Quick Release Hook

Quick Release Mooring Hook

1. GENERAL DESCRIPTIONInstalled at dock, Quick release hooks arespecial equipments for winding and tying ofships. They are the update products ofmooring dolphins. Compared with cleat, theyreduce working intensity, increase workingefficiency and improve safety and reliability.

Quick release hook consists of integratedelectrical winch and release systems. Theyare suitable for large tonnage ships mooringharbors that require fewer workers and quickreleasing and winding of the hawser underheavy storm or other dangerous status.

Eminent is a professional manufactory for design,production, installation and service of QuickRelease Hook(QRH). We learned about differentdesign philosophies from various manufacturersdrawed on the pick of the basket and we have put

Quick Release Hook

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 newtechnical process in evey year. We have own 38pc patents only for Quick ReleaseHooks.We can supply you various type QRH(single, double, triple or quadruple hooks asrequired by the layout of the terminal, although otherconfigurations, e.g. back-to-back,)with local manual hookrelease, electric, hydraulic and pneumatic remote releasesystems for the hooks, with the activation devices completelyintegrated into the hook assembly. And also can supplyyou the all type QRH installed mooring load monitoringsystem. We named it "Eminent Intelligent Hook".We can produce custom-made quick release hooks base on your requirement.

Quick Release Hook

Each hook is proof tested to 150% of its rated load, and the release mechanismis tested at full load rating at our own test facility and is witnessedby a surveyor from an independent

Classification Society LRDNVBVABS

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.

3. Capstan Assembly

In order to save time and to ensure maximum safety,Each mooring unit is equipped withan integrated electric capstan motor assembly, the mooring ropes are lifted up to themooring hooks by using the integrated electrical capstan. The capstan which isreversible is operated from a foot switch.Capstans are integrally mounted to the hook units andare certified for Ex area where applicable.This capstan complies with following specifications:Starting pull: 40KN = max line pullRunning pull: 15KN-30KN = normal line pullLine speed: 20 m/min-25m/minBack-stop: 1.5 times normal line pullThe capstan gear box is a self locking device to prevent the capstan head from turning inthe opposite direction due to the weight of the mooring line at power off.The mounting model for motor is suggested: Horizontal.

5. 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

Quick Release Hook

Digital display Display of hook loads Alarm indication

Hook status (locked/unlocked) Failed releaseThe remote quick release panel RQRP is

connected via the LAN/Ethernet cabling to

the hook stations. Functionality of the hooksis controlled from the network dedicated

processor LAN Micro Sensor (LMS) built into

the RQRP. Control of the hooks

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 RQRPs connected both forhazardous 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.

Quick Release Hook

(2) The Amplifier and Control Uint

A dedicated amplifier module LM4 that is integreted into the control panel for capstanhas been designed to protect the load cells fromthe cable network to aviod damage in case of

induction caused by lightening. The amplifier moduleis equipped with a proceesor unit that will track of

the loads. This means that the load values arememorized 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 datarecorders located in the hook remote release control

panel cabinet.The central computor system will also host the

Vessel Docking Aid System Software. Displayscreens will be available to the operator thought astandard MS windows interface and will form an

intergreted package.
