This joint publication by the Oil Companies International Marine Forum (OCIMF) and the Chemical Distribution Institute (CDI) provides clear recommendations and guidance for oil tankers, chemical tankers and dual classed oil/chemical tankers with the aim of achieving improved safety, standardisation and compatibility with terminal facilities.
It provides a significant amount of new tanker industry accepted recommendations on safety and equipment, including additional tonnage categories and recommendations for ship owners.
Areas covered include manifold position and design, working platform and spill containment, hose support, bunker connections, lifting equipment, deck fittings to facilitate hose handling at buoy moorings and connectors for ship/shore emergency shutdown equipment.
