Pre-purchase vessel condition survey

Before acquiring a vessel, it is important to compare the available information with its condition in the field. TWS Maritime Service performs pre-purchase surveys and provides support and partnership to specialist companies in vessel pricing, valuation and approval. The objective is to provide organised evidence so that the client and its specialists can identify outstanding matters and make decisions on a clearer technical basis.

When to engage

The service is intended for buyers, shipowners and charterers who need to understand the condition of a vessel under assessment. It also supports specialist companies requiring on-site information for their analyses. Before the visit, we define the priority systems, available documents and access conditions, according to the purpose and time allocated for the survey.

Survey scope

Planning may cover the vessel from bow to stern, including the rudder and propeller where accessible. Subject to the appointment and confirmed means, the assessment may include:

• Hull, structures, deck, accessible compartments and apparent condition of coatings.
• Cranes, deck equipment and components relevant to the intended operation.
• Engines, auxiliary equipment, propulsion and steering systems, to the agreed level of examination.
• Maintenance records, presented certificates and information on repairs or interventions.
• Comparison between field findings and documentation, identifying matters for further investigation.

What the client receives

The report compiles technical observations, photographs and identification of the areas and systems examined. It distinguishes on-site findings from documentary information or information supplied by third parties and states what could not be verified. These elements assist with questions to the seller, additional due diligence and analyses by specialists responsible for pricing or approval.

Limitations and supplementary verifications

Submerged parts, internal components and performance under load may require dry-docking, underwater inspection, dismantling, testing or sea trials. These activities depend on authorisation, contracting and appropriate resources. The survey does not replace class, statutory certification or financial valuation and does not guarantee the absence of hidden defects; the purchase decision remains with the client.

Request this service

Send the vessel name and IMO, type and location, purpose, assessment deadline, available documentation and anticipated access conditions. State the involvement of other specialists so that we can align the survey with the team's needs.

Frequently asked questions

Can the rudder, propeller and machinery be included in the survey?

Yes, subject to the scope and conditions of access and examination. Submerged or internal components may require supplementary activities, which must be agreed in advance.
