The Crown Estate has launched an invitation to tender for the role of data handling support in the management of the Marine Data Exchange (MDE) for a period of three years with effect from 1st April 2019.

By making valuable data freely available, we hope to promote collaboration within the sector, reduce survey costs and ultimately de-risk investment offshore.

To supplement our in-house resources The Crown Estate wish to appoint a company to support our team with the data handling tasks critical to the effective running of the Marine Data Exchange.

The requirement is for a company with a small team of professionals familiar with marine data management standards and offshore survey data, to provide data support according to agreed standards, methodologies and deadlines.

The deadline for initial bid submissions is COB Friday 19th October 2018. Bidders may be invited to attend an interview between 12th and 30th November. There will also be an opportunity to get an introductory demonstration of the MDE at The Crown Estate between 24th and 28th September.
