UNDERWATER PAINTING

We have developed an established process for the successful application of underwater coatings to vessels, subsea structures and offshore installations. Prior to the application of protective coatings below the waterline, all marine growth and surface oxidisation is removed by rotary disc preparation, with the steel substrate cleaned to SA 2.5 equivalent. Our developed process known as ‘sacrificial pre-treatment’ then allows applied paint coatings to wet out and bond to the steel surface in water. This process ensures that coatings applied in this way have a much better life expectancy. This service provides a proven waterborne solution for the ongoing protection of assets without the need for costly dry docking or off station periods, using a range of specialist materials including anti-corrosives, antifouling, fillers and adhesives.

Typical underwater applications include:

Re-preservation of detached coatings arising from mechanical damage, shell plate repairs or anchor chaffing
Application of protective coatings to jetty structures/offshore installations
Application of coatings to vessel block areas inaccessible whilst in dry dock
Re-preservation of subsea coatings arising from internal welding repairs
Re-instate hydrodynamic profile (adjacent to hull penetrations/transducers)

USE OF ADHESIVES UNDERWATER

We are also able to provide and apply adhesives suitable for bonding a wide selection of materials underwater for both naval and commercial customers. BPM products typically produce underwater tensile and shear joint strengths in excess of 15Mpa (+150kg/cm²)

Typical underwater applications we offer include:

application of sensor/monitoring equipment

Marine Eagle offers technically sophisticated solutions to propeller damage and associated performance problems via the One Ocean™ network. This network has been formed between UMC International, All-Sea Enterprises and Phoenix International to offer a global single common standard of service delivery.

Through this association, BPM is able to perform underwater ‘shop quality’ repairs, which, in many cases are considered as ‘permanent’ by the Classification Societies. The One Ocean™ network can now accomplish repairs underwater that, until recently, could be done only in propeller shops. BPM personnel have undergone extensive classroom and on-the-job training in propeller repair. This training has included operating specialized equipment and techniques that allow propeller blade straightening; mass in-balance correction and technical inspections.

EXPERIENCE SPECIALISTS

Experienced propeller specialists perform all repairs, and when necessary, a hydrodynamicist provides assistance and supervision. Repairs are usually accomplished at a vessel’s scheduled stop without causing delay or interruption.

We are able to provide the following:

Accurate identification of damage, including detection of micro-fractures
Establishment of hydrodynamic contour
Straightening (dry)
New blade tips
New Propellers
Blue fit of propellers and rudder stocks
Balancing of blades and fixed pitch propellers
Restoration of propeller mass and hydrodynamic balance
Contour modification to correct cavitations
Edge modification, including anti-sing correction
Correction of propeller-induced engine overload
ACFM (Alternating Current Field Measurement) detection for cracks
Super polishing to less than 1 micron
Afloat replacement of thrusters, propellers and blades
Global assistance at over 300 ports
