Loading Arm Hydraulic Power Pack

a)The arms shall be hydraulic operated by a hydraulic power pack consisting of stainless steel reservoir, electric motor driven hydraulic pump, valves/fittings and gauges, and hydraulic pipings. All tubings on the arms shall be of stainless steel 316L and prefabricated. Tubings provided for interconnection of hydraulic units shall be of stainless steel 316L and the fitting shall be compression type.

b)The hydraulic system shall be sized to provide for full range movement of any component of the loading arm in a maximum of two (2) minutes. The total time required to move each loading arm from its parked position to the tanker's manifold flange shall not exceed five (5) minutes. The hydraulic and electric controls shall be designed to allow manual movement of the loading arms in the event of failure of the hydraulic or electrical systems. Failure of the hydraulic components in one arm shall not render the remaining arms in the bank inoperative.

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...
