This however, does not apply to the lower hoist limit switch when the hook is in the sea lift zone. 2.46

Crane recording system

2.46.1

General

2.46.1.1 Main functions The crane shall be equipped with a recording system, which is connected to the crane’s control- and load indicator system (PLC or crane computer). The recording system is communicating with the control system and makes it possible to store parameters of importance in memory. The recording system shall have three main functions: 1. The recording system shall store information about how much the crane and the machinery have been used and the load on the crane structure. The S.W.P. (safe working period) for the machinery shall be calculated, the total number of load cycles that have been done and the load class the crane belongs to, based on the actual use of the crane. The information shall be shown on a display1 that is connected to the system. 2. Data for fatigue calculations of critical components shall also be stored and be available in order to carry out such calculations. 3. In addition there shall be a condition recorder that continually records various data, where the purpose is to be able to repeat the crane’s running condition for a defined period in the past. 2.46.1.2 Equipment The equipment for recording shall record data continually without any need for manual routines to update the data sets, i.e. the recording equipment shall be able to automatically load and store the data necessary to display history, doing fatigue calculations and storing data to the condition recorder.

The recording system may be a part of the crane’s programmable control system and/or a separate unit(s) for recording and showing the recording data. The system shall be equipped with a screen and shall contain software to display historical information about the crane. The screen shall be a part of the system and may be permanent or easily connected to the system when needed. The system’s time reference must be available and easy to adjust. The main motor(s) shall have an hour counter even if that is included in the recording system. The recording system shall be supplied from the same power source that supplies the crane’s controland load indicator system. 2.46.1.3 Storing of data The recording system shall have enough storage capacity to keep the recorded data in the crane’s operating life time, without having to down loading files etc. to release space in the system’s memory. However, the system shall have back-up features and have restore capabilities to replace damaged files etc. from old back-up sets. The recorded data should be accumulated in tables and stored in a limited number of files. 2.46.1.4 Communication errors If communication between the programmable control system and the recording system is lost, this shall be indicated on the control panel. This applies also if storing of data to files is not completed. These errors shall however not prevent the crane driver from operating the crane. 2.46.2

Functions

2.46.2.1 Presentation of historical data The recording system shall at any time have the possibility to present a summary of exposed load on the crane structure and crane machinery. This summary shall be presented as information about the actual duration of service of the machinery (minimum for the hoist-, boom- and slewing machinery) and information about the load on the crane’s structure. The actual duration of service for installed cranes is to be calculated with methods described in FEM 9.755 (06.93). If a new recording system is installed in these cranes, the results from this calculation, are to be set as initial values into the new recording system. It shall be possible to view the information on the system’s screen without downloading or moving any data from the system, i.e. the summary has to be a report generated from the recording system’s software. It shall be possible to export this summary to a file, which format easily can be read by for example a spreadsheet. A table showing minimum the following information shall be available on the screen: General: • Number of days since crane became operational • Number of days the crane has been used • Total number of start / stop sequences of main motors • Running time for main motors in hours

This information shall be stored in the recording system during the whole operational time of the crane. Data for calculation of fatigue is based on storing one post of data each lift cycle, i.e. one set of data is generated when each lift cycle is finished. This gives detailed information about the lift cycles carried out by the crane and will give reliable calculations of fatigue, and can be used as a basis for other analysis.

Fatigue calculations and implementation of other analysis can be executed on another computer then the one which is doing the recording. In that case data have to be copied from the recording system to the other computer before the calculations can take place. 2.46.2.3 Activity recorder The activity logger shall store values for all important signals entering the crane control unit, including calculated variables in the control system containing important information. The main purpose with the activity logger is the possibility to analyze special events such as engine failure or crane accidents. The values thus shall be recorded fast enough to ensure that important events or conditions are captured. Such conditions may for instance be overload situations, irregular high / low pressures in the hydraulic system, use of override switches etc. The activity logger may consist in a separate unit or can be embedded with the recording system. The activity logger shall store data when the crane is in use4, and shall as a minimum, store information for the last 24 hours5 of operation. When the logger is full, the oldest data shall be deleted first such that the logger always keeps information of the last 24 hours of operation with the crane. It shall be possible to export data out of the activity logger for a later graphic presentation with dedicated software. If asked for by the Company, the software performing this presentation shall be delivered with the recording system. 2.46.3
