Live fish carrier II
A live fish carrier is a vessel designed to support breeding ponds and transport live fish to shore in best posibble condition. The use of low pressure fish pump and lice removing equipment aims at fish health.
Ship purpose
Main purpose of ship is to deliver fresh and healthy fish to the shore.
Secondary purpose is to support the breeding ponds by removing lice and to transfer fish from pond to pond for time of service work and cleaning.
Ship power supply and propulsion
Ship main power supply is based on diesel-electric system. Due to multiple diesel power generators the safety of the ship is increased. In case of one gen-set failure there are others that can work without any obstucles. Moreover in case of full blackout there is emergency generator that can supply power for the most important systems allowing ship to maintain maneuverability.
The ship movement is provided by electric engine that drives main shaft to propeller. The use of electric engine gives posibility to adjust the speed of rotation begining from 0. This helps to adjust vessel speed of fishing during various sea states. Additional help are hydraulic adjusting propeller blades.
The propeller is situated in Kort nozzle which besides of improvement in propulsion efficiency, protects rotating blades from debrie, shallow waters and in some casses from entanglement of fishing net.
The vessel is equipped with 3 thrusters, one forward and two at aft. To increase safety of ship and make operation easier the vessel use dynamic positioning system which consist of thrusters in combination with main propeller and positioning system that helps during slow speed maneuvering or during maintaining position.
The use of diesel-electric system is considered as ecological approach. The constant, designed rotation speed and load gives opportunity to lower the consumption of fuel and exhausted air pollution. The cooperation of multiple gen-sets can be a optimization subject of desireable parameters, in example fuel consumption, power or exhaust gas composition.
Environmental friendly
Bottom part of the hull will be painted with environmentally friendly paints that is non-toxic and copper free.
The use of hydraulic oils is a necessity, but we are aiming for the most eco-friendly products. So if available, the oil based on renewable, raw materials that are biodegradable, largely harmless from the eco-toxicology point of view and can be recycle, are our choose.
Vessel will be equipped with sewage treatment system, ballast water treatment system, oil and water treatment system. These not only reduce pollutants generated by ship, but also reduce neccessary vollume of tanks needed for storage used mediums to be handle on the shore for utilization.
During ballasting the balast water flows through proprietary filter. The filter removes larger organisms and particles and back flushes them overboard at the balasting location. After passing the filter, the balast water continues through the UV chambers on its way to the balast tanks. The UV light kills or inactivates organisms, viruses and bacteria in the balast water. During de-ballasting the filter is automatyically bypassed, and the balast water receives a second UV treatment during discharge as a safeguard to ensure compliance.
Addition to minimization the pollutants is the recycle of unused energy generated by diesel-generators in form of heat. The waste heat can be used in fresh water generators that can provide salt-free water that can be used in sanitary cabins, toilets and as a technical water. That not only be a ecological factor, but also a economical one as a fresh water tank can be of smaller vollume and gained space can be designed for larger cargo holds.
The use of diesel generator gives opportunity to use a better quality fuel that not only produce less pollution in form of sulfur oxides, but also give more energy output. To further increase cleanness of exhaust gases the nitride oxides can be dealt with be using urea injection system.
Accomodation
To provide decent conditions the crew quarters are of best quality. All living spaces are soundproofed to comfortable level and have full climat control system, as for common spaces, as for individual quarters. The furnishing and outfitting can be customized to individual requests or can be made as one standard. To make life on ship more social the common spaces are suited for large number of people and can provide entertainment, for example cinema or gym.
Fish transport & treatment
Our live fish carrier is equipped with large RSW tank, allowing the transportation of live fish in a gentle manner. Fish are pumped on and off the vessels using a fish-pump system, with a crane used to handle and position the fish-pump hose into the net cage. Marmus live fish carrier is also equipped with a mechanical de-licing system for fish treatment. We pay special attention to ecological aspects, which is why we do not use chemical methods, unless required by the customer.
Technical suport in design and building
The live fish carrier is designed to fulfill various requirements from client. The existing solution can be prepared to meet requirements of class, flag, conventions and other chosen rules. To make these possible the project is supported by multiple qualified engineers that can provide knowledge and expierience not only during design process but also during building in yard. That bridge between client and shipyard smoothen the process of construction but also helps in choosing the suppliers of most crusial components. Supervision of construction in yard gives also oportunity to solve problems without unneccery delays.
