Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, in particular to an optimization system for a ship helicopter hovering platform. Background Art

[0002] Due to their unique safety, practicality, and efficiency, helicopters are now widely used on various types of ships and platforms at sea. Ship-based helicopter operations primarily include landing and hovering. During offshore oil transportation, tankers often require helicopter hover platforms for takeoff and landing. Traditional deck-mounted helicopter hover platforms can have design and layout deficiencies, such as exposed cargo hold reinforcements, low deck space utilization, poor coordination with other tanker equipment, and unclear helicopter markings. These issues can affect safe helicopter takeoff and landing, as well as operational efficiency.

[0003] On tankers currently on the mainstream market, most helicopter hovering markings are applied directly to the deck using a bead welding process. However, if the cargo deck reinforcement is exposed on the main deck, the markings cannot be properly arranged due to the presence of the cargo deck T-section, which prevents continuous welding. When the cargo deck keel or reinforcement is exposed on the deck, the helicopter rescue helicopter cannot clearly see the hovering position on the ship. The crew in the bridge also cannot directly see the hovering mark. Therefore, both the ship rescue team and the helicopter cannot directly and quickly find the hovering mark, resulting in delayed helicopter rescue. Summary of the Invention

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a ship helicopter hovering platform optimization system, which solves the problem of helicopter marking arrangement when the deck surface reinforcement ribs are exposed, and the problem that the helicopter marking cannot be correctly welded to the deck surface, solves the rationality of the spatial layout, enhances the coordination between the deck surface outfitting parts of the tanker, and optimizes the maintenance channel and safety of the helicopter.

Example 1

[0029] See also Figures 1-6 , Figure 1 A schematic diagram of the structure of the present invention is provided. As shown in the figure, the present invention relates to an optimized system for a ship's helicopter hovering platform. It includes a helicopter hovering platform, a navigation lighting system, and a maintenance access route, located in the bow area of the main deck. This avoids exposed areas of the deck keel or reinforcement. The navigation lighting system is located on one side of the helicopter hovering platform, and the maintenance access route is located on the other side of the platform.

[0030] The helicopter hovering elevated platform includes a hovering platform 1, a plurality of supporting angle steels 2 are arranged below the hovering platform 1, a parallel frame 3 arranged parallel to the hovering platform 1 is provided below the supporting angle steels 2, and a plurality of connecting rods 4 distributed in a grid are provided in the parallel frame 3 to increase the support of the parallel frame 3.

[0031] The edge of the hovering platform 1 is provided with a circle of supporting angle steel 2, the top end of which is vertically connected to the edge of the hovering platform 1, and the bottom end is vertically arranged on the parallel frame 3;

[0032] In addition to a circle of supporting angle steels 2 set on the edge of the hovering platform 1, at least four supporting angle steels 2 are set below the bottom surface of the hovering platform 1. The top ends of these supporting angle steels 2 are vertically connected to the bottom surface of the hovering platform 1, and the bottom ends are vertically set on the connecting rods 4, preferably on the connection intersection of the connecting rods 4.

[0033] A plurality of support rods 5 are provided below the parallel frame 3 and are arranged on the main deck through the support rods 5 ; triangular reinforcement plates 6 are provided at the connection between the support rods 5 and the parallel frame 3 for increasing the support strength.

[0034] The main deck is also provided with an auxiliary area, which is arranged at the edge of the deck or in an idle area. The auxiliary area can be a personnel assembly area, an evacuation area, etc.

[0035] The navigation lighting system includes at least two floodlights 7, which are arranged on the same side of the helicopter hovering elevated platform. The height of the lamp mast of the floodlight 7 is higher than the height of the hovering platform 1. The lighting range of the floodlight 7 covers the entire hovering platform 1 to ensure that the helicopter platform has sufficient lighting.

[0036] The maintenance passage utilizes the original walkway passage 8 on the main deck, and at least one walkway branch 9 is extended from the side of the walkway passage 8 close to the hovering platform 1. The walkway branch 9 leads to the hovering platform 1. An inclined ladder 10 is set between the walkway branch 9 and the hovering platform 1 to facilitate daily maintenance and inspection of the platform and to facilitate the later transportation of the wounded to the helicopter.

[0037] In this embodiment, the hovering platform 1 is made of a regular hexagonal steel plate, and the parallel frame 3 is made of a hexagonal steel pipe frame that is parallel to the hovering platform 1; the size of the hovering platform 1 ensures that the helicopter can hover without affecting the normal operation of other equipment on the tanker.

[0038] Working principle:

[0039] The utility model provides a ship helicopter hovering platform optimization system, which uses the following aspects for layout optimization:

[0040] (1) Optimized space layout: Based on the tanker deck reinforcement, such as the exposed main deck and the helicopter model, a helicopter hovering elevated platform (at the WINCH ONLY mark) is planned in the bow area of the main deck as shown in Figure (1). Ensure that the platform area is large enough and does not affect the normal operation of other equipment on the tanker. At the same time, auxiliary areas such as personnel assembly areas are set up on the edge of the deck or in the vacant area to improve space utilization.

[0041] (2) Enhance coordination: During the layout process, full consideration should be given to the coordination between the helicopter hovering platform and other equipment on the tanker, such as the oil tank vent mast, the height of the small hatch cover and the height of the gangway, to avoid mutual interference. For equipment that may cause conflict, measures such as shifting, shielding or adjusting the height should be taken. For example, the ballast water pipes arranged on the deck surface need to give way to the helicopter hovering area, and the ballast water pipes need to pass under the helicopter platform. The ballast water pipes must not be higher than the helicopter hovering platform to ensure the safety of the helicopter during take-off and landing.

[0042] (3) Clear signs and lighting: Set up eye-catching signs and navigation lighting systems on the helicopter hovering platform. The lighting system is mainly based on the floodlights on the mast. The lighting range needs to cover the entire helicopter platform. The floodlight mast needs to be higher than the helicopter platform to ensure that the helicopter platform has sufficient lighting to assist the helicopter to take off and land safely at night or in low visibility conditions. At the same time, ensure the clarity and visibility of the signs and lighting facilities to improve the recognition of helicopter pilots.

[0043] (4) Optimize maintenance channels: Set up reasonable maintenance channels around the platform. Taking a 75,000 DWT tanker as an example, a branch of the main deck walkway is opened, and then the helicopter hovering platform is directly reached through an inclined ladder, which is convenient for daily maintenance and overhaul of the platform, and convenient for the transportation of injured people to the helicopter in the later stage, thereby improving the rescue efficiency. At the same time, the safety of the helicopter during take-off and landing is improved through clear signs, lighting facilities, guardrails and other measures.

[0044] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
