There are no national or international codes covering the sort of structures concerned, and so techniques from structural building codes and in-house methods are used to produce a safe and serviceable product.

The services provided cover:

• Calculating the weight of the boiler and its contents
• Design of sling systems on which the boiler hangs
• Design of restraint systems locating the boiler subject to seismic and wind loads and interfacing plant thrusts
• Design of buckstay systems bracing the boiler walls against gas pressure excursions and combustion-induced pulsation
• Design of all of the other miscellaneous structures supporting and bracing the boiler walls and internal heating surface
• Mechanical design of casings for economizers and ash hoppers where these are integral with the boiler
• Mechanical design of penthouse casings and any other remote casings
• Production of technical specifications for purchase of relevant materials and out-sourced design and manufacture
• Production or review of relevant parts of erection and operating instructions
