Husavågen: Submarine installations under constructionSubmarine power cables and water supply pipelines are being constructed in Husavågen. Once completed, they are meant to run between Tråvik and Grønnevika.
Several work vessels may operate in the vicinity of position 59° 59.9′ N, 5° 48.3′ E (WGS84). They may display ball–diamond–ball or other signals according to COLREGS. Work vessels include:
Mariners are cautioned against all seabed activities in the works area, particularly fishing and use of the recommended anchorage close by.
Husavågen: Overhead Cable ClearanceThe overhead power cable at the following position has been surveyed to have a physical vertical clearance of just 5.8 m over high water (HAT).

Chart NO 20: New Edition (NE)Chart NO 20 “Sunnhordlandsfjordene” has been published as a New Edition (NE) by Kartverket on 26 April 2019.
This New Edition cancels the previous edition (published in 2015). However, it does not contain any changes significant to navigation, therefore it does not make the 2015 edition obsolete and it may safely be treated as a Revised Reprint by pleasure craft not required by law to carry up-to-date official charts (e. g. Forskrift om navigasjonshjelpemidler / SchSV Anlage 1 C.I.4.3.).
Comprehensive list of changes in this (Limited) New Edition:
T).While the 2015 edition may safely continue to be used for navigation, obtaining this updated version of chart NO20 is still recommended even for pleasure craft: Occasionally geographical names are spoken or spelled (for example when reporting positions by radiotelephone), and it is useful that all parties involved in such communication use the same reference for such names. Considering that, it would seem sensible for all chart users to obtain this New Edition at their earliest convenience in spite of the lack of changes significant to navigation.
