Digital draught survey technology
WHAT IS
Our breakthrough DRFT MRKS technology provides an accurate measurement of vessel draft.
It is an industry-leading AI technology which we developed to improve the traditional draft reading process.
DRFT MRKS allows anyone to read draft marks with same skill and accuracy as an experienced mariner.
HOW DOES IT WORK?
1 RECORD
Use your smartphone to capture 30-60 second video of the vessel’s draft marks.
2 UPLOAD
As soon as it is uploaded to our secure database, DRFT MRKS will process the video in less than three minutes.
3 RESULT
Receive an accurate draft survey reading, along with confidence limits, back in your smartphone app.
“Disruptive product-led innovations like DRFT MRKS will transform the mariner experience contributing to safer, more efficient operations at sea.”
KEY FEATURES
Highly portable mobile phone app removes subjectivity
Generate accurate operational material
Can be used on all types of draft marks
Reduces burden on surveyor and improves crew safety
Accurate air gap calculations
Results securely stored in case of future disputes
THE ROLE OF DRAFT SURVEY
The draught of a vessel is a measure of the distance between the surface of the water where it meets the hull of the vessel – the waterline – and the keel or baseline of the vessel.
Accurate draught readings are essential for ensuring a vessel’s stability – determining how much cargo it is carrying and what depths it can safely navigate.
For a ship, draught mark readings are read during cargo surveys, when the outcome is directly connected to the contractual value of the cargo. For a semisubmersible, draught mark readings are a critical indicator of how much equipment can be safely loaded
THE NEED FOR INNOVATION
Despite their historical importance, visual draft surveys have been marred by inaccuracies stemming from environmental factors and human error. These discrepancies can lead to incorrect displacement measurements, sparking disputes over cargo quantities and imposing operational limitations on vessels.
According to a report from Swedish Club, the majority of cargo shortage claims in bulk carriers transporting grains are due to differences between shore and the vessel’s figures, which are always calculated using visual draft readings.
DRFT MRKS provides a single verifiable source of truth for calculating vessel displacement using draft marks, accurately determining loaded cargo/equipment, and determining whether any weight discrepancy will trigger an inclining test
