Callenberg provided HVAC solutions to a 6th generation type MOSS CS60 semi-submersible drilling rig.

The scope of work included detailed system design review, procurement and equipment delivery for both the HVAC systems and the provision RFN systems. Callenberg was also responsible for commissioning and startup of these systems covering drilling & utility areas, columns & pontoons and a 150 man living quarter.

The equipment packages included HVAC control systems, Air Handling Units, fan coil units, water chiller units and related auxiliary equipment.

As this rig was designed for operating in harsh arctic environments it was fully winterized, with special consideration for the heating stations and air intake louver solutions.
