Maritime Switchboards

Extreme conditions require safe, seamless electricity distribution in maritime switchboards.

Elpro is an experienced and flexible supplier of maritime switchboards and maritime switchboard solutions for sea borne vessels and off- and onshore structures. We design and build advanced, modern switchboards for all types of maritime vessels, and guarantee maximum utilisation and management of all electrical power on board. Elpro has continuously developed our own switchboard design for over thirty years.

Future proof maritime switchboards

To meet the wide range of functional and technical requirements in the market, we customise and supply future proof and installation-friendly solutions with market leading customer satisfaction. All our maritime switchboards are manufactured at the Elpro factory in Selva, Norway.

Talk to us about your project

From hull to seagoing ship – we manage the entire project from the birth of the project to its launch. If the ship is built abroad, final fitting can be completed at our ship yard facilities in Fosen Norway.

Features

Closed ring system that satisﬁes the highest DP requirements.
Directional protection and zone selectivity, which allows minimum loss of bus bar sections even for a worst-case single fault on a vessel with ERN 4×99, running with closed bus ties.
Power Management System (PMS) can be included in the switchboard (which saves yard for a lot of cabling and potential fault ﬁnding in the future).
Load Sharing (LS) can be included in the switchboard without taking any extra space on each generator cubicle (symmetric, ﬁxed power, asymmetric).
AVR’s can be mounted in each generator cubicle for easier fault ﬁnding and commissioning.
Ultra Rapid breaker (UR breaker) can be mounted into our switchboard to allow higher installed power running in parallel @690V, and to limit the short circuit level to 100kA/220kA peak.
Calculations, production and commissioning.
Robust chassis – we are extremely flexible, and can build according to special dimensions and specific requirements. That means robust solutions able to cope with vibrations and any tough environment.
Norwegian-made, with top-quality design: We have extensive experience, a factor that minimises risk for the end-customer.
Painting: Our factory has a large-scale and highly-advanced powder coating facility to provide switchboards with a unique appearance and colour scheme.
FAT can be performed at our factory.
Elpro can handle commissioning and installation of switchboards prior to delivery.
Switches and components: Elpro use qualified and experienced partners.
Commissioning is performed on aboard the vessel where it is being built, and we can work anywhere in the world.

Services

Speciﬁcation in close cooperation with client and systems integrator.
Project management from A to Z. Single point of contact for clients.
Engineering and design for marine purposes compliant with the requirements of the vessels class requirements.
Construction and manufacturing: Produced in 2mm cold-rolled steel and in accordance with IEC 61439-2. Flexible solutions are possible due to in-house construction of all steel parts.
Surface treatment: All parts are treated and powder coated at our paint department with a selection of RAL colours.
Documentation is produced with state of the art design soﬅware, and customer prior to production approves the plot plan. Short circuit calculations are in accordance with IEC EN 61439.
Copper rails and bus bars are critical equipment and must be able to cope with high voltage. We make bus bars at our own factory, where we bend and customise before installation. We save bus bar shapes as 3D drawings to make it easy to retrieve them in the future.
If anything should ever happen to the main- or back-up switchboards, the ship can lose propulsion. In such a situation, when new rails or bus bars are needed, fast reaction is needed to get them out to the ship.
