MV MAKOURIA Refined for Peak Performance

Overview

The drydocking of MV MAKOURIA at our facility spanned from August 25, 2022, to September 19, 2022. During this period, an extensive range of maintenance and repair activities were carried out to ensure the vessel’s optimal performance and longevity. Below is a detailed overview of the executed works

Painting

• The hull was painted with four coats of protection
• Two complete coats of coal tar epoxy from the keel to the top of the bulwarks.
• Two coats of antifouling paint from the keel to the waterline.
• Two additional coats of black marine paint above the waterline.
• The vessel’s name, port of registry, and draught marks were repainted at designated areas to ensure visibility and compliance

Structural Repairs

Waterline Cutting

The waterline was carefully cut to align with new specifications

Anodes Installation

The waterline was carefully cut to align with new specifications.
Anodes Installation: Ten kilograms of zinc anodes were supplied and installed to prevent galvanic corrosion

Plating Repairs

Deteriorated hull plates were cropped out and replaced using 10 mm plating, addressing any structural weaknesses
