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

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?

SUT+ New Beginnings

5 April 2012 Aberdeen Branch SUT+ Launch Event, Aberdeen, UK

 

Flyer

 

Overview

SUT+ has been created for developing professionals working in the subsea industry in Scotland. It will provide a platform to develop valuable industry knowledge outwith the traditional office environment. SUT+ will provide a programme of technical and social events, arranged by developing professionals for developing professionals, to encourage and extend awareness of the subsea industry.

This launch event, SUT+ New Beginnings, was a social opportunity to learn about SUT+, to meet the people involved, and to meet and network with other developing professionals. The evening included an opportunity to explore the Aberdeen Maritime Museum and to learn about the history of the subsea industry of Aberdeen. The event was open to all but welcomed new entrants to the subsea industry and developing professionals typically in the first 10 years of their career.

The event was primarily a social event, with food and drink provided, but included a number of short presentations:

 

Presentations

Overview

The UK government set a target of generating 15% of energy generation from renewable sources by 2020 and so far the offshore wind turbine industry has taken the lead in developing large scale projects. Tidal and wave energy devices are also seen as key contributors to achieving this target and the industry is currently at a critical stage of transition, from small scale experimental projects to large scale deployment.

 

Presentations

Project Nautilus: Development of a Marine Renewable Test Rig Using Advanced Analysis Tools to Simulate In-field Loading Conditions
Michael Williams, Managing Director, PDL Solutions (Europe) Ltd and Dr Jamie Grimwade, Technology Specialist,  Marine, NAREC

Harnessing marine renewable energy is extremely challenging, and deploying marine renewable devices is costly, time consuming and highly weather dependent. Marine renewable energy developers must be able to prove that their devices work before they are placed in the water and NAREC’s Project Nautilus is a test facility that recreates the loads that the devices will see in service.

A key aspect of the project was to undertake an in-field measurement campaign. PDL Solutions were chosen by NAREC to use this data to develop advanced CFD computer modelling and simulation of the offshore environment, enabling the test facility to simulate the loadings seen in the field. The presentation gave an overview of the development programme.

 

Tidal Demonstration Project
Graeme Mackie, Managing Director, Oceanflow Energy Ltd

Tidal stream turbines are generally seen as the form of marine renewable energy that is closest to market. A number of different turbine technologies are currently undergoing sea trials and this paper gave an overview of the particular issues, technical, environmental and commercial, faced by Oceanflow in demonstrating its grid connected floating, tethered turbine technology.

 

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.
