General

The CLV Siem Aimery is an advanced Cable Installation, Repair

and Maintenance Vessel. The vessel is designed to satisfy cable lay

demands of the offshore wind and offshore oil and gas industries,

whereby the vessel is specially designed and equipped for submarine

cable laying operations with specific focus on good sea-keeping

capabilities, excellent station keeping performances and low fuel

consumption. The key design criteria include the ability to operate

in harsh sea conditions in combination with the ability to launch and

recover her two work-class ROV’s and her trenching ROV.

These abilities increase the operational availability of the vessel and

extends the operational working period per year. The cable laying deck

is installed above the main-deck in a climate controlled environment,

and includes a cable quadrant and track deployment system capable

of handling cable protection systems. This design decreases risk to

the cable laying crew and the cable, specifically in adverse weather

and adds to the vessel’s ability to continue cable lay operations in

extreme conditions.

Description

The vessel is designed for international trade as described by the

Classification Society DNV-GL and is fitted with:

· Two cable carousels/turntables

· A sheltered cable laying deck including tracks & workshops

· Cable handling equipment including linear cable engines

· Two work-class ROV including launch and recovery system

(LARS) located aft and amidships

· One trenching ROV in hangar with LARS and gate to launch on

starboard side

· A high standard, low noise level accommodation

· A 360 degree panoramic bridge

Propulsion is provided by two azimuth propellers aft, two tunnel

thrusters and one retractable azimuth thruster forward. The vessel

is designed for continuous operation on ‘Dynamic Positioning’ (DP)

which can be up to maximum thruster power. Particularly notable

is the vessel’s compliance with the comfort class notation and the

requirement for low noise and vibration levels in the accommodation

spaces under DP operating conditions as this is the normal mode of

operation of the vessel. Two passive stabilizing tanks are built below

main deck and in the superstructure.

Cable Lay Equipment

The vessel is specifically engineered to offer a high cable

carrying capacity without sacrificing workability offshore.

Additionally, by handling the cable via quadrant and track

system in an environmentally protected working hangar, the risk

of damage to the cable is reduced and offshore workability

is increased.

One electric carousel, 2,500 t loading capacity, ID 4 m/OD 18 m/height 4 m

One electric carousel, 1,750 t loading capacity, ID 4 m/OD 16 m/height 4 m

Four electric linear cable engines, WLL 8 t, suitable for Master-Slave mode

Two electric feeder cable engines, WLL 2 t

Two electric A&R winches, WLL 20 t

Two electric tugger winches, WLL 5 t
