QUICK RELEASE MOORING EQUIPMENT
E-Sea Hook
Safe and easy release of mooring lines
Mooring and monitoring of big ships
Advanced monitoring of loads

The E-Sea Hook System
MARIMATECH is the world leader in LASER DOCK-
ING SYSTEMS and MOORING LOAD MONITORING
SYSTEMS. A logical consequence of this market
position has been to add Quick Release Mooring
Hooks into our range of products, enabling us to
offer complete integrated systems.
16 years of experience with our own Mooring Load
Monitoring Systems and various designs of Quick
Release Hooks (QRH) have given us a solid experience,
which has resulted in a QRH design, that
meets the requirements of the latest safety standards
as well as a new dimension of automations.
Typical Applications are:
Oil jetties
LNG/LPG jetties
Single Point Mooring (SPM)
Offshore FSO/FPSO
Ferry terminals
The E-Sea hook comes in a large number of variations
covering hook capacity from 10 ton up to
250 ton. They can be delivered with just manual
release as well as electrical and hydraulic remote
operated release systems. The E-Sea Hooks
are often fi tted with load pins, to measure the
dynamic load in the mooring lines. The QRH is
equipped with integrated or freestanding capstans
designed to the required pulling load. In
addition to the basic functions the E-Sea Hook
offers a number of new refi nements to improve
safety and automations.

The E-Sea Hook meets the latest requirements of
handling mooring lines with a minimum of labour,
to be able to release mooring lines in an emergency
situation under any load conditions. The
wide range of hooks covers ships of any size and
type. The E-Sea Hook is designed for hazardous
areas as well to comply with the international
regulations now also including ATEX.

System Components
The E-Sea Hook system has a modular design
that makes it possible to meet nearly any requirements.
Solutions from cost effective manual types
to remote operated systems that optional can be
equipped with load pins, display/alarm panels and
hook status management. Everything is designed
for extreme conditions. Even the associated electronics
is made of mil classifi ed components to
withstand environmental conditions in the range
of –20°C to +85°C.
The hook itself is designed to be operated without
using force of any kind to avoid damage to
personnel. The capstans are delivered with brake
motors and the operation takes place from a foot
hybrid switch, made of stainless steel. There are
no moving parts and the foot switch controls both
pull-in and payout. The foot hybrid switch is easy
removable to avoid damage.
The hook foot switch is IP68 and no moving parts

The Safeguard Panel
The SAFEGUARD panel is the local display and
operating panel from where the user operates
the hook station. This panel with all its options
contains the following:
Remote operation of the Quick Release function
Display that indicates the hook loads
Alarm that will activate sound and fl ash in case
of overload
Connector for removable foot hybrid switch
The advantage of the SAFEGUARD panel is that the
operator has control of the hook release function
from a safe location. Furthermore the display
will indicate the hook station status and provide
alarms in case of malfunction and overload. The
panel is designed for hazardous area and the
construction is made of stainless steel 316.
Mooring Load Monitoring
Quick Release Hooks fi tted with load pins have
integrated the LMS-4 amplifi er and input/output
module. This module takes control of all functionality
on the hook station also including the optional
Remote Quick Release operation. The LMS-4 has
internal memory (Black-box function) that automatically
will keep up to one year of history in the
memory. The data and control line is LAN/Ethernet
allowing for both electrical and fi bre optical
connection.
The load cells are EEx certifi ed. They are fi lled
with a special compound to avoid condensation
as well as protecting all components from the
release chock. Cables are protected in hydraulic
hoses made of a material that will withstand salty
marine environment. The load cells are fi tted with
redundant gauging (built-in spare).

Remote Quick Release Control
The E-Sea Hooks can be equipped with a Remote
Quick Release option that can be all electric or
hydraulic activated. The hydraulic offers back-up
pressure for release from the power pack should
the main electrical power fail.
The remote quick release panel is designed for
safe and easy operation. It can be located in both
safe and hazardous areas and several panels can
be connected offering control from more than on
location. The panel has built-in display providing
the user with mooring load data as well as status
and alarm functions.
The panel is made of stainless steel and fi ts into a
19” rack consoles as well as ordinary cabinets.
Principles of Operation
The E-Sea Hook is designed for both manual and
remote control. It has been a demand in the design
that the hooks are easy to open and close with
extreme low force. This design leads to increased
safety. The electrical system is the LAN/Ethernet
which simplifi es cabling and the latest option is
allowing us to establish a loop network. Should a
cable break in the loop the functionality is not lost.
The below schematic shows a typical network that
also allows connecting other sensors, displays
etc. into the LAN data network.

DockMaster Software
The DockMaster software package provides the
users with easy to use graphical interfaces to
monitor the system. The built in user management
makes the system secure against confi guration
failures. The system can easily be extended
with an unlimited number of DockMaster clients
without any loss of performance.

Precalculation of Mooring Loads
A pre-calculation program (OPTIMOOR*) is available.
OPTIMOOR calculates the theoretical loads to
a given mooring pattern and ship from predicted
wind loads and loads from sea current. The OPTI-
MOOR works as an integrated part of the Mooring
Master software.
OPTIMOOR is a very useful tool for precalculating
the loads in the mooring lines
prior to the ships arrival.

Project management.
In order to secure a successful implementation
of a quick release hook system, MARIMATECH
treats every job as a project rather than a standard
installation.
MARIMATECH has trained experts to take care
of the different tasks within the project such as
documentation, Factory Acceptance test, project
management, training of personal etc

After the system is in operation MARIMATECH’s
service and support staff are here to help in case
of any problems. This can be done on an ad hoc
basis or by choosing one of the service products
we offer.
Although the quality of the equipment is fi rst
class, and we have done a good job to bring the
maintenance down to a minimum, we recommend
a preventive maintenance agreement in order to
prolong the lifetime of the system.
