Verification Software News

Finnish engineering company, Norsepower today announced that it has received €3 million in investment from a syndicate led by venture capital fund Power Fund III and has installed a second rotor sail on Bore’s Ro-Ro vessel MS Estraden. Data analysis and verification by NAPA, the leading maritime data analysis, software and services provider, has been fundamental to these developments by proving the effectiveness of Norsepower’s technology. A single Norsepower Rotor Sail was installed on the 9,700 DWT Ro-Ro carrier in early 2015. Although the weather conditions were largely calm over the three-month trial, data analysis from vessel performance monitoring and verification software, ClassNK-NAPA GREEN, demonstrated that the rotor sail delivered clear and significant savings of 2.5%.

Norsepower Oy Ltd. and Bore Ltd today carried out successful sea trial of Norsepower’s Rotor Sail Solution, a new wind propulsion technology for ships. The sea trials, verified by NAPA and supported by VTT Technical Research Centre of Finland, confirm fuel savings of 2.6% using a single small Rotor Sail on a route in the North Sea. With these fuel savings, the technology has a payback period of 4 years. Based on the trials, Norsepower and Bore believe that a full system on Estraden with two rotors has the potential to deliver 5% efficiency savings on an ongoing basis. Norsepower forecasts savings of 20% for vessels with multiple, large rotors traveling in favourable wind routes. The Norsepower Rotor Sail Solution was installed on the 9,700 DWT Ro-Ro carrier MS Estraden.

Herbert-ABS says use of an approved damage stability computer program is the “only logical option” to meet new International Maritime Organization (IMO) Damage Stability Regulations requirements for onboard damage stability verification. Herbert-ABS Software Solutions LLC has published an assessment of the impact of new damage stability regulations on tanker and gas carrier operations. Hendrik Bruhns, Herbert-ABS Software Solutions President, argues that employing an approved damage stability verification software is the most practical and cost-effective means of demonstrating compliance with the regulations. The IMO recently adopted guidelines for demonstrating compliance with the requirements for damage stability reporting in April and May 2014 during MEPC 66 and MSC 93.

ClassNK has released its new PrimeShip-GREEN/MinPower software, developed to help shipyards comply with the EEDI requirements of the Amendment to MARPOL Annex VI by calculating minimum propulsion power requirements in compliance with ‘IMO 2013 Interim Guidelines for Determining Minimum Propulsion Power to Maintain the Manoeuvrability of Ships In Adverse Conditions’. To evaluate minimum propulsion power requirement, added resistance in irregular waves should be calculated based on ship’s Lines, and this calculation can be difficult especially at the initial design stage. Consequently ClassNK has  developed this simplified formula to calculate added resistance in waves using only basic information such as main ship specifications…
