2 Introducing of requirements

2.1 General

The main objective is to replace the actual crane of main deck L’Atalante R/V by a knuckle crane « marine » type designed to launch and recover onboard systems. It will be implemented on the stern working deck, on port side. The crane will be used at quay side or at sea for general handling operations with appropriate kinematics (Appendix 1). Special attention shall be paid to equipment robustness and reliability.

2.2 Scope of supply

Manufacturer shall supply Ifremer with the following items:

the drawing, computing notes, operator manual and maintenance instructions and certifications.

Anything in this specification that is not expressly stated as being Ifremer supplying and which is specific and required for using the crane shall be supplied by Manufacturer. All those equipment shall be powered using onboard electrical supply to ensure their good operating state.

2.3 Description of the environment

Crane can be operated by 5° ship static list. The crane will be used in marine conditions (continuous service) with following considerations:

Summer conditions are seawater at 32 °C, air at 35°C and maximum hygrometry of 90%. Winter conditions are sea water at -2°C, air at -15°C.



3 Design and building requirements

1 coat of 75µ of ETHYL SILICATE DE ZINC 1 coat of 60µ of EPOXY SEALER 2 coats of 100µ (each) EPOXY ANTICORROSION 1 coat of 50µ POLYURETHANE FINITION 1 coat of 50µ INTERTHANE 990

The utmost care shall be provided to prepare surfaces and apply coats of protective paint. The Manufacturer shall detail to Ifremer its painting marine standard and it shall be compliant with Ifremer standard. All eyes plates for rigging as well as various support and electrical cabling protection pipes are to be welded before sandblasting. Articulations are to be so arranged that no corrosion appears.

3.1.2 Electrical interfaces

Electrical equipment and hardware shall have at least the following safety degree:

IP56 in wet rooms, IP67 on weather decks.

Electrical motors shall have at least IP56 safety degree, insulation class F and acceptable overheating 80°C.

The cleaning of hydraulic pipes will be conformed to cleaness grade 6 according to SAE AS 4059. Hydraulic outlets will be type:

quick coupler STAÜBLI type CBX or SPX, screw union STAÜBLI type will be defined.

In order to protect the staff, contact with surfaces which have a temperature higher to 55°C will be not possible. A system of oil preheat will be supplied if necessary, as well as cooling system for summer periods. All hydraulic piping system shall be uncoupled and STAUFF mounted. Hydraulic fittings shall be well protected against corrosion.



3.2 Dimension and structure requirements

3.2.1 Structure requirements

During studies, Manufacturer shall inform Ifremer of loads transmitted to the main structure and shall detail mechanical interface with the vessel using detailed drawings.

3.2.2 Weight requirements

Weight requirements are key criteria due to constraints imposed by on board installation. Manufacturer shall make efforts to design a crane as light as possible. The manufacturer shall design a crane as light as possible (target weight is 35 T maximum).

3.2.3 Load curve

During studies, Manufacturer shall give to Ifremer the load curve in accordance with functions defined in paragraph 4.

3.3 Interfaces

Manufacturer shall build a coordination plan stating all interfaces and their specifications.

3.3.1 Mechanical interfaces

Crane will be fixed on the deck D, centred on the existing pedestral (see appendix 3). Manufacturer shall define appropriate mechanical interface and give to Ifremer loads which are transmitted to the deck following use cases. Above deck D, diameter of pedestral shall be 2000 mm maximum. This dimension is a key criteria of requirements. Modifications of pedestral between deck C and deck D are not included in the scope of supply.

3.3.2 Electrical interfaces, high currents

The electrical power source onboard the vessel has the following characteristics (impedance earthed system with isolated neutral and not distributed): 380 V, 50 Hz, 150 kW available.

Power needs requirements are key criteria due to constraints imposed by on board installation. Manufacturer shall make efforts to design a crane which its necessary power is as near as possible at 150 kW. Manufacturer will precise if he needs more power to respect main crane functions (§4).

3.3.3 Electrical interfaces, low currents

Cables required for scientific data and crane control networks are internal to the crane's system and don't require any specific interfaces. The electro-magnetic influence shall be minimum.



4 Supply description

4.1 Main functional of crane

The knuckle crane will be used at quay or at sea for general handling operations with appropriate kinematics (Appendix 1). It will integrate a cabin with all necessary functionalities for safe and comfortable control and will be equipped with two hoisting winches, named Main winch and Auxiliary winch. The system shall be dimensioned and approved for operations at quay and at sea. It will receive BV ALP and ALM marks (following duty category III of NR526 DT R01 E) or DNV equivalence. The crane will be designed for continuous services in the defined range set up for the deployment of systems at sea state 6. The technical performances of the crane and its winches should be defined in followed paragraphs.

4.1.1 Crane and winches

minimum to 20m at sea.

0-35 m/min lifting speed.

Steel non rotating cable, at least 40 m.

A standard hook will be supplied at the end of the cable. A standard tackle is acceptable. The Manufactuer shall be proposed two options:

Option 1 : a constant tension at 60m/min

Option 2 : a passive compensator used during sea/air passage to absorb shocks and dynamic

loads. The effort compensation value shall be adjustable.

Lifting capacity – auxiliary winch : the winch is used to handle package less than 2T with

appropriate cable size and hook (rubber boat for example). No constant tension is needed. 2 T from minimum to 20 m at sea.

0-30m/mn hoisting speed at 2T and at sea.

Synthetic rope, minimum length of 40m.
