Fuel constitutes the single largest operating cost of a vessel today, and efficient hull cleaning and propeller polishing can save substantial amounts of money, having been shown to improve efficiency by up to 15%. Our divers are experienced and diligent, ensuring your vessel is cleaned to a high standard ready for her onward passage, with varying packages depending on the time you have available.  Propeller surface roughness directly effects propeller efficiency, and a higher propeller efficiency equals lower fuel consumption. If done right and done regularly it can result in 5% or even more fuel savings.



Fuel constitutes the single largest operating cost of a vessel today. This makes Hull Efficiency a key to operational compliance and vessel economic success. SG-SALVAGE has the right equipment designed for managing even the most sensitive coatings.

SG SALVAGE are Recognised External Specialists for In-Water Survey (IWS) for the American Bureau of Shipping (ABS) and Registro Italiano Navale (RINA), allowing us to conduct IWS and UWILD (Underwater Inspection in Lieu of Dry-Docking) on location, saving vessel owners and their clients both time and money by reducing downtime, limiting time off-contract, and reducing or eliminating the need for expensive and limited dry-docking. 

Our highly trained divers can survey, inspect, repair and replace deteriorated underwater components, finding the best way to safely resolve potentially complex and costly problems with minimal impact on facilities and surrounding waters. 

We have years of experience completing in-water surveys and ship maintenance and are the only IACS class approved commercial diving company in Djibouti and the Horn of Africa.

  • Sacrificial anode installation

  • Keel cooler repairs and maintenance

  • On-hire and off-hire inspections

  • Non-destructive testing (NDT) and thickness readings

  • Underwater burning and weld repairs

  • Transducer replacements

  • Intake cleaning

Our highly experienced teams have years of experience assisting during dry-docking operations, and also have extensive experience conducting dry-dock maintenance such as in-water inspection, blanking and un-blanking, pump intakes etc.  



​When conditions are not suitable for diving, SG SALVAGE has the capability to conduct unmanned Remotely Operated Vehicle (ROV) inspections. 


Our state-of-the-art Deep Trekker DTG3 ROV has a depth rating to 200 meters (656 feet), Precision Thruster, Underwater GPS Positioning, 4K Ultra HD low-light camera and Manipulator Arm, and is quickly and easily deployable for a variety of tasks.
