					       Updating of Crisis/Disaster Management Plan for Visakhapatnam Port Trust

       The Port of Visakhapatnam, a natural harbour nesting among a chain of hills, was opened
to commercial shipping in 1933. It is a statutory requirement for VPT to delineate a disaster
management plan to effectively deal with all kinds of Port hazards. In this regard, VPT requested
NEERI for updating of the existing disaster/Crises Management Plan. The study mainly consists
of two components i.e., hazard assessment and crises/disaster management plan. Hazard
assessment study includes:
   •   Identification of location, storage and handling of hazardous chemicals in the Port area.
   •   Review of possibility and sources of the loss from containment of the chemicals,
       Maximum Credible Accident analysis and their consequences.
   •   Plotting vulnerable zones and for each hazardous chemical by indicating time of
       affliction and the cloud movement of toxic dispersion.
   •   Preparation and updating of Crises/DMP management plan.

        Visakhapatnam Port Trust has inner harbour and outer harbour with 19 and 8 berths
respectively. VPT is mainly handling hazardous substances like LPG, Liquid ammonia, Crude,
Naptha, MS/ATF, SKO, Diesel, Fuel oils, Styrene monomer, Molten sulphur, Alumina, Caustic
soda, Phosphoric acid, Sulphuric acid etc. The classification of hazard chemicals are rated on the
basis of National Fire Protection Agency, International Marine Dangerous Goods (IMDG),
Marine Pollution (MARPOL73/78) and discussed for the purpose of planning for emergencies.

        Maximum Credible Accident (MCA) analysis was made for navigation, berthing,
loading, unloading, handling, transfer by pipe lines and storages within VPT and outside Port
area. The details of hazard assessment studies depicted as Risk contours for Pool Fire, Fire-
explosion and Toxic dispersion and corresponding Disaster Management Plan included in the
report.

Disaster Management Plan

        Based on the hazard assessment study, the Crises/ Disaster management plan has
delineated for identified vulnerable areas which are divided into 16 response zones of the Port.
Each response zone is spread over a large area and the emergency response required is of
specific nature. The plan highlights, an active role of Port users for a collective emergency
response in co-ordination with VPT. The responsibilities assigned for each hazard are based on
the type of installations. Thus, the emergency response system has to coordinate VPT personnel,
Port users and offsite agencies. The typical action plan is outlined for dealing with emergencies
due to LPG accident in the Port. Further measures needed for emergency response for all
identified MCA scenarios i.e., flammable/combustible liquids ammonia toxic cloud and
oil/chemical spills are also described. In order to avoid or mitigate the effect of such situations,
following are mainly considered for evolving pragmatic DMP for VPT operations:
   • Minimize the occurrence of catastrophic events
   • Prevent injury, loss of life or damages,
   • Activate and ensure involvement of all personnel and agencies in emergency response and
   • Alert the affected personnel and community by warning through communication and other
     remedial measures.

    Specific suggestions are made to update DMP whenever the new activities are undertaken by
VPT. Further emergency action plans of various Port users involving hazardous cargos need to
be integrated into the Crises/Disaster Management Plan for execution as joint action plans as it
would facilitate better coordination, and emergency operations.
