On board electrical reliability is a key issue due to the remoteness of vessels and platforms. It is especially critical in maritime environments where service personnel and repair equipment may be several days away. For this reason, safety is of paramount importance. Cost is another important factor taken into consideration in vessel design, and designers optimize with all of the above in mind.
Vessels often utilize different methods of system grounding. Whether solidly grounded, resistance grounded, or ungrounded, all systems have their pros and cons, which have to be considered carefully while designing the vessel.
Learn more about the safety solutions offered in this webinar hosted by two of Bender's industry experts!
Key Topics Covered
Basic design power distribution system of vessels
Differences between solidly grounded, high resistance and ungrounded system and preferences according voltage level
Ground fault detection and location and sensitivity within the different systems and effects for system availability (system cost vs. vessel cost)
Stray currents within the system types
Offline monitoring of consumers
Umbilical monitoring and shore power connections
Maritime Segment Manager & Business Development (Germany)
Benjamin holds both a bachelor's and master's degree in electrical engineering. Since 2006 he has worked on shipyards in electrical engineering and project management for mega yachts and naval vessels. He was responsible for the electrical system of a 95-meter new build, and later, an onboard warranty engineer of a 150+ meter yacht. Since 2016, he has been responsible for maritime applications at Bender where he helps customers find insulation faults and stray currents on board maritime applications without time-consuming shutdowns.
