Operations Assurance &
Maintenance Process

Nexus engineers and operations specialist can provide major capital “Oil & Gas” projects with “Operations Assurance” services from design stage to construction and commissioning / start up of complex facilities.

 

Nexus utilizes a proven and structured process to integrate Operations Assurance into major capital projects.

 

Nexus ensures that Operability, Reliability and Maintainability is the corner stone for its Operations Assurance process.
Nexus Operations Assurance process reduces OPEX (Operating expense) over the life of the facility for a fraction of the cost of the project’s execution. (The cost is often less than 5% of the project cost).

 

Most importantly, the Nexus Operations Assurance process provides a more predictable operating performance for the life of the facility.

Today, process documentation designed and deployed by Nexus Alliance guides and controls the daily operations of several of the largest plant facilities in West Africa. Our input minimizes downtime, maximizes operational efficiency, and maximizes the plant lifecycle – thus delivering significant and quantifiable long-term value to our clients.

 

In addition, true to our focus on operational excellence, we are recognized as an industry leader in the deployment and management of Computerized Maintenance Management Systems (CMMS).

Reliability Centered Maintenance (RCM) for Escravos Produced Water Disposal (EPWD) project.

Nexus in partnership with Advanced Reliability Technologies (ART) carried out RCM studies for the EPWD project utilising ART’s RCM ReliaBuilder software to document the results and analyse the project.

 

The process led to a reliability-based proactive set of tasks focused on maintaining the desired functionality of systems and equipment. The process also identifies equipment for which it is most cost-beneficial to allow to ‘run-to-failure’, due to low economics, safety or environmental impacts
