Qingdao Huahai Environmental Protection carried out real‑sea performance tests for oil booms in offshore waters. During the project, sea surface temperatures were low and sea winds persisted. The test team rose to the challenge and completed the full‑process offshore deployment and anti‑wave performance measurement to high standards. All equipment parameters met requirements, marking the successful completion of the offshore trial.

At the test wharf, staff worked with lifting equipment to unfurl the oil boom in an orderly manner. The orange‑red boom sections together with the underwater barrier net were deployed segment‑by‑segment. Supported by the matching electric winch system, the whole operational workflow — unwinding from reels, offshore towing and surface enclosure — was completed efficiently. Affected by offshore cold air, strong winds and frequent swells occurred during the test period, which perfectly simulated harsh sea conditions in real‑life oil spill incidents and served as the most rigorous on‑site verification of the product’s wave‑resistance performance. Under continuous wave impacts, the floaters of the oil boom remained stable on the water surface, while the underwater barrier net maintained a reliable vertical depth. No capsizing, tearing or oil leakage was observed. Both surface floating oil and sunken oily residues were effectively contained, with measured performance exceeding design specifications.

Custom‑developed for complex sea conditions in open seas and large harbours, this oil boom can contain not only surface crude oil but also semi‑submerged oily debris, addressing the limitation of conventional oil booms in handling sunken oil pollution. During the research‑and‑development phase, the technical team repeatedly optimized fabric formulations and framework structures. Low‑temperature‑resistant and seawater‑corrosion‑resistant materials were thickened, and hot‑weld joint processes were enhanced to improve weather resistance and tear resistance at the raw‑material level. The product is well‑suited for extreme operating conditions with low temperatures and heavy sea winds in northern sea areas during autumn and winter.

As a high‑tech enterprise, Huahai Environmental Protection adheres to the quality‑control principle of “dual validation by laboratory data and real‑sea field tests”. Products are never finalized based solely on laboratory data. All large‑ and medium‑scale oil‑containment equipment must undergo field trials under harsh offshore sea conditions. The full success of this test amid low temperatures and high winds further consolidates confidence for product application in projects along northern coastlines.

Moving forward, the enterprise will fine‑tune product details based on field‑test data from this offshore campaign and speed up mass production. With high‑performance equipment proven in real‑world wind‑and‑wave conditions, the company will contribute to safeguarding the marine environmental safety of China’s offshore waters.
