Hydraulics, Control- and Alarm systems 1/4

General:When hydraulic power is required, KANON Marine Loading Arms can be equipped with hydraulics drives, integrated in the loading arm construction, for all arm movements i.e. inboard/ouboard and slewing.

Hydraulic pressure for these hydraulic drives may come from one dedicated "power pack" for one loading arm or, which is more common, a "power pack" shared by more than one, up to ten loading arms with interconnecting hydraulic lines and dedicated valve blocks for each loading arm movement.

Control and operating of hydraulically powered loading arms can be done with direct lever operated valves called MANUAL HYDAULIC control, or with pushbutton/solenoid operated valves from Jetty-Console or Pendant-Box called ELECTRIC HYDRAULIC control.

Range alarm and monitoring for safe operation of marine loading arms is achieved by means of range alarm/systems. KANON offers various types of alarm systems which may be used for local operator warning, valve and/or pump switching, remote signaling and/or full automatic disconnecting of the loading arm from the ship with KANON's Emergency Release Coupling.

KANON's range alarm systems basically comprise following alarm functions:

A) Single alarm system featuring one alarm function for inboard and outboard movement and slewing movement.

B) Dual alarm system featuring two independant alarms for inboard and outboard movement as well as for slewing movement; typicaly used in combination with ERC.

C) Full range monitoring/alarm system featuring continous full range sensors allowing remote setting of alarm limits, selection of different alarm settings as well as continous full-range (remote) digital read-out on CRT-display.

Characteristics:KANON's hydraulics, control and alarm systems do include unique features and benefits such as:

•Field proven simultaneous inboard/outboard arm movement in manoeuvring mode resulting easiest and safest way of loading arm operation.

•Full auto-return comprising automatic controlled return movement of loading arm to safe rest-position after occurance of an Emergency Release action. This feature is considered far superior compared to traditional "break and lock" control system which lock the loading arm in its last position and needs operator manoeuvring in critical circumstances.

•Highest quality double acting hydraulic drives with stainless steel chromium plated piston-rods.

•Decentralized solenoid valve block concept resulting in minimum hydraulic interconnecting piping on jetty (only 1 line for each arm movement).

•Standard back-up hand pump included.

•Hydraulic drives with adjustable tamperproof overpressure regulatorspreventing excessive forces on the loading arm.

•Alternatively relay or PLC controls, dependant on system size, interlocking and remote communication requirements.

•Dedicated pendant box for remote control from shipside.

•Use of safe isolation amplifiers only; no use of traditional safety barriers and related earthing problems.

•Used of solidstate non-contact proximity range sensors.

•For hazardous area applications, low voltage intrinsic safety and explosion proof certification according Cenelec standards (other on request).

•Hydraulics in compliance with CETOP.
