Andresen was born in Kråkstad. He was a regular on many Norway national youth teams while playing for Moss, Viking and Stabæk Fotball from 1995–1999. After the 1999 season, Andresen was sold to Premier League club Wimbledon in a deal worth £1 million. But like many of the other Norwegians in the club, his stay became short and unsuccessful. He scored once for Wimbledon; in a 2–1 loss to Liverpool. After a short loan spell at Molde, Andresen returned to his motherclub Stabæk in 2001, where he proved himself to be one of the best central midfielders in Norway. After a brilliant 2003 season, where Stabæk captured the bronze medals in the Norwegian Premier League, Andresen was loaned out to the Premiership club Blackburn Rovers for six months in 2004, from February to August, but did not sign a longer deal with the English club. Andresen return to Stabæk to save the club from relegation from the Norwegian Premier League. Andresen played while injured and Stabæk could not save their top spot in league Norway. Andresen, not willing to play in the Adeccoliga, asked to be sold. Many clubs in Norway were interested in the national teamcaptain; the high price scared many away, including the champions Rosenborg. Vålerenga looked set to capture Andresen at Christmas 2004. Brann was helped by local investors to sign him on 23 December 2004.
Brann
Andresen became the most expensive transfer in Brann history, in a deal worth ca. 15.000.000 NOK. After a disappointing first season, much ruined by injuries, Andresen made it clear that he would be "fit for fight" in 2006. In the pre-season he was appointed captain for Brann, clearly showing his importance for the club on and off the field. In 2006, Brann had their best season opening ever, with Andresen filling the captain role. He also periodically captained team Norway, playing in central midfield. In 2007 Brann won the Norwegian League, with Andresen as captain. He was described as the most valuable player by many Norwegian pundits. He was also named in the Team of the Year.
Vålerenga
Andresen was announced as the new manager of Vålerenga on 6 November 2007 while still under contract with Brann for the remainder of the year. Brann terminated their working relationship with Andresen the day after. He signed a three-year-long contract with Vålerenga as player and manager. Andresen became the first player/head coach in Norway's top division since Kjetil Rekdal in 2002. He retired as a player before the 2010 season, but continued to play several matches for the reserve team in the Norwegian Second Division. In 2011, he played for Follo FK who were in the same division, making eight appearances for the club. On 15 October 2012, Andresen was dismissed as manager for Vålerenga.
Stabæk
He came out of retirement and joined Stabæk, who had been relegated from Tippeligaen, ahead of the 2013 season.
Sandefjord
He came out for retirement for a second time on 18 August 2015, and joined Sandefjord Fotball for the remainder of the 2015 Tippeligaen season.
International career
He made his debut for Norway in a 15 August 2001 friendly match against Turkey and has earned a total of 43 caps, scoring 3 goals.
