  • Page 14: About Trawl Positioning

    About Trawl Positioning This topic explains how the position of the trawl is calculated. Angles are relative to the stern of the vessel. Angles toward port side are negative and angles toward starboard side are positive. The distance is calculated from the warp lengths sent by a winch control system. Scala2 application can calculate the positioning of the trawl from this distance, the depth and bearing angle.

  • Page 85: Installation

    Installation Learn how to install the sensor on the trawl gear. Installation Principles Door sensors need to be installed in pockets welded on trawl doors. Carefully read these installation principles before installing sensor pockets. Angle of Attack The angle of attack is the angle of the door in relation to the towing direction. This angle is important for the efficiency of the doors.
  • Page 86 Opening and Elevation Angles The opening and elevation angles depend on the pocket installation on the door. The opening angle is the horizontal angle of the pocket in relation to the door. It should be between 25° and 40°. Opening angles should be in line with the angle of attack. You need to indicate the opening angle on Mosa2.
  • Page 87 1. Elevation angle: 15-20° Roll Angles Roll angle of the sensors depends on the tilt of the doors when fishing. If doors are straight during fishing, you can apply a roll angle of 90°. If doors are tilted inward during fishing, slightly Spread Sensors Pro | V4 | Installation...
  • Page 88 roll the pocket so that lines of communication between the sensors stay aligned. If not, you will have sporadic spread readings. 1. Adapt roll angles of pockets according to the tilt of the doors. PRP & Digital Spread Communication Spread sensors communicate with each other and with the receiver. Lines of communication between them and toward the receiver must be unobstructed.

Adjust accordingly to the elevation angle and angle of attack you need (see Pocket Angle of Attack (on page 126)). Picture below shows angles of attack seen from above the door.
  • Page 92 a. Weld only a few points on two sides of the pocket to hold it on the door. b. Slide the sensor into the alignment bar inside the door pocket. You can adjust the roll of the sensor using the alignment bar (see Pocket for XL Bottles (on page 127)).
  • Page 93 8. We recommend to use a protective cage made of metal bars around pockets to protect sensors, like the examples below.

    Check the baseline dimensions you entered in the positioning settings (on page 53) in the system web page (or Scala2 receiver page). The vessel and trawl have erratic movements: they jump, zigzag, move forward and backward You have two GPS inputs. Coordinates can be slightly different between the two GPS so the position of the trawl changes according to one or the other.

  • Page 111 C-7/CH6 40469 Frequencies and intervals The diagrams below show the bandwidth of the different types of Marport sensors and intervals you must respect when adding other sensors. PRP sensors (e.g. Catch sensor, Trawl Speed, Spread sensor...) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.9 and 40.1kHz.
  • Page 112 Marport Pro sensors (e.g. Trident, Door Explorer, Door Sensor Pro, all Navigator range except Catch) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8 and 41.2kHz.
