Presentation

The need for intelligent data management for subsea pipeline projects has identified the importance of proper data management practices and the conservation of data integrity throughout the project life cycle. A Geographical Information System (GIS) has been used to store, manage and analyze the digital design, moving away from a paper centric to a more data centric environment.

The early implementation of a GIS system secures a rigid foundation for pipeline data throughout the project data life cycle and integrates data management systems using a widely adopted common platform. The leveraging of data access through third party management systems, such as the industry standard Pipeline Open Data Standard (PODS) model and Subsea Survey Data Model (SSDM), enables a fully functional platform to aid in greater decision support.

The use of GIS functionality and built in analysis tools, enables greater support for Asset Integrity Management (AIM), providing a greater degree of decision support to clients, through means of dynamic visual representation and bolt-on integrity tools. There is an increasing need in the Oil and Gas industry to ensure data is current, accurate and meaningful to ensure the integrity of assets through the full life of field.

Fast Reaction Bespoke Solutions for Subsea Repair
Paul Booth, Engineering Manager, Intervention and Autonomous Systems, Subsea 7

Despite all the pre-planning, engineering and stockpiled hardware, there are occasions where a high quality bespoke solution has to be engineered in the minimal possible time. This presentation looks at a number of bespoke, deep water pipeline repairs carried out over the past 18 months. The deep water application brings added complexity due to the need for ROV installation. The repairs were designed, tested and proceduralised by Subsea7 in conjunction with client/operator requirements, and with input from third parties where additional specialised fabrication or equipment was required.

Subsea Digital Radiography of a Blocked Pipeline
James McNab, Global Technology Manager, Oceaneering International Inspection

Subsea transmission pipelines periodically require internal operations with mechanical “pigs” and “plugs”. These pigs and plugs can become stuck inside the pipeline for various unexpected reasons. It is unusual for operators to track the pig or plug along the full length of the subsea pipeline due to cost and access and the only positioning information usually available is by estimates of the volume of fluid pumped. The difficulty in finding the pig or plug can be compounded if the pipeline is heavy-walled, buried or coated. This paper describes a successful operation for locating a stuck plug and confirming its exact position within a buried 30pipe-in-pipe system. The plug was located using a combination of pressurisation/depressurisation sequences to calculate the approximate distance to the blockage, cleaning pigs with acoustic transponders to refine the location, and finally computed radiography.

Reinstatement of Foinaven Riser-Pullhead Bolted Connection
Neil Stagg, BP Subsea and Pipelines Team, Subsea Projects

Often solutions to unique problems are driven by outside constraints such as availability of specialist vessels, replacement time for main system elements and maximising summer weather opportunities. presentation discusses execution of a concept that evolved through lateral thinking to solve a West of Shetland pipeline-riser bolted connection requirement – and without specialist construction spreads or long lead times. This opens up capabilities for a new approach to subsea bolted connections.

SUT+ Pre-Talk, Pipeline Inspection and Repair
David Kaye, Chief Engineer, Aquamarine Power

Offshore pipelines represent a significant investment and a critical part of an operator’s export infrastructure. A significant amount of effort and expenditure is spent each year in inspecting offshore pipelines, and occasionally, much more effort is spent on repairing damaged pipelines and bringing them back into service. This presentation gives a beginner’s guide to the different pipeline inspection techniques and approaches to pipeline repair.

The SUT held its AGM, annual awards ceremony and members’ dinner at the stunning location of the Trinity House, London (situated overlooking the Tower of London and River Thames) on 5 December 2013. The AGM began at 6.00 pm, followed by the annual SUT awards ceremony honouring those who have made exceptional contributions to underwater technology.

During the awards ceremony, SUT Fellowships were awarded to Andy Barwise and Keith Broughton and Chris Milner. Other Fellowships were awarded to overseas members Earl Doyle in Houston, Trond Olsen in Norway, and Norman O’Rourke and Ian Wilson who are both in Perth.The Society wishes them all many congratulations on their awards.

The Houlder Cup for outstanding contribution to underwater operations was awarded to Mr Mike O’Meara for outstanding contribution to Underwater Operations. Mike O’Meara has a long and successful involvement in the subsea world. He started his career in the Royal Navy and, after training as a clearance diver, was involved in a variety of naval diving operations before leaving the RN in 1975. Mike continued diving for a number of commercial diving companies before joining the newly formed Wharton Williams in 1978 as a diving superintendent. In this capacity he was responsible for the offshore management of diving support vessels and project teams and the implementation of subsea projects in the North Sea, Middle East and Asia. These projects involved a range of commercial diving techniques including air, gas, saturation and lockout submarines. In 1981 he was responsible for the successful salvage of £40 million of gold bullion from the Second World War British cruiser HMS Edinburgh resting in 800 feet water depth in the Barents Sea. After 23 years as an Offshore Manager, in 1991 Mike was tasked with reviewing theh Cullen report and the impending UK Safety Case Regulations following the Piper “A” disaster. The outcome of this work was the formal introduction to the company of risk identification and assessment as a specific planning tool in support of safe operations.

Through the years many changes in company ownership and structure have taken place. These have involved the following leading subsea engineering and construction companies: Wharton Williams, Brown & Root, Rockwater, Subsea Offshore, Halliburton Subsea and DSND into the present day Subsea 7. Mike is Vice-President responsible for Health, Safety, Environmental and Quality Strategy for Subsea 7.

The SUT wishes Mike many congratulations on his award.

The SUT Oceanography Award was awarded to Dr Steve Rintoul in recognition of his contribution to the field of oceanography. Dr Rintoul is a physical oceanographer who works for the CSIRO in Hobart, Tasmania. He has published more than 65 papers in refereed journals and books, with more than 1800 citations. He is on the editorial board of Ocean Dynamics and the Journal of Marine Research. In 2005 Dr Rintoul was awarded the inaugural Georg Wust Medal by the German Society of Marine Research. He was elected to the Australian Academy of Science in 2006 and was made a CSIRO Fellow, CSIRO’s highest recognition for scientific achievement.

In 2007 Dr Rintoul graduated with Honours in Physics from Harvard College, USA, and obtained his Doctorate from the Massachusetts Institute of Technology – Woods Hole Oceanographic Institution Joint Program, USA. He is Co-chair of the International Climate of Antarctic and Southern Ocean (CASO) research programme, Co-chair of the Scientific Committee on Antarctic Research (SCAR) Expert Group on Oceanography, Leader of the Scientific Committee on Antarctic Research (SCAR) Southern Ocean Implementation Panel, and was Acting Chief of CSIRO Marine and Atmospheric Research, May-November 2009. Dr Rintoul’s research has laid the foundation for the growing recognition of the importance of the Southern Ocean in the climate system. For example, he has shown that the Southern Ocean plays a critical role in the global overturning circulation that controls climate. He is internationally recognised as a leading authority on the circulation of the Southern Ocean and how it affects global climate systems. A sign of that recognition is that in 2012 he was awarded the prestigious $100,000 Martha T Muse Award of the US Tinker Foundation, for Science and Policy in Antarctica.

Dr Rintoul’s research has made a profound contribution to our scientific understanding of the Southern Ocean and of Antarctica’s role in the global system. His work has provided new understanding of the structure, dynamics and variability of the Antarctic Circumpolar Current, the largest ocean current on Earth. He has also shown how the Southern Ocean circulation links the shallow and deep layers of the ocean to form a global network of ocean currents that strongly influence climate patterns. His research has provided new insights into the nature, causes and consequences of Southern Ocean change. Dr Rintoul’s leadership has been critical to advancing coordinated international investigation of the Southern Ocean and to promoting long term Southern Ocean observing systems.

SUT was very pleased to award Steve the SUT Oceanography Award for 2013.
