Stena Line is 10 Years Ahead of IMO Emissions Goals

Ferry shipping company Stena Line reports it is 10 years ahead of international shipping's emissions reduction targets thanks to measures such as new, larger and more energy efficient vessels, AI assisted captains and an increased punctuality.The Sweden-based operator says that during 2019 it reduced its total CO2 emissions 1.7 %, corresponding to 24,000 metric tons of CO2 in total, while CO2 emissions per transported ton freight and passenger vehicles on board the vessels fell…

Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency

It is easy to appreciate why permanent magnet synchronous motors (PMSMs) are popular for use in underwater vehicles (UVs). They are compact and efficient with a high power density. More importantly, perhaps, they allow for effective operation across a broad RPM range which is beneficial for vehicles with multiple operating conditions. That said, we find vehicle product developers are often uncertain about a motor’s “efficiency”. This article offers a few comments from the perspective of a propeller designer…

EPA Tier 4: Difficult and Contentious, 12 Years and Counting

When it comes to complying with EPA’s Tier 4 emissions regulations, there’s no shortage of creativity emerging from America’s maritime engineering firms. Companies such as Hug Engineering are offering flexible, customized aftertreatment-based control systems that can assemble almost in modular like fashion. Other companies, such as ABB Group, offer battery-hybrid power sources to complement combustion power and avoid threshold diesel emissions. Engine manufacturers, such as Cummins…

Rewrite the Rules: The Path to Zero Emissions

With social media updates and conference agendas addressing the subjects of climate change, emissions reductions and alternative fuels, it’s a wonder we are not climbing the Himalayans in search of the Jedi Master that will provide us with the magic potion. Yoda’s blessing with a calming breath, “You have chosen wisely.”Government emissions intervention started with a move to reduce energy and fuel consumption measured in greenhouse gas (GHG), at a time when the world and our politicians spoke about global warming.

Want to Cut Emissions? SLOW DOWN

Merchant ships traditionally operate in the open sea at or near full speed. This is hard on the engine, hard on the ship and hard on the crew. Slowing down reduces wear on the engine, improves fuel efficiency, reduces harmful air emissions and improves safety by providing the bridge personnel additional time to evaluate developing situations. Some marine engines, though, are designed to operate at near full load. Thus, for these engines, slow steaming creates its own set of problems – not insurmountable…

Maritime 2050: Facing the Decarbonization Challenge

The International Maritime Organization (IMO) greenhouse gas (GHG) strategy signals a true game changing moment for the shipping industry. External pressure was building, but the IMO strategy sets a time line and goals for shipping to tackle one of the great challenges of our time. The GHG strategy gives our latest Maritime Forecast to 2050 its focus, and with this publication we attempt to set out the different strategies and pathways the industry can take to reach these goals.The first conclusion from the report is a sobering one.
