MARIN enters into long-term partnership with Dutch government’s Rijkswaterstaat

MARIN and the Rijkswaterstaat (RWS), which is part of the Dutch Ministry of Infrastructure and the Environment, have entered into a long-term partnership. RWS is responsible for the design, construction, management and maintenance of the main infrastructure facilities in the Netherlands.

RWS is an important government department responsible for flood prevention and nautical safety on the busy inland waters and on the Dutch Continental Shelf. Additionally it manages waterway capacity and spatial planning. Under the new agreement, MARIN is respon sible for the development and maintenance of tools to assess the maritime safety and capacity of the inland waterways and along the Dutch coast. MARIN will carry out safety modelling, including vessel manoeuvring behaviour and human behavioural aspects. Outside of the Netherlands, MARIN aims to develop safety modelling initiatives for international shipping and it is hoping to cooperate with its counterparts world wide, in order to define a common approach to the assessment of shipping safety.

Courses 2016

MARIN will organise the traditional courses for floating offshore structures and ship design at its Wageningen headquarters, in spring 2016.

Hydrodynamics of Floating Offshore Structures March 7-11, 2016 This annual course offers the opportunity to stay up-to-date with the latest developments in offshore hydrody- namics.

Hydrodynamics in Ship Design March 14-18, 2016 Hydrodynamics plays an essential role in ship design. In this course the various hydrodynamic aspects are presented and applied in a balanced and integrated way.

Unique public-private cooperation SLING tackles complex sloshing physics

Through the STW ‘Perspective Programme’, a unique public-private cooperation named Sloshing of Liquefied Natural Gas (SLING) has been established between five top ranking research groups, the international LNG industry, the Dutch shipping and shipbuilding sector, Dutch engineering companies and MARIN. SLING is a 5.3 million Euro research programme, which has a 3.45 million Euro grant from STW.

The Dutch government is aiming to reduce emissions and one way of realising a significant reduction is for ships and trucks to switch to liquefied natural gas (LNG) as an alternative fuel. In the coming years, significant investments are needed in the infrastructure for distribution of LNG (fuelling stations, feeders, bunker ships) and in new technologies to run ships and trucks on LNG. However, investments in the shipping sector lag behind. Cost re- ductions and safe technology are essential.

SLING is developing the knowledge needed for new technologies for LNG tanks with crucial cost saving potential. The key to | designing cost-effective LNG tanks is a shift to a first-principle approach to assess

sloshing impacts. Due to the motion of the ship, surface waves are formed in the tanks that impact the tank walls, which can damage the structure. SLING brings together an unparalleled, multidisciplinary team to tackle the complex sloshing physics through advanced experiments and numerical simulations. SLING establishes a new Dutch knowledge infrastructure with multiphase flow experts, state-of-the-art numerical tools and a unique multiphase facility.
