Technical Specs & Approval

Hangzhou Star Marine Technology Co., Ltd. – High Holding Power Anchor Technical Specifications

Hangzhou Star Marine Technology Co., Ltd. designs and manufactures High Holding Power (HHP) anchors to stringent international maritime standards, ensuring optimal seabed penetration, resistance to dragging, and long-term reliability across diverse operational environments. Our HHP anchors, compliant with ISO 15792:2018 for shipboard anchor equipment, represent a significant advancement over traditional stockless designs, offering superior holding characteristics essential for vessel safety in demanding conditions. The technical parameters detailed below reflect our commitment to engineering excellence and adherence to classification society requirements, including DNV, LR, ABS, and CCS. Precise specification selection is critical and must align with vessel size, operational profile, and anticipated seabed composition.

Material Grade Certification
All Hangzhou Star HHP anchors are manufactured from high-tensile steel meeting rigorous marine-grade specifications. The U2 grade utilizes steel conforming to ISO 4990:2015 Grade B or equivalent, suitable for general commercial vessel applications where ultimate strength requirements are defined by standard classification rules. The U3 grade employs ultra-high-strength steel per ISO 4990:2015 Grade D or superior equivalents, specifically engineered for vessels operating in extreme environments, ice-infested waters, or where enhanced structural integrity under maximum load is paramount. Both grades undergo full material traceability and comprehensive mechanical testing, including tensile strength, yield point, elongation, and impact toughness verification at sub-zero temperatures as required.

Weight and Holding Power Performance
Anchor weight is precisely calculated based on the vessel’s displacement and windage area, following standard classification society rules. Hangzhou Star HHP anchors deliver exceptional holding power relative to their mass. The U2 grade achieves a minimum holding power to weight ratio of 50:1 in medium-density sandy seabeds under controlled ISO 15792 testing conditions. The U3 grade exceeds this benchmark, consistently demonstrating ratios of 60:1 or higher in identical test scenarios, attributable to its optimized fluke geometry, shank profile, and increased structural robustness. This superior performance translates directly to reduced anchor weight requirements for equivalent holding capacity compared to conventional designs, offering potential vessel weight savings.

Surface Treatment and Corrosion Protection
To ensure longevity in aggressive marine environments, all Hangzhou Star HHP anchors receive a comprehensive corrosion protection system. The primary treatment is hot-dip galvanizing per ISO 1461, providing a minimum zinc coating thickness of 80µm on all critical surfaces. For vessels requiring extended service life or operation in highly corrosive waters, an optional duplex system is available, combining the hot-dip galvanized base with a topcoat of high-performance epoxy marine paint meeting ISO 12944 C5-M requirements. All surface preparation adheres strictly to Sa 2.5 (ISO 8501-1) standards prior to coating application, guaranteeing optimal adhesion and protection integrity.

The following table summarizes the key technical parameters for Hangzhou Star’s standard HHP anchor offerings:

Note: Holding power ratios are determined under controlled laboratory conditions per ISO 15792 Annex A using medium-density sand. Actual in-service performance varies with seabed type, scope of rode, and deployment technique. Weight ranges are indicative; specific anchor mass is determined by vessel particulars and classification society rules.
