This presentation contains information about the Dunlin A Platform. The platform was installed in 1977 and the Osprey Module added in 1990. The information is based on the original construction drawings.

The 3D Model section contains an interactive 3D model which can be viewed from different angles. It has a structured component tree allowing interaction with labelled equipment within the model.

This work comprised an engineering study investigating the operational issues concerning the replacement of the Anasuria Swivel Stack.

The equipment and procedures shown were based on the original design information. The worksite and the layout of the Turret Structure were imported from an existing PDMS and subsequently updated and cleaned up for clarity.

The Dunbar field, situated 22km south of Alwyn North, first produced oil/gas in 1994. Dunbar comprises a steel jacket platform together with drilling and accommodation facilities. Throughout recent current drilling campaigns, the Transocean Sedco 706 semi-submersible had been anchored alongside Dunbar to provide Tender Assist to the Drilling functions. This project provided an overview and offshore induction to the operations involved in hook-up and hose connections, including installation and operation of the Quick Disconnect couplings.

This presentation describes the replacement and bypass of the Cell Import/Export Manifolds and 10" Cell Fill Lines located in the Utility Shaft of the Brent Bravo platform. The construction activity installed a new Import/Export Manifold at EL +87m, above the existing equipment at the Cell Fill Manifold level.

The conversion from existing to replacement Cell Fill Lines required the isolation and removal/replacement of the relevant existing Cell Fill Lines. A general description of the work area and its location was provided, with a brief introduction to the function of the main systems contained within the Utility Leg.

The Starling well fluids are brought onboard Shearwater 'A' Platform through a new Riser. The well fluids are routed through a new ESD Valve and wet gas meter to tie-in points on the existing Production and Test Separator lines. The Starling facilities were contained in two prefabricated modules located above the existing Scoter Module.

This project included the development of step by step installation procedures for the Starling Equipment and tie-in pipework.
