An Innovative Subsea Lifting Development System Using a Unique Pumpable Deepwater Buoyancy Liquid Gel
Serena Arif, Subsea Business Director, Aubin Ltd

The requirement of low density materials with high compressive strength to provide subsea lifting down to 3000m has traditionally resulted in the use of syntactic foam; currently being disrupted by the introduction of a precise means of placing, recovering & moving structures on the seabed by pumping a low density incompressible liquid gel from one holding receptacle to a controlling receptacle, enabling fine control/trim/ballast.

Narec Site Tour and Renewable Energy Lecture

18 September 2013 North of England Evening Meeting

Report

Flyer

 

The North of England Branch of the Society for Underwater Technology visited The National Renewable Energy Centre at Blyth in Northumberland.

Narec operates world‐leading open access and independent translational research, development and testing facilities for offshore wind, wave, tidal and electrical network technologies, and work with industry to increase device reliability, reduce product costs and accelerate the development and deployment of offshore renewable energy technologies in the UK.

The evening was chaired by Ignacio Marti, Chief Technology Officer of Narec. Ignacio also described Narec’s testing facilities and the R&D projects that Narec are delivering across the supply chain and how Narec are helping to reduce the cost, and accelerate the commercialisation, of offshore renewable energy technologies.

Cable Risk Assessment – A Quantitative Approach
Peter Allan, Managing Director, Geomarine

All offshore generating equipment relies on seabed cables to transfer power to shore. All revenue is therefore reliant on the integrity of these cables making them an essential part of the system.

Previously, the concept of a burial protetion index has been used to indicate the security of a cable.
However the approach was qualitative, and did not provide a reliable model for assessing the probability of damage occurring. New developments such as AIS systems for monitoring shipping traffic now allow a quantitative model to be developed. This can then be used to develop a reliable financial model for the cable, with a realistic basis for whole life maintenance costs.

The presentation described the methodology Geomarine have developed for cable risk assessment and provide example case studies of its application.

Floating Vertical Axis Wind Turbines – Current and Future Developments
Chris Golightly, Independent Geotechnical and Engineering Geology Consultant

The July 2013 Deep Water Wind report from EWEA states that offshore floating wind will be competitive in water depths of over 40 m against current fixed structures such as monopiles, jackets, tripods, gravity base structures, multi and single suction caissons. However, innovative new designs will be required in order to take advantage of the huge resources available in the Atlantic, Mediterranean and deeper parts of the North Sea. Early work in France (NENUPHAR) and Japan (SKWID) as well as considerable research in the USA indicates that taut tension anchored floating Vertical Axis Wind Turbines [VAWT] will play a major role in the future. This presentation discussed these alternatives.

3-5 September 2013 Aberdeen, UK

Chairman: Dr Bob Allwood – Chief Executive, Society for Underwater Technology

 

Conference Sessions

 

Overview

Session 1: Emerging Technologies in the Subsea Sector

With the demand for oil and gas set to steadily increase, the ability to produce safely, efficiently and economically in increasingly deeper water depths and hostile geographical locations will depend on the development and utilisation of new technologies. However, it is well known that this industry (rightly) adopts a very conservative approach to new ideas.
This session identified the potential subsea prospects in the coming years, examining some of the new technologies close to being adopted and looked at the processes that need to be followed if these aims of safe, efficient and economic production are to be met.

Overview

Session 2: West African Developments

West Africa has rapidly become one of the world’s most important regions for the production of oil and gas. It is estimated that it holds around 8% of the world’s reserves. With political turmoil in some of the recognised major producing areas of the world in recent years, it is not surprising that major importing countries have focused their attention on West Africa. With the participation of multinational companies being encouraged, the general high quality (high API) of oil in place and relatively low commercial costs, it is not surprising that this region is very attractive to foreign investment that has resulted in the rapid increases in productivity seen in recent years. This session provided an update of activity in this region.

Report

Jonathon Doyle, Senior Engineer, Atkins
At the end of design life, the operators of subsea equipment and pipelines face a choice between decommissioning or justifying the extension of the life of their assets. Factors such as commodity price, enhanced recovery techniques, and the economic viability of new infrastructure all contribute to the decision. In recent years Atkins has worked on a number of subsea and pipeline life extension projects, ranging from major infrastructure to small subsea tiebacks. Jonathon will discuss the motivations we have seen for life extension, the techniques that we have employed, and some of the challenges that we and our clients have experienced.

Life in the Old Dogs Yet—An Evaluations of the North Sea’s Remaining Petroleum Resources
Prof Jon Gluyas, Head of Department, Dong/Ikon Chair in Geoenergy Carbon Capture & Storage, Department of Earth Sciences, Durham University

In mid-1975 the Argyll Field became the first UK North Sea oilfield to produce oil. Seventeen years later in 1992 the then operator deemed life was over for this modest sized field and the expectation was that many more fields would follow suit. Indeed by the turn of the millennium it was anticipated that many of the large fields in the North Sea would be abandoned, the expected 30-35% yield factor of oil would have been met. Yet today in 2013 very few fields have been abandoned and many continue to produce oil economical albeit with reduced rate. Professor Gluyas will discuss some of the more likely enhanced oil recovery methods – those which modify the properties of the connate water or the viscosity of the oil and will also examine reservoir contributions to OPEX reduction by examining the value in co-produced fluids.

The sky is not the limit but there are good technical reasons to believe tertiary recovery could add 10% to the ultimate yield of oil in the UK.
