2 Quick Release Hook 卓冠Quick Release Mooring Hook 1. GENERAL DESCRIPTION Installed at dock, Quick release hooks are special equipments for winding and tying of ships. They are the update products of mooring dolphins. Compared with cleat, they reduce working intensity, increase working efficiency and improve safety and reliability. Quick release hook consists of integrated electrical winch and release systems. They are suitable for large tonnage ships mooring harbors that require fewer workers and quick releasing and winding of the hawser under heavy storm or other dangerous status. Eminent is a professional manufactory for design, production, installation and service of Quick Release Hook(QRH). We learned about different design philosophies from various manufacturers, drawed on the pick of the basket and we have put

3 Quick Release Hook 卓冠the client's valuable comments into the basket together with our own experience. Eminent Quick Release Hook as an excellent product came out to the world. Especially, our designers with a solid experience continue to update in new material and new technical process in evey year. We have own 38pc patents only for Quick Release Hooks. We can supply you various type QRH(single, double, triple or quadruple hooks as required by the layout of the terminal, although other configurations, e.g. back-to-back,)with local manual hook release, electric, hydraulic and pneumatic remote release systems for the hooks, with the activation devices completely integrated into the hook assembly. And also can supply you the all type QRH installed mooring load monitoring system. We named it "Eminent Intelligent Hook". We can produce custom-made quick release hooks base on your requirement.

4 Quick Release Hook 卓冠Each hook is proof tested to 150% of its rated load, and the release mechanism is tested at full load rating at our own test facility and is witnessed by a surveyor from an independent Classification Society( LR,DNV,BV,ABS etc.). If remote release is incorporated the hooks can be released from a remote location (generally the control room or jetty office) as well as by activating a button on the control panel mounted on the side of the hook. Local displays of the mooring load tensions and audible and visual alarms can also be incorporated into the hook. 2. STANDARDS OCMIF: Mooring Equipment Guidelines TMXW1-2004: QRH (Shanghai Enterprise Standard) ASME, Section IX:Welding Qualifications ASTM A283 (Grade C) :Standard Specification for Low and Intermediate Tensile Strength Carbon Steel Plates ASTM A148 :Standard Specification for Steel Castings, High Strength for Non Structural Purposes ASTM A572 :Standard Specification for High Strength Low Alloy Columbium-Vanadium Structural Steel IEC: National Electrical Code, Intrinsically Safe Process Control Equipment for Use in Class I Hazardous Locations International Electrotechnical Commission Chinese Standards and the specification from the clients.

5 Quick Release Hook 卓冠3. Capstan Assembly In order to save time and to ensure maximum safety,each mooring unit is equipped with an integrated electric capstan motor assembly, the mooring ropes are lifted up to the mooring hooks by using the integrated electrical capstan. The capstan which is reversible is operated from a foot switch. Capstans are integrally mounted to the hook units and are certified for Ex area where applicable. This capstan complies with following specifications: Starting pull: 40KN = max line pull Running pull: 15KN-30KN = normal line pull Line speed: Back-stop: 20 m/min-25m/min 1.5 times normal line pull The capstan gear box is a self locking device to prevent the capstan head from turning in the opposite direction due to the weight of the mooring line at power off. The mounting model for motor is suggested: Horizontal. 4. STRUCTURE DESIGN MATERIAL LIST: PART STANDARD REMARK Hook GB-ZG35CrMo Equal to JIS SCCrM3 Shaft GB-40Cr Equal to ASTM A Connector GB-Q420A Equal to ASTM A572 Gr.65 Frame GB-Q420A Equal to ASTM A572 Gr.65

SPECIFICATION AND PERFORMANCE DATA Each hook will be tested as follows: Test load =1.5 times the SWL Release load = 1.0SWL Manual release force for release bar < 170N@SWL The movement range of hooks: Vertical: -15 (MLMS model), -5,0 to 45, 55. Horizontal: Single hook unit: 90 /90 Double hook unit: 90 /45 (left hook) 45 /-90 (right hook) Triple hook unit: 90 / 45 (left hook) 45 / -45 (Middle hook) -45 /-90 (right hook) Quadruple hook unit: Same as Triple hook unit.

INTELLIGENT HOOK Eminent Intelligent hook includes Remote Release System, Status Sensors and Mooring Load Moritoring System. It is possible to performe Quick Release hooks release, monitoring out of the dock in emergency. Ensure the Security of Jettyand operators. Remote Release System and Status Sensors To operate the release system from the remote location, a central remote control panel is included in the delivery. The panel includes: Hook release indicator Hook release push button A master release push button An emergency release push button A power on/off indicator lamp A power on/off switch

8 卓冠Quick Release Hook Digital display Display of hook loads Alarm indication Hook status (locked/unlocked) Failed release The remote quick release panel RQRP is connected via the LAN/Ethernet cabling to the hook stations. Functionality of the hooks is controlled from the network dedicated processor LAN Micro Sensor (LMS) built into the RQRP. Control of the hook s open/close functions is separated from the central computer system due to safety reasons. Furthermore a special coded message protocol between the RQRP and the hook station LAN/Ethernet unit is made to avoid accidental release of the hooks. The design of the RQRP allows to have multiple RQRP s connected both for hazardous and safe area. Mooring Load Monitoring System. (1) The Load Pin: The load pin is manufactured as a direct replacement for the hook swivel shafts. The load pin shall have the same safe working load as the corresponding mooring hook. The load pins are made of stainless steel 17-4PH, which is a special quality of stainless steel with an extreme high strength.

9 Quick Release Hook 卓冠(2) The Amplifier and Control Uint A dedicated amplifier module LM4 that is integreted into the control panel for capstan has been designed to protect the load cells from the cable network to aviod damage in case of induction caused by lightening. The amplifier module is equipped with a proceesor unit that will track of the loads. This means that the load values are memorized in this amplifier module keeping track of about 1year of data. Should the central computer for some reason fail, the history is always available in the amplifier unit.temperature ranging from -40 to 85 (3) Load Monitoring on Central Computor The load information is in real-time sent to the central computor for visualization. This central computor acts as server for the data recorders located in the hook remote release control panel cabinet. The central computor system will also host the Vessel Docking Aid System Software. Display screens will be available to the operator thought a standard MS windows interface and will form an intergreted package.
