In shipyard preservation lines, sheets and profiles are thoroughly blast cleaned and provided with a temporary corrosion protection coating. Along with the external transport unit, a preservation line consists of a pre-heating oven, a pass-through blasting machine, a painting unit and a drying tunnel with its associated slat conveyor.

Generally, shipbuilding, ship conversion and ship repair activities require a wide spectrum of work and services which include works on steel structures, piping systems, corrosion prevention, carpentry, electrical, engineering and mechanical systems. Ship conversion generally involves the conversion of vessel type for different function, for example, the conversion of a cargo vessel to a livestock carrier, jumboisation of vessel and FPSO/FSO conversion. For converting a vessel to an FPSO, in addition to the works mentioned in the above, different process modules will need to be fabricated so that the vessel can carry out oil and gas exploration and production work.
