Project Updates
CNR Olowi
The CNR Olowi development, in offshore Gabon, achieved 1st Oil in April 2010. CNR developed the field using three wellhead towers and one conductor-support platform featuring up to 44 well slots, which was then linked back to a floating production, storage and off-loading (FPSO) vessel, the Knock Allan.
Cirrus Egyambra Feasibility Study
PDi have been supporting the CNR project management team since 2006, in developing the concept, defining the engineering scope, support during the tender phase, managing the installation contractor through the engineering preparation, fabrication and installation phases. The PDi core team were supplemented during the project life cycle with specialist PDi discipline support for discrete work packages and co-ordination of the Offshore Construction Clients reps which accounted for circa 1,000 man days.
PDi have recently completed a 20 month feasibility study for Gulf Bay Developers Ltd (a special purpose joint venture company formed by Cirrus Energy Services Ltd and the Ghana Ports and Harbours Authority). The study is for the development of an international deep sea port at Egyambra in the Western Region of Ghana, to serve the adjacent offshore oil & gas industry and act as a storage and distribution facility.
As the appointed project management consultant for the development, PDi have overseen: -
* Project Inception Study
* Viability Site Investigations
* Detailed Bathymetric and Geophysical Survey
* Feasibility Study (including; concept selection, technical feasibility, CAPEX estimate, development of financial model, stakeholder engagement and environmental impact scoping)
PDi continue to support the development as it moves into the FEED phase, including the Environmental Impact Assessment.
Recognising the importance of the development, Ghana’s President John Atta Mills said in his state of the nation speech in February; “Ghana is poised to be a major producer of oil and gas and I have instructed the Energy Ministry, in collaboration with the Ministry of Transport, to fast-track investments in the necessary infrastructure, including a deep sea port with dedicated oil service facility and the rehabilitation of the western railway corridor. These flagship investments will not only create significant employment themselves, but will also support the growth of other industries.”
Maersk Decommissioning
Decommissioning the Leadon Subsea Infrastructure. Commenced with FEED study and followed onto preparation and submission of decommissioning programme. PDi are supporting the project through execution of the decommissioning programme and into the ongoing monitoring.
PDi were engaged by Maersk to initially perform a FEED study for the decommissioning of the subsea infrastructure at Leadon. The Leadon Field consists of a pipeline bundle, two towheads (307Te and 275Te), a midline structure (282Te), six riser bases (ranging from 50-95Te), 4” flexible flowline, numerous tie spools and jumpers. Following on from the FEED study work, PDi were tasked with the preparation of the decommissioning program for submission to DECC, which was developed following completion of a comparative assessment , E.I.A., Risk Review, Supply Chain assessment, review of ongoing liabilities for the proposes options. . This is the first bundle ever to be considered for decommissioning and there is significant interest from all stake holders in the decommissioning programme which is scheduled to be submitted to DECC July 2010.
Apache
PDi are currently supporting Apache North Sea Limited with the provision of experienced Construction and Installation personnel during the initial phase of the new bridge linked Forties platform.
The Front End Engineering and Design work by SLP working with Altra has commenced with completion scheduled in the third quarter this year. SLP North Sea will be taking responsibility for design for the new platform jacket, topsides and a bridge-link to the existing Forties Alpha platform, with the intention that the FEED work will lead to Apache sanction and subsequently on to an EPIC contract award for SLP NSL later this year.
Chrysaor
Chrysaor are in the process of developing the Solan Field located in block 205/27 west of Shetland, in 135m meters of water. The development plan consists of the installation of an Articulated Tower and Storage Tank (ATT) structure, drilling production and water injection wells and the installation of subsea flowlines and control umbilicals. The ATT consists of a GBS with a cylindrical steel tower attached by means of a universal joint arrangement; the topsides module is supported by the tower while the tank acts as an anchor for the tower and provides oil storage capacity.
PDi have been engaged to provide support during the concept phase, through FEED and in to detailed design with particular focus on the following:
* Installation Cost Estimate & Schedule
* Decommissioning Cost Estimate & Schedule
* Field Layout Design
* Flexible Flowline / Riser Installation Methodology
* Preparation of Invitation To Tender (ITT) Scope of Work
This is technical challenging project, that involves towing, ballasting and flexible flowline installation which has drawn on the expertise of a multi-disciplined PDi team since October in 2008.
North Idku Project - RWE Dea Egypt - Project Management Services
PDi Mediterranean continues to support RWE Dea in the North Idku Development Project with a contract providing Project Management Services throughout the detailed engineering / procurement, fabrication & construction and commissioning phases; following 4 years of providing consultancy services at earlier stages of the project.
Erich Varchmin is heading up the North Idku Project Management Team comprised of a project management services team with complete project specialties; ranging from contracts and procurement, planning, cost, engineering design, pipelines, structures, QHSE, through to document control.
