First published October 2022.
Since the first publication of these Guidance Notes, in 2014, there has been a significant increase in the scale and number of offshore renewable energy projects. While projects in northwest Europe have led the way, renewable energy projects are now being proposed and progressed in many parts of the world, including significant projects in North America, Asia and Australia. Wind turbines (and thus their foundations) have been getting larger.
The Guidance Notes are designed to be generic in nature, and to be applicable to a wide range of offshore renewable schemes, worldwide. Although, they are neither intended to be a standard nor a specification, they are technically robust and represent the state of the industry at the time of writing. Whilst the techniques and processes referred to are common and widely used in the marine environment, each project will have its own specific requirements.

Guidance Notes for the Application of Geophysical and Geotechnical Techniques for Reducing Tophole Risks in the Drilling of Offshore Wells

The Offshore Site Investigation and Geotechnics (OSIG) Group of the SUT is pleased to announce its Guidance Notes for the Application of Geophysical and Geotechnical Techniques for Reducing Tophole Risks in the Drilling of Offshore Wells.
The offshore oil and gas industry spends around 1$60bn per year on oil and gas wells. Investment on this scale comes with risks, and although the offshore industry leads the way in industrial HSSE standards, it is estimated that around 10% of this expenditure, or $6bn, can be attributed to ground related issues such as stuck pipe, lost circulation, wellbore instability and shallow water flows. On top of this are environmental costs of the oil spills that can result from loss of well control, and most importantly the human costs in terms of injuries and loss of life resulting from some of the worst incidents. Given the appropriate data, analysis, engineering and application these risks and costs can be foreseen, mitigated and ultimately reduced.
Tophole integrity and risk reduction depends on understanding the soils and rocks throughout this section of the well. The primary sources of information are complementary geophysical (remote sensing) and geotechnical (intrusive) methods. In the top few tens of metres reliable geotechnical data may be available, but deeper than this information is often limited to what can be inferred from logging while drilling and is far from precise. Geophysical data are normally available throughout the tophole section, although their resolution will always decrease with depth, and their value is limited without proper correlation to soils data.
In this document the risks and problems within and around the well are described. Information and advice in the use and application of geotechnical and geophysical site investigation techniques for the planning of offshore wells are provided. Finally, a systematic approach to assessing and mitigating top-hole geo-risks is suggested.
The document is aimed at:
Geoscientists and engineers involved in data collection and analysis;

Volume Three: The Law Governing AUV Operations – Questions and Answers
By ED Brown and NJJ Gaskell
ISBN 0 906940 40 0, Softbound, 2001
Order Reference C24, Price £50*, Members £45*
This report was commissioned to provide the engineers and programme administrators working on the Natural Environment Research Council’s Autosub projects with an easily accessible digest on the law relating to autonomous underwater vehicles. The questions have mostly come from the AUV community and reflect the concerns that it has about operating these novel vehicles in accordance with national and international law.
In providing answers to questions put to them by AUV practitioners, it has been the objective of the authors of this publication to give concise, practical guidance on the law governing problems which may arise in the day–to–day management and operation of AUVs.

Order Reference C23, Price £80.00*, Members £72*
This report was commissioned to provide the Natural Environment Research Council’s Autosub programme with an up–to–date review on the law relating to autonomous underwater vehicles. AUV operations are sufficiently novel that guidance on operating practice and the legal constraints that may apply has been rather scarce.
By the nature of the commission, the report focuses on the national and international legal regimes applicable to a UK operator and as they appertain to an autonomous vehicle engaged in marine scientific research, such as Autosub. Nevertheless, much of this authoritative publication is relevant to the international operation of an AUV of any nationality and it will also prove valuable to commercial operators.
As an aid to dialogue, it should also prove valuable to those in the maritime law community interested in the questions posed by this exciting new underwater technology.
Guidance Notes for the Planning and Execution of Geophysical and Geotechnical Ground Investigations for Offshore Renewable Energy Developments
ISBN 0 906940 54 0, ISBN 13 978 0 906940 54 9 Perfect bound, 48 pp, Colour Price: Non-members £15, members £13.50
The Offshore Site Investigation and Geotechnics (OSIG) Group of the SUT is pleased to announce its Guidance Notes for the Planning and Execution of Geophysical and Geotechnical Ground Investigations for Offshore Renewable Energy Developments.
The past few years have seen a proliferation of offshore renewable energy projects including wind, wave and tidal developments. Some of the more significant risks that the developers of such projects face are the hazards and uncertainties that ground conditions present to project development, design, construction and operation.
The impact of these risks can be exacerbated by the increasing size of offshore renewable developments.

The Offshore Site Investigation and Geotechnics (OSIG) Group of the SUT is pleased to announce its 7th International Conference, ‘Integrated Geotechnologies – Present and Future’. This conference will continue the aims of this established series, started in 1979, of disseminating and communicating the latest developments in all aspects of marine geotechnology.
The needs of the offshore industry have evolved substantially since the first conference held in 1979. While foundation developments continue to be important, there is now greater emphasis on integrating marine geology, geophysics and geotechnics. New challenges are being presented in geohazard assessments and geotechnical aspects of renewable energy, deepwater developments, floating production, pipelines, subsea tie backs and new environmental conditions.
Exciting developments for this conference included hosting the inaugural Bramlette McClelland lecture, organised by the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) in commemoration of one of the pioneers of offshore geotechnical engineering. The conference also held combined sessions featuring papers from special offshore issues of Géotechnique and Near Surface Geophysics, both leading journals in their respective specialist fields.

The long established international conference dealing exclusively with underwater instrumentation, control and communication for subsea oil and gas production has been structured to cover relevant experience and new thinking in subsea developments. Providing a unique forum for the supplier and operator of subsea technology to exchange views and experience, its aim is to bring together the many diverse disciplines engaged internationally in this technology. Experience gained and current challenges, as well as new advances in technology, will be the main topics to meet the future challenges. Equal importance has been placed on reliability and global issues such as environment, decommissioning, deepwater problems and long distance offsets. These proceedings will feature contributions from professionals giving experience gained and new challenges to overcome and is therefore of interest to all in subsea engineering.
