1 This guideline applies to marine hydraulic devices intended for installation onboard sea-going ships classed with CCS.
2 The hydraulic power devices referred to in This Guideline include:
(1) hydraulic power devices;
(2) hydraulic automatic control devices;
(3) hydraulic remote control devices.
1.3 This Guideline does not cover:
(1) hydraulic actuating units/parts of hydraulic power devices, such as hydraulic cylinders, hydraulic motors and remote control valves;
(2) start-up and control devices (including frequency controllers) of pump-driving power units (such as electric motors);
(3) associated electrical operating and control devices (such as electrical control devices of servo valves and proportional valves);
(4) monitoring, indication and alarm systems/devices.
The above parts and devices associated with hydraulic power devices are to be certified in compliance with the requirements of Chapter 3, PART ONE of CCS Rules for Classification of Sea-going Steel Ships.
4 This Guideline refers only to the relevant requirements clearly specified for hydraulic power units and control devices in the International Convention for the Safety of Life at Sea, 1974 (hereinafter referred to as “SOLAS”) and CCS Rules for Classification of Sea-going Steel Ships, not covering requirements which are not clearly specified therein for “hydraulic” means.
5 Although the relevant requirements for hydraulic power units and control devices of certain specific equipment and systems are not specified clearly or perfectly in SOLAS and CCS Rules for Classification of Sea-going Steel Ships, the configuration, function, capacity, protection, inspection and test of such equipment and systems, if fitted with hydraulic power units and control devices, are to comply with the equivalent technical requirements for non-hydraulic power units and control devices of corresponding equipment and systems in addition to the general requirements for hydraulic power devices in This Guideline, due to the rapid development of science and technology and the continuous development and improvement of hydraulic control techniques.
6 In respect to specific requirements for steering gear hydraulic power systems, reference is to be made to certain general requirements of This Guideline and in addition, to the relevant requirements in Section 1, Chapter 13, PART THREE of CCS Rules for Classification of Sea-going Steel Ships and in Chapter 1, PART SEVEN of the Guidelines.
7 In respect to requirements for windlass hydraulic power systems, reference is to be made to certain general requirements of this Chapter and in addition, to the relevant requirements in Section 2, Chapter 13, PART THREE of CCS Rules for Classification of Sea-going Steel Ships and in Chapter 2, PART SEVEN of the Guidelines.
