In detail
How this segment is brokered
What you can broker through this desk
Diving support vessels with saturation systems installed; handled in coordination with the diving desk.
Offshore support vessels (OSVs); PSV, AHTS, ERRV; and multipurpose support vessels (MPSVs) for IRM, construction and project work.
Survey vessels and dedicated geophysical platforms; including ROV-equipped survey vessels.
Multicats, workboats and inshore craft for port operations, wind O&M and inshore construction.

How vessel brokerage runs at Dockstr
Vessel transactions typically run 3 to 9 months from mandate to close. Inspection, class transfer, flag change, contract negotiation and operational transition all sit inside that window.
Our role is the deal: matching buyer to seller, negotiating terms and coordinating between parties through to delivery. For inspection, class transfer and legal, we connect you with the right specialists.
Survey vessel; project tonnage for offshore and coastal operations.
Where we are strongest
Our equipment background gives us a real edge on DSV, survey vessels, cargo barges and offshore construction units. We know the kit on board, the contractors who run it, and the buyers who need it.
For other tonnage, OSVs, AHTS, crew vessels and workboats, we either run it ourselves or partner with specialist shipbrokers depending on the mandate.

FAQ
Common questions
Do you handle charter as well as sale?
Sale is our core focus. We can assist with charter enquiries on a case by case basis, and this is a service we are expanding.
Can I list anonymously?
Yes. We handle off-market and anonymous listings. Vessel details are circulated to our buyer network while the seller’s identity stays confidential until both parties are ready to engage.
Are auction sales handled?
We may participate in distressed and judicial sales on mandate, but our standard model is a structured private brokerage.
Which vessel types are tightest right now?
DSV tonnage, multicats and wind O&M workboats sit in structural short supply. OSV availability tracks the drilling and construction cycle and can swing either way inside a quarter.
Do you broker cold-stack and lay-up tonnage?
Regularly. Reactivation cost is scoped transparently in the data pack so buyers can model total cost-to-on-hire, not just headline purchase price.
What is the typical timeline on a vessel sale?
3 to 9 months mandate-to-close is typical, depending on inspection logistics, class transfer, flag change and crew transition.
