Gangway Selection Guide

The main data we should consider is jetty tonnage level, tidal change, jetty plane status, price-performance ratio and other conditions. Users have to fill in the following parameter tables So we determine the scope of the gangway, basic dimensions and load data.

Cylindrical Fender

Cylindrical  Fenders  are commonly used fenders recommendedfor all type of applications to ensure a safeand linear berthing to a variety of vessels. Adequate installation is simply achieved by using chains, bars, ropes or peciallydesigned ladder brackets.

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...
