This extension was designed by Austal Ships and required six months to complete. We removed the rear 2 MTR section off Tango. Our certified aluminium boat builders began fabricating the extension in sections, using aluminium router cut parts. This project involved a lot of different tradesmen working together. All our aluminium works were carried out to Lloyds standard including x-rays to all butt welds on hull plating ( 100% pass rate ) We fabricated 4m x 2.5m water tight hydraulic hinged door. Hinges fabricated from 10mm & 12mm 316 stainless steel , sanded & polished to mirror finish.
