Holleman transports different equipment for refineries, mainly related to their modernization: Brazi, Teleajen, Navodari in Romania and Burgas in Bulgaria. We have also transported oversized oil equipment, mainly with the occasion of relocating different drilling and boring installations.

Other examples of equipment transported by Holleman in oil, gas and petro-chemistry industries: cox vessels, condensers, steam drums, different columns etc. For the execution of these, often the means of road transportation were combined with river and / or deep-sea transportation, depending on the complexity of each project, to which specific handlings were added by cranes and hydraulic gantries.

There were also oversized transportations (with long length and significant weights) performed on two trailers, with turntables.
