Tonnage Surveys

• We are approved by the International Institute of Marine Surveying (IIMS) to perform tonnage surveys, a vital service for vessel registration, compliance, and legal documentation.

• A tonnage measurement is a mandatory requirement if you intend to register your vessel under Part 1 of the British Registry of Shipping, which is the formal register for UK-flagged vessels. This registry is essential for vessels that are involved in international trade or are required to demonstrate their UK nationality for legal or financial purposes.

• The main reasons for registering your vessel under Part 1 of the British Registry include:
  • Proof of Ownership: This provides a legal, internationally recognized record of ownership that can be essential for maritime disputes or claims.
  • Proof of the Vessel’s Nationality: Registering your vessel under Part 1 establishes its UK nationality, allowing it to fly the British flag and comply with UK maritime laws.
  • Marine Mortgage Security: If you plan to secure a marine mortgage, Part 1 registration provides a clear record of ownership that can be used to support financial agreements and help protect the interests of lenders.
  • Protection of Rights: Registration under Part 1 ensures that your vessel’s rights are legally protected, especially in terms of ownership and liability under British law.

In addition to UK-flagged vessels, we are also authorized to carry out tonnage surveys for vessels registered in Red Ensign States, which allows them to benefit from the same high standards of registry and flag protection. These include:

• Jersey (vessels under 24m LOA)
• Guernsey (vessels under 24m LOA)
• Isle of Man (vessels under 24m LOA)
• British Virgin Islands (BVI) (vessels under 24m LLL)
• Cayman Islands (vessels under 24m LLL)
• Gibraltar (vessels under 24m LOA)

Each of these jurisdictions follows regulations set forth by their maritime authorities, and we are accredited to ensure that vessels meet the specific criteria for registration in these regions.

A tonnage survey involves measuring and documenting the gross tonnage and net tonnage of the vessel, which is necessary for the formal registration process. The survey considers several aspects of the vessel, including:

• Overall Length & Beam: Accurate measurements are taken to ensure the vessel is correctly classified.
• Depth: These measurements impact the vessel’s overall tonnage calculation and cargo capacity.
• Internal and External Dimensions: The survey checks the vessel’s internal structure, including any compartments, holds, and decks that contribute to tonnage calculations.
• Volume Calculation: The surveyor uses the vessel’s shape and structure to determine the volume of the hull, which is crucial for establishing the vessel’s tonnage rating.

Once the survey is completed, the results are submitted to the relevant maritime authority for approval, and the necessary tonnage certificate is issued. This certificate serves as a key document for the vessel’s registration and may be required for insurance purposes, international shipping operations, or in securing financial loans.

As accredited tonnage surveyors, we bring years of expertise and thorough knowledge of both UK and Red Ensign States regulations. Our tonnage surveys are recognized by maritime authorities and provide an accurate, certified record of your vessel’s tonnage, ensuring that your registration process goes smoothly and complies with all necessary legal requirements.
