom global riser model can be used in combination with Shear7 to determine the fatigue life of individual components in the riser system.

In addition to this, OrcaFlex also has a wake oscillator module and this can use the full non-linear OrcaFlex global riser model to investigate VIV if a more detailed analysis is required.

How does analysis of weak wellheads improve fatigue life?

Weak Wellhead Analysis

To ensure success of a subsea well abandonment, understanding the historic damage and loads at the wellhead during operations is obviously vital because it factors into its fatigue life.

The age and design of subsea wellheads is a major factor in their fatigue life. Early ones were based on land wells and very little modification for the subsea marine environment was made. They sometimes included multiple casing heads with no heavy wall extensions and had low capacity HPHs or weak LPH extensions.

Improved

Over the decades since, the design of subsea wellheads has improved beyond comparison. Modern ones have two housings locked together with preload and high-strength heavy wall extensions to enable load transfer.

The inner housing provides pressure containment with provision to support casing, while the outer housing provides the structural support to transfer the axial and bending loads into the soil foundation.

Riser factor

The marine riser equipment used during operations is also a key factor.
Older wells might have originally been drilled with small stacks (i.e. 80Te) and lighter risers. Equally, the modern 6th Generation drilling rigs could have 400Te stacks with heavy wall riser joints – which induce far greater loads.

Soil Strength

AS Mosley presented a paper  - Real time monitoring of subsea well foundation integrity - at the ASME 2020 OMAE Conference that showed soil integrity was critical to the integrity of a well. A number of subsea wells have had to be prematurely abandoned due to excessive soil degradation and therefore a strong understanding of site-specific soil characteristics is key during the well planning stage.

Wellhead analysis

So what can you do to understand the loads, soil support and ultimately fatigue life at the wellhead accurately given its age and design as well as the riser used? An important part of the answer is specialist weak wellhead analysis. A wellhead study using sophisticated global riser analysis techniques can be used to calculate the accumulated historical fatigue damage and then compared to a known safe fatigue limit based on industry standards to estimate the fatigue life for a proposed operation. The data captured is crucial to informing good risk-assessed decision-making.

Benefit

The benefit to the operator is having an accurate estimate for the fatigue life for the wellhead. This in turn allows you to maximise the operability of the well – by knowing how long the wellhead can safely be used with the proposed rig.
