INTERVIEW: Paal Johansen, DNV GL - Maritime
In the Q1 edition of Maritime Professional ( we published a “Class Roundtable” with various head of class. Room did not permit for full answers from every participant, so please find here the complete interview with Paal Johansen, Head of the Americas Region for DNV GL – Maritime.

Though a major change may be expected as a result of the DNV and GL merger, as far as the Indian shipping industry is concerned there will hardly be any effect

SHIPPINGInsight 2012 will bring together stakeholders from across the industry to explore best practices in ship efficiency. Panels will focus on major issues, including ship design and construction, fuel and propulsion alternatives, hull performance, asset management strategies, voyage optimization and regulatory compliance.

Pollution exists in many forms and while cleaning up the air we breathe, is receiving the most attention from legislative bodies, the Marine Environmental Protection Committee (MEPC) of the IMO recently asked maritime nations to review their commercial fleets to identify the ships that contribute most to underwater noise pollution. DNV is showing leadership in creating a low noise notation for ships, “DNV Silent”. There are numerous civilian applications where low noise emission is desirable, such as research ships, fishing vessels and offshore support vessels. Main noise sources are propellers, diesel engines, gearboxes, generators, thrusters and water flow over the hull and making things worse, the ship’s hull acts as a sound box. Thinking about these issues early on in the ship specification allow many of these noise producing sources to be attenuated

Many propulsion aspects were not covered in our previous Quantum report, therefore we call this one Quantum 2. Container ship designs go for maximum hull speed requiring highest practicable engine power. The slump of the last two years has meant that ships often steam well below their designed maximum speed. Many propulsion arrangements were investigated for the Quantum, however a diesel electric solution was most favored using a twin propeller arrangement for full redundancy. It was decided the best option was two steerable Azipods. Adding further flexibility, all the gen set engines are dual MDO/LNG fuel and the two on board LNG tanks allow engine operation in emission sensitive areas.

In the April DNV Container Ship Update publication, the new Quantum container ship survey and design brings many subjects together in one report. Although a concept ship, it is a practical design that could be ordered today but equally well, be ordered, unchanged five or ten years hence. The survey of ship owners gives a wonderful “insight” into the minds of the prospect ship owners. As a container ship of the future, it strives to achieve the aim of transporting more cargo with less fuel for a low impact on the environment. The ship specification is 6,200 TEU capacity and operating speed of 21 kts. As the ship’s life may well be 25-30 years, foresight into meeting the changes in legislation, especially emissions and technology is required. Of all the parameters to be considered in designing a new ship, clearly it is the engines, propulsion and auxiliary, that are the foremost concerns for ship owners and in order of importance are efficiency, reliability and emission compliance.
