The naming ceremony for Havyard Leirvik NB 099 M/V “Havila Venus” takes place in Fosnavåg, Norway on Saturday, Oct. 17th.
AHTS “Havila Venus” is a Havyard design, type Havyard 845.
This vessel is with its state-of-the-art hybrid propulsion system, modern hull lines, clean design class and exhaust catalysts the most environmentally friendly AHTS in the market.
On Sunday the 18th, from 2 to 6 pm Havila Shipping arrange “open vessel” where anyone who is interested may visit the vessel and take a closer look at its advanced systems.
Havyard 845 is a large AHTS with a power station of 18000 kW which via an advanced hybrid propulsion system provides high bollard pull, excellent ability for station keeping and ability to carry out advanced operations in extreme conditions.
The hybrid system is the most advanced and environmentally friendly on the market today and is super economic in all of the vessels operating conditions. In transit from A to B the power requirement is low compared to the vessels total power resource. In dynamic positioning mode for subsea operations in deep water the power requirement will vary, while demanding anchor handling operations will periodically require all available power.
The power station consists of two larger and four smaller diesel generator sets. The hybrid system enables optimising of different combinations of diesel mechanic and diesel electric drive. Advanced systems control the generator sets’ operating conditions for minimising fuel consumption and emissions of NOx and CO2. The advanced hybrid system on a Havyard 845 operates with 10-15 % lower fuel consumption than other solutions in the market today.
Powerful 500 ton AHT winches and equipment for safe anchor handling makes “Havila Venus” a safe working place with superior capacities for anchor handling and towing operations. Launch and recovery system (LARS) for operation of ROV’s over shipside in combination with A-frame on the stern enables the vessel to perform advanced subsea operations down to 3000 m.
A Box Cooler is a cooling system which finds growing application both for inland and sea going ships.
The unique characteristic of box cooling
Cooling water is forced through a U-tube-bundle, which is placed in a sea-chest having inlet- and outlet-grids. The cooling effect is reached by natural circulation of the outboard water in the sea-chest or by a circulation due to the speed of the vessel. The outboard water is heated and rises by its lower density, thus causing a natural upward circulation
