MSK helps businesses ensure compliance with environment testing regulations for maritime trade

Maritime Trade Regulation Compliance Ensured with MSK’s Environment Testing Capability 

Around 90% of traded goods are carried over the waves. As such, the oceans provide the main transport arteries for global trade. Pollution emissions from international vessels have a significant impact on public health and global climate changes. In addition, shipping companies have also emphasized environmental policy for the purpose of achieving corporate social responsibility and eco-efficiency. MSK marine services help your business comply with shipping regulations. As the maritime industry becomes increasingly regulated, it is vital your business ensures its ships and cargo are compliant with relevant regulations and are safe for stakeholders and the environment.

Air Environment

Expected growth in ship traffic will add significantly to local air quality problems and global climate-change risks unless ship emissions are further controlled. During the burning process in marine diesel engines, boilers, and incinerators, these fuels can produce significant amounts of black smoke, particulate matter (PM), nitrogen oxides (NOx), un-burned hydrocarbons (UHC), sulfur oxides (SOx), carbon monoxide (CO), carbon dioxide (CO2), etc. Table 1.1. IMO (2000) estimated CO2, NOx, and SOx emission, which were based on an estimate of marine bunker fuel consumption and a statistical model, found that ocean-going vessels accounted for about 1.8 percent of global CO2 emissions.

Noise Environment

Long-term exposure to noise can cause a variety of health effects including annoyance, sleep disturbance, negative effects on the cardiovascular and metabolic system. On the vessel any machinery activities induce noise level in the ambient environment e.g. shipyard movement, moving machinery, engine room, compressors, welding machine, small generators and other activities. The monitoring on the vessel deck is done as per IFC EHS General Guidelines, 2007(Table 1.2) which details are as follows:

Water Environment

Water safety and quality are fundamental to crew members and passengers onboard. Considering that water storage and distribution systems on ships are complex and could provide conditions for bacterial contamination, potable water on ships must be obtained only from those water sources and water supplies that provide potable water and are approved by WHO 2008, ISO 10500 and other national and international standards.

Sewage pollution control was the first environmental initiative in history. Technologies and regulations for land-based wastewater industries have been evolving for more than a century, bringing tangible improvements to our aqua environment. The IMO’s MARPOL Annex IV Convention, which aims at achieving the prevention of pollution by sewage from ships, was developed in the 1970s, and entered into force since 2003, EPA, 2002, and MECP. 227.(64), 2012.
