UNDERSTANDING

Through our work with designers andshipyards worldwide and our own in-

house technical expertise, we know the

market, trends and latest solutions.

Self-elevating units’ specific designs

deserve a classification society with the

technical expertise to evaluate and

approve them. We understand these

specialities and our approval engineers

ensure that the most effective, efficientand flexible solutions are delivered.

DEDICATED RULES

– A COMPLETE AND

CLEAR OVERVIEW

To ensure the right interpretations and

requirements in compliance with mar-

ket standards and international regula-

tions, DNV has created a dedicated rule

book for self-elevating units. Based on

our renowned DNV Offshore Standards,

these rules provide clear guidance and

an overview of the relevant require-ments for all stakeholders (ref table 1).

The guidance can be recognised in

the rule book’s structure. From Part 1,

introducing classification and design

principles, to Part 7, listing the relevant

requirements and procedures for a unit

in operation, the book leads the reader

through the relevant aspects of class aligned with the asset’s building phase.

Parts 2 to 4 are the most relevant for

the design phase. They discuss the

requirements for the material, structure,

machinery and systems (ref figure 1).

ENHANCED SYSTEMS

Previous offshore incidents have made

the public increasingly aware of the

MOU segment, giving an incentive to

demonstrate a safety level beyond

compliance. DNV has always been at the forefront to improve safety and

reliability and wants to support owners

and yards that aspire to do so. Based

on this ambition, DNV has defined

a new voluntary notation called

Enhanced Systems (ES).

The ES notation is based on our accu-

mulated knowledge and experienceand includes optimal design solutions

that cost-effectively improve safety &

reliability. It provides a clear message to

owners and yards striving for beyond-

compliance safety levels. A valuable

message in today’s competitive market.

From a regulatory point of view, self-elevating units are traditionally covered by Mobile Offshore Unit

regulations and standards. On drilling location, however, they can be regarded as fixed installations. It isimportant that this dual nature is taken into consideration. If not, expensive requirements may be imposedwithout having any positive effect on safety.

By choosing DNV, you can rest assured

that these factors have been consid-

ered prior to your self-elevating unitentering operation. DNV’s yard experi-

ence is vast.

Our long-standing presence at yards

in Japan, Korea, China, Vietnam,

Singapore, India, the USA and the

Middle East means that our large,

well-qualified site teams contribute

their expertise and provide a problem-free new building process.

INTEGRATED SOFTWARE-

DEPENDENT SYSTEMS

Drilling-control systems on board

typically contain about 500,000 lines

of programming each. In comparison,

an Airbus A380 commercial airplane

has about one million lines of code.

In terms of software, offshore units

tend to be far more complex than

airplanes, yet the software on these

units is not nearly subject to the same

controls and testing as in the aviationindustry.

The system components on board

offshore units are manufactured by

different suppliers and integrated at

the yard. It is typically during this pro-

cess that compatibility issues which

compromise unit performance are

detected, delaying commissioningand operational availability.

To support yards and owners in con-

trolling the above integration risk,

DNV has developed Integrated

Software Dependent Systems (ISDS).

ISDS is based on proven methodology

to ensure software integrity from the

newbuilding process throughout the

unit’s lifetime. Through specific pro-

cess requirements, ISDS helps prevent

software issues that may result in costly

delays at the yard.

QUALITY SURVEY PLAN

The above service connected to the

(voluntary) class notation ISDS does

not imply a heavy burden and intrusive

involvement from classification. This is

a leading principle for our classifica-

tion services in general, and we have

taken this principle further in the

Quality Survey Plan (QSP).

This plan is the result of a pre-project

assessment and forms the basis for

DNV’s involvement during the remain-

ing building phases, including delivery.

This approach aligns the yard’s quality

control, owner representatives’ inspec-

tions and class surveys, thereby pre-

venting overlap while ensuring the

resulting unit meets all expectations,

regulations and standards.

Commissioning and on-time delivery have not become easier over the years. Tight deadlines and strict

contracts that impose penalties on both owner and yards are only one side of the coin. The furtherintegration of different systems and greater dependency on software make meeting deadlines an increasing challenge.

DEDICATED RULES GUIDING YOU

THROUGH

In this phase too, the dedicated rule

book OSS-104 will guide you through

the relevant requirements, ensuring

efficient and effective compliance with

the DNV class standard.

CLASS SERVICES DURING THECONSTRUCTION PHASE

DNV class services cover the following

areas:

Product and supplier

certification

DNV will certify products ordered by

the shipyard as per current require-

ments set out in DNV’s rules. Product

certificates issued by the DNV surveyor

at sub-contractors’ sites will be collected

and verified by DNV’s project manager

at the site. Welders and other special-

ists as well as suppliers will be certified

as per rule requirements.

Newbuilding supervision andverification of tests and trials

A dedicated project team consisting of

surveyors and plan approval specialists

will classify the vessel. The lead surveyor

at the shipyard will be the overall pro-

ject manager.

Well-qualified surveyors will conduct

the survey during construction. Inaddition, specialist surveyors will pro-

vide assistance whenever required.

Issuance of class and statutory

certificates

Upon the successful completion of all

inspections, tests and trials and once

all comments have been responded to,

DNV will issue class and statutory cer-

tificates for the newbuilding at delivery.

WORLDWIDE NETWORK

In a global offshore business environ-

ment, there is an increasing awareness

of risk. Our offshore centres in

Shanghai, Singapore, Dubai, Houston, Rio and Stavanger along with 300

offices in 100 countries enable us to

work closely with our customers and

share the best practices throughout

the world.

LOCAL AVAILABILITY

A worldwide network is nothing with-

out a portal. DNV provides you with

this portal and a dedicated rig coordi-

nator for each of your units. This coor-dinator is your contact person, leverag-

ing the entire DNV organisation for

your benefit.

DEDICATED SERVICE CENTRE

Over the years, DNV has gained valu-

able experience from interactions with

various rig owners and jacking system

manufacturers regarding issues with jacking systems, guides, legs, structural

failures, spudcans etc. Numerous

succes stories resulted and learning

elements have been brought to our

experience exchange gatherings.

“Time is money” is a well-known phrase; nowhere is this more applicable than to self-elevating unitsin operation. The availability of the platform and onboard systems make the unit a money-maker while

downtime is a money-breaker. DNV understands this world like no other class society, and our paramountinterest is to ensure your availability and keep your downtime to an absolute minimum.

We have decided to transfer this valu-

owners in the form of an in operation

service centre located in Dubai, UAE.

This not only reflects our commitment

to the market segment, but will also be

the focal point for all our jack-up

related knowledge and experience.

The Jack-up Service Centre will system-

atically collect the failure information,

analyse and investigate the causes and

deliver a state of the art solution. We

have dedicated people working in the

service centre to assist the owners.

DEDICATED RULES, ALIGNED

PROCEDURES

During the operational phase, our

dedicated Self-elevating unit rules

provide you with a clear overview of

the relevant requirements and proce-

dures to stay in compliance.

Our procedures are aimed at carrying

out the necessary inspections with aminimum of interference to your

operations. For example, the spudcan/

leg survey is separate from the bottom

survey. We can thus inspect both these

parts when suitable for your opera-

tional profile (i.e. the bottom when

on station, the spudcan/legs during

a transit) and be sure your asset is in

the right condition and in compliance

with international regulations.

HULL INTEGRITY MANAGEMENT

(HIM)

Continuous control of a self-elevating

unit’s hull condition creates business

advantages for rig owners and charter-

ers. Owners have an increased focus

on the condition of their assets; in

addition the authorities are paying

greater attention to hull integrity.

DNV’s Hull Integrity Management is

a practical concept that has a proven

track record.

Based on DNV’s knowledge and hull

expertise, HIM empowers your rig’s

crew. It teaches them where to look

and what to look for during regular

onboard inspections. Degraded hulls

have caused cost overruns in renewal

surveys. HIM helps detect defects earlyon and deal with problems while they

are still small. HIM is a tool that is

shared by the owner and DNV. The

early identification of degradation

findings (before they become class

critical) allows the condition to be

managed more pro-actively. An in-

service 3D model showing the data

available worldwide allows the opera-

tor, owner, class and subcontractors

to collaborate digitally. The HIM 3D

model provides the right information

when needed.

In typical offshore operations, there

are constant challenges to be met in

order for the project to be financially

successful. Overcoming these requires

the project’s key participants to have

access to the best assistance in all areas.

However, it is often difficult for these

players to find and access resources

that offer the necessary technical

expertise and are adequately firewalled

from the project in order to provide

truly independent assistance in assess-

ment and decision-making.

DNV is in the enviable position ofpossessing both the necessary technical

expertise in the offshore industry and

universally acknowledged independ-

ence and integrity. This enables us to

meet customer needs in a truly sup-

portive and unbiased way.

services is to concentrate on the capa-

bilities contained within the DNV

organisation and fit customised solu-

tions to the customer’s needs. DNV’s

capabilities cover the following areas:
