An overview of the services you offer and how they will benefit the visitor.
Maintenance And Repair Services
Ensuring that equipment is correctly maintained is at the core of IEC 60079-17 as well as the equivalent international standards. Following any inspection cycle, records of any issues or repairs identified should be provided to allow for the correct prioritisation of defects raised.
As standard Larnark provides these results in an easy to understand format, utilising a simple category system to give a clear means of identifying critical repairs or non-conformances found; this aids in the correct prioritisation of their criticality for safety and compliance.
Larnark can assist in the completion of your hazardous area maintenance by supplying qualified and experienced personnel, suitable equipment and informed engineering guidance to identify the most cost effective method to implement the remedial actions raised.
All completed repairs are followed up with a re-inspection of the equipment and update of inspection records to close the loop on each items’ compliance.

PETROCHEMICALS & INDUSTRIES
Larnark provides a proven multi-disciplined team that can deliver greenfield and brownfield petrochemical & utilities projects. Our team and partners are able to collaborate closely with clients to produce fit-for-purpose designs that meet safety, quality, cost and schedule requirements.
From a commercial standpoint, Larnark offers a balanced and flexible contractual approach to each project, based on the needs and preferences of the client and with the objective of balancing risk between contractor and client; with a focus on:
- Refinery Process Units.
- Petrochemical Facilities – generation and processing plants.
- Manufacturing Facilities
Water Treatment, Pump stations, and Wastewater facilities.
Our capability spans the full spectrum of EPCCM services, from concept and front-end engineering design through to detailed design, procurement, fabrication, construction, commissioning, operation, and maintenance.
We have the knowledge and expertise to ensure all aspects of engineering, procurement, construction and plant operations are aligned to meet scheduled shutdowns and minimise disruption during construction. And our construction methodologies include a well-defined construction sequence that maximises offsite pre-assembly of equipment.

Operation and Maintenance
With extensive global experience across a diverse range of industries, Larnark brings the latest Innovations and Technologies to our client to ensure the safe operations and maintenance of installed equipment at all stages of the life cycle and with strict adherence to health, safety, environmental and industry regulations.
As the lifespan of the system comes to an end, Larnark can also review best options for the potential of a refurbishment or repowering and long-term resource forecasts. In addition, Larnark can propose the best options within the current market technology and can provide a review of system performance and market value.
