Duva Project

Located 14 km northeast of the Neptune-operated Gjøa oilfield at a water depth of 340 metres, the Duva project is the Neptune's first discovery in the Norwegian North Sea.

The project, coated in Q4 2020, was developed as a subsea installation with three oil producers and one gas producer in a tie-back to Gjøa.

The objective of the project was to reduce well interventions, chemical injections, and scraping activities during the operation of the well.

Shawcor was selected to apply LotusFlo^® on downhole tubulars for the Neptune Duva project to reduce and eliminate deposition of inorganic/organic solids on the ID of the pipe. LotusFlo is a super hydrophobic, ultra-thin, internal Diamond-Like Coating (DLC) designed to reduce and possibly eliminate deposition of scale, asphaltenes and wax on tubular surfaces. LotusFlo is also the only DLC product available in the market for large-scale production.

The application of LotusFlo on Duva project was of strategic value for Shawcor as the first application in the North Sea fields. “We expect this to be the first of many opportunities in the North Sea region,” said Mauricio Toledo, Shawcor.

Despite challenges caused by the COVID-19 pandemic, the subsea execution schedule was delivered on time. The production capabilities, operational efficiencies and cycle times were all managed by the Shawcor team. As a result, another project was successfully completed with zero safety incidents, while meeting project schedule and quality requirements.
