Installing hull unit on retraction tank

After welding the retraction tank and allowing sufficient time for cooling, install the hull unit as follows:

1.Clean the hull unit flange, the O-ring and O-ring groove and coat them with a slight amount of grease. Place the O-ring in position on the tank flange.

2.Lay the gasket (1) on the top of the tank flange.

3.Orient the hull unit so that the bow mark (arrow) on its flange points toward the ship’s bow. Note that heading adjustment in the display unit is required if the bow mark does not face the ship’s bow.

4.For the 1200 mm transducer travel type, 11 of the 24 bolt holes on the hull unit flange have already been fitted with bolts. Insert the gasket (2) into the bolt holes of the tank flange to which these 11 bolts are fitted. Note that it is difficult to fit them after the hull unit has been placed on the tank.

5.Confirm that the O-ring and the gasket (1) are in position. Place the hull unit on the tank.

6.Coat every bolt, washer and nut with slight amount of grease to ease removal. Fit the insu- lation gasket (2) into the bolt holes of both the tank and hull unit flanges. Fasten the hull unit to the retraction tank with gasket (2), flat washers, spring washers and hex bolts. (Insulation gasket (2) and gasket (2) are used on the 1200 mm transducer travel type only.)

7.Reinforce the hull unit against vibration by extending stays to the ship’s hull from the two eye bolts at the top of the hull unit, referring to figure at the top of the next page.

CSH-24F, CSH-23F, CSH-23, CSH-24 specifications

Furuno, a leader in marine electronics, has developed a range of advanced marine radar systems known as the CSH series. The CSH-24, CSH-23, CSH-23F, and CSH-24F are particularly notable for their innovative technologies, designed to enhance navigational safety and operational efficiency for vessels of various sizes.

The CSH-24 and CSH-23 models are known for their impressive 24 GHz and 23 GHz frequency bands, offering high-resolution imagery and enhanced target detection capabilities. These radars utilize Furuno’s digital signal processing technology, which significantly improves target discrimination, even in cluttered environments. This feature is invaluable for navigational safety, especially in busy waterways or coastal areas.

One of the key highlights of the CSH series is its advanced Automatic Radar Plotting Aid (ARPA) functionality, which enables the proactive monitoring of marine traffic. With the ability to track multiple targets simultaneously, mariners can make more informed decisions, avoiding potential collisions and ensuring smoother navigation. Additionally, the systems provide enhanced Tracking History that allows users to analyze target movements over time.

The CSH-24F and CSH-23F models incorporate Furuno's cutting-edge features, including Fast Target Tracking and Target Predictive Motion, which further enhances reactive capabilities. These radars also offer an intuitive user interface, making it easy to operate and customize settings to fit specific navigational requirements. The displays are designed for readability, even under challenging lighting conditions, thanks to advanced anti-glare technologies.

Built with ruggedness in mind, the CSH series is designed to withstand harsh marine environments. The robust construction and weatherproof design ensure that the systems perform reliably, regardless of sea conditions. Moreover, these radar systems are compatible with a range of marine integration options, allowing for seamless connectivity with other onboard navigation equipment.

In summary, the Furuno CSH-24, CSH-23, CSH-23F, and CSH-24F radars embody a blend of advanced technology, robust design, and user-friendly interfaces. These systems stand out in the marine electronics market for their reliability and precision, making them an excellent choice for maritime professionals seeking enhanced safety and efficiency on the water.
