Featured Naval Architect
Albert brings 20 years experience to the T&T Team.
T&T’s Naval architects regularly use HECSALV and GHS to perform structure and stability analysis following a vessel emergency.
The software is used to develop lightering plans and transfer sequences with accurate understanding of the condition of the vessel during these operations.
HECSALV is used to precisely direct and coordinate operations and keep the vessel well within acceptable limits during the operation. During Salvage operations on the Kiel Canal, T&T’s naval architects accurately predicted the amount of cargo discharge and dewatering that needed to occur. This contributed to a successful, safe and efficient operation.
T&T uses a host of sophisticated software programs, including AutoCAD, HECSALV, and General Hydro Statics (GHS), to provide the highest level of analytical and engineering capability available in the marine industry. Using the most powerful and flexible marine analytical programs, T&T can create and analyze ship models in both static and dynamic situations as well as pipelines, flexible risers and cables in offshore and inshore marine environments using sophisticated analytical salvage tools.
In recent years, T&T has moved into true 3D modeling, using software to create intelligent-adaptive models of components and assemblies. T&T can also perform static, dynamic, buckling, vibration stress, and heat transfer analysis on 2D and 3D structural and thermal models.
Argo Tank Barge
Lake Erie, USA
The 120' tank barge Argo, foundered and sank during a storm in Lake Erie in 1937. It was identified as a potential pollution threat by NOAA's Remediation of Underwater Legacy Environmental Threats (RULET) program so a site assessment was conducted. The Argo was found to be leaking an unknown extremely toxic and explosive substance containing benzene. It was thought that the cargo in 1937 was 4,762 barrels consisting of a 50/50 mix of benzol and crude oil. It was unknown how much material remained in the hold. A temporary patch was implemented until the EPA could conduct further analysis.
The T&T naval architects developed a hot tap plan for the emergency lightering of the Argo's cargo.
T&T safely removed the cargo in 2015 and submitted it for HAZMAT remediation.
Engineering for Any Scenario
T&T’s Naval Architecture analysis is critical to the success of a project. Many of the vessels encountered by the salvage crew are in extreme conditions in situations that they were not originally designed for. These casualties must be evaluated to determine their current structural strength and stability. All aspects of the casualty must be looked at. Working in close coordination with the salvage master the Naval Architect performs calculations to help guide and support a successful operations. With years of experience performing grounding calculations, developing lightering sequences, and solving complex engineering problems T&T’s Naval architects are ready to respond to any scenario.
With Planning Comes Success
T&T performs onsite modeling and analysis which helps guide real-time decisions and actions. Careful onsite analysis allows for more timely and safe operations. In several instances, T&T’s engineering modeling and calculations have enabled refloat operations without the need to lighter cargo. Smart out-of-the-box thinking, careful planning and years of experience lead to a safe, efficient, and successful operation.
