How to achieve ship operational efficiency while maintaining compliance
It has become quite a difficult job to obtain a high efficiency of a ship in today’s time. It becomes challenging to achieve the optimum level of operational efficiency, even though a ship is meant to carry cargo efficiently. Various factors, such as the changing environment, workforce, and the economy, keep becoming a hurdle.
But still, it becomes harder to point out the precise point of efficiency loss. However, in this article, we will see how we can achieve ship operational efficiency while maintaining compliance. Let’s take a look.
When it comes to efficiency, a significant role is played by the design of the ship itself. After all, the design and structure of the vessel become the very base for its transitional and operational efficiency. Inclusion of highly efficient power trains and marine engines, and installation of optimized flow profiles around the propellor, rudder, and hull adds to the technical measures to have more productive outcomes. It is essential to understand that systems such as propulsion machinery, heat recovery, auxiliary machinery, hull construction, and so on all affect one another. Understanding these relations will prove in creating a design that is better and more efficient.
Containing a considerably lower percentage of nitrogen oxide and sulfur emissions, LNG can be considered the primal fuel choice when it comes to shipping. However, on the downside, LNG requires a lot of storing space, which has led the industry to look for other viable options. Research on harnessing the energy of wind and solar power is undergoing. Usage of different synthetic and alternative fuels, such as dimethyl ether, methanol, and so on is being tested for a greener option. With a more fuel-efficient option, it is natural for the over efficiency to increase.
It is important to define and benchmark the efficiency if we are looking at improving the efficiency of the ship. It does not just give us a target, but also lays out an elaborate basis which can be used for comparison. Some benchmarks are as follows:
- Propellor efficiency= Thrust HP/Delivered HP
- Engine efficiency= Delivered HP/ Fuel Consumed
- Propulsive efficiency = Engine x Propellor x Hull
These benchmarks play an important role in the designing and construction of the ship.
To increase efficiency, other than ship design and an alternative fuel choice is by implementing operational measures. It can be done by inducing precise communication between vessels for the planning of the route, operation planning in slow speed, and resource utilization of higher capacity. The reduction of turnaround times may also increase ship efficiency. Other ways include thorough cleaning of hulls, engine turning, and propeller polishing.
With that, we can put it forward that various factors of the ship management system together can increase the efficiency of the vessel. From the design of the ship to the fuel, technicalities, and various operational measures can indeed give a better and higher operational efficiency in shipping.
