Designing efficient vessels is the heart of what naval architects do. Efficiency in this case is defined as the ratio of useful travelled distance of goods or cargo; divided by the total energy put into the transportation propulsion means. In other words, a more efficient vessel design will require less fuel (cost) to move a given cargo a certain distance. This paper will explain why efficiency is important and will explore some aspects of small coastal vessel design that can improve vessel efficiency. We will also investigate several of the techniques that are used to analyze a vessel’s efficiency utilizing Articulated Tug-Barge (ATB) units as case studies.
In the marine market, tight deadlines and budget constraints are common obstacles to overcome. Even finding a qualified welder for a marine application is a challenge, so being able to join pipe without flame can make all the difference in the marine world. Reducing time spent on repairs and labor expenses means you can focus on doing your job and keeping your crew safe. However, when dealing with a work environment that involves floating on a volatile sea, it can be difficult to ensure safety and precision while operating ocean-based support vessels, drill ships and oil platforms.
By operating on both land and water, marine repairers and equipment installers tackle a variety of tasks from general maintenance and repair, to upgrading and installing state-of-the-art systems and equipment. Along with these tasks comes a wide array of maritime risk exposures, both large and small, which the business owner needs to adequately address.
Anything can happen on a jobsite. Your equipment could malfunction or the weather might cause a whirlwind of unexpected issues, or even worse, someone could get hurt. Unfortunately, not much can be done when circumstances such as those arise, which is why developing preventive strategies is crucial to having a successful and safe project. One of those strategies is always choosing safe and reliable lifting equipment. But the question that remains: is it safer to rent or to buy?
There are numerous factors that are driving global environmental regulatory growth and the growth in renewable lubricant technologies, such as natural resource constraints, standardizing requirements due to globalization, public opinion and pressure, increase in climate change concerns, new technologies, new evidence from research and overall growing Environmental Health and Safety (EHS) concerns, and most recently the improvements in the durability of lubricants made from renewable technologies. According to environmental consultants and advisors, there are currently thousands of new environmental regulations awaiting attention from legislators and regulators around the globe. Different standards hamper growth and thus, pressure to harmonize regulations is likely to continue alongside the regional and global integration of markets.
Accurate, on-the-spot measurement of marine bunkering is critical for both cost control and relationship management. The Micro Motion® Certified Marine Bunker Measurement Solution (CBMS) provides highly accurate data plus a bunker ticket that is available immediately after the bunker is complete. Depending on the implementation, the bunker measurement is certified by Nederlands Meetinstituut (NMi), the notified body for testing to the guidelines of the European Instruments Directive (MID) and Issuing Authority for OIML (International Organization for Legal Metrology). The Micro Motion meter meets the OIML standard R117-1 and the overall solution meets MID Directive 2004/22/EC Annex MI-005.
Even the smallest hydraulic system failure can be very costly in terms of lost productivity, change-out times and repairs. This is compounded in large-scale operations, such as oil rigs or dredging sites. When a hydraulic system failure occurs, it is commonly blamed on the oil or hydraulic fluid being used, and rightly so, since it is estimated that 90 percent of the time a fluid-related pump failure is due to contamination. However, rather than simply questioning the quality or performance of the fluid itself, it is important to examine HOW the contamination occurred, what might have been done to prevent it, and to use this information to mitigate potential future problems. According to original equipment manufacturers and tribologists, the number one cause of hydraulic system failure is water contamination. Through a series of chemical reactions, the presence of water in the system builds a corrosive environment, which shortens the life of the pump or other equipment. While it is impossible to prevent water from getting into your system, there is a series of procedures and protocols that maintenance professionals can implement to measure the amount of water in the system and work to remove it before a failure occurs.
Servitization as a business strategy is sweeping through most industrial sectors. It has benefi ts for all parties on the sell side and buy side. For the manufacturer it provides competitive differentiation, deeper relationships with customers, enhanced customer satisfaction and loyalty, and a source of recurring revenues. For the customer it provides more value for the money and lower cost of ownership, as well as faster and better after-sale service and support. It is clearly the wave of the future in business relationships, and the time is right for the maritime industry to climb aboard.

In Japan, there is a maritime industry cluster of businesses, which include ship owners, shipbuilding companies and ship machinery and equipment makers. New products have been developed, while others have been improved within the framework of this maritime cluster. Japan has completed many vessels of a wide variety of types for years. Boasting high levels of performance and quality, Japan-built ships are highly rated by ship owners worldwide.
Accurate, on-the-spot measurement of marine bunkering is critical for both cost control and relationship management. The Micro Motion® Certified Marine Bunker Measurement Solution (CBMS) provides highly accurate data plus a bunker ticket that is available immediately after the bunker is complete. Depending on the implementation, the bunker measurement is certified by Nederlands Meetinstituut (NMi), the notified body for testing to the guidelines of the European Instruments Directive (MID) and Issuing Authority for OIML (International Organization for Legal Metrology). The Micro Motion meter meets the OIML standard R117-1 and the overall solution meets MID Directive 2004/22/EC Annex MI-005. During a meter trial, the Micro Motion system is frequently compared to the existing volumetric system, or to the volumetric system used by the other party. The comparison typically yields discrepancies that mistakenly call the new system into question. This white paper provides a brief overview of the Micro Motion Certified Marine Bunker Measurement Solution, then examines all the sources of measurement discrepancy and demonstrates that the apparent issues can be caused by a combination of the inherent uncertainties in volumetric measurement and inconsistent bunkering procedures. When appropriate bunkering procedures are followed, the Micro Motion system provides superior accuracy and should be used as the standard. The use of mass flowmeters (MFMs) is becoming standard practice in the transfer of marine fuel. The Marine Port Authority (MPA) of Singapore, which represents a large share of the global bunkering market, announced in April 2014 that the use of MFMs would be mandatory by the start of 2017. MFMs reduce the number of quantity disputes, eliminate time spent performing sounding operations before and after the delivery, and provide suppliers with powerful diagnostic tools for improving their processes. In addition, the MFM can provide the user with additional process metrics that help to prove the accuracy of their delivery quantities as well as their product quality. It is easy to see why MFMs are becoming the industry standard. ExxonMobil Marine Fuels & Lubricants was the first bunker fuel supplier in the marine industry to use a MFMS that has been approved by the Maritime and Port Authority of Singapore for bunker fuel deliveries.

When the Environmental Protection Agency (EPA) issued the new Vessel General Permit (VGP) in December 2013, lubricant and fluid manufacturers were prepared to give vessel owners a number of environmentally acceptable lubricants (EAL) to work with. EAL usage is now essentially required for any application on vessels where incidental lubricant discharge could occur in the marine environment. Those applications include stern tubes, thrusters, stabilizers, CPP propellers, and wire rope and mechanical equipment immersed in water during normal operation.
