“潮高4.8米，風力2級，現(xiàn)場條件滿足下水作業(yè)要求，可以下水！”隨著現(xiàn)場指揮的一聲令下，在山東港口裝備集團華海基地，伴著漫天雪花，一座巨大的、披著黃色外衣的矩形網(wǎng)箱乘坐著數(shù)只由青島永泰船舶用品有限公司生產(chǎn)的船舶上排下水專用氣囊平穩(wěn)滑入海中。它就是山東港口研發(fā)制造的首座深遠海養(yǎng)殖網(wǎng)箱“財金海上糧倉壹號—1”。



“財金海上糧倉壹號—1”的成功氣囊下水，是山東港口全面落實山東省委、省政府“海洋強省”戰(zhàn)略部署要求，積極開拓深遠海養(yǎng)殖裝備市場業(yè)務發(fā)展的重要標志；是對深海漁業(yè)養(yǎng)殖高質量發(fā)展的有力支持，對于提升海洋經(jīng)濟的發(fā)展水平，增強海洋綜合實力，以及推進生態(tài)文明建設等方面都具有積極的推動作用。


“財金海上糧倉壹號—1”總長89米，寬45.5米，高度35.9米，具備自身升降控制能力，可在近海海域拖航移動，便于在指定海域進行維護保養(yǎng)。網(wǎng)箱設置液位遙測系統(tǒng)和環(huán)境監(jiān)測系統(tǒng)，具備液位高低報警、飼料投喂、能源供給，以及海域水溫、溶解氧等水文參數(shù)監(jiān)測功能，可以實現(xiàn)深海養(yǎng)殖無人值守。正式投產(chǎn)運營后，可以有效解決傳統(tǒng)海上養(yǎng)殖裝備抗風浪性能低、人工喂養(yǎng)成本高、養(yǎng)殖作業(yè)效率低等發(fā)展痛點，實現(xiàn)深海漁業(yè)養(yǎng)殖生產(chǎn)的集約化、智能化。


作為山東港口首次建造的深遠海養(yǎng)殖網(wǎng)箱，制造難度大、智慧化程度高。為了順利完成網(wǎng)箱的研發(fā)制造，裝備集團高度重視，組織精干力量成立攻堅團隊，克服惡劣天氣、技術難關等一系列問題。300余名鐵軍將士錨定下水目標，日夜奮戰(zhàn)，以驚人的毅力、不屈不撓的精神順利完成氣囊下水任務。


本次網(wǎng)箱的成功氣囊下水，離不開日照港、港灣建設集團的鼎力支持，“嵐港拖18”“日港拖26”“日港工拖26”等船舶為“財金海上糧倉壹號—1”下水保駕護航。用自家建造的船舶為自家研發(fā)建造的首座網(wǎng)箱完成氣囊下水任務，彰顯裝備集團出色的研發(fā)制造能力和山東港口各直屬單位握指成拳的融合力量。

On the morning of January 16, 2024, at 8:30 AM, EVERSAFE MARINE successfully launched a 3000-ton deep-sea aquaculture cage in Rizhao City, Shandong Province, using airbag ship launching technology. The cage, named “Sea Granary One,” is a fully submersible deep-sea salmon farming cluster cage. It measures 89 meters in length, 45 meters in width, and 32 meters in height, with a launch weight of 3000 tons. The cage features a fully submersible rigid cage structure, with a maximum aquaculture water capacity of 40,000 cubic meters, and an estimated annual production of over 1300 tons of salmon.

The construction of the cage was completed by Shandong Port Equipment Group Co., Ltd., and the launching ramp was made of cement, divided into two sections. The above-water slope is 1/70, and the underwater slope is 1/20. EVERSAFE MARINE utilized 42 high-strength marine airbags arranged in two rows for the launch.

The airbag cage launching process consists of three steps:

1- lifting the cage with airbags and removing the supports,

2- moving the cage to the water’s edge on the launch platform,

3- launching the cage into the water at high tide.

During the lifting process, the cage is secured with a winch, and airbags are inserted between the supports at the bottom of the cage. When the airbags are inflated to 0.15 MPa, the cage leaves the supports, and the supports are removed. Controlled by the winch, the cage moves 120 meters until it reaches the water. At high tide, the winch releases the steel wire rope, allowing the cage to smoothly enter the water with the rolling airbags.

With the continuous development of ocean ranching technologies and policy guidance, modern ocean ranches are gradually moving towards the “deep-sea” direction. The deep-sea aquaculture cages built in China are increasing in volume and weight. Using airbag launching technology can shorten the construction cycle of site foundations and save a considerable amount of funds. EVERSAFE MARINE, as a specialist company in airbag engineering, takes pride in contributing to the economic development of China in various fields.
