Balance of Plant skids for chemical process sidestreams and environmental control equipment
Power generation and boiler plant services equipment as Balance of Plant modules
BoP modules for Motor Ships and marine propulsion equipment


Arguably, the modular Balance of Plant concept appears to have originated in the marine industries during the early1960s, when companies such as Rolls-Royce, Serck Heat Transfer and Coventry Radiator were pioneering drop-in services packages. Skid-mounted generating units, along with fuel oil conditioning, lub oil cooling and filtration BoP modules for motor ships were installed into position whilst fitting-out, and could be exchanged from the dockwall on a single tide. This anticipated the automated engine room, and present day ship management practices.


Dove Thermal has been designing and building Balance of Plant modules for over thirty years. The advantages of bringing together all services necessary for a core application are of particular value in the pre-engineering of complex systems, when site access is in some way restricted, or when installations are to be made at remote worksites.


Initially applied to power generation and boiler plant, the concept extends to modularized test plant ancillaries, chemical process sidestreams and marine propulsion equipment. From a contractual viewpoint, a BoP service module places responsibility for the supply and commissioning of bought-in equipment with a single source, whilst in terms of project management, the component count of deliverables is much-reduced. Having regard to integrity of supply, the transport, storage and security of a single item is more readily arranged.

Power Generation

The isometric shows a skid that we designed for a packaged turbine generator. It brought together pumpsets and heat exchangers, oil & water tanks, and environmental control equipment, with local panels, variable speed drives and prefabricated wiring looms.
