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



Weight restrictions for host platforms requires simple topside solutions (multi phase metering)

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
