SeaQuester | Offshore CCS System

The project SeaQuester has defined a new system for the disposal of carbon dioxide in offshore reservoirs. The Carbon Capture and Storage (CCS) system allows for the loading, conditioning and compressing of gaseous carbon dioxide (CO2) into high pressure storage facilities onboard a bespoke carrier vessel. The vessel sails to location, hooks up to a … Read more

FFI | Conceptual for Offshore Green Ammonia

The project FFI is looking at using renewable energy resources to produce green hydrogen and green ammonia in order to decarbonize its own fleet of trucks and vessels as well as commercialize H2/NH3 as fuel. FFI has then investigated the best way to transport H2 by using existing sea transportation solutions. Scope of Work DORIS … Read more


DORIS provided CAPEX and OPEX optimisations for BONAPARTE FLNG The development concept consists of two integrated segments: The FLNG vessel could be redeployed to other areas at the field end-of-life.  The proposed floating liquefaction plant will utilize the gas from the Petrel, Tern and Frigate natural gas fields to produce LNG and the FLNG is anticipated … Read more
