An additional class notation expresses the classification of additional equipment or specific arrangement, which has been requested by the Interested Party (usually the Ship Owner). Additional Class notations are important to the ship-owner to show charterers and administrations that the vessel has been designed to have specific high technical standards. During the new building stage between shipyard and ship-owner can be used as a reference to a clear technical standard for the design and construction.
MOST OFTEN REQUESTED ADDITIONAL CLASS NOTATIONS
The goal-based, environmental friendly additional class notation, which allows design flexibility and rewards innovative technologies.
COMFORT ON BOARD
- COMF-VIB: defines the limits of acceptability of vibration on board, the methods for verification of compliance and the criteria for acceptance
- COMF-NOISE: defines the limits of acceptability of noise on board, the methods for verification of compliance and the criteria for acceptance
- COMF-AIR: to establish a number of climatic parameters that can satisfy the crew and passengers on a ship and the way to ascertain that the HVAC system of the ship is adequate
To recognize the use of LNG as fuel for propulsion and auxiliary systems on board as one of the most effective means of control of NOx
and particulate matter emissions from ships’ exhaust gas.
ROUTE DEPENDENT LASHING
The arrangement of container and their lashing is defined taking into account the ship accelerations calculated for the specific route the ship is engaged with, thus allowing their optimization without compromising the safety of cargo.
To indicate that the ship has been designed to comply not only with Ice Class requirements for strength and propulsion purposes, but also with measures aimed at ensuring her safe and effective operation at very low temperatures.
