Norway's Reach Subsea has extended a charter for a light construction vessel owned by Ostensjo Rederi.
The 2,800-dwt Edda Fonn (built 2003) will stay with the Oslo-listed company until the end of 2018.
The deal has also been renegotiated, but commercial terms are staying confidential.
The ship is currently scheduled to begin a contract starting on 9 July. This will last for 20 firm days, with 20 days as options.
