2017-10 DWR4 0.7m

With the introduction of the 0.7m DWR4 we have had to reconsider the design of the chaincoupling for this buoy. The standard chaincoupling does not suffice because it is too heavy for the relatively light buoy. The eccentric mooring eye in combination with the relatively heavy chaincoupling would unbalance the buoy. To reduce the weight of the chaincoupling, we have decided to use 4 16mm links on the chain instead of the standard 10 20mm links reducing the underwater weight by 50%. With this decision it is important to note that chains for 0.9m and 0.7m DWR4 buoys are no longer interchangeable. The DWR4 0.7m with or without current meter is now available for rent as well.

Many Waveriders we supplied have been equipped with a Superstar GPS receiver. Recently it has come to our attention that the Superstar generates a faulty date in the logger files. The problem can be explained by an unexpected “GPS week rollover”. The internal date obtained from the GPS satellite system is incorrect. Typically the date is set to the year 2096. To convert the incorrect data we are currently developing a software tool. The only solution to this problem however is to replace the Superstar GPS receiver. The Superstar position module must be replaced with the µBlox GPS receiver (DWR-MKIII and WR-SG). The µBlox GPS receiver was introduced in the beginning of 2012.
