1.0 HELICOPTER OPERATIONS GUIDELINES

1.1 PURPOSEAND SCOPE

The purpose of the following instruction is to establish standardized responsibilities andactivities for helicopter operations. This procedure covers all Company vessels withhelicopter landing decks.

1.2 RESPONSIBILITIES

The Master, via the appointed person in charge of the helideck team, H.L.O,. has thedirect overall responsibility for all helicopter operations onboard.

The MasterHLO is responsible for all operations, which are conducted on the helideck. Hewill be specifically responsible for ensuring the following:a) That all personnel are aware that the helideck must be cleared prior to take-off and

landing (of both people and objects).

b) That all the required equipment is in position and in full working condition (safetyequipment, lighting, rescue and fire fighting equipment).c) That all personnel involved with the operation of the helideck are proficient in the

operational requirements. This includes both normal and emergency conditions.d) That passengers are correctly controlled during embarkation and disembarkation. The

responsible person will be responsible for ensuring the safe disembarkation andembarkation of all personnel travelling in the helicopters as well as ensuring that safeconditions exist on the helideck before, during and after both take off and landing.

e) The vessel may operate in areas where local or national rules apply, these must be

followed.f) The vessel charterer may have additional requirements, which he should make known

to vessel.

1.5 INSTRUCTIONS

1.5.1 Person in Charge of the Helideck Team H.L.O.

1.5.1.1 General

The responsible person HLO is to ensure that:a) Prior to landing and take-off the helicopter deck is free from all loose articles and

anything that may catch the rotors.b) All warning and signal lighting is on and working. Floodlights are to be checked

prior to landing and to be turned on only by request of the pilot.c) All non-authorized personnel are kept well away from the helideck before

landing and until the helideck is clear.d) No smoking on the helideck.e) Crane operations are terminated before landing and until the helicopter is clear

of the vessel.f) Fire fighting Heliguard team is ready and dressed with properclothing and

equipment as required.g) Safety nets are checked and safely secured with proper tension.

Cargo and passenger manifests are duly in order and available to be handed over tothe pilot.


7/23




Advise cranes to stop work and park booms clear of the 210-degree

sector. If the vessel is working alongside an installation, platform cranes mayalso have to be stopped. This is achieved by contacting the platform radiooperator. In the case of helicopter movements to an adjacent platform, vesselcrane movements are required to cease and booms parked clear of flight paths.

Restrict access to helideck and advise non-authorized personnel to leavethe area.

Unlock and check the safety equipment box.

Advise fire crew to standby.

Ensure standby vessel (if available) has been informed of helicopter.

Ensure that the Engineroom control room is informed.Immediately before landing, the H.L.O. will make the following checks:

Confirm that cranes have stopped work and booms are clear.

Ensure that helideck fire crew is dressed and in place.

Ensure that helideck is clear of non-authorized personnel.

No smoking on the helideck.

Inform the O.C.C. and Engineroom control room

Ensure that the fire pump is running if no start is close to the helideck.

1.5.1.3 Responsibilities and Duties After Landing (Rotors Running)

After the helicopter has landed and the anti-collision light has been switched off, theH.L.O. will ensure that no personnel are allowed to approach the helicopter untilinstructed to do so. The H.L.O. is responsible for the followingtasks :-


8/23




All outgoing passengers will be loaded and checked against the

manifest. Freight and baggage will be loaded and checked against the manifest.

The flight crew will supervise the loading to ensure that it complies with theregulations and that all items are safely stowed.

Certain goods, classified as dangerous, are not allowed to be carried byhelicopters. The Administrator, or appointed person, as directedby the Master, will conduct a Security Baggage Search toensure thefollowing items are not carried. Goods classified as

dangerous include: Alcohol

Compressed gases

Fire-arms

Corrosive liquids (including mercury)

Offensive weapons

Magnetic material

Matches

Oxidising materials Lighters

Poisons

Drugs (unless prescribed by a doctor)

Flammable liquids

Noxious irritating substances

Polymerizable materials

Radioactive materials

Any articles possessing other inherent characteristics, which make themunsuitable for carriage by air, unless correctly packed.

When the helicopter is ready for take off, the H.L.O. will ensure that all the

Standby in view of the pilot outside the helicopter cockpit, clear of the

rotors. On request by the pilots to start No.1 or No.2 engine (one or two fingers up) to

carefully observe the engine during start-up.

On the request by the pilot to start the other engine (one or two fingers up), tocarefully observe the engine start-up.

In start up conditions the rotors may dip towards the deck more than in constantrunning and this is to be guarded against.

After rotor engagement, move to right hand side of helicopter cockpit and

standby. After departure of the aircraft the H.L.O.will inform the O.C.C. OOW

and Engineroom control.

The H.L.O. will dismiss the Heliguard crew after the pilots giveclearance.

1.5.1.7 Safe Helideck Procedures

If wind speeds exceed 45 knots (1 minute sustained) over the helideck, helicopteroperations should be carefully considered.

The H.L.O. has the authority to stop/suspend helicopter operations if he considersthe helideck to be unsafe for personnel.


10/23




1.5.2.1 Instructions for Firemen

The Helideck Fire Crew will be fully trained in the operation of the fire fighting andemergency equipment.

During landing and take off the Firemen is are to be in a protected position adjacentto the helideck, but still to have full overview of the deck.

1.5.2.2 Helicopter Landing Procedure

A qualified H.L.O. will be appointed for landing and take off.

The appointed H.L.O. will be in command and will have an aeronauticalradio, to allow direct contact with the Helicopter Pilot and theO.C.C. OOW

The H.L.O. will be advised by the O.C.C. OOW of an expected helicopter

landing approximately ten thirty (see 1.5.1.2) minutes before the estimated time ofarrival. The Heli-crew will go to the helideck and put on the fire suits provided.

The H.L.O. will ensure that all appliances are in position and in a state of readinessfor operation if required.

When the helicopter is landing, the H.L.O. will pay particular attention to theengines to ensure that there is no fire. If a fire is apparent, the H.L.O. will inform

the Pilot. The Heliguard teamwill be dressed ready to proceed tofight any fire as directed.

If any other emergency should occur, such as a helicopter crash, the emergencyd ill b f ll d


11/23




In case of a jet engine fire, warn the pilot immediately. After clearance from the

pilot, direct the CO2 fire extinguisher lance into the marked red and white fireextinguisher opening on the side of the engine.

In case of a fire on the flight deck or underneath the helicopter, warn the pilotimmediately and then start to fight the fire.

1.5.3 Radio Operator

NOTE: The Radio Operator is the bridge officer on watch.

1.5.3.1 General

The Radio Operator will be advised of the E.T.A. of all helicopters due to use thevessel helideck. This notification will normally be given at least one hour beforeE.T.A.

No helicopter will be allowed to land or take off unless radio communications have

been established with the field operations centre (where applicable).

The standby vessel must be informed of all helicopter movements.

1.5.3.2 Landing and Take Off

12/23




Temperature (degrees centigrade)

The O.O.W. will ensure that the H.L.O. and the helideck Fireteam is inposition on deck ten minutes before the E.T.A. and that the H.L.O.informshim via the aeronautical radio when the helideck is mannedand ready.

On the helicopter's approach to the vessel, the H.L.O. may if requestedprovide details of the return load, number of return passengers and time forthe ground stop (should be less than 20 minutes).

The H.L.O. and O.C.C. will remain available for constant communicationswith the Pilot throughout landing.

When the helicopter is preparing to take off, the H.L.O.will receive the allclear signal from the Pilot who will then give the all cleardirectly to the Pilot.

The H.L.O. will be in constant communication with the Pilot until the helicopteris clear of the vessel. Thereafter, the O.C.C. will maintain a listening watch onhelicopter UHF until the helicopter has established communication with the next

station. At departure, the Administrator/Clerk/Medicwill send a message to the

appropriate heliport stating:

Call-sign of helicopter

Time of departure

Estimated time of arrival

Number of persons onboard

1.5.3.3 Emergency Situation


13/23




1.5.4.1 Considerations

Fires should be attacked from the windward side. Due to a high risk of re-ignition, acombination of dry powder and either water or foam should be used. Powder willextinguish flames; water will cool the object. A layer of foam will insulate objectsfrom the heat of the fire. Water spray in combination with foam will break down theflames. If the fire is too fierce to be extinguished with the available equipment, themaximum amount of water spray should be applied to cool surrounding objects.Special attention should be paid to high pressure cylinders and piping. Foamshould be applied to form a carpet around the wreck to prevent a fuel spill fire.

General extinguishing shipboard procedure:1. Initiate FIRE ALARM status, inform the O.C.C. OOW who will make

P.A.2. Prepare back-up Rescue Fire teams to assist Heliguard.3. Dry powder should immediately be applied at the maximum rate possible. This

will extinguish or retard the fire until more equipment is brought to bear.

4. Applying foam to the object and the immediate surrounding area shouldcommence as quickly as possible.

5. The use of water jets or spray directly onto the helicopter should only beconsidered if the combined use of powder and foam proves insufficient, as watermay break down the foam layer.

6. Water spray should be applied to cool surrounding objects.7. Establish and maintain contact with the bridge orO.C.C. (as applicable).8. Consideration should be given to maneuver the vessel to position the fire on the

downwind section of the vessel to blow the heat/flames away from additionalfuel.

9. A PA announcements should be made to have all non essential personnelmuster at an appropriate muster station.


14/23




The Master has overall responsibility and co-ordinates all activities according to hisjudgment of the total situation. He will issue calls for outside assistance ifconsidered necessary and order auxiliary vessels in the area to appropriatepositions. In any event he is to inform the USCG or local authority if operatingoutside US waters in all circumstances. Delay in doing this has proved, in the pastto have cost lives.

If notice of an intended emergency landing is received, the fire alarm is soundedand information on the situation passed on by the vessel public address (PA)system.

If diving bell is launched, abort the operations.

Fly off any helicopter on the deck and "hold off" incoming aircraft.

Check that the approach and overshoot areas are clear. Ascertain souls on board(SOB).

1.5.4.3 General Duties

H.L.O. observing crash or other incidents during landing or taking-off which arethat is, or may develop into, an emergency situation, will immediately inform theOOW and man the main extinguishing equipment.

Chief Officer

Discontinues all ongoing operations Directs Back-up squad to put on entry suits, B.A. and prepare for

rescue operation.

Directs the preparation of foam and dry powder extinguishing system,


15/23




Prepares to assist in rescue and fire fighting operations in consultation

with the Master. Deploys assigned teams to shut down ventilation and close doors,

hatches and flaps in air inlets not affecting the maintenance of power.

Directs the elimination of ignition sources in the hazardous areas.

Organizes protection of vital arrangements in consultation with theMaster.

Helicopter Landing Officer in Charge of Helicopter Landing Deck Supervises damage control operations on helicopter landing deck by:

Initiating an immediate evacuation of all personnel from the wrecked helicopter.

Directing measures to prevent ignition of fuel spills.

In case of fire, directing a massive attack upon the fire. In case of fireimmediately call the bridge OOW (or DP control center as applicable) over theradio.

Directing rescue team to appropriate approach for evacuating operation.

Establishing protection and cover for rescue team. Establishing safeguarding of the area surrounding the wreck.

Seeing that injured people are brought to a safe position and given first aidtreatment.

Keeping Master informed of the development.

Diving Supervisor

Abort diving operations.

Recovers bell. Prepares divers for hyperbaric evacuation if required. (Check

with the bridge or DP control center).

Assemble surface divers (if available) for rescue


16/23




In the situation of an actual crash landing on the helicopter landing deck, the

Heliguard fireteam should: If no fire is apparent, but there is a fuel spill, cover the spill

with a foam blanket to prevent ignition.

Ensure a fire watch is maintained, particularly for escaping fuel, which may runto lower decks.

Passenger Rescue

The doors and hatches on helicopters are of simple construction and are

unlikely to be jammed. If they are jammed, prise them open. If forcible entry is necessary cut only at recognized break in points such as

emergency exits and windows. If a helicopter is lying on its side, support theoccupants carefully when seat harnesses are released (single seat belts areused for passengers).

Flight Deck RescueThere are emergency exits on the flight deck. If perspex panels have to be brokento gain access, spray them with CO from extinguisher (this will make them brittle)

and then tap sharply with a fireman's axe. The pilot has a four point inertia reel typeseat harness. If he has to be released, undo it by operating the normal releasemechanism.

Stopping the Aircrafts EngineWhen the helicopter is in the normal position and the pilot and/or crew areincapacitated and the engine and rotors are still running:

Either : Stop the engine by spraying CO/dry powder/water into the air intake.

Although the engine is stopped the rotor blades will continue to rotate for a shorttime.

Or : Gain access to the cockpit. Close down the engines by shutting off fuel andbatteries. Fuel: pull both T - handles, shut down fuel cocks. Batteries: switch


17/23




The shorter throw of secondary fire fighting agents (CO2, Dry Powder) is more

advantageous (owing to the close proximity of the cabin, engines and fueltanks).

Another significant feature is that a helicopter takes off and lands without forwardspeed, so generally speaking there is less disruptive damage to a helicopter and theoccupants are more likely to survive.

1.5.4.5 Radio Operator (normally OOW)

Upon notification of a helicopter crash, contact local air traffic control and informthem of the situation and establish communication with the shore base for handlingmessages. In case the radio equipment cannot be operated or the radio station hasto be evacuated, call the Master for further orders. Obtain possible VHF radio andestablish contact with the stand-by boat for the relay of messages.

1.5.4.6 Officer of the Watch (OOW)

The OOW should: Instigates diver "red alert".

Go to yellow alert for well intervention operations.

Makes a PA announcement advising all personnel of the situation.

Informs the stand-by boat (if available).

Informs the platform OIM if vessel is within the 500 metre zone.

1.5.4.7 All Personnel

In case of an emergency situation on the helicopter landing deck there will be a PAannouncement. Fire Team reports to Fire Station. Two members don fire entrysuits, the remaining members put on protective garments and assist.


18/23




request assistance from all vessels in the vicinity to the best advantage of the

operations. Helicopters in the area will be called upon to approach the site of theaccident and relay the first situation report to all parties preparing rescue efforts andalso make the first rescue attempts if the situation permits. The Master will issuecalls for other outside assistance, also notify USCG (or other local authority ifoutside US waters) and keep them informed of the proceedings and act asCommander on scene.

1.5.5.3 Procedure

Anyone observing a helicopter downing, shall immediately inform the bridge (or DPcontrol centre as appropriate) about the situation.

Helicopter Landing Officer in Charge of Helicopter Landing Deck

Contact Master for determination of mode of action.

Abort any diving operations in progress. Request diving team to prepare surface

divers for search operations. In case decision to launch Lifeboat is reached:

Join lifeboat crew, check equipment and communications and getwaterborne.

Maintain contact with the Pilot on the aeronautical radiofor any advice or instructions, if the aircraft is still afloat.

Approach the wreck and direct rescue operations by VHF. Survivors shouldbe transferred to the nearest vessel, with Medical facilities.

On Duty OfficerOn information of helicopter ditch, announce by PA system that helicopter hasditched and also other known particulars of the situation. If diving bell is launched,


19/23




1.5.6 Notification Procedures

Having informed the USCG (or appropriate local authority) and the local platform based airtraffic control, the Master should immediately inform the shore based EmergencyResponse Team.

Shore base will inform:

Owner/operator of helicopter (if known).

Other helicopter companies. Department of Transport Air Accident Investigation Branch (AAIB).

Police

Company Doctor (who will in turn alert hospital facilities as necessary).

Customs and Excise (for rapid clearance of personnel and services needed duringemergency action).

Immigration Department.

Information to be reported should include:

Helicopter type and call sign (if known).

Number of personnel on board.

Name of vessel or installation

Position of crash in relation to vessel or installation.

Description of incident.

Time of incident.

Details of any known injuries (names of injured persons not to be given over 'open'communications).

Weather conditions on scene.

Actions taken on the scene.


20/23




If the helicopter is definitely known to have crashed and no message has been sent orreceived, a May Day situation should be declared and messages sent to the coastal and airradio station.

Depending on the situation, where and how the helicopter has crashed or crash landed, theunits directly involved shall immediately give all possible assistance.

Even in moderate waves, helicopters will most likely capsize, but will stay afloat for hours ifimpact does not burst open the fuselage. The cabin will gradually be flooded. Aftercapsizing, the emergency exit doors cannot be removed until water pressure is equalized.On most helicopters, pop out floats are mounted on the lower part of the fuselage or frame.The floats will inflate on immersion. Fuel tanks, located in the lower part of the fuselage,may be leaking.

1.5.8 Emergency Exits

Special attention should be paid to the wide doors on the helicopter, as victims may have

inflated their lifejackets in addition to wearing bulky survival suits and may have difficultiesto get out.

1.5.9 Rescue Operations

Rescue operations should be carried out from small boats to avoid puncturing floats anddealing severe blows to the wreck. Do not make attempts to perforate the fuselage to getaccess to the cabin; the widest door should be the prime target in making access. If diversare available, they should enter the cabin to assist survivors in escaping. Survivors shouldbe transferred to rafts until rescue operations are completed. Severely injured personsshould be evacuated immediately after receiving first aid treatment.

If required the vessel should cease diving operations in a safe manner and give direct

1.5.10.2 Pre Arrival

The helicopter is to contact the O.O.W. on the agreed channel/frequency; thisshould be at an interval as long as possible prior to landing and at least 30 minutesprior to the estimated time of arrival (ETA). 123.05 MhzThe Pilot shall make his ETA known and after discussion with the O.O.W. in theO.C.C. the Pilot will let the vessel know his requirements regarding vessellocation, heading and speed.

1.5.10.3 Arrival

The Pilot should contact the H.L.O. to ask for a GREEN DECKto ensurethat the vessel is ready to receive the helicopter and get permission to land.The pilot shall contact the HLO to ask for a green deck and to get permission toland. This will verify that the vessel is ready to receive the helicopter.
