    What is the problem with communication in the Arctic?

    Since 2007 MARINTEK has run several projects investigating the status of communication at sea in the Arctic. From interviews, theoretical analyses and practical field tests we have learned that the current communication infrastructure is inadequate for the operational requirements of expected future maritime activities in the Arctic.

    Sea freight is the most economical and efficient means of transporting large amounts of goods and merchandise over long distances, and most transported cargo is carried by sea freight. The shipping industry is thus a major contributor to air emissions locally and globally.

    Shipping KPI reaches maturity

    Started by InterManager in collaboration with the Research Council of Norway, MARINTEK and Wilhelmsen ASA, the Shipping KPI Project has developed standard tools for measuring the performance of both companies and vessels. Now established as the independent, not-for-profit KPI Association Ltd, the project works with a wide range of industry stakeholders and aims to develop an industry-wide standard for vessel performance measurement.

    Energy management in practice

    In collaboration with Norwegian ship managers Grieg Shipping, Wilh. Wilhelmsen, Klaveness Ship Management, BW Gas and Solvang, system suppliers Kongsberg Maritime and MARORKA, and the Norwegian University of Science and Technology (NTNU), MARINTEK is continuing its research into ways of improving practices in vessel energy management via joint efforts in the EMIP II project.

  • Offshore service vessel for the Barents Sea

    Interest in oil and gas exploration in the Barents Sea region has increased significantly in the course of the past few years. MARINTEK recently completed a study of a vessel for all-year intervention operations on subsea oil and gas installations in the North-eastern part of the Barents Sea. An initial review of normal and abnormal intervention tasks was carried out with the aid of experts from the offshore industry. A business case was prepared and a vessel designed to meet open water and ice conditions for a specific field east of Svalbard.

    CFD modelling of marine propulsors

    The complexity of propeller geometry and the presence of rotational flows, with 3D boundary layers, strongly anisotropic structure of turbulence, high pressure gradients and fluid acceleration make the analysis of marine propellers one of the most challenging topics in marine hydrodynamics. Many numerical methods, with various levels of sophistication, are available and we describe their applications to the simulation of propulsor flows in this and the following sections.
