Kongsberg Maritime's HiPAP (High Precision Acoustic Positioning) series is globally recognized as the benchmark for high-performance underwater positioning. From the flagship model HiPAP 501 (241 element spherical transducer) to the portable HiPAP 351P, and then to the ultra deep water HiPAP 101 (working depth of 6500 meters), this family covers various application scenarios from shallow water to full sea depth. This article is based on the technical specifications of the HiPAP system, combined with practical engineering experience, to systematically explain the installation specifications of transducers and deck units, the configuration of APOS operating system, the selection principles of SSBL/LBL positioning modes, the advantages of Cymbal broadband protocol, and the most commonly encountered fault diagnosis and troubleshooting methods on site. Whether you are a DP operator, acoustic positioning engineer, or ROV navigator, this article will be an essential technical reference for you to carry with you.
The Seatex MRU 5, owned by Kongsberg Maritime, is the third generation solid-state motion sensor designed to meet such demanding requirements. It adopts MEMS technology without mechanical rotating parts, which can provide dynamic roll/pitch accuracy of 0.03 ° RMS level, heave accuracy of 5cm or 5% (whichever is larger), and support data output rate up to 100Hz. This article is based on the official technical specifications of MRU 5, combined with years of shipborne integration experience, to systematically explain the installation specifications, communication interface configuration, output variable selection, connection methods with third-party devices (such as multibeam sonar and DP systems), as well as the most commonly encountered fault diagnosis and troubleshooting processes of the sensor. Whether you are a ship electronics engineer, hydrological surveyor, or DP operator, this article will provide you with technical knowledge that can be directly used for on-site operations.
In modern ship bridge management, ensuring that the bridge is always manned is a key step in preventing accidents such as collisions and grounding. The International Maritime Organization (IMO) has clarified the performance standards for Bridge Navigation Duty Alarm Systems (BNWAS) through MSC. 128 (75) resolution, particularly for vessels operating on a single bridge, which must have reliable activity monitoring and alarm transfer capabilities. The Bridge Watch Monitoring System (BWMS) launched by Kongsberg Maritime is a professional solution that meets this requirement.
The automation level of modern ships is increasing day by day, and engineers need to monitor hundreds of parameters such as main engine, auxiliary engine, pump set, liquid level, temperature, pressure, etc. in real time. All of this relies on a reliable control unit - WCU (Ship Control Unit). Although WCU, as the core component of K-Chief and other integrated monitoring and alarm systems (IAS), is usually designed to be maintenance free and have a long lifespan, it still encounters problems such as communication interruptions, power failures, and abnormal input signals on site. This article is based on the official technical specifications of the WCU module, combined with years of experience in marine automation engineering, to provide a systematic guide on the hardware installation, electrical connections, environmental adaptability, certification requirements, and common faults of WCU, helping ship engineers and crew members quickly locate problems and restore the system.
