International sewage discharge is regulated under the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex IV, yet not all wastewater is treated equally.
While discharge of black water is regulated, grey water is not. To understand the legislation, there is a need to differentiate between black water and grey water.
What is black water?
While black water lacks an official regulatory definition, it is commonly understood to correspond with MARPOL’s definition of sewage. It includes drainage and waste from toilets, urinals, medical facilities, and areas housing animals. In its untreated state, black water may contain harmful bacteria, viruses, and other substances that can negatively affect marine ecosystems.
A guidance on the safe transport of project and break-bulk cargoes, outlining essential measures to mitigate risks associated such shipments.
Break bulk cargo consists of individually loaded goods that are not in shipping containers, typically packed in drums, bags, pallets, barrels, or crates. Examples include machinery parts, steel coils, or coffee bags. Project cargo involves large, heavy, or oversized items that need specialized handling and transport due to their size, weight, or complexity. Project cargo includes items like wind turbine components, oversized pipes, or heavy machinery. They demand special attention throughout loading, stowage, securing, transport, and discharge.
While generally safe for sea transport, these cargoes need thorough planning and risk assessment to prevent shifting or accidents during the voyage. In its guidance, Steamship Mutual has included the following key points for the safe transport of project and break-bulk cargoes:

This circular is to draw attention to incidents of concern regarding shipments of coal from North-East Coast USA.
Incidents have involved explosions resulting in the displacement/removal of hatch covers.
The US Coast Guard issued a Marine Safety Alert in February 2025 highlighting some of the issues.
The issues are complex, and incidents remain under investigation.
This circular is not therefore intended to provide views or guidance on issues arising in the USCG alert.
