Berthing Approach System(BAS)

The Berthing Approach System (BAS) is used for safe berthing of vessels by measuring the distance, speed and angle of the ship’s bow and stern section in relation to the berth fenders and triggers alarms during the final sideways berthing phase. The BAS comprise the systems to determine a vessels bow and stern approach velocity and display this information on an LED Display, handheld pagers and within the Shore Control Centre. ► The BAS consist of the following components:   ◎ 2 No. lasers   ◎  1 No. large Numeric LED Display   ◎ 2 No. handheld Pagers ► Lasers The lasers shall have the following minimum specifications as listed in Table 9. Criteria Design value Laser Range 0 to 300 [m]. Measuring Distance Accuracy ± 2 [mm] at 0 – 300 [m] Computer Display Distance Resolution ± 1 [mm] at 0 – 300 [m] Large Display Distance Resolution ± 0.5 [m] at 0 – 300 [m] Velocity Range 0 – 99 [cm/s] Measuring Velocity Accuracy ± 0...
