Ocean-going vessels are often viewed as major contributors to air pollution. This is particularly important in port communities where vessel engines generate air pollution at berth. Matson’s vessel engineering and operations departments have been focused on reducing air pollutant emissions for many years. Their philosophy is to go beyond compliance in virtually all of their business activities.
An Unfamiliar Request
Matson tasked Glosten to develop cold ironing solutions for eight of their vessels. Cold ironing, also known as alternative marine power (AMP), involves completely shutting down vessel engines and generators in port and connecting to shore based electrical power. Instead of running diesel engines at berth, ships use shore power to run lights, ventilation, communications, pumps, and other vessel systems. This concept of using a dockside electrical infrastructure to power large ships while in port was brand new at the time and nowhere near as simple as it sounds.
We Love a Challenge
Glosten engineers conducted some very innovative engineering work, collaborating with the ships’ crew to determine power requirements and develop an installation approach to minimize impacts to vessel operations. There was no standard in place when Glosten and Matson began this project. Early involvement with regulators and classification societies was essential to ensure equipment and installation practice approval, and allowed ongoing improvements to our project. Cooperative design efforts with the ports ensured compatibility between the ship and shore instrumentation, monitoring, and alarms.
Cleaner and Greener Ships
Matson now “plugs in” at Port of Long Beach and Oakland and has cut air pollution from their ships at berth by 100 percent. Matson sets a high bar when it comes to environmental stewardship.
