Washing Each cargo tank is fitted with two fixed Scanjet tank washing machines for cleaning purposes Washing water is available from an industrial water tank in the engine room If required the water can be heated up to 60 degrees Celsius via a heat exchanger The tank washing pumps allow two wash two tanks simultaneously Additionally, every tank is fitted with a tank washing/vent hatch used for the portable tank washing machines of which two are available A Smit Gas nitrogen generator is installed in the engine room, supplying to a nitrogen storage vessel on deck settings 0.2 kg/sq.cm pressure and 0.035 kg/sq.cm vacuum Each cargo tank is provided with a hydraulically driven variable speed Framo SD 150 deepwell pump placed in a recessed well The centrifugal type cargo pumps, have a capacity of 335 cu.m/h each The total maximum loading capacity is 2,010 cu.m/h The total maximum discharge capacity is 2,010 cu.m/h (with six pumps running simultaneously) The maximum filling rate per tank is 400 cu.m/h (800 cu.m/h per tank pair) The cargo piping system is executed in stainless steel 316L designed for maximum velocities of m/s The cargo valves, make Econosto, fitted in the cargo system, are remotely controlled with hydraulic operated actuators from Danfoss The design pressure of the cargo system is 16 bar A Framo SD100 deepwell slop pump is installed in the sloptank Capacity

ship’s centerline All cargo pumps are executed with a stripping system, connected to the stripping lines leading to the cross-overs at the manifold This configuration results in excellent stripping performance The cargo piping system includes seven crossovers, one for each pair of tanks DN200, including slop tank DN100 Additional two common main crossovers are installed size DN350 and a vapour return connection Each manifold is fitted with: – Sampling point – Pressure indicator (with readout in CCR) – Temperature indicator Furthermore one HFO bunker filling crossover and one gasoil bunker filling crossover are located at the manifold A ballast water connection is also available at the manifold The cargo piping and treatment installation was carried out by Royal Niestern Sander designed to circulate cargo by means of the cargo pump through the deck heater and via the dump line back to the tank Design criteria include: – Heat up capacity of degrees Celsius\24 hours – Maintaining cargo temperature of 65 degrees Celsius Cargo Tank Monitoring & Level Alarm System Each cargo tank and the slop tank are fitted with: – Tank radar system make Saab – Temperature sensors at two levels – Pressure sensor – Closed sampling/ullaging connection – High level alarm (95%) – High level alarm (98%) All sensors are connected to a Saab cargo monitoring computer with backup system in the cargo control room Padding/Purging A nitrogen generator, make Smit Gas is installed in the engine room with a Nitrogen (N2) storage vessel on deck for cargo padding or purging of cargo and stripping lines The generator has a capacity of 825 cu.m/h, at 95% pure nitrogen The system outlet pressure is bar The working principle of the system is as follows: a screw compressor is extracting ambient air from his surrounding The air is led through several filters to remove dust, moisture and oil particles After this pre-treatment the air is led into the actual membranes where the compressed air is separated into streams of enriched nitrogen and enriched oxygen The principal allowing this separation is the differential permeation rate of various gases through the polymer membrane In the case of the membranes onboard of the ’Adour’, the membrane employed permeates oxygen and water vapour faster than nitrogen Because of this phenomenon, the oxygen and moisture components of air concentrate in the permeated gas (that portion that passes through the membrane) The remaining nitrogen rich gases will leave the membranes as a dry product stream On board the ’Adour’ the nitrogen is supplied from the membranes to a storage tank and divided into two supply lines from there One line is used for stripping of the cargo pumps at a pressure of bar The other line leads to the cargo tanks at a pressure of 0.2 bar The complete nitrogen system is incorporated in the vessel’s control system, but can also be operated locally View of the main manifold situated amidshaps on main deck Cargo Tank Heating Each cargo tank is fitted with a deck heater for cargo heating The heat exchanger is fed by the secondary thermal oil system The system is HSB INTERNATIONAL JANUARY 2003 L Ballast System Two Framo ballast pumps, each with a capacity of 450 cu.m/h are installed with a separate ballast stripping system The ballast system is remotely controlled from the cargo control room, including tank level indication The ballast tanks are fitted with a gas detection system with monitoring read out in the cargo control room The stability of the vessel during loading/unloading with ballasting/deballasting at the same time is sufficient to allow all cargo tanks and ballast tanks to be slack Propulsion Plant The main propulsion system consists of a MaK 6M43 main engine developing 5,400 kW (100% mcr) at 500 rpm The main engine runs on HFO IFO 380 cSt and is connected to a reduction gearbox via a flexible coupling make Vulkan Rato The reduction gearbox, make METSO (Valmet), is a
