Arctic (& Wind) Operations: Hands Across the Water

Renderings of the proposed Aeolus wind support fleet

As the North American offshore wind model evolves, it is clear that fit-for-purpose, Jones Act compliant and Arctic ready tonnage will need to be part of the equation. If so, we’ve got that box checked, with a little help from Europe.As of September 2018, the Walney Extension off the United Kingdom is the largest offshore wind farm in the world at 659 megawatts. There are at least 70 major wind farms, each with hundreds of wind turbines, each generating as much as 10 megawatts in offshore England, the North Sea, Russia and China.

C-Job Naval Architects has delivered the design for a wind-assisted general cargo vessel to Dutch shipping company Switijnk Shipping. The 8,500 DWT vessel will be equipped with two Norsepower Rotor Sails that will supplement the main engines and is expected to achieve fuel savings of approximately 14 per cent. C-Job was approached by Switijnk Shipping following its involvement in the European Union Interreg project S@IL, for which C-Job developed the earlier design of a 4,500 DWT Flettner Freighter. C-Job designed this smaller vessel with four Rotor Sails.

Eye on Design: C-DRONE

(Image: MARIN)

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.

Supporting Silent Ships

Have you ever had problems talking to someone in a noisy environment such as a busy restaurant? The same happens to marine animals, which use sound to sense and interact with their environment: for communication, navigation, finding prey and even for self-defence. High ambient noise levels, which include a contribution from shipping, have an adverse impact on marine life. The world’s oceans are becoming increasingly noisy. While the size of the global commercial fleet more than doubled since the 1960s, anthropogenic noise in the oceans has actually increased eightfold.

MARIN is working together with the industry to develop the Nautical Safety Profile for operations and risk management. Liquefied natural gas (LNG) is increasingly being used as an alternative fuel, both at sea and on land, to reduce pollution from transportation. In 2011 the first LNG carrier arrived at the Rotterdam Gate terminal, and last year the terminal was upgraded to facilitate the transfer of LNG to shuttle tankers. An extensive safety analysis was carried out prior to the development of the terminal and a dedicated harbor access policy has been defined.

Marine Hazards to Subsea Cables and Pipelines

(Image: MARIN)

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…

Bilge Keel Damping from In-field Motion Measurements

Chevron and MARIN worked together on a novel approach to characterize the actual damping for an FSPO in real world conditions. Results show that using damping from model tests means that roll decay in calm water is conservative and that natural roll periods are less sensitive to the FPSO draft than often considered in the design phase. Due to the resonance behavior of roll motions, roll damping is an important consideration for vessel motions and the associated extreme and fatigue loading on the hull, topsides and risers of an FPSO.

MARIN (Maritime Research Institute) tested an innovative concept for a floating mega island. The island comprises 87 large floating triangles that are flexibility connected to one another. Together they form a flexible floating island that can be as large as 1 to 5 km in cross-section. Olaf Waals, project manager and the concept developer: “As sea level rises, cities become overcrowded and more activities are carried out at sea, raising the dikes and reclaiming land from the seas are perhaps no longer an effective solution. • Building houses and recreation close to the water.

Naval Design: The Human Role

(Photo: MARIN)

Many navy new building projects face a double challenge; the variety and complexity of operations are increasing, while at the same time, a reduction in manning is a prerequisite in order to lower building and operational costs. Therefore, it is important to identify the required number and type of crew and the supporting systems in the concept phase. For a long time the use of weapons and platform systems have relied on a high degree of integrated, multi-sensor data processing and decision support systems.

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…

Lifetime Assessment for Deepwater Moorings

Photo: SBM Offshore

Mooring integrity is an important concern in the offshore industry [1]. Mooring leg failures can have  significant consequences, such as temporary shutdowns and require unplanned, thus expensive, repairs. On the other hand, an over dimensioned design leads to higher loads acting on the floating facilities and a large investment. Meanwhile, the development of deepwater projects has led to the discovery of the new fatigue mechanism of ‘Out of Plane Bending’ [2]. This means that the design of moorings requires more detailed analysis to ensure the integrity of the mooring system.

Measuring Noise Levels of Cavitating Propellers

Figure 1: Cavitation pattern on the propeller of the research catamaran

As underwater radiated noise levels in the oceans increases, MARIN has investigated just how much cavitating propellers are to blame. Traditionally, underwater radiated noise is mainly of interest for naval vessels and fishery research ships. Nowadays, however, there is a growing concern that marine life is affected by the rise in background noise levels in the oceans. Marine mammals and fish use sound to communicate and to sense their environment and this requires low background noise levels. The rise in noise levels is being caused by an increase in shipping, among other factors.
