MV Tramp Workboat Revamp
The MV Tramp is owned by Neumann Contractors and is used as a workboat for Neumann Dredging. It is used as a multi-purpose work version that tows, refuels moves anchors and a transfer vessel for the dredging fleet.
The harsh saltwater working conditions eventually takes its toll and it is time for a well need tidy up.
Scope of Works
Abrasive Blasting
First up it was blasted in our 15m long x 7m wide x 7m tall Abrasive Blasting Booth with Crushed Glass to remove all the paint and rust.
Primer
It was then primed with Wattyl PR250 Epoxy Primer. The Epinamel PR250 is a great universal two pack expoxy primer for steel and non-ferrous metals and has excellent water and corrosion resistance.
Top Coat
We used Wattyl’ Epinamel DTM985 for the top coats, which is a resistant to alkali, mineral oil solvents and dilute acids. It is also very suitable for full immersion in slat water.
Jotun SeaGuardian Anti foul was also used. Antifouling SeaGuardian is a tin free selfpolishing antifouling. IMO Anti-fouling System Convention compliant (AFS/CONF/26).
