Breaking News! Shell Accident Occurs! Oil Spill!

On December 15, the Nigerian Maritime Administration and Safety Agency (NIMASA) announced that an oil spill accident occurred at Shell's oil loading terminal in the Delta region of Nigeria. The spill was caused by a ruptured oil pipeline at the Bonny terminal on Saturday, and the leaked oil has already reached the coastline.

NIMASA stated that it took prompt action and is actively monitoring the development of the spill to prevent further environmental damage. The agency also revealed that it is working closely with Shell Petroleum Development Company (SPDC) and other relevant stakeholders to assess the scope of the oil spill and discuss subsequent measures.

After the accident, Shell Petroleum Development Company immediately took emergency measures. The affected pipeline was shut down to prevent further leakage of oil, and oil booms were quickly deployed to protect surrounding communities from the spill and minimize its potential impact on residents' lives and the environment.

Two months ago, Shell had another oil pipeline leak incident in Singapore. At 5:30 AM local time on October 20, 2024, Shell’s onshore oil pipeline in Singapore leaked, causing oil pollution in the waters between Big and Small Mao Islands.

Causes of Terminal Oil Spill Accidents

Terminal oil spill accidents are serious environmental pollution incidents that pose significant threats to marine life and human health. Several factors can cause such spills. Below is a summary of the causes of terminal oil spill accidents.

Causes of Terminal Oil Spill Accidents

The causes of terminal oil spill accidents can be categorized into external factors and human errors.

External Factors:

• Ship listing: Cargo operations or ballast water operations causing the ship to list at a large angle, leading to fuel oil spilling from the tank vent.
• Ship collision: Crew members may lack experience, fail to observe properly, and fail to take effective measures to avoid collisions during accidents.
• Technical failure: One of the main causes of oil spill accidents, including aging tanker equipment, untimely maintenance, or cracking of tanks or pipelines due to rough seas.
• Design defects: Poor placement of the tank vent, too close to the deck, or insufficient capacity of the oil collecting tray.
• Improper handling of the oil spill alarm: Although the spill alarm is triggered, the crew fails to take immediate and effective action.

Human Errors:

• Failure to follow operating procedures: Crew members fail to follow the ship's fueling or oil transfer procedures or do not properly complete or use checklists.
• Negligence during fueling: Key crew members fail to monitor the liquid levels of designated tanks or other fuel compartments, or fuel too quickly, causing the system to exceed its design pressure or capacity, leading to over-pumping and air expansion in the tanks, causing oil vapor or fuel to suddenly spill from the tank vent.
• Improper maintenance and testing: Valves on fuel systems may not be properly opened due to improper maintenance or crew mishandling.
• Weak supervision: During fueling operations, the fueling station on the ship was not manned, and effective supervision was not implemented.

These factors may occur independently or as a combination of multiple causes, resulting in terminal oil spill accidents. In the face of such incidents, we must recognize their serious consequences and take appropriate measures.

Damages Caused by Oil Spills

Oil spills can cause severe damage to the marine ecosystem. When oil leaks into the ocean, it can directly poison marine life, disrupting the food chain and ecological balance. In addition, oil spills can cause significant economic losses to beaches and coastal areas. Oil pollution covers the beaches, making tourism and fishing industries unable to operate, severely impacting the local economy. Oil spills also pose health risks to humans, as inhaling petroleum fumes and toxic gases can lead to respiratory diseases and other health problems.

Response Measures

In response to terminal oil spill accidents, a series of measures should be taken to reduce the damage caused. First, prioritize preventative work, conduct a comprehensive assessment and monitoring of potential hazards, and establish emergency response plans. Second, strengthen the maintenance of equipment and facilities to ensure their proper operation and reduce oil spills caused by equipment failures. Furthermore, improve the professional skills and safety awareness of operators to avoid accidents due to human error. Finally, once an oil spill occurs, emergency plans should be activated immediately, and effective measures should be taken to control the spread of pollution, reducing its environmental and economic impact. Once an oil spill accident occurs, it not only leads to significant economic losses but may also face legal lawsuits, damaging the company’s reputation.
