My name is Davide Ramponi, I am 20 years old and I am currently doing an apprenticeship as a shipping agent in Hamburg. On my blog, I take you with me on my journey into the exciting world of shipping. I share my knowledge, my experiences and my progress on the way to becoming an expert in the field of 'Sale and Purchase' – the trade in ships.

One of the most important topics in the ship buying and selling process is due diligence. Whether you are a buyer or a seller, this step is crucial to minimise risks and understand the actual value of a ship. But what exactly does due diligence mean and how does it work? In this article, I will show you why it is so important, which steps you need to consider andhow to solve common problems.
Definition and meaning
In the context of a sale and purchase, due diligence describes the process of thoroughly checking a ship before it is bought or sold.
Why is due diligence important?
This process helps to identify hidden risks and percentage problems. The aim is to ensure that the ship meets expectations technically, legally, and economically. A well-executed due diligence process protects buyers from expensive surprises and gives sellers the opportunity to rectify any weaknesses at an early stage.
Who is involved?
In addition to buyers and sellers, brokers, technical surveyors, lawyers, and classification societies play a central role in the due diligence process.
Steps of the due diligence
The due diligence process is divided into several steps that focus on different aspects of the ship. Each of these steps is important to get a complete picture of the ship.
1. Technical inspection
The technical inspection is the core of the due diligence process. This is where the physical condition of the ship is thoroughly examined.
What is looked for?
The main engines, generators, hull, deck equipment, and electrical systems are the focus of attention. An inspector will check for signs of corrosion or cracks, which could indicate that major repairs are potentially imminent.
Why is it important?
Technical defects can not only be expensive, but can also affect the safety and operation of the ship. A thorough and professional inspection helps to identify hidden problems at an early stage, so that you can react in time.
2. Checking legal documents
Legal documents play a central role in ensuring that the ship can be bought or sold without legal obstacles.
Important documents:
Registration certificates
Classification reports
Maintenance records
What is checked?
Are there any outstanding mortgages or liens on the vessel? Has all maintenance and inspection been carried out properly?
3. Vessel history
A vessel's history can say a lot about its condition and future reliability.
Important information:
Previous owners and uses
Accidents or major repairs
Changes in registration
Why is it important?
A vessel with a clear and well-documented history is more trustworthy and often achieves a better price, and it helps to ensure a smooth sale/purchase process.
Tools and checklists
Due diligence requires organization and precision. Tools and checklists can help to make the process efficient.
1. Digital tools
Databases: Platforms such as Clarkson Research or Baltic Exchange provide access to important market and ship data.
Inspection tools: Digital tools such as drones or underwater robots can help to inspect parts of the ship that are difficult to access.
2. Checklists
A good checklist ensures that nothing is overlooked. Here are some items that should not be missing from any checklist:
Technical inspection: condition of main engines, hull, and equipment.
Legal documents: registration, mortgage status, and certificates.
History: accidents, repairs, and previous owners.
Common problems and solutions
Despite careful planning, problems can arise during due diligence. Here are some of the most common challenges and how to solve them:
1. Technical defects
Problem: The surveyor discovers serious technical defects.
Solution: Negotiate repairs or a price reduction with the seller. Alternatively, you can reject the ship if the costs outweigh the benefits.
2. Unclear documentation
Problem: Missing or incomplete documents.
Solution: Request complete documentation from the seller and work closely with a lawyer to minimize legal risks.
3. Time pressure
Problem: The purchase process must be completed quickly, which makes due diligence more difficult.
Solution: Prioritise the most important checks and use experienced professionals who can speed up the process.
Conclusion
Due diligence is an indispensable step in the sale and purchase process. It gives buyers the security of making an informed decision and offers sellers the opportunity to present the ship in the best condition. With the right tools, a clear checklist and a professional team at your side, you can minimise risks and make the process efficient.
