Our company skill set allows us to tackle challenging offshore, marine and naval projects to your requirements.

OC knows that when you’re out in deep water and counting on your equipment, it has to be done right – the first and only time.
Marine and offshore HVAC/R systems
Whether you require offshore or marine engineering and consulting services, beginning-to-end project management for marine, offshore or naval projects, or HVAC/R construction, manufacturing and support, OC can get the job done.
We have developed a range of HVAC products specifically for the marine and offshore oil and gas industry with an excellent solution for HVAC in shale shaker rooms with near laminar flow. This solution has been used for HVAC in high-pollution areas too, which has allowed smokers and non-smokers to be in the same room without the non-smokers being able to smell the tobacco smoke. Our 40,000m³/hr (145mm WG) HVAC supply cabinets have been designed for room noise level of 50dB(A).
HVAC products have been designed specifically to meet the stringent requirements for marine and offshore applications. To develop mariner equipment, it was necessary go back to the basic equipment and design from the bottom up and establish a design to ensure long equipment lifecycle and reliability. The key to our product design is flexibility in design, capacity, dimensions, materials and area classification.

Offshore HVAC system design and installation
HVAC systems are designed and installed with the utmost care and thought given to the reliability of the design and equipment performance at the lowest cost and weight, and for the required equipment lifecycle.
Detailed air pressure drop calculations for the installation are always carried out. Motors and drives for AHUs or fans are selected on this basis. Engineering documentation is of the utmost importance through all phases of installation.
