BSI provides a vast range of mechanical engineering services including fault-finding, fabrication, modification and ship repair services. We offer world-class craftsmanship through artisans with years of experience ranging from semi-skilled to qualified red seal artisans – hydraulic experts, electricians, boilermakers, welders, mechanical fitters and millwrights.

Our highly skilled project engineers work closely with the ship superintendent to ensure that every completed project adheres to both our exceptionally high standards as well as client specifications.


We offer a wide range of repairs to truck mounted, mobile, knuckle boom and king post cranes, as well as aerial platform lifts. Additionally, we offer refurbishment and replacement of deck crane sheaves, wire rope, crane booms and tilt cylinders as well as fabrication & installation of bushes and pins.

Vapour Abrasive Blasting

Vapor abrasive or Wet abrasive blasting is a more efficient way of  removing  coatings, contaminants, corrosion and residues from hard surfaces. It is similar to dry sand blasting but introduces moisture into the blast media prior to impacting the surface.

The advantage of vapor abrasive blasting over sand blasting is that it reduces dust, allowing operators to work in a wide range of environments with minimal setup and cleanup costs. The result is a cleaner and more consistent finish that is ready to coat, with no embedded particles or clinging dust.
