Assessing upstream asset performance with Maintainability, Availability, Reliability and Operability Simulation.

MAROS, which stands for Maintainability, Availability, Reliability, Operability, Simulation, is an advanced RAM tool with extensive features for modelling networks, maintenance, operations and demand scenarios which includes powerful Boolean logic option.

For the design stage it permits the development and comparison of systems by predicting their life-cycle behaviour pattern. Comparisons can be made of the most elementary concepts in the early stages of a design project when few details are fixed (or known), while at the other extreme complex systems can be optimized to yield maximum cost-efficiency. As its acronym suggests the package encompasses well known 'types' of analyses which have been successfully integrated into a simulation algorithm and offered as a design aid. Users don't need not be specialists nor have an intimate understanding of the mathematics involved, emphasis is placed on 'engineering' a system to cope with its lifetime design requirements. In this way, the life-cycle approach guides the user to consider and optimise maintenance and operational strategies of the system as well as its initial design layout.

Maros - result output, predicting average future production and losses

Purpose
Maros was originally developed for the offshore oil and gas industry where it has been used extensively to design process facilities and transportation systems to exploit hydrocarbon reservoirs. As a general purpose systems design tool it is currently used in a wide range of applications including chemicals, power generation and distribution, manufacturing etc.

Its particular applications involve the following aspects:

• equipment reliability and redundancy
• establishing maintenance and intervention strategies
• system productivity and sales quota fulfilment
• system operability assessment
• operations research

Benefits
Maros is one of the world’s leading tool for RAM in the upstream Oil and Gas industry.

• It is tailored to accommodate the very specific system configurations and operations present in the industry.
• Particular operational complexities supported are flaring, multiple products, time-varying reservoir profile and time-varying sales demands.
• The development team has a long history of working closely with advanced users, mainly the biggest Oil & Gas companies around the world, which ensures basic and advanced needs associated with availability analysis in oil and gas operations are met and supported by Maros

Maros is the most usable tool for RAM in the oil and gas industry

• The user interface provides flexible ways for defining and manipulating input data to allow the user to focus less on input operations and more on using results to improve the performance of the system
• The study organisation reflects the real world and provides intuitive management of the system under analysis
• The results are presented with industry standard terminology and provide information on real world numbers that are easy to understand

Maros has great flexibility to handle complex configurations and situations outside the normal scope

• The software has several features that allow the users to reflect situations not initially thought about in ways that seriously challenge the most powerful generic reliability simulation models
