National Oilwell Varco

Introduction

When staff at National Oilwell Varco were unable to build tall manifold assemblies due to the restricted height of their Dunfermline factory, they turned to Surespan for help. Opening up the roof on a temporary basis was the solution.

We supplied

Surespan supplied multiple hatches including;


Following consultations with our design team, Surespan manufactured a 4000 x 4300mm double leaf roof hatch which enabled an external crane to lift the manifold units in through the roof. The electrically operated hatch opens in an automated sequence, controlled by a small PLC and activated by the turn of a key. It was specially designed to open and stay open utilising strut locking to withstand agreed wind conditions.

This solution allowed the company to continue this operation in their existing factory without having to hire temporary premises.
