Gulf Marine Management’s tanker Venus Glory, newly delivered from Daewoo shipyard in Korea, is the first vessel to carry the DNV class notation Nauticus (Newbuilding, Operation). This means that the ship has been entered into the Nauticus information database, and a 3-dimensional graphic model has been created. The information database will follow the ship throughout its life, and be available for the shipowner or operator at any time, anywhere, through the Internet.
Today we are visiting the yard with Øystein Goksøyr, responsible for Nauticus sales support at DNVs Pusan office. We tour the impressive yard, site of the worlds largest dry dock, 530m long.
Nauticus newbuilding
The Nauticus newbuilding notation means that the vessel is built according to this newbuilding standard. It signifies that the vessels strength has been verified by finite element analysis and extended fatigue calculations. The Nauticus Hull software programs are used for the design calculations, and a 3-D information database is created for the vessel. This database is continuously updated during design, construction and operation.
Venus Glorys second Nauticus notation, Operation gives the owner or operator of the ship access to the Nauticus information database. Examples of data available in the database are the 3-D graphic model of the vessel, electronic drawings and survey reports, re-coating calculations, steel replacements and repairs.
The 3-Dimensional Graphic Model is the Nauticus-generated 3-D model of the vessel. During the newbuilding phase the model is used as basis for finite-element and rule check analysis. In the operational phase it acts as information carrier for the Nauticus database. Nauticus Hull is a software program used for examining the hull design according to DNVs rules for structural strength. Finite Element analysis is used for direct strength calculations of the ships cargo area, with clearly defined loads and acceptance criteria.
Goksøyr explains all this simply: Nauticus gives the best foundation for a life-cycle approach to ship construction and operation. We work closely with Daewoo on Nauticus, creating a win-win situation for all involved - the yard, the shipowner or operator and DNV.
Practical application at Daewoo
Ship design underpins the performance of any shipyard. Daewoo is no exception, and its design department has some 600 employees. The design organisation is in two divisions: one for hull design, the other for outfitting design, under the control of Moon-Kyu Lim, Daewoo Senior Executive Managing Director.
Design department manager Seony-Ki Kim is an experienced user of Nauticus Hull. Switching on the workstation computer at the yard he demonstrates the use of the program. He is particularly pleased with the Nauticus Hull Rule Check program package. Even vessels not built to DNV class are checked with this package at Daewoo. Other Nauticus features are also utilised, such as finite-element and hydrodynamic analysis programs.
Nauticus for the future
DNV has invested heavily in software and IT solutions and this is now starting to pay off. The new Nauticus on board program delivers our class services for the future. DNV has redefined the value of ship classification by putting its accumulated knowledge and employees competence into Nauticus. This makes it more than just an IT-system it is DNVs new maritime culture.
Venus Glory signifies a new age in shipping. It is the age of instant input and feedback anywhere and at any time. Nauticus will further enhance safety at sea as well as ensure peace of mind for the shipower.
