Diving Deeper into Subsea Data Management

Clarus Subsea Integrity has designed a visually intuitive web portal that can overlay on existing systems or databases. This web portal is aimed to increase the efficiency and effectiveness of integrity management programs and reinvigorate document management.

Over an asset’s lifecycle, project stages change, personnel and contractors change, but data shouldn’t. Yet, valuable time and resources are often spent searching through vast amounts of information due to the complexity in designing, fabricating, installing, and operating a subsea development. This can lead to multiple data sources that can compromise overall quality and control.

Clarus has spent over a decade performing subsea integrity management plans, risk assessments, and engineering analysis. During this time, Clarus has seen many of the above problems cost operators hours of inefficiency and, in some cases, unnecessary action, while further driving up monetary costs in other cases due to delayed reaction time.

In order to combat these challenges, Clarus combined its strong integrity engineering experience with an effective graphical user interface to create ICUE. A web based portal that provides one access point for all of an operator’s subsea integrity management needs. What sets iCUE apart is the fact that it is designed specifically for integrity management by engineers who have completed over 2,000 subsea component risk assessments, 500 anomaly assessments, and a 100 subsea inspection campaigns.

 

iCUE brings key information about an operator’s particular asset to the foreground in a visual and user-friendly format. It allows quick and intuitive paths to data on a graphical user interface that can interface with any existing electronic document system. These paths enable users to obtain all of the integrity management data, on any of their components, within 5 clicks. Operators can obtain meaningful component status overviews and dig deeper into matters such as risk position, visual assessments, KPIs, inspection history, and as-built data.

Laying out data in such a way can demonstrate compliance through auditable performance history and improve operational readiness through visibility of component condition across one or multiple assets. In addition, operator’s integrity data management costs can be reduced by up to 15% with effective data mining.

When You Have Inadequate CP on a TTR

Problem - One of our assets was not getting adequate CP on its production riser. TSA activation was noted during the GVI giving indications that corrosion could become an issue.

Solution - Due to risk-based (non-prescriptive) inspection intervals, CP inspections allowed us to identify inadequate CP trends on the riser. With adequate time, an anode retrofit sled was designed to solve the CP disconnect for remaining service life before it became an issue.

Value Added - Using risked based inspection intervals from our integrity management program, early detection of the CP depletion on the riser was achieve and sufficient time was provided to mitigate through a retrofit sled

New Free Spans and Potential Concerns

Problem - Five unstraked free spans were identified during a Risk Based ROV Inspection exceeding design allowable span lengths. One was not identified during the post-installation span assessment.

Reasons for Concern - Higher stress levels due to free spans exceeding the allowable design length. Increased fatigue damage due to  Vortex Induced Vibrations (VIV) from bottom currents.

Solution - Static ultimate limit state stress check. VIV fatigue analysis (in-line and cross-flow).

Value - The free span assessment confirms flowline integrity and mitigation is not required. Clarus has updated the inspection workpacks to ensure newly identified spans do not progress.

Clarus @ NACE Corrosion Risk Management Conference

Clarus' Vinayak Patil will be presenting at the NACE Corrosion Risk Management Conference in Houston next week. The conference takes place from 23rd - 25th May at the Houston Marriott Westchase. 

Risk Assessment Tool for Corrosion Management – A Boon or Burden? - Vinayak Patil & Dharmik Vadel

Wednesday, 25th May 2016 - 11.35am

Abstract

A risk assessment is a common tool employed by Operators during different stages of an asset’s life cycle, and can be used to varying degrees of depth and detail. With newer oil and gas fields being developed in deeper water and harsher operating conditions corrosion management has become a growing challenge. In case of brown fields, extending life of existing fields by addition of new wells poses its own unique challenge for demonstrating fitness for purpose. A well implemented risk assessment should allow identification, review of operational conditions, and mitigation of credible corrosion degradation mechanisms to prevent any catastrophic failures. However, there are challenges in the application of risk assessments and translation of results into a robust plan for active management and continual improvement of ongoing corrosion management based on results of inspection and monitoring activities.

This paper discusses lessons from a decade of risk assessment application in effective corrosion risk management for offshore oil and gas fields.  Case studies will be presented to demonstrate effective use of risk assessment to support the ability to manage human involvement factor, risk management strategy updates to support changes in operational parameters, and chemicals management with respect to incompatibility of chemicals and role of monitoring. Finally, a few recommendations will be offered with an aim to evaluate and improve existing corrosion risk management practices through effective us of risk assessment as a tool for Operators.

Meet the Team - Meagan Busby

Tell us a bit about yourself!

Hi! I’m Meagan. I grew up in Texas, went to Oklahoma to get my civil engineering degree (OSU, NOT OU), then came back home to Texas! I started working at our parent company, 2H, at the beginning of 2012, right after graduation. I worked on both riser analysis and integrity management there, with the majority of my time on integrity management. Then, in mid-2014, a mysterious meeting was called in which 2H rocked the boat and announced the plan to spin-off a new IM company. I must say I was in shock for a bit there, but I’m so glad I got the privilege to start Clarus with my friends and fellow engineers!

What 3 words describe you best?

Hard-working, detailed-oriented, fun-loving

What do you do at Clarus?

My primary role at Clarus this year has been responsibility for the integrity management program of one of our client’s offshore assets. I also worked on a project to develop riser KPI limits, which is one of my key interests and strengths in IM. In addition to project work, I coordinate the internal training program at Clarus to make sure we are always learning and sharing knowledge.

What’s your favorite thing about working at Clarus?

Meagan on the high ropes

My friends! Which is everyone at this company! I love the camaraderie we have here. It is just as easy to have serious discussions about our project work as it is to poke fun at each other...and poke fun we certainly do!

What’s your most memorable Clarus moment?

Can I really only pick one?! Ok. April Fool’s Day. Our office manager, Jen (who we cannot live without), turned in a fake resignation letter and we all waited in suspense for the two VPs to read it. John Mac almost had a heart attack, though he did a pretty good job at maintaining his composure, and then we all laughed our hearts out. After John read the letter, we pulled the prank all over again with Dharmik, this time with John’s assistance! After we got a good laugh at Dharmik (and some pics) we all proceeded to turn in our own absurdly written resignation letters!

Tell us a bit about life outside work.

I like doing lots of different things outside of work! I’m really up for trying most anything. I like chilling at the pub with friends after work, dancing West Coast Swing, Country, and Salsa, reading, traveling, martial arts…and I ADORE being Aunty Megs to my little sugar-coated niece and nephew!

Fun fact!

My sister and I worked on an organic farm in the Czech Republic for a week last year and had the time of our lives!

What’s the hype about HIPPS? An integrity management perspective.

The predominant topic in the oil and gas industry at the moment is cost reduction; a sharp change from a year ago when most conversations centered around technology development for today’s harsh, deepwater environments. There is one technology, however, that can help meet both of these criteria, and that is subsea HIPPS.

High Integrity Pressure Protection Systems are safety instrumented systems (SIS) and have predominantly been used in the North Sea. They have yet to be implemented in the GoM, but offer significant advantages for operators in the region. The subject was among various technologies discussed during the 7th Annual Teledyne Oil & Gas Technology Focus Day, which Clarus attended on 19th November 2015 at the Westin Memorial City. Here’s an overview of what we learned.

How do HIPPS work?

HIPPS protect downstream equipment from exceeding design pressure limitations, allowing for high pressure wells to tie in to flowlines and risers with lower pressure ratings, ultimately reducing cost. They also allow new, higher pressure wells to tie into existing, lower pressure production systems preventing the need for a new facility altogether. HIPPS monitor upstream pressure by using multiple sensors, and close the barrier valves as soon as an increase in pressure exceeds the preset level. This increase can occur due to a number of different reasons. One example could be a malfunction of the subsea tree choke, which during normal operations provides control of production pressures, resulting in an unplanned opening. Another example could be a hydrate blockage downstream of the HIPPS that causes a rapid surge in pressure upstream.

Why have HIPPS not been used in the GoM?

Actually, a subsea HIPPS is currently being developed for the Julia project in the GoM. However, they do remain a non-conventional production technology and therefore require additional approval from BSEE.  Since regulatory approval depends on historical safety data, which is lacking, the current regulatory requirements can result in a stringent qualification process.

What are the integrity considerations if I am considering a HIPPS?

The reliability of safety valves is a common challenge in the industry, with malfunctions that often result in lost production, repeated troubleshooting and, in some cases, costly intervention operations. Valve redundancy should be carefully considered during design as it can allow you to continue production operations if one valve was to malfunction.

Valve condition monitoring can establish historical safety data and operational KPIs that increase confidence and provide leading indicators before a shut-in.  
The design of the zero burst or fortified zone downstream of your HIPPS, which must be designed to allow for sufficient time for the HIPPS valves to close. The zero burst zone depends on a variety of parameters such as reservoir properties, downstream pressure rating, flow assurance design and field architecture.  Early involvement from your integrity team is crucial in ensuring quick access to reliable data and providing engineering support, especially when designing HIPPS for existing fields where there could be more limitations.

In summary, subsea HIPPS can facilitate newer wells at existing facilities to overcome technical challenges at a lower cost. Nonetheless, early involvement of your integrity team is vital in addressing the added complexity that comes with adding a HIPPS to your field and ensuring the long-term health of your asset.

Special thanks to Robert Hernandez, Sr. Technical Advisor at Granherne, whose presentation “Design and Use of Subsea High Integrity Pressure Protection Systems” at the Teledyne Oil & Gas Technology Focus Day was the motivation for this article.
