SSESCo's main core of activity is providing Underwater Commercial Diving Services to the Marine & Offshore field since 96. We have the capability of carrying out Air diving to Saturation Diving as per clients requirements and jobs scope and we have our very own certified equipment to compliment the same.
Marine fouling is a perennial problem for Vessels, Ports, Jetties, Rigs, Offshore
Platforms, not necessarily stagnant for a brief period of time.
The Ocean is teeming with the tiny larvae of marine organisms, that swim around until they find somewhere to settle and grow. Smooth surfaces are particularly attractive to many of these creatures, and are quickly encrusted.
This can slow ships creating drag force which increases fuel consumption, blocks sea chests resulting in the overheating of water cooled compressors and generators and it speeds corrosion, resulting in faster aging of our offshore assets and vessels, all leading to vessel downtime or increased dry docking schedules, increasing costs.
THE WHY OF PERIODIC MAINTENANCE OF VESSEL HULLS ,RIGS,SBMs & STAGNANT MARINE STRUCTURES
Barnacles attach themselves to the surface by cement glands.
If this goes un-checked, this secretion dissolves the coating and the
barnacle attaches directly to the bare surface.
When the barnacle is removed, by whatever means, the paint will be
gone. With a little practice, the stalk or foot of the barnacle can be left in place if that is desirable between the lesser of 2 evils.
This will leave the surface somewhat protected but will increase drag
when the vessel is underway. This drag will decrease speed and increase fuel consumption by 15 – 25 %. MGR is mandatory to be carried out on vessels to maintain operation effectiveness.
A better alternative is to clean the surface of the vessel more frequently – before the adult barnacles develop.
MARINE GROWTH REMOVAL EQUIPMENT USED TODAYS
In today's market, there are a variety of underwater brush carts
available, depending upon the requirement of the client.
From light growth marine fouling to soft moss to semi or very hard
barnacles often measuring to about 3 inches in cases of stagnation of the vessel for a long time.
The bigger brush carts clean upto a rate of 1500 m2/hr or 25 m2/min
on mid sized barnacles and can operate to a max depth of 70 msw.
SEASWIFT'S PREFFERED MARINE FOULING REMOVAL EQUIPMENTS: THE CAVIBLASTER
The CaviBlaster is not just a "simple high pressure portable machine.
It's a State-Of-The-Art unit which uses low pressure and high volume whereas a water jet uses high pressure and low volume, often ranging from 10,000 to 20,000 psi.
Additionally, the cleaning is accomplished by the forces generated during implosion of the cavitations voids - not by the mass and energy of the high pressure water jet.
That's why the CAVIBLASTER method does not harm the diver or remove the paint.
Propeller fouling generates energy losses of up to 10% - 15% requiring additional power (fuel) to maintain the same speed. A rough rudder causing additional turbulence reduces the ves- sel's speed up to 2%.
The maintenance of propeller blades & rudder in a good condition has significant benefits for a vessel's fuel consumption, as well. Polishing the propellers offers power savings of between 10 to 15 % depending on the degree of fouling prior to polishing. This job we offer at no cost, if pro-rated with the complete hull cleaning of the vessel/structure/rig/floater/semi-submersible, using our CAVIBLASTER & PROPELLER POLISHER.
In Water Surveys
In Water Surveys or IWS is an acceptable method of surveying the underwater parts of a Rig, vessel, other while still afloat.
Our divers have the necessary experience for carrying out these surveys in the safest and quickest manner possible.
The reports generated by us adhere to world class standards and are accepted by all class agencies under IACS.
NDT Techniques find application in quality control and the assessment of deterioration of underwater appendages & structures.
The defects and damage may include cracks or thickness gauging or even anode wastages.
We at SEASWIFT have the necessary NDT Equipments to carry out surveys under the watchful eye of IACS Societies.
