International (HAI) (www.rotor.com). The
following recommended practices for offshore
helicopter operations are based on guidance
developed by HSAC for use in the Gulf of Mexico,
and provided here with their permission. While not
regulatory, these recommended practices provide
aviation and oil and gas industry operators with
useful information in developing procedures to avoid
certain hazards of offshore helicopter operations.
NOTE−
Like all aviation practices, these recommended practices
are under constant review. In addition to normal
procedures for comments, suggested changes, or
corrections to the AIM (contained in the Preface), any
questions or feedback concerning these recommended
procedures may also be directed to the HSAC through the
feedback feature of the HSAC web site (www.hsac.org).
b. Passenger Management on and about
Heliport Facilities
1. Background. Several incidents involving
offshore helicopter passengers have highlighted the
potential for incidents and accidents on and about the
heliport area. The following practices will minimize
risks to passengers and others involved in heliport
operations.
2. Recommended Practices
(a) Heliport facilities should have a designated
and posted passenger waiting area which is
clear of the heliport, heliport access points, and
stairways.
(b) Arriving passengers and cargo should be
unloaded and cleared from the heliport and access
route prior to loading departing passengers and cargo.
(c) Where a flight crew consists of more than
one pilot, one crewmember should supervise the
unloading/loading process from outside the aircraft.
(d) Where practical, a designated facility
employee should assist with loading/unloading, etc.
c. Crane−Helicopter Operational Procedures
1. Background. Historical experience has
shown that catastrophic consequences can occur
when industry safe practices for crane/helicopter
operations are not observed. The following recommended
practices are designed to minimize risks
during crane and helicopter operations.
2. Recommended Practices
(a) Personnel awareness
(1) Crane operators and pilots should
develop a mutual understanding and respect of the
others’ operational limitations and cooperate in the
spirit of safety;
(2) Pilots need to be aware that crane
operators sometimes cannot release the load to cradle
the crane boom, such as when attached to wire line
lubricators or supporting diving bells; and
(3) Crane operators need to be aware that
helicopters require warm up before takeoff, a
two−minute cool down before shutdown, and cannot
circle for extended lengths of time because of fuel
consumption.
(b) It is recommended that when helicopters
are approaching, maneuvering, taking off, or running
on the heliport, cranes be shutdown and the operator
leave the cab. Cranes not in use shall have their booms
cradled, if feasible. If in use, the crane’s boom(s) are
to be pointed away from the heliport and the crane
shutdown for helicopter operations.
(c) Pilots will not approach, land on, takeoff,
or have rotor blades turning on heliports of structures
not complying with the above practice.
AIM 2/19/04
10−2−2 Special Operations
(d) It is recommended that cranes on offshore
platforms, rigs, vessels, or any other facility, which
could interfere with helicopter operations (including
approach/departure paths):
(1) Be equipped with a red rotating beacon
or red high intensity strobe light connected to the
system powering the crane, indicating the crane is
under power;
(2) Be designed to allow the operator a
maximum view of the helideck area and should be
equipped with wide−angle mirrors to eliminate blind
spots; and
(3) Have their boom tips, headache balls,
and hooks painted with high visibility international
orange.
d. Helicopter/Tanker Operations
1. Background. The interface of helicopters
and tankers during shipboard helicopter operations is
complex and may be hazardous unless appropriate
procedures are coordinated among all parties. The
following recommended practices are designed to
minimize risks during helicopter/tanker operations:
2. Recommended Practices
(a) Management, flight operations personnel,
and pilots should be familiar with and apply the
operating safety standards set forth in “Guide to
Helicopter/Ship Operations”, International Chamber
of Shipping, Third Edition, 5−89 (as amended),
establishing operational guidelines/standards and
