Merchant Shipping

This division is further split into the following divisions:

• SHIP REPAIRS: Ship Repairs would include the following:

• Kettle Patches,
• Crack Arrests,
• Installation of cofferdams
• Blanking of seawater inlets or overboard discharges for in board repairs
• Sealing stern tube glands
• Replacement of wasted anodes (welded on or bolted on)
• Repairing damage by underwater welding and patching or steel plate insert by means of cofferdam and crack arresting
• Taking rudder pintle and tail shaft measurements
• Non destructive testing for plate thickness
• Cropping of damaged propeller blades

• IN WATER SURVEYS: These are further split between:

• Photographic Surveys
• CCTV Surveys.

Our experienced teams have the capability to handle every aspect of the underwater inspection process, producing detailed reports for a wide variety of purposes including:

• Damage assessment
• Preparation for sale or purchase
• Assessment of anti fouling paint systems
• General inspections of hulls, plating, welding, water intakes, propeller and rudder
• Assessment of general hull condition and/or damage for classification society approval to extend dry dockings
• Preparation for dry dockings.

Class surveys can vary in detail and length dependent upon the requirements of the client. The degree of reporting depends on whether the survey is undertaken for specific months or for two or three years of a dry docking extension period or in lieu of dry docking.

• Inspection capabilities

• Visual with photo documentation
• Closed circuit TV and video
• Crack detection and definition
  

• HULL CLEANING:A known fact that every dollar spent on a Hull Clean and Propeller Polish saves the company $8 in fuel. Hull cleaning includes the cleaning of the following:

• Flat Bottom,
• Vertical Sides,
• Sea Chests Grids,
• Rudder.

Our expertise in this field runs to over 1 000 vessels of all different lengths and drafts.

We are specialised in a mixed gas system that allows our divers to continue with a hull clean where the vessel is drafting over 12m. For these services the fees are slightly higher but it has been known that this system is effective and efficient.

• PROPELLER POLISHING: Thousands of dollars are lost annually due to the inefficiency of the propeller. A Propeller Clean is completed first where all growth is sanded off and then the disc pads are changed for polishing pads to complete an A Grade Propeller Polish finish as measured by the Rupert Gauge Roughness Comparator.

This can be caused by many things namely:

• Marine Growth
• Mechanical Damage

What effect does this have on the vessel?
• Increased drag resulting in increased torque
• Decreased thrust
• Increased load on propulsion plant at a given speed
• Increased fuel consumption
• A smooth and properly polished propeller costs less to maintain, reduces fuel consumption by up to 10 percent and does not foul easily.
