Description

Technical Field

[0001] This invention belongs to the field of helicopter deck technology, and particularly relates to a platform steel helicopter deck with anti-slip protection. Background Technology

[0002] Helicopter decks are extremely important for offshore platforms. Unmanned platforms typically have separate helicopter decks made of aluminum alloy and equipped with safety nets. However, current technology still has the following problems: 1. For unmanned marine wellhead platforms, the helicopter deck is usually set up separately. Its auxiliary support system increases the amount of structural engineering, affects the construction period, and accounts for a high proportion of the cost.

[0003] 2. To ensure the lightweight design of helicopter decks, they are generally made of aluminum alloy. However, from a cost perspective, the deck and the equipment bases on the deck are generally made of steel. If the helicopter deck is also used as the upper deck, there is a problem that dissimilar metals cannot be welded together.

[0004] 3. When the platform fire protection system adopts the Integrated Deck Fire Protection System (DIFFS), the traditional landing net can no longer be used on the helicopter deck for anti-slip measures.

[0005] Therefore, there is an urgent need to design a platform steel helicopter deck with anti-slip protection to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a platform steel helicopter deck with anti-slip protection, which has the advantages of lightweight design and long-lasting anti-slip protection technology, and solves the problems involved in the background art.

[0007] To achieve the above objectives, the specific technical solution of the steel helicopter deck with anti-slip protection of the present invention is as follows: A platform steel helicopter deck with anti-slip protection is provided, which directly connects the platform steel helicopter deck to the upper deck. It includes a landing center and a water-retaining dike. The water-retaining dike is set between the landing center and the first upper deck area. A landing ring is set around the landing center, and mooring points are connected to the landing ring to enable the helicopter to take off or land. The surface of the landing center is coated with anti-slip paint to provide long-term anti-slip protection.

[0008] Furthermore, the landing center is located in the second upper deck area, which is situated to one side of the first upper deck area.

[0009] Furthermore, a water-retaining dike is provided between the first upper deck area and the second upper deck area to prevent helicopter oil leaks from the second upper deck area from entering the first upper deck area.

[0010] Furthermore, the maximum overall length of the helicopter rotor during rotation shall not exceed the width of the second upper deck area.

[0011] Furthermore, drainage channels are provided along the edge of the second upper deck area circumferentially from the land center to allow rainwater and fuel spills to be discharged in a directional manner along the drainage channels.

[0012] Furthermore, the drainage trough is located far from the landing center and is equipped with a safety net.

[0013] Furthermore, several barrier-free areas are set up along the safety net away from the landing center to avoid affecting helicopter take-off and landing.

[0014] Furthermore, the first upper deck area is divided into a wellhead area, a first equipment area, and a second equipment area.

[0015] Furthermore, the first equipment area and the second equipment area are spaced apart on both sides of the wellhead area.

[0016] Furthermore, the second upper deck area is equipped with an integrated fire suppression system to handle helicopter oil leaks or fires.

[0017] The steel helicopter deck with anti-slip protection of the platform of the present invention has the following advantages: By integrating the platform steel helicopter deck with the upper deck into a lightweight design and employing long-lasting anti-slip technology, this invention saves time and costs, reduces design and construction workload, and ensures the long-term safe operation of the new deck system. This application guarantees a lightweight design for the helicopter deck, reduces construction costs, and ensures the anti-slip effect of the platform steel helicopter deck.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0022] The following is a reference to the appendix. Figure 1 The present invention describes a platform steel helicopter deck with anti-slip protection.

[0023] like Figure 1 As shown, the anti-slip platform steel helicopter deck of the present invention directly connects the platform steel helicopter deck to the upper deck. It is characterized by including a landing center 1 and a water-retaining cofferdam 2. The water-retaining cofferdam 2 is set between the landing center 1 and the first upper deck area 3. A landing ring 5 is set around the landing center 1, and a mooring point 6 is connected to the landing ring 5 to enable the helicopter to take off or land. The surface of the landing center 1 is coated with anti-slip paint to make the landing center 1 anti-slip for a long time.

[0024] By integrating the platform's steel helicopter deck with the upper deck into a lightweight design and employing long-term anti-slip technology, the project aims to save time and costs, reduce design and construction workload, and ensure the long-term safe operation of the new deck system.

[0025] Furthermore, such as Figure 1 As shown, the landing center 1 is located in the second upper deck area 4, which is located on one side of the first upper deck area 3. A water-blocking dike 2 is provided between the first upper deck area 3 and the second upper deck area 4 to prevent helicopter oil leakage from the second upper deck area 4 into the first upper deck area 3.

[0026] Meanwhile, it is necessary to ensure that the maximum total length of the helicopter rotor when it is rotating does not exceed the width of the second upper deck area 4; the second upper deck area 4 is equipped with an integrated fire protection system to deal with helicopter oil leaks.

[0027] Furthermore, such as Figure 1 As shown, a drainage channel 8 is provided along the land center 1 and on the second upper deck area 4. That is, the direct drainage channel 8 is provided at the perimeter 7 of the elevator deck so that rainwater can be discharged in a directional manner along the drainage channel 8.

[0028] The drainage channel 8 is equipped with a safety net 9 on the side away from the landing center 1, and multiple unobstructed areas 10 are provided along the side of the safety net 9 away from the landing center 1 to avoid affecting the take-off and landing of helicopters; that is, within the 210° unobstructed fan area of ​​the second upper deck area, the height of any obstacle shall not exceed 250mm.

[0029] Furthermore, such as Figure 1 As shown, the first upper deck area 3 is provided with a wellhead area 11, a first equipment area 12 and a second equipment area 13; preferably, the first equipment area 12 and the second equipment area 13 are arranged alternately on both sides of the wellhead area 11, and it is necessary to ensure that the design height of the wellhead area 11, the first equipment area 12 and the second equipment area 13 is sloped at a ratio of 1:2 along the 150° fan-shaped surface on the left side of the second upper deck area.

[0030] Based on a platform steel helicopter deck with anti-slip features, this invention not only ensures a lightweight design for the helicopter deck but also reduces construction costs and guarantees the anti-slip performance of the platform steel helicopter deck. The integrated deck resolves the prominent contradiction between the structural strength of the equipment area and the high anti-skid performance of the helicopter take-off and landing area. It not only avoids the risk of galvanic corrosion caused by dissimilar metal connections, but also significantly reduces construction costs, providing a reliable technical solution for the functional integration of similar platforms.

[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
