DNV GL been one of th eleading class societies, offers a specification review for any owne who is interested to build a vessel. Our strong competence on tankers and containers makes us a unique partner, who can enhance the knowledge of the owners intrested to built such ships.
2. 02 MARITIME Oil & chemical tankers
The competence and knowledge required to review
technical specifications is based on experience. DNV GL
has long experience in reviewing specifications; with
our deep knowledge of both the operation and the
building of all kinds of ships, we are ideal for assisting
the owners. Further, as the vessel is intended to operate
over a long time span, verification of existing and future
rules and regulations has to be taken into account.

OVERVIEW
Target clients
Shipowners in the design, pre-contract or contracting
phase for newbuildings.
Ship types
■■ Oil tankers (crude, oil products, asphalt, shuttle etc.)
■■ Chemical tankers
■■ Oil and chemical tankers
■■ Combination carriers carrying oil or chemicals
Purpose
■■ To review owners’ outline specifications.
■■ To review outline specifications or detailed techni-
cal specifications from shipyards or designers.
SCOPE
The scope of the service is to give an overall assess-
ment of the specifications with respect to:
■■ Class and statutory requirements in force
■■ Future known statutory, regional and IACS require-
ments
■■ Potential cargoes
■■ Relevant regional requirements (EU and USCG)
■■ Oil major requirements (OCIMF and ExxonMobil)
■■ Feasibility of design and specifications based on
experience from previous newbuilding project
execution and in-service experience
■■ New technology such as alternative fuels
■■ Equivalent level of safety for novel designs.
Class and statutory requirements in force
DNV GL rules, SOLAS, MARPOL, IBC code.
Future known statutory, regional and IACS
requirements
Requirements with known entry into force date or
requirements under consideration. Examples are
MARPOL Annex VI tier III NOx requirements, SOLAS
and IBC code amendments related to inert gas for
new tankers of 8000 dwt and above, and IACS har-
monized CSR.
Potential cargoes
Assessment of and recommendations related to ship
arrangements and specified equipment with respect
to chemical tanker cargo flexibility, for example
related to carriage of FAME and enhancing cargo
flexibility.
Relevant regional requirements (EU and USCG)
Assessment with respect to main regional require-
ments such as USCG VGP, VECS and ballast water
treatment issues, as well as future EU SOx and poten-
tial NOx requirements.
Oil major requirements (OCIMF & ExxonMobil)
Assessment with respect to main OCIMF SIRE VIQ
and ExxonMobil requirements and experienced
practices.
Feasibility of design and specifications based on
experience from previous newbuilding project
execution and in-service experience
Examples: comparison of capacities versus other
designs, recommendations related to cargo handling
efficiency (such as tank cleaning), cargo handling sys-
tem design, material selection, MGO operation etc.
