The Covid-19 Pandemic had engulfed the whole world and Covid pandemonium touched every nook and corner of life. Trade and Commerce were worsely affected during this period. Trade and Commerce via sea route was not left untouched and hence an intro-spection into Marine Law and the insurance relating to Covid Pandemic was felt necessitated. This paper focuses on the different aspects of marine law, particularly marine insurance. Marine law is the one of the oldest types of law that govern, tort, contract, shipping, claims over shipments and like. The Cruise ships, with large numbers of passengers and crew and an emphasis on communal dining and group activities - became incubators of the Covid-19 virus, and infections on ships have been termed as floating nightmares. This has touched the trade and commerce in marine areas resulting in heavy loss in trade and commerce and hence the need to extend the applicability of insurance in trade and commerce via sea. Insurance implications arise from the disruption of shipping and logistics due to the pandemic. Delay in transit was the major disadvantaged part of the pandemic crisis. There was embargo of marine cover with respect to the delay in transit. Cargo is also envisaged to be held for a longer duration at ports and for storage locations.The impact of Covid-19 on marine insurance opens scope of different possible lacunas in policy coverages. The situations in which the policy doesn’t cover and different types of claims that is likely to arise in future also is covered in this paper. This also aims to cover the different types of marine insurance and their extension and applicability in the deadly pandemic period.
