At TWD, our marine engineers can provide you with solid support to help your marine equipment successfully realize transport and installation projects.
Working in marine environments can bring many challenges to your project. To tackle these challenges, our dedicated marine engineers conduct solid analyses so that your equipment can be operated safely and with maximal workability. Our in-house experience with automation tools, combined with specialist marine software packages, enables us to efficiently run complex projects. Since we have multiple disciplines under one roof, we can involve the right experts at the right time to minimize your project risks and develop tailor-made cost-efficient operational plans just for you.
Our Expertise
Motion Analysis
TWD's engineers are specialized in conducting various motion analyses. We know how to determine wave-induced motions and accelerations for all types of structures: floating, sailing or submerged.
Thanks to our extensive experience, we can perform diffraction-based motion analysis in short lead times. Furthermore, applying our diverse expertise, we can help you with floating structures, such as:
- Vessels and barges
- Buoys and moored structures
- Caissons and other floating gravity-based structures
Motion Analysis
Workability Analysis
We conduct workability analyses for various offshore operations. These operations include pipeline or cable installation, (floating) lifts through the splash zone to the seafloor, and other barge or vessel operations.
Through our analysis, our engineers can:
- Help equipment designers create mitigations that improve workability
- Advise you on alternative and more efficient installation methods
- Lay out all the operational limitations (e.g. maximum allowable significant wave height) to lead to the safest and most time-efficient operations
Workability Analysis
Stability Analysis & Ballasting Plans
Our marine engineers use both GHS software and in-house developed tools to make stability analysis and ballasting plans. We are competent in providing these for a wide range of vessels and floating structures, such as jack-ups, ships, and barges.
Specifically, we can support you with:
- Performing intact and damage stability analyses for class and authority approval
- Creating stability booklets, inclining tests, and lightweight surveys
- Determining ballast plans and ballasting sequences for your SPMT loadouts, lifting operations, and semi-submersible operations
- Creating detailed and clear reports for the Marine Warranty Survey

Safeguarding the position of barges or vessels is of high importance for an efficient marine operation. TWD’s marine engineers have the know-how in the design and analysis of catenary and quay mooring systems. We utilize this knowledge to assist you with:
- Vessel mooring analyses through applying quasi-static or fully dynamic analysis solutions
- Selecting the most suitable tug to perform a towing operation based on our solid bollard pull calculations
- Selecting the most suitable mooring equipment to perform quay or offshore moorings

Dynamic Analysis
TWD has developed an in-depth knowledge of dynamic analysis (both mechanical and hydromechanical). By investigating how our designs will move, deflect, and vibrate under the influence of operational forces, dynamic analysis enables us to visualize the working principle of your project and study the key design parameters in detail. Based on your project specifics, our marine engineers can perform analyses either under one degree-of-freedom (DoF), multi-DoF, or even a full flexible FE analysis. We then combine the analysis input with our knowledge of structural, mechanical, actuation, and control. By doing so, we help you make proper design decisions, create simple and competitive designs, and increase the life expectancy of your temporary works.
