With the current tanker market set to remain flat throughout 2019, shipowners and operators need to think laterally to stay ahead of the game. Unfavourable freight rates, tonnage oversupply and increased operating expenses are encouraging carriers to build efficiencies into every aspect of their operations. Recognising that fouling and mechanical damage to the hull can increase the engine power that a vessel requires by up to 20%, a key consideration in enhancing efficiency savings should be the application of the optimum protective hull coating.
There is no one solution to increase operational efficiency but to remain competitive it is important to understand the performance of the ship’s hull. Hard data and analysis plays an important role here. This is why Hempel, the worldwide coatings manufacturer, launched SHAPE (Systems for Hull and Propeller Efficiency) last year – a hull performance system founded on the ISO 19030 framework.
SHAPE combines elements of hull and propeller efficiency optimisation to maximise the quality of performance data analysis. This allows Hempel to deliver expert advice and solutions to every ship, enabling all ship operators to maximise their ship’s hull efficiency and their return on investment.
The future is bright – the future is data
Hempel’s SHAPE process can monitor the long-term trends via inservice key performance indicators. Six key stages comprise the SHAPE measuring and monitoring system. First, the vessel’s individual speed power reference curves are established. This is followed by collecting inservice data which is then cleansed and purified to eliminate extreme operating conditions and the effects of environmental factors.
Next, a precise speed loss calculation is performed. This is a critical measure for understanding vessel performance and fuel efficiency as power increase and speed loss are directly related. From this, the four KPIs are calculated:
Following this indepth analysis, Hempel is able to offer solid, valuable technical advice to the ship operator, advising them on the operational decisions they can take to positively impact their fuel efficiency and ensure best practice in vessel maintenance. This allows shipowners and operators to make data-driven decisions to operate more efficiently and competitively irrespective of vessel type, age and size to maximise their vessel’s profitability regardless of its operating patterns.
