DRILLING UNITHUISMAN PRODUCT BROCHURE

DRILLINGGENERAL INTRODUCTION

Huisman offers complete drilling packages and is dedicated

to explore and realise new solutions to improve drilling op-

erations. Our projects are typically complex and innovative,

requiring solution-aimed thinking, technical excellence and

partnerships with our clients. This has already resulted in a

number of new value-adding solutions and orders for innova-

tive and technically challenging drilling equipment sets.

Huisman has in-house capabilities for vessel design. This

allows us to provide solutions in which vessel and equip-

ment are fully integrated, leading to radically different designs

for drilling units. The first drill ships based on these ideas

are currently under construction, representing a major step

change in the industry.

The unique combination of our in-house design and engi-

neering expertise, production facilities, testing capacity and

installation location enables us to deliver custom-made, state

of the art equipment on a turnkey basis: in time with fully

operational equipment from day one. All Huisman products

are designed and built in accordance with the international

standards and certified by recognised authorities such as

ABS, API and DNV.

DRILLINGGENERAL INTRODUCTION

The innovative Orion is a self-propelled semi-submersible

drilling unit. Depending on the design it can work in mid water

or ultra-deep water and in moderate or harsh environment.

All models can be outfitted with a mooring system and/or

thrusters and have a drill floor, construction floor and drilling

tower.

The unit with its integrated drilling equipment will be suitable for:

• Exploration and Production drilling operations

• Completions

• Coiled tubing and wire line operations

• Well intervention

• Installation of X-mas trees

• Well testing

The design of the unit focuses on Efficiency, Health, Safety

and Environment. The unit features a flat main deck, a drill

floor flush with the main deck and a dual Multi Purpose Tower

allowing offline activities. Safe and simple material handling

is achieved by the flush main deck/drill floor, a cargo elevator

and a forklift corridor in the deck box.

The design of the drilling package focuses on drilling

efficiency and versatility. The drilling package is suited

to accommodate the latest drilling technologies, such as

automated tripping.

The Huisman Dual Multi Purpose Tower (DMPT) has no

V-door limitation. The handling procedure of the SSBOP and

X-mas trees is changed, resulting in the complete elimination

of an elevated drill floor. The CoG is lowered, which increases

the stability of the vessel. This results in a high payload /

displacement ratio.

INSTALLATION AND COMMISSIONING

Since the DMPT is a single integrated unit that houses all

equipment, the interface with the vessel is greatly simplified.

In combination with the Huisman substructure, that comprises

the complete drill floor, control cabin, drilling VFD’s and HPU,

the DMPT can be fully tested and commissioned on our

quayside. After the testing and commissioning phase the

DMPT can be installed with one single lift onto the vessel,

significantly reducing the time the vessel has to stay at the

quayside.

This integrated approach allows both Huisman and the

shipyard to build the equipment and vessel simultaneously.

It also reduces the number and complexity of the interfaces

between the vessel and the equipment, which reduces the

time for installation and commissioning.

MAIN ADVANTAGES

The DMPT has no V-door limitations and a hoistable floor.

Therefore it is possible to skid the BOP (or X-mas tree)

underneath the floor when it is hoisted and then lowered on

the construction side. The BOP is then skidded from the aft

to the forward well center by means of a skid cart that moves

along the moon pool under the substructure. This handling

eliminates the need for a high substructure. The drill floor

is flush with main deck allowing safer operations and lower

accelerations on the drill floor.

The Orion class semi-submersible offers a much larger

payload than the competition but with a smaller displacement.

The Orion has a flat deck of more than 6500m2 with a gantry

crane covering the aft deck.

DUAL MULTI PURPOSE TOWER

The vessels distinctive feature is the Dual Multi Purpose Tower

(DMPT). It has a welded box girder type load bearing structure

with a hoist on either side. One hoist is situated above the

well centre in the drill floor on the port side of the tower and

the other above the center in the construction floor on the

starboard side. There is no lattice type derrick structure

around the hoists, thus there is no V-door limitation, large

objects can be skidded or hoisted with the cranes directly to

the well centres or in the moon pool area.

The construction side is utilized for BOP and running of risers.

This can be done during drilling of the surface hole. Also

the handling of large subsea structures (X-mas trees) and

stand building is performed on the construction side. The

construction floor can be hoisted by the construction hoist

in order to skid the SSBOP or X-mas tree underneath. The

structures can be lowered into the water and the floor can be

lowered to its’ original elevation. This eliminates the need for a

large substructure height.

The DMPT also has some built-in redundancy, namely the

dual drum drawworks and the pipe handling system. Should

one of the winches fail the other can still operate the traveling

block at full load, however at half of the original speed.

Both well centres can operate from the two setback drums.

Therefore the system is still fully operational should one

pipe racker fail. Also the setback drums are outfitted with

redundant drives.
