Disembarking and embarking passengers

• Disembarking and embarking passengers may be carried out
with the rotor turning or motor and blades stopped
• In the case of a complete stop, it is important not to approach
the helicopter before the rotor completely stops because the
blades of some helicopters (especially with the S76), at low
speed, may "drop" and pass at a height lower than the head of
a man.
• Under no circumstances may passengers go round the
helicopter, whether by the front or the back. Only the HLO and
the HDA are allowed to do it, by the front only, to collect or
bring back baggage, and only when access to the
compartment, stairs side, is impossible (see Annex 2:
Circulation around Helicopter).
• After landing, the pilot gives the HLO permission to approach
with a thumb-up and by switching off his rotating navigation
lights.

30

The HLO then has to carry out the following actions

• Advance to the helicopter by its side safety area according
type of helicopter, see drawing in Annex 1
• Take receipt of the manifest of disembarking passengers from
the pilot.
• Check on the action of the HDA, who collects the baggage of
the disembarking passengers and brings it close to the stairs.
• During this time, the passengers wait in the helicopter.
• Long items will be carried horizontally to prevent
contact with rotor blades.
• Open the doors descent stairs side, and this side only, for
disembarking passengers, and leads them out of the helideck
by the side of the helicopter facing these stairs.
• Passengers descend with their life jackets on.
• Check on the collecting of life jackets from disembarking
passengers by the HDA outside the helideck and distribution
of them to embarking passengers
• If embarkation is done with the rotor turning, all
passengers must put on their life jackets before going
up on the helideck.
• Check on loading of embarking passengers' baggage in the
helicopter's baggage compartment by the HDA.
• Guide embarking passengers to the doors of the helicopter,
stairs side, (and this side only), and checks on the correct
buckling of safety belts.
• Close all helicopter doors.
• Deliver to the pilot, four copies of the manifest of embarking
passengers, freight and retains receipt of a signed

1. Supply vessel request for approaching bunkering station.
2. Bunkering safety measures have to be implemented before
the connection.
3. When connection is completed, exchange of safety check-lists
is done to ensure each other is ready for the bunkering
operation: barge safety officer and supply vessel captain have
to fill and sign.
4. Bunker ticket has to be checked and signed by both chief
engineers.
5. When confirmation is done on each side, pump is started at a
slow rate to check tightness of connections and leaking if any:
this is the integrity check.
6. Then a pump emergency stop is performed to ensure that it is
working normally.
7. If all safety checks are performed without any fault, pump rate
is increased until the maximum admissible rate by the
installation.
8. One engineer is on stand-by at the manifold during the whole
bunkering operation.
9. Soundings have to be regularly checked to avoid any overflow.
10. Safety officer will remain fully available and maintain radio
watch.
11. If topping of tanks is necessary, pump rate will be decreased
accordingly until the completion of tanks.
12. When transfer is completed, pump is stopped and bunker
confirm receipt will send to the receiving installation.
13. In normal conditions there is no need to flush the line as the

Description
The Nor Crane & Winch‘s Hydraulic Mooring Winch model type
NCW MW-85-200-H is designed for safe and reliable personnel
handling operation.
This hydraulic mooring winch consists of a single hauling drum
mounted on a high tensile steel main shaft, supported on the
fabricated winch base-plate by heavy duty roller type bearings.
The bearings are mounted in steel housings, fitted with external
grease lubrication points, bolted to the winch base-plate.
The drum is fitted with a spring loaded, hydraulic released band
brake, giving a fail-safe to “ON” mode during operation. This brake
is a wrap-up design consisting of two halves warp around the race
of the drum flange. The brake would operate through a hydraulic
cylinder and spring loaded system, through mechanical linkages
to provide the required holding load. All brake straps are lined
with a high grade non-asbestos marine lining that is bolted to
position. A spanner is provided to manually override onto the
cylinder in a case of emergency. Also a hydraulically operated
ratchet assembly is provided for stopping the
drum at full braking load in as standby of drum brake.
The drum can engaged or disengaged by means of a hydraulically
57 operated dog clutch, which is installed at the intermediate shaft
to allow the engagement of drum to drive unit.

Nunce

Anchor winches

A mechanical fresh water cooled disc tension drag brake is installed
on another pinion shaft to ensure the drum is under controlled
payout dynamically for operation of anchor deployment.
Transmission would be from two low speed high torque medium
pressure hydraulic motors.
The motors would be positioned at one side of the winch, driving
through a guarded doubled stage spur reduction gearing.
An automatic spooling device is provided for the wire spool
smoothly on drum. This device comprises a lead-screw and drive
tongue, guide bar, side support frames, fabricated bushed carriage
completed with vertical rollers, manually operated clutch and
chain drive mechanism driver and driven sprockets, chain and

DESIGN
The crane is designed and constructed in accordance with API SPEC
2C,
Specification for Offshore Cranes, 6th edition, September 2004.
The crane is designed to provide the SWL capacities at the required
load, radii and speeds.
These SWL capacities are used to determine the Category 1 (static)
and Category 2 (dynamic) design loads as defined in API SPEC 2C.
For the purpose of evaluating the dynamic ratings for lifts from
boats, off-lead and side-lead angles are used as stated in the
technical data for the sea states indicated.
Also the maximum operating wind speed is included in the
evaluation of side forces.
The out-of-service wind speed is considered with the boom in the
horizontal position restrained in a rest.
Detailed calculations are prepared for all primary loaded members
of the crane, such as:
• Pedestal adaptor.
• Swing Circle bearing.
• Revolving Base structure.
• Frame.
• Boom.
• Running ropes.
• Boom foot pins and sheave pins, etc.
• Hoist winches drums and shafts.

“Setup” section for details). This condition is signaled visually by a
yellow area in the current load bar graph.
Overload
This means that the current load, expressed as a percentage of the
load limit, is greater than a configured threshold value (see the
“Setup” section for details). This condition is signaled visually by a
red area in the current load bar graph.
Communications fault
A red, blinking circle indicates a wrong communication between
screen and the CPU. This should never happen, as long as the
instrument has not been damaged; if the indication appears during
operation, please contact the manufacturer for assistance.
NOTE: A green blinking circle appears in normal communication.
Service messages
Appears when machine needs service maintenance.
Collision Information
Screen displays possible actions for crane operator, in collision
conditions (see the “Anticollision” section for details.)

Main screen: During normal operation, the
instrument screen appears as follows:

2.1 - Load bar graph
The colored bar shows the current load applied to the hoist, in terms of
percentage of the acceptable load. The instruments computes the
acceptable load in real time, based on the sea state and current luffing value.
A yellow area in the bar indicates that the current load is greater than the
pre-alarm threshold.
A red area in the bar indicates that the current load is greater than the alarm
threshold.
2.2 - Current load
To the right of the bar graph, the load currently applied to the hoist is shown,
expressed in ton.
2.3 - Load limit (SWL)
The load limit (Safe Working Load), depending upon the sea state, selected
hoist (when available) and working radius, is displayed immediately below
the current load value.
2.4 - Radius
Working radius is expressed in meters.
2.5 - Luffing
The luffing value is expressed in degrees.
2.6 - Communication icon
113 A green circle indicates a right communication. A red circle indicates a wrong
communication
