Overview

The offshore wind industry is attracting a significant amount of business and attention, including a number of large scale developments under the Crown Estate Round 3 Offshore wind developments. This meeting looked at some aspects of offshore wind which will be of particular interest to the subsea industry in north-east Scotland. This included an update on latest developments on floating offshore wind turbines, an update of the European Offshore Wind Deployment Centre, to be developed offshore north of Aberdeen, and a short technology bite on condition monitoring technology for wind turbines.

 

Presentations

Floating Wind Turbine Developments

Tim Crome, Sales & Business Development Manager, Technip Norway

Looking at Technip Norway’s experience in floating wind turbine technology, this presentation discussed the transition from Oil and Gas contractor to Offshore Wind contractor with the construction and installation of the world’s first full scale floating offshore wind turbine, Hywind for Statoil. Technip’s alternative design for floating offshore wind, Vertiwind, was also briefly presented.

 

European Offshore Wind Deployment Centre

Jeremy Cresswell, Chairman, Aberdeen Renewable Energy Group

The Aberdeen Bay windfarm project, more correctly known as the European Offshore Wind Deployment Centre, is a ground breaking new facility to be developed off the coast of Aberdeen which will enable the accelerated development of offshore wind power in Scotland, the UK and Europe. The centre will allow offshore wind farm developers and associated supply chain companies to test new designs, prove existing products and receive independent validation and accreditation before commercial deployment. The project has become a strategic project for the EU and which has attracted a 40 million euros grant from Brussels. This presentation will run through the project from its genesis to the present day. The road has been long and far from smooth and we’re not there yet!

The Benefits of Condition Monitoring Applied to Offshore Wind Turbines

Jim Marnoch, Business Director, SKF (UK) Ltd

SKF’s online Condition Monitoring solution (WindCon) is used to verify turbine health and to detect the onset of developing faults on critical components. This reduces cost by targeting maintenance effort at the machines that are exhibiting problems. This increases availability and output from the unit or farm as whole. By analysing the component failure history, and conducting Root Cause Failure Analysis (RCFA), recurring faults can be eliminated by redesign, improving reliability. This presentation looked at the system, operational experience in offshore wind turbines, and how the system may be used for marine renewables.

Overview

Oil and gas fields located in challenging environments have pushed the development of risers technologies and a number of technical challenges need to be evaluated at all stages. Assessing the integrity of subsea risers in operation is now becoming a necessity in order to improve safety, reliability and performance.

 

Presentations

Integrity Management of Flexible Pipe

Patrick Le Stanc, Department Manager, Technip Riser Integrity Management

Events detection and the follow up of service life parameters are presenting a huge interest for operators by allowing them to anticipate any adverse effect on the offshore and subsea facilities in order to maximise the safe service life. If necessary, appropriate action plan can then be scheduled in advance for maintaining the safe operation of the riser system. In order to implement such Integrity Management plans, qualification of monitoring or inspection systems must be anticipated together with the associated interpretation services. Various technologies can be used to support this approach (distributed measurements based on optical fibres, acoustic emission…). The presentation outlined some of the various technologies qualified and under development to support this approach.

 

Integrity Monitoring Systems

Dr Geoff Lyons, Director Systems Structures & Risers, BPP-TECH

This presentation provided an overview of BPP-TECH’s comprehensive experience in the field of integrity management of flexible structures and provide an insight into various new developments in integrity monitoring. In particular the presentation focused upon:

• Moorings (POSMON, CHAMON, OSCAR)
• Tensioned Risers (RMS)
• Flexible Risers (DRIFT)
• Umbilicals (FUMS)
• Pipelines (Fibre Optics)

Overview

Companies in Aberdeen have a long and distinguished record as participants in the global energy market. Our speakers looked ahead to the future of this market, particularly the subsea arena and the implications for both Operators and Contractors.

 

Presentations

Kader Dicko, Senior Analyst, Infield Systems Ltd

Long term market fundamentals of the offshore oil and gas industry are conducive for growth but the deteriorating health of the global economy (Eurozone crisis) will likely play a major role towards this process. If sustained over a longer period, the recent global economic weakening might possibly burst the current bubble surrounding the oil and gas industry, mostly if oil prices considerably weaken below the current US$100/barrel mark and the low business confidence of financial markets spread to the offshore market. The next few months will be crucial to gauge the impact of the global economy status on the offshore industry. The aim of this presentation was to illustrate the current state and medium term outlook of the global subsea and offshore construction market, whilst providing a macro view of different dynamics related to the offshore oil and gas industry.

 

Mike Beveridge, Managing Director, Simmons & Co

Mike presented an update on the capital and financing markets, talking through some major themes which are driving offshore and subsea activity both in the North Sea and Internationally.

 

Working Fairly using Fundamental Principles of Physics – The Synergies between Salvage, Wreck Removal & Decommissioning

 

6 December 2011 One-day conference, London, UK
Organised by the Society for Underwater Technology’s International Salvage & Decommissioning Committee in association with Decom North Sea

 

Flyer 

 

Overview

One of the key objectives of the SUT is the cross-fertilisation and dissemination of ideas, experience and information in underwater technology, ocean science and offshore engineering. To achieve this and as part of the Society’s interdisciplinary programme, the International Salvage & Decommissioning Committee (IS&DC) has joined forces with Decom North Sea to hold a second one-day conference that brings the salvage industry and oil and gas sector together.

Whereas much of the oil and gas sector’s extensive experience to date rests in the design, development, installation and operation of offshore equipment, the decommissioning of end of life cycle assets is an emerging challenge. For the global salvage industry, on the other hand, removing large, frequently damaged and always variable steel structures is part of the everyday portfolio. Having established synergies between wreck removal and decommissioning regarding the physical and operational challenges of removing large man-made objects from the marine environment, the discussion being fostered has become more focused.

This conference homed in on the following:

• Given that each operates under and has understanding of the same principles of physics – why do the salvage industry and oil and gas sector undertake what may be considered to be very similar tasks in such different ways?

• With regard to removal, what is the safest, most environmentally responsible and cost effective way forward – rewinding the construction process or taking a ‘goal-based approach’ in response to an ‘as found’ situation?

• How do we establish a baseline for liability, in order to give a metric for valuing the benefit being conferred by the management, mitigation or removal of man-made objects in the marine environment?

• If new technologies and methods are to be introduced into the activity of decommissioning, how are these to be funded, nurtured and accepted by what is a change adverse oil and gas sector?

Submarine Rescue – The NATO Submarine Rescue System

15 March 2012 London Evening Meeting

Chairman Bob Allwood, Chief Executive, SUT

Overview

Submarining in peace and war is widely acknowledged as one of the most hazardous arms of the services. The first modern submarines came into service in the last decade of the 19th century and many were lost due to poorly understood engineering and operational limitations. Despite the dramatic technological advances in World War 2 and its immediate aftermath, there have been a surprising number of submarine losses since then. Submarines usually sink with the loss of all on board and the nature of submarine operations means that these events have not been in the public eye. However, since the publicity surrounding the sinking of the Russian Submarine Kursk and the aftermath of the event, conducted in the stark glare of the western publicity machine, public interest has been stimulated. The UK is part owner of the NATO Submarine Rescue System and enjoys a peerless reputation as the world leader for its skills both as operator and manufacturer of submarine rescue vehicles. How has this come about? What are the true figures for submarine accidents and losses? How have things improved? What key systems and technologies make up a Submarine Rescue System? This presentation gave a short history of the subject and then approached these questions from the point of view of the acceptance into service of the NSRS and its subsequent exercises. It discussed the problems encountered and their solutions. It also described the likely sequence of events in a rescue attempt and the difficulties of co-ordinating the efforts of many countries that in their normal affairs are hardly on speaking terms and differ widely in their approach to the subject.

The presentation was given by the retired naval Commander Jonathan (Jonty) Powis who has been involved in the subject since 1995. Jonty was in the navy from 1974-2006 during which time he specialised in submarines and navigation. He saw action in the Falklands Conflict as the Navigating Officer of HMS Conqueror and subsequently commanded HM Submarines Unseen, Resolution and Victorious. He was serving in the MoD during the Kursk tragedy and was closely involved in the rescue attempt by the UK. Thereafter he was the Royal Navy’s operational commander of the rescue system and on leaving the service joined the Rolls-Royce team as the Rescue Manager in charge of bringing NSRS into service. He is now working to sell the same system to envious nations that crave the same assurance of reliable rescue for their submarine crews.
