The davit system is designed for long time operation in a tough and corrosive marine/offshore environment and to futfl all requirements as given in latest SOLAS/IMO requirements. The system will allow: = Hoisting and lowering of the fully loaded rescue boat up to 20° list and 10° trim. ~ Gravity lowering of the fully loaded boat up to 20° list and 10° trim, completely independent of any power supply. - Hoisting of the loaded rescue boat by electric motor. & VIKING “VIKING Project No.: Standard ‘VIKING Doc.

No: 7= Dead ship slewing of the rescue boat by the nitrogen accumulator installed on the davit arm. - Retrieval of the rescue boat by manual hoisting, - Manual slewing by hand pump. The davit system has a hydraulically driven, mechanical slewing jib and an electric driven winch with single wire fall. Slewing and dead ship slewing functions are driven by a small hydraulic power pack. The hydraulic system is equipped with a stored power unit - which allows full operation of the davit in “dead ship” conditions. The davit is designed to achieve optimum performance in terms of safety and reliability, and minimal maintenance levels. All selected equipment is chosen and installed to ensure the lowest possible ‘emission of sound and for good access for service and repair. A HPU is included, and is located inside of the davit pedestal. All internal hydraulic piping is properly done and completed on the entire davit system, A remote control for start/stop of el motor on HPU as well as hoisting and slewing control is also included. When the button is released, davit operation will cease immediately. A thermal overload relay in the starter cabinet protects the electrical motor against overheating in case of excessive loads. A safety valve is installed in the hydraulic power unit. This safety valve prevents the davit from slewing loads in excess of the Safe Working Load and protects the system and motor from being overloaded, The winch is fitted with a one-way clutch. In the event of power loss during hoisting, the brake will automatically activate and davit motion will stop. A centrifugal brake is located on the winch. The brake controls the speed of descent for the lifeboat. The brake is enclosed, and provides reliable operation in all climate conditions. Electrical limit switches are used to cut power to the winch, if the boat is hoisted above stowage height, Electrical limit switches will prevent the boat from being hoisted above its upmost position / stowed position. Electrical limit switches on the winch provide failsafe operation of the hand crank. For launching in dead ship conditions, stored power from accumulator and gravity lowering system in winch provides safe launching, Starter cabinet is mounted on HPU as standard. All electrical cables for davit control, included 42V AC to rescue boat when that is needed is installed and terminated by VIKING Norsafe. Only main power supply is required 2.2 WINCH AND WIRE Type DW-25 winch Drawing reference Ds-00712 Electrical hoisting and lowering / Gravity lowering / Execution Manually hoisting / Manually fast hoisting Brakes type Centrifugal brakes Wire rope type Galvanized, rotation resistant (certified item) VIKING VIKING PojetNa:Standats ——-VKING Dos.
