Dolfab Metal Fabricators and Metcalf Marine Exhaust recently collaborated on 164′ Delta marine M/V Helios 3 to conduct much needed repairs to the exhaust system.
It was discovered the Helios 3 was suffering from leaks in the exhaust system. The exhaust system on a super yacht like this is truly an enormous, impressive thing. In order to be able to access it for diagnosis and conduct necessary repairs, we had to disassemble the system in stages: one whole day and a half was allocated to dismantling it and three days to put it back together.
Upon dismantling the system, the team from Metcalf Marine Exhaust was able to go in and remove the insulation within the exhaust. With the insulation gone, the Metcalf team then conducted several pressure tests in order to locate the leaks. Once the leaks were located, the Dolfab crew was able to go in and make the necessary repairs to the super yacht’s mufflers. After the repairs were complete, Metcalf reapplied insulation and then Dolfab reassembled the entire shroud system, repolishing all of the exterior components as needed to maintain yacht-quality #8 mirror finish. This stage took three days to complete.
The result is a like-new, polished marine exhaust that works and is befitting of the Helios 3. Truly a fantastic collaboration between marine repair professionals.

In this video, Jim Doll explains the importance of a properly aligned transmission in superyacht applications. Troy’s transmission was misaligned after a series of events, and the shafts snapped. Listen to how it all happened:
S/Y Troy has been undergoing these yacht repairs for a few weeks now, as repairs conducted on superyachts are usually extensive and require vast amounts of knowledge and refined expertise.

DolFab Metal Fabricators recently completed extensive repairs on the hull of Ajao, a beautiful 80’ Baglietto yacht. Ajao suffered from major corrosion to its hull due to an issue with the external exhaust system. The yacht almost sank due to this corrosion and demanded an array of extensive refinements.
Dolfab was hired to perform repairs on the hull, fuel tanks, and bow. The process of repairing the Ajao was quite an undertaking. The scope of the project involved emptying the fuel tanks and removing corroded sections there, removing large sections of the yacht’s hull, replacing all the missing sections with customized new panels which were then welded into place, and finally pressure-testing the structure to ensure its seaworthiness.
The Dolfab crew found other issues on the yacht. The damaged hull created too much pressure and had caused the teak flooring on the bow to burst open. The team repaired and reinforced the structure of the bow, going through the forward bulkheads to ensure the yacht is seaworthy after all repairs are finished.
Ajao passed the pressure testing procedures and was scheduled for fiberglass repair and paint before it was relaunched earlier this month. Ajao has now been restored to its former glory!
