Environmental protection and energy efficiency
The SCF Group fleet operates worldwide, so the issue of environmental protection is a global one for the company. We are aware of our responsibility and strive to minimize the impact on the environment through innovation, control over energy usage and staff retraining.
Despite the fact that the maritime transport is recognized as the most environmentally friendly in comparison with transportation by land and air transport, society expects permanent pollution reduction from ship owners. Therefore, the company is ahead in development and introduction of new methods of environmental protection, taking into account the strictest regional standards, often exceeding those stated in the Convention.
The environmental management system of SCF Management Services (Dubai) Ltd. is certified by the DNV GL classification society, for compliance with the international standard ISO 14001:2004, which is regularly confirmed by inspections at its offices and in the fleet. In addition, the company holds the Green Award certificate, which confirms its compliance with the best international practices for navigation safety, quality of service and environmental protection. SCF Management Services (Dubai) Ltd. was last inspected for compliance with Green Award standards in December 2016.
Initiatives to use renewable energy and energy efficiency (main events):
- Usage of the Slow Steaming mode on the ships for fuel consumption and emissions reduction. Economy results show that the transitions at low speed (7-9 knots) when the main engine loads less than 40% MCR increase energy efficiency and environmental safety of the vessels. The S3ES-Novoship programme includes a Slow Steaming Monitoring & Analysis section which allows ship operators to plan and monitor these modes of vessel operation;
- usage of trim difference for each vessel during the ballast voyage in order to achieve a minimum fuel consumption of the main engine (used on the company's ships since 2009). Optimum planting was established for each series of vessels through thermal testing at various trim differences;
- energy consumption control and optimization for heating and ventilation of living quarters on the ship;
- optimization of load power in navigating and parking modes;
- maintaining a good practice of energy conservation on the ships;
- control over the state of the hull and its timely cleaning. This is exercised by monitoring load (screw) characteristics of the main engine according to the S3ES-Novoship programme. The speed of the vessel with respect to the ground and water, weather conditions and the screw slip are controlled on a daily basis. In some cases, underwater filming is carried out, allowing for an estimation of hull fouling;
- strict maintenance of the main engine cylinder lubrication at the level no higher than recommended. The company follows recommendations of the main engine manufacturer and the Flame Diagnostic company which oversees the cylinder oil consumption and provides recommendations for optimizing the oil feed according to the analysis of samples of waste cylinder oil;
- determining readiness of the ship’s power plant depending on the harbour accommodation and requiring a minimum number of mechanisms working (instant readiness and readiness in a given time);
- usage of innovative low-friction coatings for painting the hull in order to increase the interdocking period, as well as reduction of the underwater hull fouling and exemption of cleanings in the interdocking period;
- scheduled replacement of incandescent light bulbs with energy-saving (fluorescent, including compact fluorescent, LED) bulbs. Optimal placement of light sources (local lighting, accent lighting). Increasing the light output of existing sources. Usage of lighting control devices (motion sensors, light sensors, timers);
The S3ES-Novoship programme has been implemented on SCF Group ships since 2006 for the collection and processing of information on the use of fuels and oils.
- More about the S3ES-Novoship programme
The S3ES-Novoship programme makes possible:
- controlling all important parameters of the vessel (fuel and oil, main engine output and speed of rotation, travelled distance and vessel speed, etc.);
- carrying out daily analysis of fuel and oils consumption in order to give its graphical representation;
- controlling the characteristics of each of the ship's fuel consumers for a long period of time in order to identify possible causes of high consumption;
- assessing the effectiveness of organizational and technical measures aimed at optimizing fuel and oils consumption;
- identifying inefficient modes of the main engine’S operation in terms of fuel consumption and developing methods to improve its efficiency and energy security;
- producing automatic calculation and evaluation of the operational energy efficiency ratio (EEOI) for the flight or any period of time to assess the CO2 emissions (in accordance with the IMO MEPC.1 / Circ 684). It is introduced in order to estimate greenhouse gas emissions and assess the energy efficiency of existing ships.
The programme can be adapted to different tasks for optimisation of fuel and oil consumption on vessels.
Energy audits are conducted on the company’s ships. These monitoring activities consist of collecting and processing information on the use of energy resources, obtaining reliable information about fuel consumption and performance of oils and energy efficiency of the main engines, auxiliary boilers and diesel generators, and identifying opportunities for energy saving and energy and environmental efficiency of ship power plants.
Ensuring the rational use of energy resources through the implementation of energy saving measures on vessels allowed us to reduce fuel consumption during voyages. While in 2011 fuel consumption for a mile travelled was 110 kg, in 2012 it was 109 kg, and in 2013 only 106 kg. Consumption was therefore reduced by 2.7%.
Fuel and oils usage efficiency on the company's ships after the implementation of the abovementioned activities has improved: the rate of cylinder oil consumption in the fleet has declined from 1.09 g / kWh in 2011 to 1.05 g / kWh in 2012, or by 3.8%. In 2013, oil consumption was reduced by 2.9%, from 1.05 g / kWh to 1.02 g / kWh.
