As a marine engineer focused on vessel design, I’ve watched the narrative on battery-electric and battery-hybrid vessels evolve from skepticism, to curiosity, to genuine acceptance in just a few short years. The passenger transportation sector, in particular, has been quick to embrace the concept of vessel electrification as a means of improving economics and reducing emissions. This makes sense as many ferry operations are excellent candidates for battery and hybrid-electric power due to their proximity to urban electrical grids…

Long a staple for offshore service providers, a more compact and carefully designed version of the diesel electric option is now available for inland pushboats. For budget conscious operators (and who isn’t, in this environment?), the stars may finally be aligned.For many years, electric propulsion has proven to be a viable propulsion solution for many different types of vessels. Most familiar to workboat stakeholders would be the advent of the ‘diesel electric’ offshore serve providers (OSV) that became commonplace during the offshore boom era. Those vessels operated in a different regulatory environment, with the emphasis more leaning towards operational efficiencies and fuel economy.

Diesel electric technology, as part of a comprehensive engineering design process, should be considered by the inland towboat sector. Diesel electric propulsion is not a new concept. Like azimuthing drives, its application to the inland marine market has lagged behind other areas of the marine industry. Diesel electric has gained traction in industries where fuel economy and redundancy of propulsion systems for safety is paramount. In particular, vessels like passenger ferries and offshore supply vessels have enjoyed the benefits of the diesel electric systems.

Eastern Shipbuilding’s forward-thinking inland towboat design now features CAT Tier 4 propulsion and aftertreatment. When Eastern Shipbuilding Group (ESG) introduced its cutting edge 4,000 hp Thunderbolt inland towboat designed around twin azimuthing AAA Propulsion electric V-Pod propulsion and diesel-electric technology back in 2015, the approach was collaborative, with input from operators, naval architects (Gilbert Associates, Inc. (GAI)) and propulsion OEM’s. In selecting the podded propulsion system for inclusion on the design, Eastern met with two inland owner/operators that had Z-Drive towboats, and others that didn’t. Starting as far back as 2013, listening to each and noting their concerns, it was decided that the V-Pod was the best solution.

Propulsion evolves, improves and powers forward in the inland markets. And, Z-Drive propulsion is the future. In a white paper released late in 2014 by The Shearer Group, Ed Shearer and Greg Beers outlined The Next Generation of inland vessels, what will drive design changes and the advantages of azimuthing stern drives – or ‘Z-Drives,’ for short. The authors point out that, until recently, towboats on all the inland waterways and Gulf Coast have traditionally been built using main engines connected to reduction gearboxes connected to long drive shafts passing through the towboat hull. In a nutshell, according The Shearer Group, the advantages of using z-Drives on inland towboats include decreased installation time…

Eastern Shipbuilding offers the 4,200 hp Thunderbolt inland towboat designed around twin azimuthing Verhaar Omega electric V-Pod propulsion and diesel-electric technology. The ESG approach was collaborative, with input from operators, naval architects (Gilbert Associates, Inc. (GAI)) and propulsion OEM’s (Verhaar Omega: since 2012, 19 Omega V-pods have been installed and are in service in Europe on various types of vessels). Thunderbolt will be built to ABS rules, but will not be classed.

Hybrid marine power and propulsion systems for workboats isn’t farfetched. In fact, it may be essential. In 2015, two significant developments are going to make many operators, owners and builders of professional vessels consider hybrid marine power. The new emissions laws – here and abroad – and the incentives for high technology manufacturers to invest in developing highly efficient batteries are the primary drivers. That said; dramatically reducing pollution in both water and…
