Engineering Design and Technical Documentation
We develop complete packages of design and engineering documentation, with a particular focus on the key aspects of vessel operation.
Safe Cargo Transportation
Detailed calculations and recommendations to ensure reliable and safe transportation.
Stability and Seaworthiness
Advanced engineering methods to ensure vessel stability and safety under all operating conditions.
Vessel Structural Strength
Comprehensive analysis of the structural integrity of the hull and its components.
Main Types of Design Documentation
Engineering solutions for vessel operation and equipment arrangement
- Freeboard Calculation: determination of the required freeboard to ensure sufficient reserve buoyancy in accordance with applicable international regulations.
- Deadweight and Gross/Net Tonnage Calculation: determination of the vessel’s carrying capacity and enclosed volume in accordance with the International Convention on Tonnage Measurement of Ships, 1969 (TONNAGE 69).
- Equipment Number Calculation: determination and optimisation of the required anchoring, mooring, and towing equipment according to the vessel’s dimensions and characteristics.
- Stability Information Booklet: preparation of documentation containing vessel stability calculations for various loading and operating conditions.
- Grain Stability Booklet: specialised stability calculations for the safe transportation of grain cargoes, taking into account cargo shifting.
- Damage Stability Booklet: analysis of vessel behaviour, survivability, and stability following damage to the hull.
- Loading Manual: instructions for the correct distribution of cargo and optimum vessel loading to ensure safe operation.
- Cargo Securing Manual: requirements and recommendations for the reliable securing of cargo during transportation.
Vessel Reclassification Services
We carry out vessel reclassification procedures for vessels transferring to the supervision of the Russian Maritime Register of Shipping from IACS classification societies, as well as for vessels without an existing class.
Compliance Assessment
A comprehensive assessment of vessel compliance with RMRS/RCS rules and international conventions, including recommendations and a detailed list of identified non-conformities.
Comprehensive Calculations
Recalculation of freeboard, tonnage, intact and damage stability, and the global and local strength of the vessel’s hull.
Documentation Development
Preparation of the required Stability Information Booklet, Loading Manual, and other essential vessel documentation.
Condition Assessment
Determination of the permissible residual scantlings of hull structural members and assessment of the vessel’s technical condition in accordance with RMRS or other classification society requirements.
Drawing Preparation
Development of as-built general arrangement drawings, capacity plans, and equipment arrangement drawings.
Statutory Vessel Documentation
We develop all required statutory documentation and provide support throughout the approval process.
- Fire Control and Safety Plan.
- Plans and Procedures for Recovery of Persons from the Water.
- Garbage Management Plan.
- Shipboard Oil Pollution Emergency Plan.
- Ballast Water Management Plan.
- Ship Energy Efficiency Management Plan.
- Calculation of the Rate of Discharge of Untreated Sewage.
Additional Services
- Inclining Tests and Lightweight Surveys: performance of tests and measurements to determine the vessel’s actual lightweight and stability parameters.
- Projects for increasing cargo capacity and for the modernisation and conversion of vessels and floating structures: development of technical solutions to improve operational efficiency and adapt vessels to new tasks.
- Preparation and approval of vessel relocation and delivery voyage projects: development of documentation and technical measures required for the safe relocation of a vessel between operating areas.
All documentation developed by our team fully complies with the requirements of international conventions, national regulations, flag administrations, and classification societies and is subsequently submitted for mandatory review and approval. Widson is your reliable partner in modern shipbuilding and maritime engineering.
