CFD simulations for Offshore, tugs & dredgers
How offshore service vessels operate in demanding conditions
Offshore tugs, anchor-handlers, and dredgers face extreme operational demands—from bollard pulling heavy loads to navigating shallow waters safely. VICUSdt applies CFD simulations for offshore tugs and dredgers to model and optimize these complex operations before they hit the water. Whether refining tug bollard pull performance, enhancing dredger hull form for shallow-water operations, or troubleshooting tow-vibration issues in pushers, our CFD-driven engineering ensures reliable performance, saving time, cost, and avoiding surprises during sea trials. Advanced analysis equips designers and operators with actionable insights to maximize safety and operational efficiency.
Types of offshore service vessels and their specific functions
The category of offshore service vessels covers a wide range of ship types, each designed for specialized operations that support the maritime and energy industries. Mechanical dredgers are essential for maintaining navigable waterways, port construction, and seabed preparation, using robust equipment to remove sediments with precision and efficiency. In contrast, naval tugs are primarily deployed to assist military fleets, providing towing, escorting, and maneuvering capabilities in demanding naval environments where reliability and power are crucial.
On the commercial side, ocean tug boats play a vital role in towing large vessels, offshore platforms, and heavy equipment across long distances, often under challenging sea conditions. Their design emphasizes endurance, bollard pull, and advanced propulsion systems to ensure safe and effective operations. Beyond these, offshore service vessels can also include anchor-handling tug supply ships, multipurpose support vessels, and specialized dredgers, all contributing to efficient offshore logistics and marine construction.
By applying advanced CFD simulations and propulsion optimization, VICUSdt helps shipyards, owners, and operators enhance the performance of each vessel type—reducing fuel consumption, improving maneuverability, and extending the operational lifespan of these mission-critical assets.
Project examples with dredgers, tugboats and offshore vessels:
- Seakeeping analysis of Crew Transfer Vessel: We simulate wave-induced motions and accelerations to optimize hull lines, ensuring safe and comfortable transfers under harsh sea states.
- Bollard pull optimization of a 200 TBP AHT: Using CFD, we accurately model tug thrust vs. resistance, enabling us to enhance bollard pull performance for anchor-handling tugs (e.g. 200 TBP) while minimizing fuel usage.
- Shallow-Water Hull optimization for dredgers: CFD evaluates hull resistance and power demand in limited-depth operations, reducing risk and improving fuel efficiency.
- Thruster Design and supply for offshore service vessels: We design and supply main thrusters optimized for vessel type and duty cycle, maximizing efficiency and responsiveness.
- Tow-Pull & Vibration Troubleshooting: CFD helps diagnose and mitigate tow-induced vibrations in pushers, improving structural longevity and crew safety.
- Wake Flow & Gondola Analysis: For specialized offshore service vessels, we analyze streamline flow around deep hull appendages or oceanographic gondolas to refine design and reduce resistance.
