dnv gl – your

trusted partner

Today’s tanker operators prioritise safety, quality and

avoiding accidents. Cargo owners also want to be

sure that no shortcuts are taken that might threaten

these fundamental goals. These priorities are sup-

ported by DNV GL’s stated mission: safeguarding life,

property and the environment. Quality is the number

one priority in DNV GL and this is one of the reasons

why we are a trusted partner for tanker operators

when it comes to safety and compliance.

We offer classiication and related services, support-

ing tanker owners in their critical efforts to perform

in compliance with their charterers’ expectations and

requirements. Our goal is to stay in the forefront of

technology developments and innovation, respond-

ing to commercial market developments and de-

mand for environmental and safety improvements.

DNV GL has not only signiicantly expanded its

global network through the merger of DNV and

Germanischer Lloyd, it now has more R&D resources

and expertise to strengthen its technology and com-

petence base. And with around 6,000 highly skilled

employees active in the maritime segment, DNV GL

is in a unique position to support customers with

premium, cost-effective classiication and advisory

services – anytime, anywhere.

For our customers, that means we have more survey-

ors, faster response times and more experts within

business-critical disciplines than any other classii-

cation society.

Our expertise in the tanker segment cannot be

measured simply by the number of ports where we

operate or the number of vessels in our portfolio.

Rather, our success is determined by the quality of

the services we deliver to each individual customer.

We believe that while the size of our organisation

represents a genuine beneit to our customers, our

skill, dedication and understanding of the tanker

business are what differentiate DNV GL from compet-

ing providers of class services.

Today, DNV GL is a technology leader in the tanker

segment. By developing rules and maintaining

cutting-edge competence, we remain committed to

strengthening our peerless reputation in this dyna-

mic segment. Looking ahead, DNV GL will continue

to focus on ship safety, eficiency and environmental

performance to help make your operations safer,

smarter and greener.

DESIGN AND

PLAN APPROVAL

The future will bring some signiicant changes to the

shipping industry. With a continued focus on energy

eficiency and stricter requirements to air and water

emissions, the industry is likely to adopt new tech-

nologies that will affect the design, construction and

operation of next generation tankers.

New operating proiles have led to modiied hull

forms and new engine types for variable speeds.

Over the past ive years, regulatory compliance has

become more complex, with divergent requirements

from lag states in addition to speciic requirements

from various cargo owners.

DNV GL is looking to the future by developing con-

cept studies of new designs and technologies, such

as Triality, a tanker concept that demonstrates how

new technologies can be used to design, construct

and operate tankers more eficiently. But we also

work closely with customers to optimise new de-

signs, using state-of-the-art technology to calculate

energy eficiency and improve performance.

DNV GL has vast experience from a large number

of newbuilding projects. We are committed to share

our unique competence within the tanker segment

with our customers in the critical early phase of new-

building projects in order to help develop a specii-

cation tailored to your needs.

One example is fuel strategy support, where we

assist with input on cost-beneit analysis, regulatory

evaluations and rule requirements, including a safety

assessment to prepare your ship for LNG, an LNG

retroit or a scrubber installation.

Setting the standard in tanker design

DNV GL has been at the forefront in the develop-

ment of state-of-the-art computational technology

for direct analysis of tanker loads and responses. The

new IACS Harmonised Common Structural Rules will

set a new standard for tanker design. DNV GL has

been involved in the development of the new rule

set and is currently helping yards and owners to get

ready for the new requirements. DNV GL also offers

unique class notations documenting compliance

with performance and environmental criteria in the

tanker industry.

DNV GL has played a key role in working with the oil

industry to develop the shuttle tanker standards to

meet the most advanced challenges for safely per-

forming cargo loading in the harsh offshore environ-

ment. Tailor-made class notations for shuttle tankers

have been developed to ensure that the necessary

safety standards are maintained – notations that are

recognised by major oil companies as the accepted

standard. Some relevant class notations for tankers

are described below.

Plan approval

DNV GL’s maritime knowledge hub for tankers is in

Oslo, where we have a competence centre staffed

by leading technical experts in the tanker segment.

The organisation also has plan approval ofices in

Hamburg, China and Korea, providing customers

with “one stop shop” services covering all relevant

disciplines. Strong, long-term relationships with the

industry’s leading shipyards put DNV GL in a unique

position to support customers during the design and

plan approval process.

Design support

DNV GL offers value-added advisory services in vari-

ous disciplines and competence areas to support

owners, shipyards and designers during the design

process.

operation

Your global resource for ships in operation

Quality and safety at minimum cost are key success

criteria in the tanker segment. The combination of

oversupply, depressed rates and high fuel costs has

had a signiicant impact on the tanker segment, for-

cing owners to review how they operate their leets.

Shortcomings in quality and compliance will put

ships out of business and, if challenges do arise, it is

essential to resolve them as quickly as possible. DNV

GL is involved daily in answering customers’ techni-

cal questions and resolving port state control and

vetting issues to keep customers’ ships in business.

DNV GL has taken a leading position in working with

owners and operators to help manage these issues.

We offer comprehensive 24/7 back-ofice support

through the DATE (Direct Access to Technical

Experts) service, providing support to surveyors

and owners worldwide. One of the key services we

provide is handling questions and comments related

to vetting remarks for tankers.

DNV GL also offers an Emergency Response Service

(ERS) that provides prompt access to shore-based

expert assistance to assess the damage stability and

residual strength of a vessel in distress. ERS is a fast,

reliable, around-the-clock professional assessment

of the condition of a ship in an emergency situation.

DNV GL advisory and class services empower opera-

tors to improve eficiency and reduce costs, and we

have a streamlined process for transferring class. Our

local DNV GL ofice is always standing by to plan the

practical aspects of the class transfer with you in or-

der to ensure a smooth transition with the minimum

disruption to your operations.

reCyCling

The International Maritime Organization (IMO) has

developed a standard for ship recycling (the Hong

Kong Convention). While it may take time for the

Convention to enter into force, many prudent owners

are already taking steps to ensure that ship recycling

is done in a safe and environmentally friendly man-

ner in anticipation of ratiication by member states.

DNV GL offers a variety of class notations that help

ship owners specify certain minimum standards

related to the use and documentation of hazard-

ous substances on board throughout the entire life

cycle of a vessel. Many owners and yards are already

preparing to comply with the Inventory of Hazardous

Materials (IHM), a key provision of the Convention.

In support of these efforts, DNV GL has developed

the IHM Green Server, which is speciically designed

to help owners keep IHM documentation updated

throughout the vessel’s life cycle, thus providing

relevant information when the vessel is due to be

recycled.

DNV GL offers advisory services to help stakeholders

collect information, develop plans and documents

for recycling, and assess recycling facilities.

Solutions for a changing industry

Operating a successful leet of tankers in the future

will require the adoption of new technologies and

innovative solutions. Those players willing to invest

in new technologies are likely to achieve a strong

competitive advantage in the years ahead. Energy

eficiency, operational lexibility and not least the

best fuel strategy to meet future emission require-

ments are key areas which are highly relevant to the

tanker segment.

DNV GL allocates a signiicant part of its yearly reve-

nue to projects bringing innovation to the maritime

industry, as well as to projects that help maintain our

position as a leader in selected technology ields.

In addition to being in the forefront of rule develop-

ment, DNV GL is a recognised industry leader in

research and development, often working with other

stakeholders in Joint Industry Projects. With concept

studies like Triality and Best Plus, DNV GL has taken

the lead in developing new tanker concepts, em-

ploying both available and emerging technologies.

Another recent example on research and innovation

in DNV GL is the development of COSSMOS (Com-

plex Ship Systems Modelling & Simulation). COSS-

MOS is a software tool for optimising the design

and operation of energy-intensive systems such as

ship machinery power plants. The tool is especially

suitable for analysing the complex arrangements

of steam/boiler systems and waste heat recovery

systems providing good decision support during the

design phase.

DNV GL contributes expertise to the development of

emerging maritime technologies and works together

with other industries to develop solutions for tank-

ers. In addition, we offer acknowledged processes

for qualifying new technology and assist in bringing

safe, commercially viable and eficient solutions to

the market.
