Effects of Drilling on Deep-Water Seabed Communities
Daniel Jones, Andrew Gates, National Oceanography Centre, Southampton
Data collected by the SERPENT project on the effects of drilling on seabed biological communities will be presented. Effects are evaluated across a range of scales: from effects to individual organisms to effects to whole communities. The data obtained on metabolic changes in a common starfish shows the value of small-scale experimental assessments in understanding broad effects. A synthesis of broad-scale community data shows common effects across the northern North Atlantic. In addition, data on recovery of communities from drilling after three and ten years and show evidence of partial recovery after 10 years except in areas with deep cuttings and cement will be discussed.

16:45 – 17:15    Waste Management
Moderator: Janike Myre, Executive VP Business Support & QHSE, Odfjell Drilling

Long Term Liability and Waste Management
David Perez, Transocean
Mismanagement of waste generated by your company can impact stakeholder health, environment, shareholder value, individuals, company and the drilling industry as a whole. In some countries, environmental regulatory requirements for waste management are in place however no infrastructure or enforcement exists. It is necessary to develop a comprehensive and verifiable waste management plan not only there but wherever the company operates. Long-term liability associated with mismanagement of waste is far reaching and can negatively impact the environment, your company as well as the drilling industry. Sound waste management is a Corporate Responsibility.

09:00 – 09:30    Opening Remarks
                        Steve Kropla, Group Vice President - Operations & Accreditation, IADC
                    
Keynote Presentation: Ensuring Access to Offshore Oil and Gas in a Multiple- Use Marine Environment
Paul Holthus, Executive Director, World Ocean Council
Mr. Holthus will review the issues and stakeholders critical to the future of offshore oil and gas operations, and outline strategies and priorities for leadership and collaboration with other ocean industries to address ocean sustainability and ensure access to resources.

09:30 – 11:00    Panel Discussion: "Continuous Discharges, What Can be Improved?"
Moderator: Gert-Jan Windhorst, Manager HSE&Q Europe, Noble Drilling (Nederland) B.V.

To reduce discharges, it is important to focus on prevention, use of risk analyses in decision making and operations, look at new technology and learn from lessons from the past. The purpose of this panel discussion is to create awareness and gather ideas for environmental improvements.

Moderator: Thor Blunck, Drilling & Completions Department Manager, Total E&P Norge

The New Logistics and Waste Disposal Concept of the Mittelplate Offshore Rig
Dirk Kowalczyk, RWE Dea AG, Arnold Wachtendorf, M-I SWACO Deutschland GmbH
The installation of a new rig as part of the Mittelplate offshore production facility (with RWE Dea AG as the operator and Wintershall AG as its partner with shareholdings of 50% each) in late 2005 enabled a continuous drilling programme with highly deflected well distances to be set up. A new logistics and waste disposal concept had to be developed and implemented, taking into account that the offshore installation is located within the Schleswig-Holstein National Park and Mudflats nature reserve, and also to optimize the already successful Mittelplate HSE package.

Marine Biofouling and its Control
Anthony S. Clare, Newcastle University, UK
Marine biofouling is an age-old problem that continues to hamper the efficiency of maritime activities. Fouling species are pre-adapted to occupy available space on unprotected artificial surfaces, which can therefore be colonised rapidly following immersion. The use of biocides is the most effective means of controlling biofouling, but there are attendant environmental concerns that are leading to ever stricter regulation. Nontoxic approaches, including fouling-release coatings, hold considerable promise, but do not necessarily prevent fouling. There is thus a danger that in seeking to reduce biocide usage, the potential for transporting invasive species is increased.

Globalization and the Threat of Invasive Species to Marine Biodiversity. The Mobility of the MODU under Increased Scrutiny
Franco dos Santos, Noble Drilling (Nederland) B.V.
Within the marine and regulatory community there has been an increased awareness of possible biological contamination when relocating MODU’s. The dangers involved are discussed from a drilling contractor’s point of view, and we will use a case study on the preparation of a rig moving into the European waters from a distant location, as being representative of our thesis.

13:00 – 14:30    Luncheon & Open Exhibition

14:30 – 15:30    Sustainability
Moderator: Svein Flornes, QHSE Advisor Polar Pioneer, Transocean

Can UBD Flaring Reduce CO2 Emissions?
David Elliott, Shell International E & P, John Ramalho, Shell SIEP
An evaluation of the trade off of increased CO2 emissions from UBD flaring against reduced CO2 emissions from fewer required wells, reduced steel requirements and reduced rig time. Case studies of several Shell UBD projects will be presented to determine the “CO2 cost neutral point” and if the projects reduced or increased global CO2 emissions. Conditions under which UBD may be justified to reduce project CO2 emissions will be determined and discussed.

The Green Rig
Malgorzata Krupa, Maersk Drilling
The purpose of the Green Rig project is improving the environmental impact from the rig fleet. The project focuses on four main areas: energy efficiency and emissions, discharge, accidental spills and waste management. The project involves an awareness campaign amongst the Maersk Drilling employees and results in environmental improvement proposals.

15:30 – 16:00    Networking Break & Open Exhibition

16:00 – 16:30    Technology to Maximize Environmental Stewardship
Moderator: Anne Vegge, Vice President HSE & QA, Dolphin Drilling

A Green Rig
John Skeggs, Odfjell Drilling
Installations and arrangements to provide these green rigs, including: enclosed derrick preventing mud spills to sea; all drain lines routed to a central cleaning unit; discharge from mud pits by pumping, no gravity discharge; low emission of NOX, clean design engines; closed loop BOP control system; electrical draw works with power regeneration; and waste management systems will be outlined.

Unassigned Papers of Note:
The following papers proposals will be included in the conference if a scheduled paper becomes unavailable. In addition, these presentations will be made available in the IADC conference proceedings, should the author so desire.

New Developed Riser Cleaning and Displacement Tool Offers Environmental Benefits
Erling Kleppa, Petroleum Technology Company, Nina Aas, Scott Kerr, Eivind Svendsen, StatoilHydro
The Riser Cleaning and Displacement Tool will prevent mixing of drilling fluids and sea water when disconnecting a marine riser. This is environmentally beneficial as there is no need to transport and destruct slop. Also, no new drilling fluids needed to be made to replace lost drilling fluid. It does not require any extra rig time compared to standard operation as the tool is part of hang off equipment. A cost reduction of 1-2 million NOK is obtained in reduced slop and handling costs.

Controlling Cost and Environmental Integrity in Drilling Fluid and Drilling Waste Management
Johan Pettersen, Christian Solli, MiSA – Miljøsystemanalyse, Bjørnung Jensen, John E. Paulsen, Onsite Treatment Technologies
Transparent consideration of compliance is important for the environmental integrity of drilling fluid and drilling waste management. A model to meet the demand for technology evaluation and stakeholder communication is presented. Selected examples of parallel consideration of cost and environmental performance are illustrated, showing the cradle-to-grave approach with multiple environmental and cost performance measures. The model form is generic in order to offer decision makers the flexibility and opportunity to highlight local priorities. Transparent benchmarking of drilling fluid and drilling waste technologies is ensured using an extended evaluation scope, solid environmental information and standardized environmental management methods.
