Flag State Administrations around the world rely on classification societies to verify international and national maritime safety and environmental regulations. This includes regulations set by the IMO (International Maritime Organization) and the ILO (International Labor Organization). There is an international perspective of legal regulation dealing with this matter, but the sensitive marine environment is not properly covered. Some maritime countries have put forward their own and stricter regulations to ensure more effective protection of their marine environments. The goal of the International Convention on Pollution from Ships (MARPOL) is to prevent and minimize marine pollution from ships and coastal units, both by accidental means and by routine operational means. The amendment of current legal regulations and the adoption of new regulations related to the marine environment are of particular importance in order to ensure more effective protection of the sea from increasing pollution from ship sewage, thus planning a negative impact on the marine organism, human health and the economy.
