Ulmatec has delivered two Moon

Pool LARS™ (pictured), a hydraulic

hatch system for the main moon pool

and skid systems for the work deck on

Island Enforcer, an advanced subsea

construction vessel.

ULMATEC MOON POOL LARS™

The Ulmatec Moon Pool LARS™ for safe handling, storing,

launching and recovery through the moon pool. This vertically

guided system is fitted to the moon pool wall. With its

operational area placed inside the vessel and screened from

wind and weather, it is designed to provide a safe platform for

both operators and ROV equipment.

CURSOR SYSTEM FOR CONTROLLED RELEASE AND SOFT LANDING

When the ROV/TMS is to be retrieved to the vessel,

it is first raised with the umbilical winch to about 50

metres beneath the keel. The umbilical winch will then

cease lifting and the lower cursor will be lowered to

about 30 metres beneath the keel.

In recovery mode, the umbilical winch will lift

about 20 per cent faster than the cursor winch. This

reduces the jolt when the lower cursor engages with

the ROV/TMS.

When the lower cursor and the ROV/TMS have

latched together, the signal will be given for the

umbilical to change to constant tension (CT) mode,

and cursor winches will guide the lower cursor and

the ROV/TMS into the upper cursor, up into the moon

pool and over the hatches to the deck.

A cursor guides the ROV and its tether management

system (TMS) through the moon pool.

When the ROV/TMS reach the bottom of the moon

pool, the main (upper) cursor halts and the ROV/TMS

is lowered to the desired depth.

The lower cursor is conically shaped in order to

guide the umbilical during the operation.

ULMATEC U-FRAME LARS™

The Ulmatec U-Frame LARS™

is a deck-mounted system for safe

handling, storing, launching and

recovery over the side. With its long

reach of 4.5 metres from the vessel side

and 3.5 metres below deck level, it can

be installed on a mezzanine deck, for

instance.

A FLEXIBLE SOLUTION WITH A LONG REACH AND HIGH CAPACITY

The Ulmatec U-Frame LARS™ is a mobile system

which ensures rapid and simple mobilisation and

demobilisation.

As a deck-mounted system, it can easily be adapted

to existing vessels.

Safe working load 15 000kg

The Ulmatec U-Frame LARS™ has properties which

minimise the risk of damaging equipment during

launch and recovery.

In working position, the distance from the ship side

to the umbilical cable is about 4.5 metres.

In addition, the frame extends no less than 3.5

metres down towards the splash zone from the deck

where it has been installed.

Its extended dip features mean that the system

provides flexible positioning. It can be located on a

mezzanine deck, for instance.

ULMATEC OVERHEAD LARS 4.5™

ROVVOR

The Ulmatec LARS 4.5™ is designed to operate at

about 5 metres from the vessel side to the centre of

the umbilical at deck level when in launch and recovery

position. That provides greater distance from the ship

than a standard A-frame, and a considerably lower gap

between the launch/recovery position and the splash

zone. This permits soft handling in rough weather as

well as optimised ROV lowering and raising.

When deploying the ROV, the vertical crib can be

hoisted above the lower part of the hangar side hatch

for more secure operation in heavy seas.

A solid weather-tight hatch measuring three metres

from deck and into the hangar opening can be supplied.

This protects crew and equipment in the hangar

from waves and weather along the vessel side during

operation.

The ROV operators have optimum working

conditions, with a clean ROV deck providing easy access

during service and maintenance.

The system is equipped with a trolley for parking

and separating the ROV and TMS, which simplifies

service and maintenance.

ULMATEC HEAVY-DUTY LARS 6.0™

A guidance system which follows the ROV down

the vessel side is important during launch and recovery

operations on ships where the ROV hangar is a long

distance from the splash zone.

The guidance system eliminates swinging of the

ROV, even with large vessel motion. This eliminates the

danger of the ROV coming into contact with the vessel

side on its way up or down.

The Ulmatec LARS 6.0™ comprises two trolleys –

one horizontal, running on horizontal guide beams

fitted to the hangar ceiling, and the other vertical,

running on vertical guide beams fitted to the horizontal

trolley and the ship’s side.

The system can also be delivered with a guidance

system beneath the sea surface. The vertical guide

beams on the vessel’s side will then end at the bilge

radius below the waterline.
