English to Lithuanian Tech/Engineering Energy / Power Generation

Some context where this term appears in the operating and maintenance manual:

"Skid for vessels
Vessels (delivered loose):
Hydrogenator / Desulphuriser"

"Adsorber vessels"

"Anchor bolts may only be fixed by casting after installation and alignment of equipment such as vessels, skids, interconnection piping!"

"It is recommended to place the supports onto the foundation before bolting the reformer vessel."

"After levelling and alignment of all skids and vessels, they can finally be fixed on the foundation plate."

Thank you for your help in advance!
