Naval Architecture
Seakeeping, maneuvering, towing, moorings, piles, hydrodynamics
DSA works extensively with naval architecture firms to predict the motion of vessels and platforms. These seakeeping studies help to improve performance and validate design requirements. The validated panel method ShipMo3D software that DSA maintains and develops is used to assess the effect of bilge keels, rudders, thrusters, and other appendages on ship motion.
The use of both ProteusDS and ShipMo3D enables us to complete mooring analysis for marine structures such as barges and offshore platforms. In addition to specifying line sizes and types in accordance to standards, we typically determine loads on the fairleads to be used for winch selection and structural design.
DSA has been involved in numerous unique projects. For example, DSA has experience modelling push-boat or tug boat manoeuvring; these complicated simulations include contact forces, line dynamics, and multi-body hydrodynamics. In addition, we have modelled floating pipelines and debris booms and their mooring systems for oil sands tailings ponds. This experience combined with our customizable software makes us a very strong partner on any new technology development.
- Current
Determine the impact of large-scale eddies and turbulence on marine operations and mooring systems using time and spatially varying current data.
- Hydrodynamics
Examine the coupled motion and loads of moored floating and submerged platforms.
- Marine Operations
Assess marine operations such as launch and recovery and cable lay operations.
- Towed Systems
Use RAOs to compute vessel motions and determine their effect on the tensions in towed arrays.
- Seakeeping
Develop RAOs and perform coupled mooring simulations using ProteusDS and ShipMo3D.
- Winches
Verify performance of heave compensation winches that are commonly used on vessels.
