They must be used during bunkering operations
Scuppers must be plugged during bunkering operations to prevent marine pollution. The International Convention for the Prevention of Pollution from Ships (MARPOL) requires the mandatory plugging of deck scuppers during bunkering operations, cargo transfers, and oil/chemical transfers. This regulation ensures that any spilled substances remain contained on the deck, preventing them from reaching the ocean.
Bunkering operations involve the transfer of fuel, diesel oil, sludge, cargo, or lube oil to another ship for use in its machinery. These operations are considered dangerous due to the risk of fire accidents or oil spills. Before initiating bunkering, it is crucial to calculate and determine which bunker oil tanks need to be filled, emptied, or require oil transfers to prevent mixing incompatible oils. Additionally, the sounding of other fuel storage tanks is essential to monitor fuel levels and identify any potential leaks.
To ensure a safe bunkering process, a meeting should be conducted among the participating members to establish clear procedures. This includes determining which tanks will be filled, the sequence of filling, the amount of bunker oil required, safety protocols, and emergency responses in case of an oil spill. Scupper plugs play a vital role in environmental compliance during bunkering operations. By plugging the deck drainage openings, scuppers contain potential spills on the deck, preventing pollutants from entering the ocean.
The use of scupper plugs during bunkering operations is a critical strategy for environmental protection. These plugs are designed to seal deck scuppers, preventing unwanted fluids from entering or exiting the vessel. They serve as a frontline defence against marine pollution, ensuring that any spilled oil or chemicals remain contained. Scupper plugs also aid in water control, preventing seawater from entering the vessel during rough weather conditions or specific operations.
The proper use of scupper plugs during bunkering is essential for compliance with international regulations and local port requirements. Vessels are subject to inspections to verify the adequate supply and functionality of scupper plugs. Failing to use scuppers properly can result in costly pollution incidents, substantial fines, and extensive cleanup operations. Therefore, scuppers must be plugged during bunkering operations to mitigate environmental risks and adhere to pollution regulations.

Also during cargo transfers involving oil or chemicals
During cargo transfers involving oil or chemicals, pollution regulations require that deck scuppers be plugged before operations begin. This is to ensure that any spills are contained on the deck and do not reach the ocean. The International Convention for the Prevention of Pollution from Ships (MARPOL) establishes strict requirements for pollution prevention, which include the mandatory plugging of deck scuppers during such operations. Vessels must maintain a sufficient supply of properly sized and functional scupper plugs as part of their environmental protection equipment.
The use of scupper plugs is also mandated by local port state requirements for pollution prevention and vessel-specific Shipboard Oil Pollution Emergency Plans (SOPEP). Every vessel's SOPEP must include procedures for deploying scupper plugs during oil transfer operations, as well as their location, inventory, and integration into the overall spill response strategy. Failure to use scupper plugs properly can result in costly pollution incidents, substantial fines, and extensive cleanup operations.
In addition to the use of scupper plugs, there are several other regulations in place to prevent pollution during cargo transfers involving oil or chemicals. For example, oil tankers and offshore oil barges of a certain size must carry appropriate equipment and supplies for the containment and removal of on-deck oil cargo spills. These must be ready for immediate use during cargo transfer operations. Additionally, the operator or agent of the vessel must verify that each PIC (person in charge) of the transfer has sufficient training and experience with the relevant characteristics of the vessel, including the cargo for transfer, the cargo-containment system, and the shipboard emergency equipment and procedures.
Furthermore, regulations such as SOLAS Chapter VII and MARPOL Annex II set out standards for the safe carriage of dangerous goods and noxious liquid substances in bulk. The International Bulk Chemical Code (IBC Code) identifies the ship type required to carry specific products and prescribes the environmental hazard rating. The IBC Code also identifies the equipment to be carried to minimize risks to the ship, its crew, and the environment.
