FAQ
Common questions
Can equipment be brokered while still installed on the vessel?
Yes. We regularly broker assets in-situ, with removal handled as part of the sale.
Do you broker mooring and anchor handling equipment?
Yes. Mooring lines, chain, anchors and anchor handling tooling are handled through this desk and the offshore construction desk depending on scope.
What about cranes without current certification?
We list them transparently as ‘cert lapsed’ and price accordingly. Recertification path is included in the data pack.
Do you sell marine engines or propulsion?
Yes. Marine diesel engines, gensets and propulsion units are brokered through this desk, typically coming off repowers, conversions and decommissioning.
Are A-frames and LARS categorised here or under ROV?
LARS and A-frames live here under Marine Equipment because they are deployment hardware. Buyers sourcing a complete ROV and LARS spread are typically routed via the ROV desk; we coordinate across desks.
Do you broker shipyard surplus in bulk?
Occasionally. Yard-clearance lots covering mixed deck equipment come up from time to time; where they do, we structure them as packages or break them into line items based on the buyer pool.
