BMT Isis (BMT), a subsidiary of BMT Group, the international engineering, maritime and risk management consultancy, has recently completed a berth capacity study for Knauf ahead of significant planned investment for its jetty located on the Swale in the south east of England. The Grovehurst Jetty near Ridham Dock is operated by Knauf to import and transport gypsum to its factory in Sittingbourne, Kent where the mineral is used to produce plasterboard. In a bid to assess the feasibility, identify the effects and estimate the likely costs of changes to the gypsum import process, Knauf turned to BMT for a transparent and impartial assessment.
