Our Survey Services

Pre-Purchase Survey
Conducted before the purchase of a vessel to provide the buyer with an assessment of the vessel's condition, seaworthiness, and value. Includes a thorough inspection of the hull, structure, machinery, equipment, and systems.

Condition Survey
Evaluates the overall condition of a vessel, identifying any defects, damages, or deficiencies that may affect its safety, performance, or value. Often conducted for insurance purposes, financing, or routine maintenance planning.

On/Off Hire Survey
Specialized survey conducted to assess the condition of a vessel or marine equipment at the beginning (on-hire) and end (off-hire) of a charter or lease agreement — documenting condition and determining any changes or damages during the charter period.

Towage Survey
Specialized inspection to assess the condition of a vessel or structure intended to be towed, as well as towing arrangements and equipment, ensuring safe and efficient towing operations and compliance with regulatory requirements.

Damage Survey
In the event of an accident, collision, or other incident resulting in damage to a vessel, a damage survey assesses the extent of the damage, determines the cause, and recommends necessary repairs or corrective actions.

Bunker Survey
Specialized inspection conducted to verify the quantity and quality of fuel (bunker) onboard a vessel — ensuring compliance with contractual agreements, preventing discrepancies, and mitigating risks associated with fuel procurement and consumption.

Draft Survey
Critical assessment to determine the displacement of a vessel by measuring the change in draft before and after cargo loading or unloading — essential for accurately calculating cargo quantities, verifying weight compliance, and ensuring safe navigation.

Vessel Feasibility Survey
Comprehensive assessment to evaluate the suitability and viability of a vessel for a specific purpose or operation, identifying potential challenges, risks, or limitations for transportation, offshore operations, or specialized projects.
Frequently Asked Questions
Common questions about marine surveys
What is a pre-purchase ship survey?
A pre-purchase survey is a comprehensive inspection of a vessel's hull, machinery, equipment, and documentation conducted before a sale. It identifies defects, estimates repair costs, and helps buyers assess the vessel's condition and fair market value.
What is an on/off hire condition survey?
An on-hire survey documents a vessel's condition at the commencement of a charter, and an off-hire survey at the end, to determine what damage or deterioration occurred during the charter period for commercial settlement between owners and charterers.
How is a draft survey conducted for bulk carriers?
A draft survey determines bulk cargo quantity by measuring the vessel's draft forward, aft, and midship before and after loading or discharging, then calculating the change in displacement. It is widely used for coal, grain, and ore cargoes.
What is a bunker survey and when is it required?
A bunker survey measures and verifies the quantity (and often quality) of fuel oil on board or transferred. It is required during vessel deliveries, redeliveries, bunker transfers, and whenever disputes arise between owners, charterers, or bunker suppliers.
