Real work from our workshop and from vessels — short case studies from boiler, heat exchanger, IGG, BWTS and hull projects.
BOILER12 t/h composite boiler • Tuzla workshop
The full tube bundle was removed, wall thickness surveyed and new tubes fitted with TIG welding. The boiler passed a hydrostatic test at 1.5x working pressure and was handed over in the presence of the class surveyor.
PLATELube oil cooler • Workshop service
Plates were stripped and ultrasonically cleaned, deformed plates replaced and the pack reassembled with original gaskets. The tightening dimension was set to manufacturer tolerances.
SCAVENGEMain engine • Workshop fabrication
The finned tube bundle was re-manufactured in the workshop and pressure-tested on both air and water sides. Fitted with a new gasket set and shipped to the vessel the same day.
IGGInert gas generator • Tanker
Combustion chamber refractory was removed, the shell renewed and castable lining applied. Burner and gas path were cleaned, the O2 analyser calibrated and commissioning completed.
BWTSPump room • Installation & commissioning
The system module was placed in the pump room and piping and flange connections completed. Commissioning tests were reported together with flow and TRO measurements.
SCRUBBERExhaust gas scrubber • Shipyard
The scrubber tower shell, circulation line and nozzle manifold were fabricated in the workshop and erected onboard. pH and flow sensors were calibrated and washwater analysed.
REFRACTORYWaste incinerator • Confined space
Castable lining was applied inside the incinerator chamber; anchors were renewed and the curing programme followed the manufacturer's instructions. Lining thickness and crack inspection were reported.
ENGINEAuxiliary generator • Onboard
The generator engine was fully stripped and overhauled; cylinder heads, injectors and bearings were inspected. It was returned to service after load testing and oil analysis.
HULL340 m² plating • Dry dock
340 m² of plating was renewed in dry dock, with cutting and welding carried out to class-approved procedures. Handed over after ultrasonic inspection and coating.
VALVEBoiler safety valves • Workshop testing
Safety valves were removed and bench-tested for set pressure and tightness. Certified test reports were issued after calibration.
BOX COOLERSea water circuit • Workshop
The box cooler tube bundle was renewed, shell corrosion cleaned and gaskets replaced. Sea water side pressure testing was completed after assembly.
PRESSURE VESSELHot water tank • Class certified
A custom-sized pressure vessel was fabricated; class certification was issued after WPS/PQR approved welding and hydrostatic testing. Material certificates were filed.
