Maria Development – Selected Concept Kristin (HWU):
Åsgard:
Production, power, chemicals, surveillance and control The key Maria Host Platform
Heidrun:
Gas lift supply to the existing Tyrihans line Crude oil storage and offloading via HWU
Sulphate reduced injection water treatment and supply
Maria: Gassled: Gas transportation and processing
Subsea production system, wells and infrastructure
Tyrihans: Transportation of lift gas from Åsgard B to Tyrihans D for Maria production wells

Maria Project – Challenges
Flow Assurance Challenges
Need for both well gas lift and riser gas lift for production, start-up and flow assurance purposes
Production pipeline heating for hydrate (and wax) management
Pipelines and Umbilicals
Extensive number of coral reefs and iceberg scars in the area
Complex risers for both umbilical and DEH due to combined functions and riser slot limitations
Subsea Production System
Fluid production temperature expected to be high (>121oC)
Connection to 4 different units (production licenses)
Multiple commercial agreements are needed in time
Project execution depends on a series of ‘part projects’ with other licences/units
Maria Project - Opportunities and Benefits Opportunities and Benefits Cost effective concept with limited modifications to each host platform – Maximising use of existing infrastructure – Should stand as a front runner and example for later developments
Maria utilizes available existing capacity and multi phase metering principles Potential for additional tie-backs and continued production on hosts Kristin
