What We Do
Maron Systems offers its proven Oil logistics, Accounting and Shipping system (OAS) which includes extensive facilities and support for the whole Order Lifecycle, from input by Traders through to document generation at the jetty and mass balance by the Stock Accountant.

OAS has been installed in a number of countries, already counting many major multi-national oil companies amongst its users. Catering for a wide range of solutions, OAS has been developed in co-operation with real refineries and real users ensuring that it delivers real benefits.

OAS offers reduced costs, more accurate information sharing, and improved process efficiency in an integrated solution. OAS is also very cost-effective. A typical implementation payback period could be as short as 12 months.
