A cool ECDIS is a compliant ECDIS. Do not let dust and heat put your vessel at risk.
If cleaning doesn't work, consider these long-term fixes:
The marine environment is inherently dusty. Salt air and micro-particulates get drawn into the ECDIS chassis via cooling fans, clogging the heat sinks.
: Supports both Vector (ENC) and Raster (RNC) navigational charts, essential for meeting SOLAS chart carriage requirements.

The Navi-Sailor 4000 runs on dedicated marine-grade computers, which process large amounts of data. The primary hardware components—the CPU and the graphics card—generate significant heat, which must be dissipated by internal fans and heat sinks.
If the vessel carries a qualified electro-technical officer (ETO) and standard maintenance spares are available: Open the chassis cover of the marine PC.

Operating a vessel with a known issue is a direct violation of SOLAS Chapter V, Regulation 18 (Approval, surveys, and performance standards). If the unit shuts down mid-passage and you have no backup, your vessel fails the Passage Planning requirement under the ISM Code.
Trusted by mariners worldwide, the Transas Navi-Sailor 4000 ECDIS remains a heavyweight in the world of electronic navigation. Even as we see the transition to the newer Navi-Sailor 5100 series, the 4000 is still the "heart of the wheelhouse" on thousands of vessels.
For modern navigational officers seeking a system that is "hot" — meaning highly desirable, technically impressive, reliable under pressure, and equipped with the most sought-after capabilities — the Navi-Sailor 4000 delivers on all fronts. This article explores why this ECDIS model remains an indispensable asset for ship owners and a trusted companion for officers on watch (OOW).
The Navi-Sailor 4000 ECDIS is more than just a digital chart display; it is a comprehensive navigation decision support system. Developed by Wärtsilä (formerly Transas), this system is designed to comply with the latest IMO, IHO, and IEC standards. Its primary function is to contribute to safe navigation by providing the bridge team with real-time positioning, sensor integration, and advanced route planning tools. The "hot" status of this equipment stems from its seamless integration of hardware and software, making it a favorite for both newbuilds and retrofits.
Ignoring a hot processing unit is dangerous. Here are the warning signs specific to the Navi Sailor 4000:
Suddenly, the screen hissed. A horizontal line of static tore through the center of the display, and the "hot" warning turned into a final, scrolling command: SHUTDOWN IMMINENT
