Chirag-1 Platform, Caspian Sea

Atkins was commissioned by BP to assist in an independent review of the installation failure of a directionally driven conductor pile. Particular attention was paid to the drivability of the 24inch conductor which had an 8ft long 22mm offset shoe. Predicted driving performance was compared with measured blowcount records, hammer energy levels and pile stress information.

Safety and Risk Implications of Recent Trends in Marine Ground Investigations

The offshore oil and gas industry is pressing ahead with exploration and production from reservoirs in ever deeper water. As a result, there has been a progressive change in the type of structures and seabed infrastructure being deployed. New technologies and methods of working and reducing costs involve new risks or a change to the importance of previously well-understood risks.

Atkins was commissioned by the UK Health & Safety Executive to review how the offshore industry has recognised and manages the risks associated with the new methods of geotechnical characterisation and analysis, and the consequences for safety.

Malampaya Gravity Structure, Philippines

The Malampaya Development is a project to supply gas to power plants within the Philippines. It includes a concrete gravity structure (CGS) production platform which also has a process plant and is used to store the condensate. Atkins was commissioned to provide a tender design for the CGS. Our specialist geotechnical activities included:

design of foundations and scour protection for the CGS•seismic design aspects of the CGS casting basin•dewatering and sideslope designs for the CGS casting basin•

Beatrice Windfarm Development - Feasibility Study, Scotland

The Beatrice Field was identified as a possible site for the installation of an offshore wind farm in the Moray Firth, in approximately 45 metres water depth. To assess the development potential, Talisman requested Atkins investigate the feasibility of installing a number of Offshore Wind Energy Conversion Systems at the Beatrice Field. The study included wind availability, turbine technology and substructure and electrical power aspects.

Brent Flare Decommissioning, North Sea

Atkins investigated the geotechnical aspects of the decommissioning of the skirted gravity base of the Brent Flare articulated buoyant tower.

The results of previous JIP studies carried out by Atkins for 1st generation concrete GBSs were applied in a semi-quantitative manner to the Brent Flare structure by considering the following factors:

actual dimensions of the structures•actual soil type and stratigraphy, strength and permeability •characteristicsskirt layout and embedment depth•the maximum available positive bouyancy / uplift•measures to assist the break-out operation (e.g. underbase water •injection)

Conductor Study - Joint Industry Project DEA(E) 101

The aim of this Drilling Engineering Association (Europe) JIP was to investigate available methods of analysis for the lateral loading of subsea well conductors, to validate the results against the results of field tests, to identify any over-conservatisms in existing analysis methods, and to make recommendations for improvements in conductor analysis and design.

A programme of detailed analysis was undertaken using a variety of approaches, including the conventional p-y method and advanced finite element methods. Full three-dimensional finite element modelling was undertaken using the ABAQUS code.

Several organisations were involved in the project. Atkins was project manager and also responsible for technical direction and analysis.

Seaflow Marine Tidal Current Turbine, UK

Following a contractor’s unsuccessful attempt to install a 45m long monopile in about 24m of water, at a location offshore Foreland Point in Devon, Atkins was commissioned by MCT Ltd to:

assess the engineering geological characterisitics of the seabed and •sub-surface ground conditionsreview the design of the original monopile and casing configuration •and the procedures followed for the first installation attemptevaluate a modified design of the monopile, casing and installation •technique, as proposed by the marine drilling contractordevelop possible alternative designs and associated installation •requirements
