CONSTANTA SHIPYARD – READY FOR BWTS & SCRUBBERs INSTALLATION
Serving a wide range of ship-owners and ship management companies worldwide and anticipating the forthcoming challenging years in what concerns retrofitting works for compliance with new regulations , i.e BWTS & scrubbers installation, Constanta Shipyard focused within last couple of years in preparing and gaining the needed experience for such works.
Started two years ago with pre-arrangement for BWTS installation on several MR tankers (construction of deck roof, installing pipes, valves ,etc) , the retrofitting experience continued with full BWTS package installation on SUEZMAX and AFRAMAX tanker ships.
Considering the specificity required by the design of particular systems ( i.e. chlorination based ), the Shipyard trained its own pipe fitters team for installation of GRE pipes,  in parallel with assigning dedicated and experienced repair project managers to follow these projects .
In 2018 , an AFRAMAX of one of our traditional Italian customers performed in Constanta Shipyard a complete BWTS installation  ( an UV principle based equipment), including the commissioning.
The main scope of works (apart to relevant standard volume of DD & repair jobs), was mainly consisting of :

Retrofit installation of Water Ballast Treatment System
