editorial Dear Reader, 6 New Wagenborg vessels to take on challenge of


world’s harshest environments Report interviews Bob Derks, Director Business Development Royal Wagenborg Offshore about the company’s ambitious plans for these frozen regions.


9 Wagenborg’s new IMSV “SERKEBORG” instrumented


for ice trials MARIN’s Trials & Monitoring group equipped the “SERKEBORG” with an extensive monitoring system.


10 Into the Artic onboard the James Clark Ross In 2012 the ice strengthened research ship James Clark Ross left Iceland, set course


northwards and ventured into the Arctic. MARIN monitored the sea ice conditions and their impact on the ship’s course and station keeping capabilities.


12 IceStream JIP launches A pilot project evaluates ice flow control measures.


13 Numerical prediction of propeller loading due to sea ice As part of the Cooperative Research Ships (CRS) consortium, MARIN has undertaken


a project to better understand and predict loads on propellers in ice.


14 Ice crushing propeller dynamics revealed Report provides an update of the pioneering work of the PROPOLAR team.


16 Simulation training for operations in ice With demand for training for ice operations increasing, MARIN extends its ice


simulation capabilities. 17 Initiative to create Arctic Engineering JIP Week gains


momentum The quest for knowledge continues: various Arctic initiatives are highlighted.


18 Complete propulsion system simulation with


ReFRESCO Within the EU project STREAMLINE, the ReFRESCO team has developed new techniques facilitating advanced simulations of the complete propulsion system.


20 MARIN and Conoship propose changes to EEDI


regulatory framework for small general cargo ships The cause of the large scatter in the Energy Efficiency Design Index (EEDI) values of small, general cargo ships is investigated.


22 Geometry always at the heart of MARIN’s work Computational geometry is at the heart of much of MARIN’s day-to-day business,


which includes the hull, appendages, propulsion design and optimisation, to the milling of models and detailed CFD calculations.


23 Increasing demand for Vessel Traffic Simulation


training Over the past few years training VTS operators using the very latest simulation technology has become a core competence of MARIN.


I would like to welcome you to the first edition of Report in 2013 and wish you a very Happy and Healthy New Year. As many of you may have seen MARIN had a double celebration last year with its 80th Anniversary and also when we opened the new Depressurised Wave Basin. A very busy year was rounded off with a special Open Day where more than 4,000 visitors attended! And despite a slow world economy, MARIN is doing well thanks to your trust in our work.


If you are feeling a slight chill in the air that is probably because we have dedicated this issue to the Arctic, reflecting the increasing interest in this formidable and challenging region.


As the Northwest Passage becomes more accessible and oil & gas projects continue apace, MARIN wants to offer its maritime knowledge and expertise to assure this is done safely. We are working tirelessly with our customers and industry partners to increase our knowledge in ship performance in the Arctic and in the behaviour of offshore structures.


This year we are instrumenting Royal Wagenborg’s newbuild IMSV “SERKEBORG” for ice trials. In this edition, Bob Derks, Director Business Development Wagenborg Offshore, tells Report about the compa- ny’s fascinating work in the North Caspian.


In the near future MARIN intends to adapt the models for ice conditions and include this in the visualisation of the nautical bridge simulators. We are also developing a numerical engineering model for the flow of ‘managed’ ice around and under floating constructions as you will see in this edition. In order to develop our capabilities in this area we have established a cooperation with Oce- anic Consultancy Corp. of St Johns, Newfoundland.


If you have any questions or comments on one of the Arctic themes, please do not hesi- tate to contact the authors, they are happy to tell you more about their interesting work.
