Welcome to Nunes Assessoria Marítima

Draft survey is a method used to determine the weight of cargo loaded or discharged from a ship. This is done by measuring the ship's draft (the vertical distance between the waterline and the bottom of the hull) before and after the cargo operation. Here's a detailed outline of the draft survey process:

Preparatory Steps

Obtain Vessel Particulars:

Hydrostatic data:Information about the vessel's draft and corresponding displacement, including corrections for trim, water density,and hull deflection.

Tank data: Capacities and contents of all tanks (ballast, fuel, freshwater, etc.).

Trim and list tables: Data for correcting draft readings based on the ship's trim (fore-aft inclination) and list (side-to-side inclination).

Environmental Conditions:

Water density:Measure the density of the water in which the vessel is floating, as it affects buoyancy.

Weather conditions: Note the wind and sea conditions, as they can affect the vessel's draft.

Draft Measurement

Read Draft Marks:

Forward, midship, and aft: Measure the draft at three points on each side of the vessel.

Corrections for trim and list: Apply corrections to account for any inclination of the vessel.

Record Readings:

Draft readings:Document the draft readings carefully, noting the positions and any observable factors affecting the readings (e.g., waves, swell).

Calculation of Displacement:

Hydrostatic Tables:

Displacement from tables: Using the corrected draft readings, refer to the hydrostatic tables to find the vessel's displacement.

Trim and List Corrections:

Adjust displacement: Apply necessary corrections for trim and list to get the accurate displacement.

Tank Sounding:

Measure Tank Contents:

Sound tanks: Measure the contents of all tanks (ballast, fuel, freshwater, etc.) to determine their weight.

Density Corrections:

Correct for density:Adjust the measured tank contents based on the density of the liquids.

Cargo Weight Calculation

Calculate Lightship Weight:

Lightship displacement: The weight of the vessel when it is empty (including ballast, fuel, stores, and crew).

Determine Cargo Weight:

Cargo weight before loading:Measure the displacement before loading, including any corrections for tank contents.

Cargo weight after loading:Measure the displacement after loading, including any corrections for tank contents.

Net cargo weight: Subtract the before-loading displacement from the after-loading displacement to determine the weight of the cargo loaded or discharged.

Report and Documentation

Draft Survey Report:

Document findings:Prepare a detailed report including all measurements, corrections, calculations, and environmental conditions.

Verification: Ensure the accuracy of the data by cross-checking with ship's officers and other relevant parties.

Certification:

Official records:Provide the draft survey report to relevant authorities, shipping companies, and cargo owners as required.

Importance of Draft Surveys

Accuracy: Provides precise measurement of cargo weight, critical for shipping, trading, and regulatory compliance.

Efficiency: Helps in optimizing loading and unloading operations.

Safety: Ensures the vessel's stability and seaworthiness by maintaining proper loading practices.

 A bunker survey is an inspection conducted to verify the quantity and quality of fuel oil (bunkers) on board a vessel. This survey is critical for various stakeholders, including shipowners, charterers, and bunker suppliers, to ensure accurate recording of fuel inventory and compliance with contractual agreements. Here's an overview of the bunker survey process:

Purpose of a Bunker Survey

Verification: Confirm the amount of fuel on board at a specific time.

Compliance: Ensure adherence to regulations and standards.

Dispute Resolution: Provide evidence in case of disagreements between parties involved.

Types of Bunker Surveys

On-Hire/Off-Hire Surveys: Conducted when a vessel is being delivered to or redelivered from a charterer.

Bunker Delivery Surveys: Conducted during the delivery of fuel to the vessel.

Intermediate Surveys: Performed periodically to check the bunker quantity and condition.

Steps in a Bunker Survey

Preparation:

Review the vessel’s fuel logs and delivery receipts.

Confirm survey details with the vessel's crew and relevant parties.

Tank Sounding:

Measure the fuel levels in each bunker tank using sounding tapes or electronic gauging devices.

Record temperatures of the fuel to account for density variations.

Sampling:

Collect fuel samples from different tanks and the delivery line.

Follow standard procedures to ensure representative sampling.

Calculation:

A vessel's condition survey is a comprehensive inspection and assessment of the physical and operational condition of a ship or boat. This type of survey is typically conducted by marine surveyors, who are professionals with expertise in evaluating the condition of maritime assets. The purpose of a vessel's condition survey is to determine the vessel's overall health, identify any deficiencies or potential issues, and provide an objective assessment for various stakeholders, such as owners, insurers, or potential buyers.

Here are some key aspects typically covered in a vessel's condition survey:

Hull and Structure:

Inspection of the hull for signs of damage, corrosion, or deterioration.

Assessment of the structural integrity and overall condition of the vessel's framework.

Machinery and Equipment:

Examination of the propulsion system, including engines, gears, and propellers.

Inspection of auxiliary systems such as generators, pumps, and other machinery.

Electrical Systems:

Evaluation of the vessel's electrical systems, wiring, and components.

Testing of navigation lights, communication equipment, and other electrical devices.

Safety Equipment:

Verification of the presence and condition of safety equipment, including life jackets, life rafts, fire extinguishers, and signaling devices.

Navigational and Communication Systems:

Testing and inspection of navigation instruments, radar, GPS, and communication devices.

Interior and Accommodations:
