CONVERSION OF PANAMAX BULK CARRIER TO CONTAINER VESSEL
The main outline of the project involves conducting a comprehensive feasibility study of the conversion of Bulk carrier to a Container vessel.
Firstly, we determine the available container arrangement and prepare the stowage plan based on the requirements of the client. The uniform loads on the tank top, upper deck, and hatch covers are determined using as-built data, and Finite Element (FE) Analysis is conducted to assess the strength and behaviour of the vessel's main deck and hatches under the applied container load.
Intact and damage stability calculations are conducted to adjust the new metacentric height (GM).
Due to the criticality and complexity involved in container loading, considerable time was dedicated to finalize loading conditions without compromising on deadweight.
All the necessary plans and documentation required by the Classification society were prepared and submitted, and class approvals were obtained successfully.
ASSESSMENT TO CARRY WIND TURBINE BLADES ON GENERAL CARGO VESSEL
There has been an increase in demand for bulk carriers and general cargo ships to transport turbine blades for windmills. These blades are expensive and susceptible to damage, underscoring the importance of careful handling and attention during transport.
A stowage plan is prepared based on the arrangement and footprint load of windmill turbine blades. Structural, FEA and Intact and Damage stability analyses are conducted to ensure the ship remains within applicable limits. The stability conditions of the ship are verified, to allow for the carriage of turbine blades on the hatch covers and main deck of the vessel. The Lashing calculations & Cargo Securing Manual (CSM) is prepared in accordance with the Class and Statutory requirements. All the necessary plans and documentation required by the Classification society were prepared and submitted, and class approvals were obtained successfully.

- Marine Warranty Surveys
- Lashing & securing calculations.
STRUCTURAL ANALYSIS FOR LIFTING LUGS
Structural analysis was conducted to verify the lifting padeyes for the hull blocks. Determining the correct location of the lifting padeyes was crucial to ensure that the center of gravity was balanced during lifting.
Plans indicating the padeye locations on the hull blocks were prepared following the analysis and submitted to the classification society for approval. The hull blocks were then transported from Goa to Mumbai, where they were attached to the ship, one block at a time.
CONVERSION OF VEHICLE CARRIER TO LIVESTOCK CARRIER
The conversion of a vehicle carrier to a livestock carrier has been completed under Class. The Vehicle carrier, was converted to a Livestock carrier in Middle East.
The conversion process involves the preparation of statutory plans such as Stability Analysis, Tonnage Computation, Damage Control Plan, Damage Control Booklet and other relevant documents required by the Classification society. Our company’s representative conducted the Inclining experiment and submitted the final documentation to the Classification society for approval. The conversion of the Panama-flagged vessel was successfully completed.
CONVERSION OF GENERAL CARGO BARGE TO RSV OIL TANKER
Whether for new building or conversion projects, all initiatives begin with a technical discussion to understand the owner's requirements and specifications, which allows for accurate project definition.
For the conversion of a general cargo barge to an RSV oil tanker, a feasibility study was conducted and submitted to the owner. The conversion involved significant modifications, including the addition of longitudinal and transverse bulkheads, as well as a compartment for the pump room. Due to the increase in lightship weight, it was crucial to meet the freeboard and draft requirements to achieve the desired carrying capacity. Additionally, the conversion required the vessel to comply with the damage stability requirements set forth by MARPOL.
Design of India's First Advertisement Vessel
- AMS has designed India’s first 'Digital Advertisement Vessel' under the classification of the Indian Register of Shipping. The vessel is successfully operating at the Bandra-Worli Sea Link in Mumbai. A major challenge in this project was optimizing the design and steel weight of the vessel to accommodate draft limitations caused by varying water depths near the coastline. Additionally, we had to address stability requirements due to the high windage profile of the LED screens mounted onboard.
The collective efforts and teamwork of our naval architects and engineers overcame all hurdles and challenges, leading to the successful completion of this project.
SPS COMPLIANCE FOR SUPPLY VESSELS
In accordance with the requirements of the Indian Flag, Classification Rules, and IMO Resolution A.534(13) for SPS compliance, we prepared and submitted all necessary plans for Class approval. These included stability-related documents such as the Intact Stability Booklet, Damage Stability Booklet, Damage Control Plan, and Damage Control Booklet, as well as statutory plans like LSA (Life-Saving Appliances), LSS (Life-Saving Systems), FCP (Fire Control Plan), and Crew Accommodation plans. We also included machinery and navigation plans relevant to this compliance.
Our team of naval architects has successfully undertaken SPS compliance for various ships, ensuring that modifications were made without altering the main hull structure and with minimal interference with the existing arrangements onboard. All vessels are currently in operation and performing to the owner's satisfaction.
Conversion of Dredger into Oil Barge
- The feasibility of converting the vessel from a dredger to an oil barge was thoroughly assessed to meet the owner's requirements. All necessary plans and documentation required by the classification society were meticulously prepared and submitted for Class approval. This comprehensive documentation included structural modifications, stability analysis, and safety systems.
- The conversion process successfully transformed the vessel into an oil barge, with all regulatory and operational standards being met. The vessel is now fully compliant with the relevant regulations and is performing effectively in its new role.
STRUCTURAL ANALYSIS OF MAIN DECK, HATCH COVERS AND EXTENSION PLATFORM FOR LOADING OF WINDMILL BLADES ON BULK CARRIERS
- Our team has completed the structural analysis for the main deck and hatch covers, specifically for the loading of windmill blades, ensuring that stress levels remain within allowable limits. All necessary plans and documentation required by the classification societies, CLASS NK and ABS, were meticulously prepared and submitted for approval. The analysis was conducted within 24 hours and promptly forwarded to the client, enabling them to proceed with the blade loading operation without delay. This reflects our capability to provide round-the-clock service—24/7/365 —to meet our clients' needs effectively.
- Additionally, our team has designed the pedestals and performed structural analysis through both manual computations and software analysis for various arrangements, verifying that stress values are within allowable limits. We conducted weight estimation, prepared the drawings, and submitted them to CLASS NK and ABS for approval. Our naval architects have also carried out repetitive analyses for various vessels with different configurations to reduce structural weight and ensure optimal scantling. This approach leads to reduced material costs while maintaining structural integrity.
