Electric Yacht Charging

,
Electric power entices us with its flexibility and adaptability. And that extends to our charging sources. We gain the ability to recharge our batteries from nearly any source, assuming everything works together. Discover the critical issues to combine multiple charging sources for electric propulsion.

Electric Yacht System Design

,
Going electric requires you to design a whole custom electric system for your ship. The challenge with electric systems is the interaction. The requirements for one minor component may determine key settings for the whole system. Today I cover some key settings for the electric system. After deciding these points, the complexity of shopping should simplify into a few simple paths.

Emergency Electric Propulsion

,
Designing an electric system requires more than just spinning a propeller. Much of an electric boat focuses around safety and emergency planning. This article covers several key decisions to design an electric system that delivers far more than propulsion. Instead, our electric system ensures reliable safety.

Ever Given: Maneuvering Options

,
How to maneuver a massive freighter into port? CAREFULLY. We design freighters around the scenario of open ocean passage at full speed. But each freighter needs to enter port, pass through canals, and a host of other precision maneuvers executed at a fraction of their design speed. How do massive commercial ships manage precision maneuvers every day?

Ever Given: What We Don’t Know

, , , , ,
Like everyone else, I watched the story of the Ever Given and formed my own theories about what happened. Except I was wrong. As the events unfolded, new information came out and I learned the increasing complexity of the accident. Each time, I developed a new theory, which failed with new information. Over a year later, what is the answer? Let’s review what we know and still do not know about the Ever Given incident.

Cranes on Ships: Introduction to Crane Integration

, , ,
In the marine world, we see cranes daily; they are very useful pieces of equipment. Despite their common appearance, we need to remember their potential for disaster. Cranes on ships generate new, subtle risks for lifting operations. Unless you know what to look for, the risks can go undetected. This article reviews the major dangers of cranes on ships.
