Marine & Offshore
Simulation Solutions for Maritime Structures, Equipment, and Fluid Systems
At ENA2, we support shipbuilders, offshore EPCs, marine system suppliers, and vessel equipment manufacturers with high-precision simulations and structural validation. Our services cover stress analysis, fluid flow, thermal behavior, and equipment fatigue—ensuring safety, durability, and compliance with marine classification standards.
Whether it’s a topside module, below-deck piping system, hull structure, or enclosed HVAC zone, we help teams identify risks early and improve designs before fabrication. From offshore platforms to seagoing vessels, ENA2 enables faster, more reliable development of marine and offshore assets—engineered to perform under wave loads, dynamic motion, saltwater exposure, and harsh operational conditions.
WHAT WE DO
At ENA2, we support shipbuilders, offshore EPCs, naval engineering teams, and marine equipment manufacturers with advanced simulations that predict how structural and mechanical systems behave under marine conditions. Whether you’re designing a fuel skid, a seawater cooling system, or accommodation HVAC for a deepwater platform, our FEA and CFD simulations help you meet safety, durability, and performance goals with confidence.
From vessel hulls and deck-mounted equipment to offshore process skids and ballast tanks, marine and offshore systems are exposed to high pressure, vibration, wave impact, and harsh environments. These systems must be engineered for strength, stability, and compliance with marine classification standards—while remaining lightweight, efficient, and cost-effective to build and maintain.
HOW WE DO IT
Marine structures and onboard systems face a complex combination of forces: static loads from cargo or equipment, dynamic motion from waves, internal pressure from fluids, and thermal stress from engines and environmental variation. At ENA2, we replicate these interactions in virtual simulations using Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD).
Our engineering simulations allow teams to:
- Reduce material use while ensuring safety under marine codes (DNV, ABS, IMO, etc.)
- Prevent failure due to fatigue, vibration, or pressure cycling
- Optimize fluid handling and air management in enclosed vessel systems
- Support inspection, maintenance, and retrofit with better lifecycle predictions

Structural Stress Analysis of Hulls, Frames, and Deck Equipment
We simulate the structural performance of vessel hulls, support beams, bulkheads, and deck-mounted skids under wave impact, dynamic loading, and transport conditions. Using FEA, we assess fatigue risk in crane foundations, lift points, engine mounts, and container supports—all subject to harsh loading from ship motion and equipment cycles.
For offshore structures, we evaluate jacket foundations, braces, and structural connectors under combined wind, wave, and deck load conditions. Our simulations also support structural optimization—minimizing weight while ensuring compliance with applicable marine safety codes and load case requirements.
Equipment, Tanks, and Welded Structure Optimization
We perform detailed stress analysis on fuel tanks, ballast systems, pressure vessels, and storage enclosures for marine service. Using nonlinear and thermal-stress simulations, we verify structural strength under internal pressure, thermal gradients, and slosh dynamics.
We also simulate fabrication effects, such as welding-induced stress, thermal distortion, and sheet metal forming, to support better planning, assembly, and long-term durability. Our simulations help manufacturers design for resistance to corrosion fatigue, vibration, and repeated loading in saltwater environments.


Fluid Flow and Pressure Control in Marine Piping and Valves
Marine systems often include complex fluid networks for fuel, cooling water, bilge, and waste. Using CFD, we simulate pressure drops, flow distribution, and transient behavior in pipes, valves, and pump systems, allowing designers to optimize performance and reduce energy losses.
We also evaluate surge events, such as valve closures and pump shutdowns, to protect against water hammering, noise, and mechanical damage in engine cooling, firefighting systems, or seawater intakes. For vessel fuel or oil systems, we model flow behavior under pitch/roll motion and varying fluid levels.
HVAC, Thermal, and Ventilation Simulations
Maintaining thermal balance and air quality on board is critical for both crew and machinery. We simulate airflow in engine rooms, control rooms, and accommodation areas, ensuring human comfort, proper ventilation, and heat rejection.
Our CFD services include:
- Cooling system analysis for generators and engine bays
- Cabin and corridor airflow modeling
- Exhaust flow management and emission ventilation
- Temperature control inside sealed compartments and cargo holds
By predicting airflow patterns, hot spots, and pressure zones, we help prevent thermal failures and ensure compliance with comfort and equipment cooling standards on modern vessels.
