At The Motorship Propulsion & Emissions Conference in May, Ricardo UK presented a tool for evaluating how a multi-engine diesel electric vessel’s reliability could be boosted by advanced engine control, with or…

Geislinger’s new Silenco acoustic coupling is designed to minimise the transfer of the structure-borne sound.

An often overlooked option in the ship design playbook, triple screw propulsion could offer a fuel efficient alternative to twin propeller configurations for a variety of vessels. That’s according to Oskar Levander,…

Autonomous ship projects may have unexpected results for the entire industry writes Stevie Knight

Technology’s Catch 22 is that innovation is at worst an expensive failure and at best - if it’s a success - it will be superseded writes Stevie Knight. No wonder that so…

Flettner rotors have a great deal going for them. In fact, early signs show they could prove an untapped goldmine – but getting it right will make or break those involved in…
