Engineering
TWD marine engineers provide solid support to help your marine equipment realize transport and installation projects successfully. Our multidisciplinary teams allow us to involve the right experts at the right time to minimize your project risks and develop cost-efficient solutions.
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 develop custom-made solutions to run complex marine operations efficiently and to finalize your project with optimal results.
Do you want to explore how TWD applies marine engineering expertise in critical areas such as motion, stability, dynamic analyses, mooring system designs, and innovative mission equipment? In this booklet, you can find insights into some of our exciting projects and discover how we can support your next venture.
Our Expertise
Our marine engineers specialize in conducting various motion
analyses. We determine wave-induced motions and accelerations for all types of structures serving as input to your mission equipment and seafastening design.
Due to our extensive experience, we can perform diffraction-based motion analysis in short lead times. Furthermore, by applying our diverse knowledge, 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
Among our services, we offer comprehensive workability analyses for a range of offshore operations. These operations include pile installation, (floating) lifts through the splash zone, cable laying and other offshore operations.
Through the analysis, our engineers are able to:
- Lay out all the operational limitations (e.g. maximum allowable
significant wave height) to lead to the safest and most time-efficient operations - Help equipment designers create mitigations that improve
workability - Advise on alternative and more efficient installation methods
Workability Analysis
Our marine engineers use both commercial software and in-house developed tools to make stability analysis and ballasting plans.
We provide these services 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

Stability Analysis & Ballasting Plans
Safeguarding the position of barges or vessels is of high importance for an efficient marine operation. Our 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 DNV bollard pull calculations - Selecting the most suitable mooring equipment to perform quay or offshore moorings
Mooring Analysis & Bollard Pull Calculations
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.
Design and Operational Support
We offer full operational support beyond marine engineering. For example, throughout the execution of your installation, construction, or transportation project, we can assist with the mobilization and utilization of our designs. This way, we continuously optimize the workability and cycle time of your offshore project. In addition, by monitoring the operation and using our in-depth understanding of the designs, our field engineers can work out design solutions or quick fixes to improve your operation on the spot. Our full operational support covers Method Engineering, Structural and Mechanical Engineering and Design, Geotechnical Engineering, Fabrication Management, and Field Engineering.
