E-WERF designs and installs on-board electrical systems fully tailored to the vessel and the existing on-board network. We realise complete systems including additional battery capacity, 230V inverters, lighting, navigation and communication systems and bow thruster installations. All components are carefully integrated so that new equipment interacts smoothly with existing systems. A well-designed installation increases both reliability and comfort on board: silent and emission-free sailing, sufficient power for all facilities and minimal maintenance. E-WERF works with high-quality materials and A-brand components, and applies smart monitoring via displays or apps whenever possible. This keeps you informed of battery status, consumption and charge level at all times. All installations are carried out according to the applicable maritime safety standards and feature protection against overload, short-circuits and leakage currents.

Has your boat's electrical system become outdated or cluttered? E-WERF puts the system back in order and makes it ready for the future. We redesign wiring and components according to current standards and deliver a clear, safe installation with full documentation. This keeps maintenance simple and you always know exactly how the system is set up.

A much-requested upgrade is the switch from lead-acid batteries to lithium systems. These offer more power, longer life and significantly less weight. We not only replace batteries, but also ensure that charging equipment, security and control are optimally tuned. Our engineers integrate smart chargers, inverters and battery management systems, making the on-board network more efficient and low-maintenance.

E-WERF always delivers customised solutions - from small sloops to luxury sailing yachts. Together, we determine the sailing profile, energy requirements and budget. We can integrate additional solar panels or design hybrid solutions where a generator serves as a back-up. With a transparent working method and a clear quotation in advance, you know exactly where you stand.

Many commercial vessels are still equipped with traditional diesel generators, outdated electrical technology or inefficient battery banks. E-WERF modernises these vessels with the latest marine energy systems. For those wishing to switch to electric or hybrid propulsion, we take care of the complete conversion: from technical design and installation of electric motors to the integration of battery packs and existing on-board systems. Each project is tailor-made, in consultation with the owner or operator, so that the system fits the business operations in the best possible way. Individual subsystems can also be renewed, such as inverter/charger systems, shore power connections with protection or PLC automation for the onboard installation. Navigation and communication systems, including radar, AIS and VHF radio, are reliably powered and carefully integrated by us. For refits, we critically assess existing schematics and make improvements where necessary. The result is an orderly, future-proof installation with up-to-date documentation and clear drawings.

E-WERF works according to the ES-TRIN guidelines for inland navigation and the applicable NEN 1010/3140 standards. If required, we build according to class requirements so that the installation is immediately ready for inspection and certification. As periodic inspections are often mandatory in commercial shipping, our working method is fully geared to this. Every step is carefully recorded and provided with clear diagrams, so that you always have insight into the technical condition of your ship. We only use components that comply with maritime standards and ensure vibration-proof assembly, watertight connections and corrosion protection. Before delivery, each installation is extensively tested. Safety and operational reliability are key: your ship must continue to operate reliably, without unexpected downtime.

After delivery, E-WERF remains actively involved with the vessel. In commercial shipping, preventive maintenance is essential to avoid downtime and unnecessary costs. We provide service and maintenance services for electric and hybrid-powered vessels, including workboats, emergency services and passenger ships. During periodic inspections, we check all critical components, replace wear parts in time and calibrate systems for optimal performance. In case of malfunctions, our engineers are on standby immediately; often the same day in the Amsterdam region. Thanks to modern monitoring, systems can be followed remotely and deviations detected early, thus preventing malfunctions. If required, we supply redundant systems and spare parts to safeguard essential functions on board. Our working method is transparent: clear agreements, insightful reports and realistic planning ensure continuity and trust.

E-WERF has extensive experience in professional shipping and has successfully completed many projects. We supplied electric drives for workboats and canal boats and support shipping companies and governments in making their fleets more sustainable. Our approach combines craftsmanship with customisation: first a careful inventory, then a clear proposal and implementation according to a tight schedule. During commissioning, all systems are extensively tested, often culminating in a trial run. Thanks to cooperation with leading suppliers, we offer reliable, certified solutions such as heavy-duty lithium batteries and advanced energy management systems. Whether it is an intervention boat, measurement vessel or passenger ship, E-WERF provides an electrical installation that suits the vessel's function and use. Innovation, precision and sustainability form the basis of our work - aimed at future-proof, all-electric shipping.
