Thalatta 

Thalatta 

This new generation High Efficiency Ro-Ro (HERO) vessels, designed for the new wider Panama Canal, offers a capacity of 66.120 m2 deck area. This can be utilised for loading of just above 8,000 RT units, assuming 8.2 m2/RT.

This new generation of PCTC vessels for Wallenius Wilhelmsen Logistics Round the World Liner Service (RTW) is designed for efficient transportation of mainly cars and trucks.

Major design objectives: Low fuel consumption, good transport economy, efficient and safe cargo handling, minimum environmental impact, good form stability and thus reduced need for water ballast.

 General Arrangement
The vessel is arranged with engine room aft. Mooring decks forward and aft, respectively on deck 7 & 8. The living quarters in two tiers on the weather deck. The wheelhouse is designed for optimum visibility for the officers on bridge.

Fuel oil is carried in protected deep tanks forward and aft of the cargo hold.

A pipe tunnel containing all ballast and fuel piping & valves is arranged in the double bottom. 

Cargo hold
Clear heights and deck strengths as per WWL requirements and the enclosed Cargo hold Midship section drawing. Deck 1, 3 and 5 to be strengthened for forklift handling of flatbeds, pallets and break-bulk cargo.

The cargo hold is laid out with single pillars as far as possible while double pillars are used in the aft part of the vessel (abt. 1/3 of the cargo deck area).

Machinery
The vessel shall be powered by one electronically controlled slow speed, two stroke main engine and propelled by a single fixed pitch (FP) propeller.

M/E  

 MAN B&W 8 cylinder S60ME-C8.

NCR  

 14.000 kW @101.4rpm

MCR  

 15,560 kW @ 105rpm

Propeller  

 4 blades, 6.9 mm diameter

In order to reduce the fuel consumption and emissions, a larger engine was selected and then de-rated to achieve lower specific fuel oil consumption. In addition, the engine has a low load tuning by the means of exhaust gas by-pass, in order to optimise the consumption, when running at part load/low load.

The main engine is also equipped with a modern lubrication system. In addition, sensors are installed to monitor temperature & ware on crank pin bearing, cylinder wall etc to minimise the risk of engine breakdowns.

Power generation on board will be by the means of auxiliary generator sets (3 off).

Auxiliary generator set  

 2 x 1900 kWe

Auxiliary generator set  

 1 x 1600 kWe

Emergency generator

 

 250 kWe

The design and machinery installation is based on SOX-removal by an Exhaust Gas Cleaning System (scrubber), avoiding the need for using more expensive MGO and double fuel oil supply, transfer and service systems. This alternative will also eliminate risks related to fuel oil switching. The EGCS will enable the vessels to comply with forthcoming new ECA regulations in 2015 and 2020 respectively.

One bow thruster is provided for improved manoeuvrability.

 

Classification

The vessel shall be built to Malta flag and under survey of DNV-GL with the following class notations

+ 1A1, Car Carrier RO/RO, MCDK, PWDK, E0, TMON, BWM-T, COAT-PSPC (B).

The vessel shall also be constructed to comply with the following DNV-GL class notations as to improve the design:

BIS, FUEL, CLEAN, NAUT-AW, F-AMC

 

Environmental initiatives

The vessels shall be delivered with a statement of compliance with IMO guidelines of ship recycling (Res a.962(23) issued by the classification society (Green passport).

The hull lines are optimised to give minimum resistance in calm water and waves. Necessary hull optimisation and model tank tests have been undertaken to ensure optimum performance over a range of draughts and speed ranges, reflecting the anticipated operation profile.

The ship is equipped with an Exhaust Gas Cleaning System (EGCS), in order for the vessel to meet the new ECA requirements on sulphur emissions. At the same time, the EGCS will contribute to reduce the particulate emissions up to 70%.

A Ballast water treatment is installed to meet the new standards entering into force once the Convention is ratified, which is expected any time.

The bilge water separator will only permit less than 5 ppm oil in water discharge, which is an imposed environmental friendly standard in our new building fleet.
