Anchored by Standards, Securing Our Position in the Deep‑Blue Ocean; Rooted in Technology, Building the Blue Granary.

Recently, Qingdao Qihang Fishing Cage Co., Ltd. convened an internal‑and‑external expert review meeting for its corporate standard Technical Specification for Design and Construction of Mooring Systems for HDPE Floating Aquaculture Facilities (Q/QHCZ 002—2026). Following rigorous internal deliberation and authoritative demonstration by external experts, the standard successfully passed review. This marks a key phased achievement for Qingdao Qihang Fishing Cage Co., Ltd. in advancing the standardisation and normalisation of mooring systems for HDPE floating aquaculture facilities.

As a corporate standard of Qingdao Qihang Fishing Cage Co., Ltd., this document targets floating aquaculture facilities predominantly made of HDPE (High‑Density Polyethylene). It applies to gravity‑driven circular cages, gravity‑driven square cages, aquaculture monitoring platforms and other installations, covering marine waters, freshwater lakes, reservoirs, inland rivers and other water bodies. Centring on the design and construction of mooring systems, the standard specifies technical requirements for critical links including load calculation and design operating conditions, providing unified technical basis for the company’s product design, construction organisation and quality control. The formulation of this standard represents an important initiative by Qingdao Qihang Fishing Cage Co., Ltd. to serve the Maritime Power Strategy and promote the high‑quality development of modern marine fisheries. It also embodies the company’s conscious pursuit and mission: demanding higher benchmarks for itself, refining product quality with stricter requirements, and driving industry progress with greater responsibility.

The internal review meeting was hosted by Qingdao Qihang Fishing Cage Co., Ltd., with participation from relevant management and technical staff. Reviews focused on the standard’s framework, technical routes, content completeness, engineering operability and compatibility with the company’s existing technical system. Participants concluded that the standard features systematic and comprehensive content with strong pertinence and practical operability, offering vital guidance for corporate product design and construction organisation. The internal review approved the standard for passage, while putting forward revision suggestions concerning textual rigour, applicability of technical parameters and construction requirements.

Building upon the internal review, the company held a separate external expert review meeting. Invited reviewers included Researcher Guan Changtao and Associate Researcher Wang Gang from the Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, as well as Professor Song Xiefa from the College of Fisheries, Ocean University of China. During the review session, the drafting group presented the background, formulation principles, core technical content and follow‑up work plan of the standard. Experts examined the standard document and submitted revisions and suggestions regarding textual preciseness, suitability of technical parameters and construction practicality. The expert panel affirmed that the standard is necessary and timely, with rational structural framework and systematic technical content. It delivers positive guidance for the design and construction of mooring systems for HDPE floating aquaculture facilities and was approved for adoption.

The formulation and successful review of this standard carry far‑reaching significance. By standardised approaches, it enhances the safety of HDPE floating aquaculture facility mooring systems under complex operating conditions and mitigates risks of facility drift and secondary accidents. Through standardised workflows, it facilitates the transition of mooring‑system design and construction from experience‑driven practice to formal standardised management, lifting product quality and engineering service capabilities. Guided by systematic thinking, it supports deep‑sea aquaculture development, the construction of the Blue Granary and industrial technological advancement, thereby laying solid support for the high‑quality growth of modern marine fisheries.

Moving forward, Qingdao Qihang Fishing Cage Co., Ltd. will sort out, analyse thoroughly and fully incorporate comments raised in both internal and external expert reviews, further optimise the standard text, and advance subsequent procedures in compliance with formal protocols.

Striving for Maritime Strength with Standards at the Forefront. Taking this standard‑setting work as an opportunity, Qingdao Qihang Fishing Cage Co., Ltd. will continue refining its corporate standard system, strengthening technological innovation and engineering practice, contributing to the safe, eco‑friendly and high‑quality development of China’s modern marine fisheries, and composing more substantial chapters for Qihang amid the grand endeavour of building a maritime power.
