Answer

Jersey Harbours has placed an order for a Liebherr LHM 250 Harbour Mobile Crane, to replace the scotch derrick on the New North Quay. This derrick is in excess of 30 years old.

1. The crane has a safeworking load of 64tonnesinheavy lift mode and 44tonnes in normalmode.By comparison the existing scotch derrick has a safeworking load of35tonnes. Part of the design specification included provisionfor the cranetobe fitted with sufficient purchasecable to reach the lower hold of a ship at extreme low water.
2. The  New North Quay has been  surveyed prior to placing  the order for the  new  harbour mobile.  No strengthening or reinforcement is required for the existing structure. Theworkingareas of the crane pads will be marked out to coincide with thestrengtheningmembers that support the surface ofthequay.

( i)  No strengthening works will be required, although clearing the quay will afford the opportunity to repair

some working surfaces.

( ii ) The New North Quay may have to be closed briefly for the unloading of and erection of the new crane.

A maximum of 2 weeks is envisaged for this purpose.

( ii i) The crane is scheduled to leave the factory on 19th January. The Liebherr Logistics Manager is still

working on a plan for delivery to Jersey. Approximate arrival in Jersey is expected mid February.

( iv ) The Victoria Quay will be used for a period to unload liner service vessels whilst work is carried out on the New North Quay. This is already a working berth for other services and as such is kept available for commercial bookings made. The west cross area will be kept clear during this period. There are no

permanent berths allocated in this area. Vessels moored there are allowed to do so on the understanding that they

must move for operational vessels.

Question

2. Would the Minister inform memberswhether the crane that was inadvertently draggedup the VictoriaQuay by the LogosIIis still in a usable state to unload freight?

Answer

During the berthing incident involving Logos II one of the harbour cranes was contacted by the bow and pushed a short distance down the quay. Damage sustained was superficial and repaired within 24 hours. The crane was subsequently inspected and has been in use ever since.

Question

3. Would the Minister inform memberswhatimprovements,ifany, have been carried out on the VictoriaQuay to ensure the safe boarding of vessels on that quay, particularly adjacent to that part ofthe quay near the ice- machine?

Answer

There is a half tide ladder provided for boarding vessels on the London Berth. Previously fishermen had attached an unsafe appliance to the bottom of this, which has now been removed. Following consultation with HSI signage has been placed by this ladder giving warning of its limitations. Jersey Harbours is in the process of placing additional pontoons  along this berth  for  use by fishermen. This  project is underway now. Access to these pontoons will be via the stems in the corner of the berth.
