After successful development of almost 200 ‘Inventory of Hazardous Materials’ MARSIG offers a new service for the continuous update of the reports (see EU Reg. 1257/2013). Such update is essential for the maintenance of the IHM Certificate but might put additional time requirements on a purchasing department of a shipping company and its fleet.The service is independent from the contractor of the initial IHM report or from the classification society which carried out the onboard certification. It may comprise various Service Levels, from simple database update till comprehensive classification and completion of purchase orders and their accompanying documents. On the wider range of Service Level MARSIG also requests suppliers for necessary documents and clarifies the installation of components on board the vessels.
