Scope

GB/T 47043-2026 is the English-translated version of 船舶和海上技术　固定结构冰载荷模型试验.

GB/T 47043-2026 is the Chinese standard "Ships and marine technology - Model tests of ice loads on fixed structures". Its scope clause reads: This document specifies the test conditions and operating parameters, test instruments and equipment, and test requirements for ice load model tests on fixed marine structures.

Requirements, experimental procedures, experimental data acquisition and processing, and experimental reports. This document applies to ice load model tests on stationary marine structures affected by sea ice.

Ice load model tests are typically conducted in ice-water tanks. This is for reference and use in ice load model tests conducted in non-ice water pools. Its clauses include terms and definitions.

1 Scope

This document specifies the test conditions and operating parameters, test instruments and equipment, and test requirements for ice load model tests on fixed marine structures.

Requirements, experimental procedures, experimental data acquisition and processing, and experimental reports.

This document applies to ice load model tests on stationary marine structures affected by sea ice. Ice load model tests are typically conducted in ice-water tanks.

This is for reference and use in ice load model tests conducted in non-ice water pools.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 fixed structure

Connected to the seabed via pile foundations, gravity foundations, or other fixing methods, it maintains its position throughout its service life and is used for oil and gas production.

Structures for offshore operations such as production, wind power generation, and port protection.

Note. Fixed structures in this document include, but are not limited to, jacket platforms, gravity platforms, and fixed offshore wind power foundations.

3.2 icemodeltest

Scaled-down physical simulation experiments used to study the interaction process between ice and structures and to observe key physical parameters.

3.3 ice tank; icebasin

A low-temperature testing facility used to simulate ice-water environment conditions and conduct ice model tests under controlled conditions.

3.4 Model Ice

An experiment to simulate the physical and mechanical properties of natural ice, which involves freezing a specifically proportioned aqueous solution in an ice-water tank through a controlled process.

medium.

3.5 boundary effect

The phenomena or changes related to the boundary caused by the existence of the boundary of an object or system.

Note. Boundary effects in ice model tests are usually caused by the pool wall or the free end of the ice floe.
