◆ GRE PIPING SYSTEM（Glass-fiber Reinforced Epoxy piping system） GRE Pipe layout and Engineering – FPI GRE Pipe sales and installation agent in Japan Applications: EGCS/SOx scrubber drainage and water supply pipes, DBTM ballast water transfer pipes, offshore wind turbine drainage pipes, TLP ballast water transfer pipes, fire extinguishing piping, bilge piping, cooling water and Fresh water piping, inert gas piping, drinking water, deck cleaning piping, etc. ◆ GRE for DBTM Ballast Line piping system（FIBERMAR™） The overall piping system design, combined with the adoption of GRE couplers/mechanical joints (Rubber Seal Joints: ClassNK type approval TA21349M), allows the couplers to move axially by ±50 mm and accommodate deflection angles up to 1.5 degrees. This provides tolerance (allowable range) for the installation of adjacent pipe materials and offers sufficient flexibility to the pipe system, allowing it to follow the vertical deformation (sagging and hogging) of the hull that occurs during navigation. ◆GRE SLEEVE solution（for EGCS drainage Distance Piece）＋Grout application, corrosion prevention Grout application to hull plating

Electronic Inclinometer
◆DANIAMANT Electronic Inclinometer Equipment Overview： ・The IMO mandated the installation of “electronic inclinometers” on container ships and bulk carriers with a gross tonnage of 3,000 tons or more built on or after January 1, 2026. ・Measures the ship’s roll angle and roll period and displays them on the bridge. ・Performance standards have been established for devices that record data in the Navigation Data Recorder (VDR). Background and Purpose of Installation： Purpose of Installation： ・To provide information on the ship’s inclination to the captain and other operators. ・To support appropriate decision-making regarding navigation. ・To understand the ship’s inclination in the event of a maritime accident and use this information for accident investigation and analysis. Performance Standards： Compliant with MSC.363(92), ISO 19697:2025, IEC 61162-1 & 2, and IEC 61162-450 interface. BOSMEC is the Japanese distributor for Daniamant, a Danish company. Certifications: MED/DNV certified, BSH type approval obtained, JG application pending. Detection Principle: Based on state-of-the-art MEMS (Micro Electro Mechanical Systems) technology, the sensor unit incorporates a high-precision 6-degree-of-freedom MEMS sensor (3-axis accelerometer + 3-axis gyroscope) as a motion sensing element. The sensor does not require periodic calibration. Display Unit Installation Location: Recommended location is within the navigation bridge. It features a bidirectional interface for transmitting alarms from the electronic inclinometer to an external system (BAM/INS) and for confirming and silencing warnings from the external system. Sensor Unit Installation Requirements: Mount the sensor unit horizontally, aligned with the ship’s axis (it does not need to be mounted on the ship’s centerline). The sensor unit measures tilt angle, pitch angle, turning speed, and acceleration in real time, and transmits the data to a VDR or similar device via an RS-422/485 serial interface. Tilt angle and pitch angle data are calculated using raw data from both the accelerometer and gyroscope, employing advanced sensor fusion and…

Maritime Cybersecurity
– Maritime Cybersecurity – Maritime Cybersecurity Our affiliate, Athena Dynamics Pte Ltd (ADPL) in Singapore, has organized a global specialized IT team (GHA/gha: Good Hackers Alliance) that can comprehensively implement cybersecurity measures for onboard network systems, from Identification → Defense → Detection → Response → Recovery, using remote access via satellite communication. ■Specific Cyberattack Methods • Ransomware hijacking of ship management systems • GPS spoofing to falsify location information (a type of cyberattack that misleads GPS location information by transmitting false GPS signals, disrupting ship routes or causing collisions) • Theft of crew members’ personal information through phishing scams, etc. Based on reported cases to date, the following onboard systems are the main targets of cyberattacks. ➣ IT (Information Technology) systems such as PCs for office work on ships ➣ OT (Operation Technology) systems such as navigation equipment, engine control devices, and cargo monitoring devices We can remotely access and conduct Asset Discovery (asset survey) of vessels operated by ship management companies, in accordance with the IMO-mandated cybersecurity standard UR E26. Furthermore, if you install cloud-based software (XDR agent) on the ship’s network from land, our Security Operation Center (SOC) can provide full support, from implementation to operation, maintenance, and 24/7/365 continuous monitoring. There are two mandatory IACS requirements applicable to vessels whose construction contracts are signed on or after July 1, 2024 (for newly built vessels): UR E26 “Cyber Resilience of Ships” UR E27 “Cyber Resilience of Onboard Systems and Equipment” – For newly built ships – – For Existing Vessels – The mandatory requirements of IACS UR E26/27 mentioned above do not apply to existing vessels. However, since cyber risks are the same, cybersecurity measures for the onboard network are necessary. As a countermeasure, we propose a straightforward modification of the onboard network using the following procedure (3…

Hull Stress Monitoring System – Installation and Commissioning
◆Hull Stress Monitoring System (HSM) Installation, Commissioning & Maintenance Services Operating vessels safely and cost-effectively requires accurate knowledge of ship design and an understanding of operational risks and their impacts. One challenge is the lack of information on actual loads on the hull at the Navigation Bridge. Previously, this problem relied on the judgment and experience of the navigator, but this technology allows for the acquisition of live data during voyages via the SENSFIB Hull™ Hull Stress Monitoring Solution. By monitoring the stress response of the hull structure during operation, it provides navigators with online information on load margins, supporting their decision-making. Features of the Hull Stress Monitoring System (HSM)： The sensor employs a Fiber Bragg Grating Sensor (FBG) for highly accurate measurements. Welding is not required for sensor installation, allowing for installation in hazardous areas. The sensors have IP68 waterproofing and can be completely waterproofed by applying epoxy resin adhesive, allowing for installation on upper decks and inside ballast tanks. By analyzing the collected data, it is possible to determine the necessity of inspections by classification societies and surveyors, reduce costs, and determine the service life. If fatigue data is obtained, it can also lead to life extension assessments, improving the durability of the vessel and aiding in the development of effective maintenance schedules and repair plans. If abnormal stress or fatigue is detected, appropriate measures can be taken to prevent accidents and damage to the vessel. We have obtained the ABS classification society’s SMART (SHM) Tier 3 Product Design Assessment (PDA) certificate. HSMs are also installed for applications such as sloshing monitoring of LNG fuel tanks and ice road monitoring on ICE-class vessels. FGB Sensors Installation Location (Based on Ship Classification Notation) 4 x FBG sensors installed on the upper deck (fully waterproofed) Typical system configuration (example)…
