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…

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…
