With the soaring prices of bunker fuel, it is essential to keep your vessels performance at its peak. Our dive teams can perform any type of vessel maintenance service required, quickly and efficiently; in order to optimize vessel’s efficiency and reduce operating costs. Some of these services are as listed below.

Hull Cleaning

Featuring the most modern and effective hull cleaning brush-cart system available today, we can clean up to 2500 sq/m an hour depending on the type and severity of the marine growth. Our equipment is extremely portable and we can service your vessel anywhere along the east coast, as well as, ports worldwide. We are currently operating four cleaning machines which offer us great flexibility in meeting our client’s demands while also providing us with equipment redundancy.

Propeller Polishing

It has been well documented through many case studies that the effects of a poorly maintained propeller can decrease speed and power by up to 5 % compared to that of a propeller maintaining an “A” Finish on the Rupert Scale.

The annual cost savings of a 100,000 DWT tanker with a properly maintained propeller can be as much as $150,000 USD. With our high speed polishing equipment and specially formulated abrasive polishing pads our dive teams can complete multi stage micro polishings on the largest of propellers in usually four hours or less, depending upon the maintenance program of the propeller.

Anode Installation

While our dive teams are able to install all types of anodes quickly and efficiently by either bolt-on attachment or by underwater wet welding, we can also supply any type and numbers of anode required, on short notice, as we have long standing relationships with the local suppliers. In addition, we keep in stock, a large variety of anode configurations and material type (i.e.: zinc, aluminum, magnesium) for immediate installation. We also replace and install ICCP systems on a regular basis.

Rope Guard Fabrication And Installation

With our extensive inventory of rigging equipment and specialty designed hydraulic presses, our dive teams have successfully completed rope guard fabrication and large in-water rope guard change outs. In addition, we have recently purchased an International 4900 six-ton crane truck to assist us with the replacement procedures utilized on the USCG 110′ WPB’s, which we perform on a routine basis

Sea Chest Cleaning

In addition to full hull cleaning services, we perform the sea chest grids cleaning using hand tools to properly clean the gratings of all sea water inlets as required. In a special case, the sea chest gratings are removed when needed in order to clean the interior of the sea boxes with the gratings reinstalled and secured upon completion of the cleaning.

 

Executive Summary:

We have extensive experience with the underwater hull cleaning services performed by certified commercial divers using equipment and procedures fully compliant with the strict biofouling management standards of New Zealand’s Ministry for Primary Industries (MPI) and Australia’s Department of Agriculture, Fisheries and Forestry (DAFF). Our services are tailored for shipowners, port operators, vessel managers seeking to optimize vessel performance while adhering to international environmental regulations.

Key Differentiators:

✅ Full compliance with regional biosecurity and hull fouling protocols:
New Zealand: Craft Risk Management Standard for Biofouling (MPI)
Australia: Biofouling Management Requirements (DAFF)
✅ Commercial diving teams´ certified.
✅ post-service reporting including HD footage, inspection logs, and compliance checklists.

Scope of Services:

  • UW hull cleaning services alongside berth or at anchorage.
  • Biofouling removal from the whole hull of the vessel and the niche areas; Sea chests grids, Bilge keels, Bow/Stern thrusters, Rudders, Propellers, Discharge pipes, Bulbous bow, Rope guards, shafts, draft marks, Sounders/instruments, Sacrificial anodes, etc.

Notes: The sea chest gratings are removed in order to clean the interior of the sea boxes with the gratings reinstalled and secured upon completion of the cleaning.

  • Post-cleaning verification.
  • Issuance of specialized written report in compliance with the requested regulations.

“Improve your vessel’s hydrodynamic performance, reduce fuel consumption, and ensure compliance with biosecurity standards. We deliver clean hulls with specialized written reports.”

Operations fully aligned with:
MPI’s Craft Risk Management Standard (NZ).
DAFF’s Biofouling Management Requirements (AU).
