3 Raytheon Marine GmbH High Seas Products BV Der Engländer JOHN HAMILTON MOORE beschreibt erstmals eine Logge mit nachschleppbarem Holzscheit (englisch =„log“) und einer auslaufenden Leine, zusammen mit einem „Glas“ (Sanduhr), das 28 sec. lang läuft. Die Logleine ist in Abständen mit Knoten markiert.

4 Raytheon Marine GmbH High Seas Products BV „WALKER“ -Log:

5 Raytheon Marine GmbH High Seas Products SAL - “Svenska Aktiebolaget Logg” The first SAL-Log Installed 1913 on the swedish vessel HYPERION

6 Raytheon Marine GmbH High Seas Products Correlation SAL-Logs from Consilium Navigation (first accustical Log installed in 1972) SAL T2 Gate valve: 24kg, Transducer, Indicators, Electronic unit Gate valve: 75kg, Transducer, Indicators, 2 Electronic units Single axis Log (4 MHz) only WT Dual axis Log (4 MHz + 150kHz) WT and BT

8 Raytheon Marine GmbH High Seas Products SOLAS / requirements Regulation 18:“Systems and equipment required to meet the requirements of reg.19 and 20 shall be of a type approved by the Administration. Regulation 19, 2.3:“All ships of 300 gt and upwards and passenger ships irrespective of size shall …. be fitted with: speed and distance measuring device,or other means, to indicate speed and distance through water.” Regulation Speed & distance measuring device over the ground forward and athwartship for all ships of gt and upwards

9 Raytheon Marine GmbH High Seas Products Rules, regulations and directives The European Marine Equipment Directive, CE-, ”Wheel”-marks and IMO requirements for speed logs. IMO A.824(19) - Recommendation on performance standards for devices to indicate speed and distance IEC (MSC.96(72)) - Speed and distance measuring device through water IEC Environmental and general requirements IMO A.823(19) Log and speed indicators providing inputs to ARPA/ATA equipment shall be capable of providing the ship’s speed through the water in the fore and aft direction.

10 Raytheon Marine GmbH High Seas Products Resolution MSC.96(72) (i) (adopted on 22 May 2000) Recommends Member Governments to ensure that: (a) Devices to measure and indicate speed and distance installed on or after 1 July 2002 conform to performance standards not inferior to those set out in the Annex to the present resolution. Introduction 1.1 Devices measuring speed and distance through the water should meet the performance standard in water of depth greater than 3 m beneath the keel. Devices measuring speed and distance over the ground should meet the performance standard in water of depth greater than 2 m beneath the keel. Accuracy of measurement Errors in the measured and indicated speed, when the ship is operating free from shallow water effect and from the effects of wind, sea bottom type, current and tide, should not exceed the following: 1 for a digital display - 2% of the speed of the ship, or 0.2 knots, whichever is greater; and 2 for an analogue display - 2.5% of the speed of the ship, or 0.25 knots, whichever is the greater; and 3 for output data transmission - 2% of the speed of the ship, or 0.2 knots, whichever is greater.
