Summary
This study introduces standardized design and calculation methods for suction drum foundations in China, addressing current subjective practices. Verified with real-world offshore wind projects, these methods improve engineering reliability.
Area of Science:
- Geotechnical Engineering
- Offshore Engineering
- Foundation Design
Background:
- Lack of standardized design and calculation specifications for suction drum foundations in China.
- Current engineering design relies heavily on subjective designer experience, leading to potential inefficiencies.
- Need for systematic research to address these limitations in offshore wind projects.
Purpose of the Study:
- To develop and validate a systematic approach for the design calculation and construction control of suction drum foundations.
- To propose a sinking feasibility analysis method and a parameter value method for foundation calculations.
- To provide reliable references for similar foundation designs and constructions.
Main Methods:
- Systematic study integrating domestic and international research, design specifications, and engineering applications.
- Development of a sinking feasibility analysis method and a parameter value method for suction drum foundation calculations.
- Examination of construction process control parameters, technology, and standards, validated with field data.
Main Results:

01:19Design Example: Maintaining Level of an Embankment
68
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

01:14Design Example: Managing Concrete Workability
81
This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.

99
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...

01:13Pumped Concrete
70
Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...

01:22Design Consideration
187
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
