(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 safe practices sufficient to safeguard helicopter/tank-er operations.
(b)Appropriate plans, approvals, and com-munications must be accomplished prior to reaching the vessel, allowing tanker crews sufficient time to perform required safety preparations and position crew members to receive or dispatch a helicopter safely.
(c)Appropriate approvals and direct commu-nications with the bridge of the tanker must be maintained throughout all helicopter/tanker opera-tions.
(d)Helicopter/tanker operations, including landings/departures, shall not be conducted until the helicopter pilot.in.command has received and acknowledged permission from the bridge of the tanker.
(e)Helicopter/tanker operations shall not be conducted during product/cargo transfer.
(f)Generally, permission will not be granted to land on tankers during mooring operations or while maneuvering alongside another tanker.
e.Helideck/Heliport Operational Hazard Warning(s) Procedures
1. Background
(a)A number of operational hazards can develop on or near offshore helidecks or onshore heliports that can be minimized through procedures for proper notification or visual warning to pilots. Examples of hazards include but are not limited to:
(1)Perforating operations: subpara-graph f.
(2)H2S gas presence: subparagraph g.
(3)Gas venting: subparagraph h; or,
(4)Closed helidecks or heliports: sub. paragraph i (unspecified cause).
(b)These and other operational hazards are currently minimized through timely dissemination of a written Notice to Airmen (NOTAM) for pilots by helicopter companies and operators. A NOTAM provides a written description of the hazard, time and duration of occurrence, and other pertinent informa-tion. ANY POTENTIAL HAZARD should be communicated to helicopter operators or company aviation departments as early as possible to allow the NOTAM to be activated.
(c)To supplement the existing NOTAM procedure and further assist in reducing these hazards, a standardized visual signal(s) on the helideck/heliport will provide a positive indication to an approaching helicopter of the status of the landing area. Recommended Practice(s) have been developed to reinforce the NOTAM procedures and standardize visual signals.
f.Drilling Rig Perforating Operations: Helideck/Heliport Operational Hazard Warning(s)/Procedure(s)1. Background. A critical step in the oil well completion process is perforation, which involves the use of explosive charges in the drill pipe to open the pipe to oil or gas deposits. Explosive charges used in conjunction with perforation operations offshore can potentially be prematurely detonated by radio
10.2.2 Special Operations
transmissions, including those from helicopters. The following practices are recommended.
2. Recommended Practices
(a)Personnel Conducting Perforating Operations. Whenever perforating operations are scheduled and operators are concerned that radio transmissions from helicopters in the vicinity may jeopardize the operation, personnel conducting perforating operations should take the following precautionary measures:
(1)Notify company aviation departments, helicopter operators or bases, and nearby manned platforms of the pending perforation operation so the Notice to Airmen (NOTAM) system can be activated for the perforation operation and the temporary helideck closure.
(2)Close the deck and make the radio warning clearly visible to passing pilots, install a temporary marking (described in subpara-graph 10.2.1i1(b)) with the words “NO RADIO” stenciled in red on the legs of the diagonals. The letters should be 24 inches high and 12 inches wide. (See FIG 10.2.1.)(3)The marker should be installed during the time that charges may be affected by radio transmissions.
(b) Pilots
(1)Pilots when operating within 1,000 feet of a known perforation operation or observing the white X with red “NO RADIO” warning indicating perforation operations are underway will avoid radio transmissions from or near the helideck (within 1,000 feet) and will not land on the deck if the X is present. In addition to communications radios, radio transmissions are also emitted by aircraft radar,
transponders, radar altimeters, and DME equipment, and ELTs.
(2)Whenever possible, make radio calls to the platform being approached or to the Flight Following Communications Center at least one mile out on approach. Ensure all communications are complete outside the 1,000 foot hazard distance. If no response is received, or if the platform is not radio equipped, further radio transmissions should not be made until visual contact with the deck indicates it is open for operation (no white “X”).
