Naval Architectural Support and Marine Vessel Design
We specialize in Engineering and Design Services related to the Marine industry with wide range of services towards Ship and Boat Design.
We involve ourselves in the design process comprehensively by catering to owner’s requirement at all phases of a ship design and ship building process.
Our strength lies in evolving basic designs and thoroughly engineer the design to optimize the design for better and efficient use of available space and
the performance of the vessel.

Mooring and Raiser Analysis
The offshore environment is very complicated in nature which poses several kinds of risks that amalgamate and develop further complicated risks involved in the execution of any work, which makes it extremely important to accurately and correctly analyze and also design the support systems that are going to significantly affect the safety and operations.
Aivot’s expertise lies in the pool of its professions. The congomolate of technical knowledge industry experience and understanding of project’s application and requirements allows Aivot undertake variety of complicated projects and deliver it bettering the expectations of the client,
• Mooring Analysis of offshore work-cum-accommodation barges
• Riser and Mooring Analysis
• Pipe-laying Analysis
• General Line dynamics and motion prediction
Mooring Analysis is one of the most essential tool in simulating the complicated nature at stations in ensure safety and reducing risk during offshore operations. Mooring analysis mostly required in the cases like:
• Complex platform and sub-sea infrastructure
• Vessel positioning in close proximity to assets
• Longer mooring durations
• Operational requirement: gangway connections, helicopter operations
• Operational requirement: Vessel response under accidental damage of a line
• Operational requirement: Support vessel's movement in close proximity to barge
• Operational requirement: Unconventional requirements: Connection to Jacket leg, DP buoys etc.
Riser-mooring coupled analysis
• Time domain dynamic coupled analysis
• Non-linear large displacement analysis
• Modal analysis
• Fully coupled tension, bending and torsion analysis
Jetty Mooring Analysis
• Heavy weather mooring analysis
• Line load calculation
• Jetty / Fender load calculation
• Mooring Plan
