During trials the correct measurement of metocean conditions is crucial for reproducibility, performance prediction and to avoid disputes between different stakeholders. MARIN believes its new C-DRONE can make it much easier to obtain accurate measurement data. MARIN has several systems in use to measure wave height and period. The most direct and accurate way to measure the wave characteristics is the use of a wave buoy. Yet, a buoy is rarely requested during trials because the retrieval process requires a separate support boat that can easily manoeuvre and pick up the buoy.

MARIN Opens Depressurized Wave Basin

Following a true maritime tradition, the new DWB was christened. The representatives and attendees each had a bottle filled with water from their own organisation or habitat symbolising their connection with the new facility. MARIN’s unique Depressurised Wave Basin (DWB) was officially inaugurated on March 19 by Maxime Verhagen, the Dutch Minister of Economic Affairs, Agriculture and Innovation. Representing the combination of a depressurised towing tank with a wave maker, the DWB creates a world first.

Containership Design

Seaspan Saver, a 10,000 TEU container vessel is setting new standards in container ship design. MARIN and Marine Design and Research Institute of China (MARIC) developed the hull lines of this unique vessel, which has been entirely designed with a low operational cost profile in mind. Canadian owner Seaspan requested a hull form that facilitates very low fuel consumption in the operational speed range, but at the same time it had to be able to keep an acceptable top speed. This approach is in stark contrast to previous ideas, which have focused on having the highest possible top speed.

Marine Hazards to Subsea Cables and Pipelines

In February 1989 the RoRo vessel Vinca Gorthon ran into heavy weather and sank off the Dutch coast. She landed on an oil pipeline that was severely damaged. Although the probability of sinking on top of a pipeline is very small, the incident showed that it can happen. Shipping traffic can represent a potential hazard to subsea pipelines in various ways, such as sinking or grounding, lost containers or an anchor hooking onto a pipeline. Over the years MARIN has contributed to the…

IRClass Offers EEDI Validation Service

IRClass (Indian Register of Shipping) has recently included Energy Efficiency Design Index (EEDI) validation to its service offerings. This is in response to the International Maritime Organization’s (IMO) adoption of the EEDI regulation on January 1, 2013 which will apply to the majority of vessels delivered on or after July 1, 2015. Under the regulation, the EEDI value calculated for a vessel must be based on speed in ideal sea conditions. However, often such conditions are not practically achievable due to time and geographical constraints.

Testing Breaking Waves vs. Offshore Wind Turbines

More than 60 representatives of the international offshore wind industry gathered last week at the Offshore Wind Seminar, organized by the Maritime Research Institute Netherlands (MARIN) and the Energy research Centre of the Netherlands (ECN). This seminar included a visit to unique model tests in the MARIN facilities of breaking waves against an offshore wind turbine. This pilot series of model tests, with a special model of an offshore wind turbine with realistic flexibility…

Quantitative Risk Analysis for LNG Terminals

Wim Lafeber

Widescale Development of LNG Bunkering is Expected. Lloyd’s Register recently conducted a survey that indicated that the majority of major ports around the world are either planning for, or are anticipating, the widescale development of LNG bunkering. One of the locations is the Port of Rotterdam, which is a busy port with dense traffic on the various waterways consisting of both maritime and inland vessels. During the analysis, the probability of ship collisions was assessed and then the consequences were identified.

Floating Wind Power: A Semisubmersible Floating Turbine Foundation

Floating foundations for wind turbines present some technical advantages, which is encouraging more and more industry players to develop new floaters. Firstly, they can be deployed in deep seas, independent of the soil conditions. Secondly, the installation and heavy maintenance can be done in sheltered areas, so that the whole OFWT can be towed directly to the wind farm’s location by conventional tugs. However, floating foundations also bring new constraints on the wind turbine due to their motions in waves and wind.

Efforts continue to improve the Modeling of Thrusters

Robert Heerkink is project manager at the Ships department of MARIN, the Maritime Research Institute Netherlands.

MARIN uses thrusters in many projects. For a typical model scale, around 1:50 to 1:60, relatively small thrusters are required. Thrusters for these models are available ranging from 50 mm to 80 mm nozzle diameters. In the past these thrusters were always modelled with a horizontal shaft. By tilting the nozzle, the closest possible match was achieved between the client specifications and the modelled thruster for the basin tests. Due to the ever-evolving process in improving the models, new thrusters were built witha 7-degree tilted thruster shaft.

Logistical Scenario Analysis for Hydrodynamic Applications

Jorrit-Jan Serraris

To calculate the operability of the whole logistics chain, rather than only individual operations, MARIN has developed the hydrodynamic scenario analysis program ScenSim. The uptime, or operability, of a specific operation can be calculated with existing methods and tools in different ways. However, each specific operation is often just a small stage in a long chain. When planning an operation a key parameter is to know the efficiency and duration of the operation. When the operation is a continuous process…

In April 2015, the European Union adopted a mandatory Monitoring, Reporting and Verification (MRV) regulation for CO2 emissions resulting from maritime transport. The MRV requires operators of large ships to monitor and annually report the verified amount of CO2 emitted on journeys to, from and between EU ports. Using basic input data (distance, fuel, time, cargo weight) and indicators the ship’s performance is determined and reported publicly. Over the past two years MARIN has…

“FS3” Motion-based Simulator for Dutch Navy

A two-year project is underway which will lead to the development of a Fast Small Ship Simulator. Driving a small, fast navy boat in heavy seas can be a real challenge. Effects of broaching, surfing, capsizing risk, slamming and planing put severe demands on the crew and the boat handling. It requires a well developed  skill-set to safely navigate  under various operational  circumstances. With these challenges in mind, a two-year project has just started  to develop a dedicated  training tool, which is currently known as the Fast Small Ship Simulator (FSSS) or FS3.

MARIN Sponsors Wind Turbine Design Challenge

Twenty-five international Ph.D. students and young researchers of the international offshore wind industry gathered last week at the floating wind turbine challenge, organized by the Maritime Research Institute Netherlands (MARIN) and International Network on Offshore Renewable Energy (INORE). At this event, seven teams had to develop a floating structure for a 1/100 scale wind turbine in only 24 hours. All participants were provided the same choice of basic materials (PVC pipes, foam blocks, weights, tapes) and had to build the models by themselves. The concept with the lowest construction weight in combination with the lowest acceleration at the nacelle would be declared the winner.
