日本フィールド＆マリンエンジニアリング株式会社

To ensure that our clients’ emergency gas turbine power generation systems remain in optimal condition, we perform regular inspections and component replacements under manufacturer contracts. Depending on the equipment, fire protection systems may also be included. In such cases, certified personnel conduct semiannual and annual inspections in accordance with Japan’s Fire Service Act.

Our services include the inspection and maintenance of power distribution panels, simplified testing of circuit breakers, relay protection system checks, and inspection of starting and control storage batteries. We also handle bearing replacements for generators and motors, as well as inspection and replacement of electrical components such as sensors for gas engines and gas turbines.

In addition to these maintenance services, we also conduct on-site test runs and tuning for both regular and emergency power generation equipment.

With over two decades of experience in this field, we now handle more than 350 on-site projects per year. Trusted by manufacturers, we serve as a vital bridge between them and end-users, continuing our mission with dedication each day.

Most of the reefer containers we handle are second-hand units used for over ten years in maritime transport. After refurbishment, they are repurposed for land-based use—such as in factories, farms, ranches, and fishing ports—as refrigerators or freezers. Simply supply electricity, and they’re ready to use.

We also modify containers for special purposes like temperature-controlled storage or experimental use, offering proposals tailored to customer needs. In partnership with leasing and sales companies, we inspect, repair, and refurbish containers before delivery. If issues arise, we provide on-site maintenance and repairs.

With a stock of parts from major manufacturers, we can quickly respond to repair requests. Need a specific part? Feel free to contact us.

We provide end-to-end services for the design, manufacturing, and installation of onshore electrical systems and equipment on a made-to-order basis. We also handle upgrades and replacements of aging or discontinued equipment, offering alternative solutions.

From custom control panel design to on-site installation and test operation, we deliver user-focused proposals backed by our experience in plant maintenance. Even without existing documentation, our engineers conduct on-site surveys to ensure accurate support.

Our products have been installed in various plants and commercial buildings across Japan, and we’re fully equipped to handle large-scale electrical renovations.

Ships vary greatly depending on their purpose—whether cargo vessels, tugboats, or specialized ships—and each is equipped with a wide range of devices and systems.

Through partnerships with domestic and international manufacturers, we offer total support from commissioning to inspection, maintenance, repairs, and retrofitting. Since vessels operate globally without rest, we provide worldwide service to meet these demands.

With our motto “Anytime, Anywhere, Anything,” we’re committed to supporting the essential role of maritime transport around the world.

Ships are equipped with a wide range of devices and systems, all of which require regular inspection and maintenance. Among them, we mainly perform inspections and maintenance of main switchboards and engine remote control systems upon customer request.

As the saying goes, “anything with form will eventually break.” Even well-maintained equipment can experience faults due to harsh operating environments. We respond to such unexpected issues by identifying the cause and performing necessary repairs.

The trust we’ve earned wasn’t given—it’s the result of years of hands-on work, technical expertise, and sincere responses to a variety of on-site customer needs under partnerships with equipment manufacturers. On vessels in operation, we make the most of limited time to deliver the highest performance possible.

At Oi Container Terminal—the largest in Tokyo Port—we provide inspection, maintenance, and repair services for marine reefer containers. These refrigerated containers keep cargo at a stable temperature during ocean transport.

Before loading, we perform Pre-Trip Inspections (PTI), and if issues are found, we carry out necessary repairs. With over 40 years of experience, we began as an agent for Mitsubishi Heavy Industries and are now certified to handle parts from Daikin and Carrier Transicold. We’re proud to continue supporting this essential port.

We provide full-service support for the design, manufacturing, and installation of custom marine electrical systems and equipment, including wiring design and construction. We also handle upgrades and replacements of aging or discontinued systems, offering alternative solutions tailored to each vessel.

Our services include the design, production, installation, and commissioning of custom control panels, as well as proposals for replacing outdated equipment no longer supported by manufacturers. Drawing on extensive knowledge from marine equipment maintenance, we offer user-focused solutions—even in cases where existing documentation is limited, our engineers can perform on-board inspections.

We have a strong track record of installations on domestic, international, and government vessels, and our experience extends to shipyards and dockside work worldwide—enabling us to meet a wide range of customer needs.

We handle a wide range of marine instrumentation and control equipment for ship automation systems, including field instruments, pressure transmitters, control valves, compact controllers, electronic recorders, and signal converters.

Backed by proven technical expertise, we provide maintenance support to ensure reliable automation for both marine and land-based plants. We also offer sales of equipment and supply of consumable parts.

Through a maintenance and technical partnership with Ecospray Technologies Srl. (EST), we provide comprehensive services for EGCS (Exhaust Gas Cleaning Systems) installed on both newbuild and retrofitted vessels in Japan. Our offerings include commissioning, testing, after-sales maintenance, and periodic inspections to ensure optimal system performance.

By supporting the effective operation of EGCS, we contribute to reducing SOx and CO₂ emissions, as well as the removal of PM and soot—actively promoting environmental protection and supporting the goals of the SDGs.
