Choose DNV because… we have the expertise and understand tanker operations in cold climates DNV has included ice strengthening requirements in its class Rules for more than 125 years and today almost 400 of the DNV-classed tankers are ice strengthened. Our current Rules are based on Norway’s long cold climate shipping history, extensive operational experience from modern shipping in cold climate areas and significant R&D activities during the past few decades. Since ship operations in cold climates require much more than just ice strengthening of a ship’s structure and propeller, we have developed technical standards that are relevant for safety and reliability under cold climate operations. The degree of necessary winterization may vary from just control of icing in open waters to ice-breaking abilities in temperatures of -40oC and below. For this reason, class notations applicable for different cold climate conditions have been developed, covering the entire range of alternatives.

DAT (-xx) – Standard for low temperature materials DEICE – Standard for icing control OPP-F – Oil Pollution Prevention for Fuel oil thanks CLEAN – Controlling and limiting operational emissions and discharges

DNV has incorporated the Finnish and Swedish Maritime Authorities’ (FMA) Rules in its Baltic Rules.

“In all vessels that may have to steam through ice, the frames at the extreme forepart are to be closer than here directed, or some other sufficient additional strengthening of the vessel’s forepart must be adopted.” Abstract from DNV’s Rules and Regulations, November 1881

RPS – Fully Redundant Propulsion WINTERIZED BASIC – Standard for operation in open water with small quantity of ice WINTERIZED – For operation in medium cold climate conditions with ice

WINTERIZED ARCTIC – Operating in extreme cold climate/ice conditions COMF-V – Comfort Class for noise and vibrations COMF-C – Comfort Class for indoor climate

Choose DNV because … we put knowledge into tools Software for designers, yards and manufacturers

DNV was one of the first class societies to develop advanced software for directly calculating a ship’s structural strength. We are also still in the lead with a variety of tools supporting rule checks and the advanced analysis of ship structures. Nauticus Early Design (NED) is a 3D information system for ship building. It is a combined CAD and Analysis system that focuses on the early stages of design and enables ship designers to perform Contract design and Classification design faster and better, based on a common product model. The most powerful 3D modelling and drawing generation functions are integrated with Nauticus Hull’s well recognized analysis capabilities for Class rule checks and finite element analysis. Nauticus Early Design is based on an open architecture and integrates well with systems for Hull fairing and various Naval architect calculations. Unique support for CSR

The new rule requirements for Oil tankers introduce a radical shift towards more com-

puterisation of the rule formulations and structural assessment. Hence, good software support is critical in order for any Class to provide timely and rational support to shipowners as well as to designers and shipbuilders. In response to this, DNV’s well established Nauticus Hull® program has undergone a major upgrade to provide efficient support for the new Rules. Software for owners

An increased demand for tonnage, combined with a more distributed design and production process and a scarcity of experienced people, has made special demands on shipbuilders. DNV has developed Nauticus Construction to help follow up and document newbuilding and conversion projects from design to delivery. Nauticus Construction has become extremely popular with its users throughout its five years of development. Head office newbuilding departments can follow the progress of their projects in real-time, with immediate access to all documents and photographs stored by their site teams. No software installation, minimal training needs and knowledge sharing are the key concepts behind Nauticus Construction.

Structural Fatigue for Oil Tankers

Typical notations for Structural Fatigue for Oil Tankers:

CSR – Common Structural Rules PLUS – Extended fatigue life CSA-2 – Computational Ship Analysis CSA-FLS – Computational Ship Analysis Fatique Limit State


9

Choose DNV because… we know the structural fatigue challenges facing oil tankers I

Vetting schemes are increasingly focusing on the design’s fatigue standard and history of in-service cracking and repairs.

I

Cracks may result in oil leaking into the double hull and, in the worst case, in oil pollution with all the inconvenience and expense associated with this.

Material technology and fatigue analysis have for many years been among DNV’s specialities, not least boosted by the oil and shipping activities in the North Sea, which started more than 40 years ago. This area may be considered the world’s ultimate full-scale testing laboratory, and about 80% of all shuttle tankers operating in this area are classed by DNV. DNV has improved the additional class notations relating to the fatigue evaluation of tankers to offer yards and owners what is needed for their specific trade, beyond the basic scope of class.

The PLUS notation is intended for vessels operating in harsh areas and includes an extended scope of fatigue strength verification for hull structural details. The PLUS notation is based on the CSR notation with a minimum design fatigue life of 25 years of North Atlantic operation and with an extended scope of details to be verified. A new calculation procedure that covers all critical details in the transverse web frames using detailed FE analyses has been developed. A new class notation CSA-FLS has been introduced for the direct calculation of the fatigue life and is equivalent to the fatigue requirements of the CSA-2 notation.

Choose DNV because … we help you to stay in control and create a business advantage The shipping industry in general, and the tanker segment in particular, are experiencing an increased focus on hull integrity – for reasons of safety and cost efficiency. Competition is tough, and added requirements for CAP and TMSA compliance are important in order to be preferred by the oil majors. Transparent and continuous control of a ship’s hull condition may therefore create business advantages for ship operators and owners. DNV’s Hull Integrity Management (HIM) is a practical concept that has been developed for this purpose over a period of six years and has a proven track record.

For the technical staff

Be in control of the ship’s condition with Hull Integrity Management; don’t leave things to chance. Charterers recognize better maintained vessels, overall maintenance costs drop, the accident risk is reduced and compliance with regulations and standards is easier to achieve. DNV’s unique hull expertise and procedures for planning and following up inspections are combined with new easy-to-use Nauticus tools. This demonstrates the proven innovation of DNV’s Hull Integrity Management!

All the services are based on DNV’s extensive hull expertise, and apply to both DNV-classed vessels and vessels classed by other societies. The new, easy-to-use software incorporates DNV’s unique 3D technology. For ship officers and on-board crew

Based on DNV’s knowledge and hull expertise, Hull Integrity Management empowers the ship’s crew. It teaches them where to look and what to look for during regular on-board inspections. Hull Integrity Management helps to detect defects at an early stage and to deal with problems while they are slight.

Choose DNV because ... we care about the environment DNV’s purpose is “To Safeguard Life, Property and the Environment”. As a leading international ship classification society, we provide several services to the shipping industry. In a global context, transport accounts for 14% of the carbon dioxide emissions, and 2% comes from the shipping industry. The trend we observe is that emissions will have to be reduced, that regulators will require a further reduction of CO2 emission levels and that new technical solutions will be introduced. Some of the challenges we are facing are: I

Shipping’s share of emissions of NOx and SOx as well as Particle Matters (PM) is far higher as concerns local air pollution.

I

Serious exposure and impacts on human health are not accepted by society at large.

I

Antifouling and ballast waters affect the marine fauna.

energy used, the larger the potential for earnings and profits. Energy is about consumption and saving. It is about using energy sources to generate enough power to enable propulsion, heating, cooling, auxiliaries, etc. The maritime industry will be subject to stricter requirements concerning emissions to air in the future. The commercial conditions and operational framework will change. Alternatives to fossil fuel will no doubt be required. DNV is actively engaged in protecting the marine environment in all areas, ensuring that your vessel will meet tomorrow’s expectations and requirements. A newbuilding today is expected to trade for the next 30+ years. Is your ship prepared to face the future environmental challenges and requirements?

Choose DNV because… We provide support from “the cradle to the grave” DNV has a long history as a technology leader and industry support provider. Our extensive range of strong in-house resources, including state of-the-art laboratories, has enabled us to be at the forefront of technology development and new designs. DNV’s Customer Service Management (CSM) concept makes it easy for our clients to have access to DNV and our world wide resources. Survey planning is one example of where our Customer Service Managers can support our clients to identify the most suitable timing for a survey, and plan the practicalities involved.

Tankers may comply perfectly well with all applicable rules and regulations and still not meet the owners’ and charterers’ expectations. Hence, by harvesting from our huge knowledge base, DNV can offer services to owners, yards and designers during the early design phase too, with the purpose of avoiding surprises later on in the project. Areas of interest include cargo flexibility, corrosion protection, fatigue standards and suitable ice class arrangements for ship operations in cold climates - just to mention a few.

Optimum timing and good planning of surveys are key elements to minimize expenses and ensure a high quality of surveys. Our CSM concept has effectively contributed to DNV over the years consistently holding the record in Port State Control regimes worldwide as the top performer among class societies when it comes to port state detentions.
