Interview: John Batten, CEO, Twin Disc
How have major events such as the U.S./China trade war, oil price fall and COVID-19 impacted Twin Disc’s commercial marine business to date, and what adjustments have you made in response?These are the three things that I’ve been highlighting in employee communications and with investors over the last few months. For us, COVID was just the third punch after the other two. China is typically our second largest market after the U.S., and we lost lots of orders to our competitors as the trade war started to affect us. It’s rebounding a little, but it definitely impacted our sales into China.

Will Customers Redefine Design and the Science of Marine Propulsion?
It is “pre-COVID ” April of 2018, and 174 member states of IMO adopt a new strategy to reduce greenhouse gases from shipping. The meetings are considered “urgent” and the target is to reduce carbon emissions in half by 2050. Prior to those “targets” shipping dealt with regulations to address SOx and NOx reductions. Most of which have resulted in limited success due to infrastructure problems and a consideration as a temporary fix.The technical world has responded with low sulfur fuels, LNG, and methanol to work towards the target.
