Gotar: Keeping Ships Clean From the Inside

Cruise Industry Annual

With a number of recent disease scares aboard cruise ships, the mandate to get and stay clean is monumental. Therefore, companies such as Gotar

Technologies have begun to focus more and more on the motto of which they are based, "Perfect chemical solutions for a perfect world."

The company, whose headquarters are based in

Quebec, Canada, also operates an R&D Production unit out of Saguenay, Quebec, and a U.S. office in

Houston (Friendswood), Texas. Manufacturing a diversified variety of cleaning products with a large range of applications, the company features a selec- tion of products, such as deoxidizers that eliminate lime and calcium buildup; degreasers that remove organic matter, oil residues and carbon deposits; and other formulas developed for a variety of metal sur- faces.

Gotar's products are touted as non-toxic, biodegradable and cost-effective, while extending equipment's life cycle. The Gotar product that has received the most coverage recently is Gotar D - a deoxidizer, descaler, which dissolves calcium, lime and other corrosive materials from steel, copper alloys and iron. The product was approved late last year by the U.S. Navy for use as its exclusive deox- idizing cleaning agent on its surface fleet.

Formulated to seek out ferrous and non-ferrous oxi- dation, corrosion and lime, Gotar D is similar to the company's Gotar AL, which is just as effective as a deoxidizer and descaler, but is designed for safe application on light metals, such as aluminum, mag- nesium and tin.

Regarding Gotar's degreasers and emulsifiers, these products are designed to attack oil residues, synthetic oils and grease, as well as carbon deposits.

Gotar DG completely dissolves organic materials, such as algae, mud and silt, in heat exchange sys- tems, while Gotar DGS is tough on synthetic lubri- cants, baked-on carbon and oil residues caused by friction. In addition, Gotar AGS delivers the same effective degreasing properties as DGS, but is better suited for light metals.

On the commercial side, mainly the cruise ship- ping niche, Gotar recently sent a technical crew to

Freeport, Bahamas to perform various deoxidizing functions on cruise vessel SS Sun. The 984 ft. (300- m) ship, which was built in France in 1964 at the time was undergoing a complete refit by its manag- er, International Shipping Partners, tapped Gotar to decalcify critical equipment such as evaporators, cooling systems, heat exchangers and boilers.

Using 10,000 liters of Gotar D, the deoxidizing was performed within the equipment (containing 800 tubes) with a 15-hp pump in a closed circuit operation. With more than 2,000 liters of Gotar D used to fill the 30 x 16-in. exchanger, the entire process was completed successfully within four hours.

Another answer to a problematic situation by

Gotar was performed on Groupe Desgagnes' vessel

N/C Melissa Desgagnes, which required a clean up of its cooling system. Subsequent to coupling hoses on the entry and outflow of the vessel's cooler, Gotar

D was circulated by maintaining a cycle that alter- nates rest periods and circulation periods during three hours — enabling Gotar engineers to clean thoroughly the inside of the cooler.

Coral Princess Debuts With Unique Propulsion System

Coral Princess' propulsion system is the first in the cruise industry to fully utilize a new development of the diesel engine known as an

EnviroEngine, as well as the first in the Princess fleet to incorporate gas turbine power generation. This inno- vative combination uses technology proven to be both highly efficient and environmentally sound, and, in a unique design development where the gas turbine is installed in the ship funnel, provides additional space for a wider range of public rooms and onboard facili- ties.

Coral Princess is powered by one gas turbine that operates in conjunction with two diesel

EnviroEngines.

The turbine replaces at least two diesel engines and by using two separate power systems, this unique one- of-a-kind configuration is designed to create a reliable and safe energy source.

Described as the most environmentally friendly and economical way of using fossil fuel for power production, the

EnviroEngines, manufactured by

Wartsila, were developed in close cooperation with P&O Princess

Cruises.

Representing state-of-the-art diesel engine technology, EnviroEngines employ common rail fuel injection technology that results in smokeless operation, producing a clear engine exhaust and direct water injection to reduce NOx.

Princess is also the first cruise line to install a gas turbine in its ships' funnel; a positioning that creates a technological challenge never before undertaken. This unique placement frees up significant additional pas- senger space — used to incorporate more public fea- tures into the ship's design. As a result, Coral Princess passengers will enjoy the benefits of two lower decks dedicated to public amenities where most other ships offer only one.
