Electronics News

Glosten is working with Ray Hunt Design and the Canaveral Pilots Association on a pilot/demonstration project for the design, construction and operation of an electric pilot boat. Marking a first for a pilot boat in the U.S., the vessel will feature a battery-electric propulsion system with an emergency ‘get home’ diesel engine. (Image: Glosten)

Considering an All-electric Future

One can hardly read industry news these days without seeing mention of hybrid vessels or batteries. We’ve all heard the praise and the pitfalls discussed by proponents and critics alike. This article is not intended to convince you if batteries are right for you or not. Instead, for owners wondering if batteries are feasible for their operation, the optimal vessel characteristics and operational parameters for all-electric vessels are presented and discussed.Hybrid vessels, generally defined by having both a diesel engine and batteries…

Seaspan Opts for SCHOTTEL Again

SCHOTTEL has been chosen as propulsion supplier for two new build Ro-Ro ferries under construction at Damen Shipyards Mangalia, Romania. Each of the vessels ordered by Canadian Seaspan Ferries Corporation will be propelled by two SCHOTTEL Combi Drives and two SCHOTTEL Transverse Thrusters. The new ferries will join the company’s first two hybrid vessels, “Seaspan Swift” and “Seaspan Reliant”, which were commissioned just over two years ago. Seaspan Ferries currently operates a fleet of seven ferries out of four terminals in British Columbia…

PROPULSION TECH: How to Get to Hybridization

Hybridization in the marine world is transitioning from the latest fad to a key part of vessel design and retrofits. Driven in part by a demand for increased efficiency and new waves of global legislation, hybridizing or electrifying a vessel is quickly becoming necessary for organizations. In fact, the International Maritime Organization (IMO) rules and guidelines for the marine industry call for reduced emissions globally, and some ports around the world have established ambitious…
