Subsea Controls Integrity

14 May 2014 Aberdeen Evening Meeting

Chairman: Richard Ficken, Subsea and Pipelines Manager, Total E&P

SUT+ Pre-talk
Richard Ficken, Subsea and Pipelines Manager, Total E&P UK

The opening presentation will provide a very simple overview of the subsea control systems basics, main failure types and some distinct aspects of the subsea controls market. Resulting integrity and management strategies will also be discussed.

Obsolescence Theory and Integrity Implications
Andy Gower, Subsea Controls Engineer, Total E&P UK

The paper provides a recap of the relevant obsolescence definitions and theory applied to the integrity of subsea control systems. Implications are explored including consideration of the resulting mitigation strategies.

Subsea Control Failures and Remediation—Operational Experience
Rik Ingram, Deputy Manager, Subsea Operations and Equipment Group, Wood Group Kenny

Four case studies are presented representing some of the common operational failures experienced in subsea control systems. The four case studies are an example of IR dropping consistently, HPU control fluid contamination, potential DHSV failure and HPU loss of fluid. Each case study discusses diagnostics, potential operational implications and the proposed solutions.

TECHBITE
Jeremy Edwards, Operations Manager, Viper Subsea Ltd

The Techbite slot is for new and innovative technologies to be presented. Viper Subsea Ltd will present the recent advances in LIMs remediation equipment.

Condition Monitoring
David Hicks, Senior Product Manager, GE Oil and & Gas UK Ltd

When a subsea problem occurs, it has not been, historically, straightforward to diagnose or to address efficient maintenance. This can mean that unplanned interventions are required, with the serious cost impacts that these may entail. Due to these factors, delivering robust subsea facility health information is of increasing interest in the industry. Health data may be effectively acquired and analyzed, allowing operators to plan effective maintenance regimes and minimize downtime due to equipment failure. The types of instrumentation involved in system integrity monitoring also allow flow assurance measures to be implemented in order to mitigate disrupting factors such as hydrate or wax formation. Further, increasing levels of encrypted data may be transferred to operator or equipment vendor remote facilities, allowing additional expertise to be involved in objective decision-making on operational issues as they occur. A key challenge is to ensure that relevant data is intelligently processed and presented in order to facilitate such decision–making.

 

 

Subsea Pipeline Design and Installation –
Reducing the Risks

13 May 2014 London Lunch & Learn Meeting

Chair: Brian Jones, London Offshore Consultants

Speaker: Trevor Jee, Managing Director, Jee Ltd

This session will be presented by Trevor Jee, Managing Director of Jee Ltd, and will provide attendees with an insight into the subsea oil and gas industry. Attendees will gain an appreciation of the primary steps involved in pipeline design, construction and installation. The associated risks and appropriate mitigations will also be discussed, drawing on real-life case study examples to highlight what could potentially go wrong and lessons learnt from previous projects.

Trevor Jee’s distinguished career in the oil and gas industry has spanned 35 years, with the majority of that spent at the helm of his own company. As the managing director of Jee Ltd, which is now in its 26th year of business, Trevor has led the way in completing successful projects and implemented global training courses that have set the standard for industry best practice.

Trevor holds an MA and Honours degree in Engineering Science from Oxford University. He started Jee in 1988 following nearly a decade with BP and has developed a broad range of experience of pipelines from managing engineering projects for major operators such as BP, Subsea 7, ExxonMobil and Statoil.

In addition, he has contributed to numerous industry codes and standards such as PD8010 for onshore and offshore pipelines and ISO21369 on testing mechanical connectors for use in pipelines.
